The Ultimate Buyer’s Guide To Home EV Chargers: Plus Top 5 Picks

DEC 15 2018 BY TOM MOLOUGHNEY 73

You’ve got questions, we’ve got your answers.

Only a few years ago there were very little choices for electric vehicle charging equipment. When I got my MINI-E in 2009, BMW partnered with ClipperCreek to supply the home charging station, or as BMW called it, the “Wallbox” to charge the fleet of 450 MINI-Es in service in the US. Tesla also reached out to ClipperCreek back in 2008 to supply the charging equipment for the initial Tesla Roadsters. Neither company really had any choice, because at the time ClipperCreek was pretty much the only company that could deliver this specialized EV charging equipment.

A lot has changed in 10 years in the world of electric cars, and also in EV charging equipment. ClipperCreek is still around, and is still one of the top companies providing electric vehicle supply equipment, or “EVSE”. Electric vehicle supply equipment is really the proper term to use, but the general public really hasn’t warmed up to that, and most people call EVSEs “charging stations”. The reason charging station is not really the proper term is because the actual charging equipment is built into the car, and the EVSE really just provides a safe supply of electricity to the vehicle.

However, we’ll use the term “charging station” here since that’s what most people recognize the equipment as, and so those new to electric cars won’t get confused. It’s also important to note that this post is specific to the North American market. The electricity supply in Europe and most other parts of the world doesn’t use 120-volts as their standard household current as we do here, so there is no “level 1 charging”. Also, in Europe the charging cable is often not tethered to the unit for Level 2 charging, and thus, the equipment is very different than what is used in North America.

A BMW level-1 portable charger. These are provided with every BMW plug-in vehicle sold or leased. *Notice a standard household plug is used.

Level 1 or Level 2 – What’s the difference?

Every electric vehicle sold today comes standard with a 120-volt Level 1 portable charger. These chargers can be plugged into a simple household outlet, and don’t require any special installation. Some manufacturers, like Tesla’s cars for instance, come with a plug-in 120/240-volt Level 1/2 charger. These require a 240-volt outlet, which most owners need to have installed.

However, most manufacturers only provide a basic Level 1, 120-volt charger, and offer as an option, a higher-powered level 2 unit for sale. In order to recharge their EV quicker, many owners choose to buy a 240-volt, Level 2 charging station and install it at their home. This goes for basically all electric vehicles other than Tesla. Tesla is unique in that they use a proprietary connector, that only they use.

Every other electric vehicle made today uses the same connector for level 1 and level 2 charging for that specific market. So, there’s one plug for North America that everybody besides Tesla uses, and it’s called the SAE J1772, and another plug that everyone uses in Europe called the Type 2. We mention this not to confuse the readers, but to assure them that any charging station they purchase in their native market will charge their electric car, they do not need to worry about buying the “wrong one”. Aditionally, Tesla vehicles can also use any level 1 or level 2 charging station because Tesla provides an adapter with every car. These adapters allow Tesla to use charging stations with the J1772 connector.

Level 1 chargers will deliver between 3 and 5 miles of range per hour to a typical electric car. For level 2 chargers the rate increases to a range of between 12 and 60 miles per hour. However, that number will be limited to how much electricity the car’s onboard charger can accept. The car is always in control of how much electricity it takes in, so you won’t damage the vehicle if you buy a charging station that can deliver more power than the car can accept. In fact, many people choose to buy a charging station that can deliver more power than their current EV can accept, so they’ll be ready if their next EV can charge at a higher rate.

There are low-powered level 2 chargers that are small and portable. Many of these are limited to a power delivery of 16-amps to 20-amps. These units will charge a typical EV at a rate of about 12 to 18 miles per hour. We’ll be doing a side-by-side comparison post here on those portable units soon, but today we’re going to focus on the best choices for medium-powered, wall mounted charging stations.

These units typically deliver between 30-amps and 40-amps, and will charge a typical EV at a rate of about 25 to 35 miles per hour. Most of today’s wall-mounted level 2 charging stations come in both hard-wired and plug-in versions, which we’ll discuss later. But before buying a Level 2 charger, there are a couple things you should consider.

A lower-powered portable level-2 charger. It’s about the same size as a portable level 1 unit, but can deliver much more power. *Notice a NEMA 14-30 240-volt plug is used.

Considerations Before You Buy

  • Are you in control of your electricity supply? If you own your home, then there’s no issue because you can install your charging station without needing asking for permission. If you own a condominium, you will probably have to get permission from the association, which can be troublesome. If you live in an apartment and have a reserved parking space or garage, you’ll likely need to get the landlord’s permission before installing the charging station, and there may be a limit on how much power is available to you in the garage.
  • Does your electric service panel have enough spare capacity to allow you to install a dedicated circuit for the charging station? If you have any question about whether or not you have enough spare capacity, consult a licensed electrician to inspect your service to let you know if you do.
  • Where would you like it installed? You should locate the charging station close to where the inlet for the connector on the car is, and make sure the cable on the charger is long enough to reach the inlet without stretching. Every EV has a different location for their charge port, so make sure you know where your charge port is located before installing your charging station.

Once you’ve confirmed that you can install the charging station and you know where you want it, it’s time to decide which charging station to buy. There’s many choices available today, and not all charging stations are created equal. Let’s look at the different features that should be a consideration when deciding on which station is the right one for you.

Power: Level 2 charging stations typically deliver anywhere from 16-amps to 80-amps. This can make a huge difference in how quickly your EV charges. You probably don’t want to buy an underpowered charging station, only to need to buy a more powerful at a later date. Even if your current EV can only accept 16-amps (3.3kW) you might want to consider getting a more powerful unit, because your next EV will likely accept at least 32 amps (7.7 kW) For that reason, we recommend getting a charging station that can deliver at least 32-amps, preferably 40-amps if you want to future-proof your investment.

Cable Length: Some charging stations come standard with only a 16-foot cable. In our experience, that’s not long enough for most people. We recommend making sure the cable length is at least 20 feet in length, with 24-25 feet being ideal.

Safety Certified: Since electric vehicle charging is a relatively new industry, there are a lot of small start-up companies making EV chargers, some of which haven’t taken the time or expense to have the device safety certified by an established testing entity like Underwriters Laboratory (UL). These devices will be delivering a high amount of power to your car every day, and for many continuous hours. You want to make sure it has been fully tested and certified. We do not recommend buying any charging station that doesn’t have the UL certification seal on it.

Hardwired or Plug-In? Hardwiring simply means the unit is permanently connected to the electric supply, so you cannot remove it without opening the charger up and removing the wiring. A plug-in unit isn’t permanently connected to the electric supply, it simply plugs into an electrical receptacle.

There are a few advantages to having a charging station that plugs in, as opposed to permanently installed:

  • You can unplug the unit and take it with you to charge at another location. Perhaps you have a 2nd home, or visit family or friends that live far away. You can take a plug-in unit with you on long trips, but you cannot take a hardwired one. These aren’t as small and as light as the lower-powered level 2 portable chargers, but they can be easily removed and taken to another location.
  • Installation can cost less. Since all you need to have your electrician do is install a 240-volt outlet, the installation can be much less than if they have to hardwire and install the charging station.
  • Since all you need is an outlet, you can have it installed before you buy the charging station, and have your garage ready to go when the charging station arrives. If you do this, make sure you have your electrician install a circuit that can deliver at least 40-amps, 50-amps would be even better.
  • If there’s a problem with it, and you need to have it repaired or replaced under warranty, you just unplug it and ship it back. If it’s hardwired, you need to have your electrician come to remove it, cap the wires, and then come back to reinstall the new one.

Outdoor Rated & Connector Holster

 Many people don’t have a garage to park their EV inside, so their charging station has to be mounted outdoors. Make sure the station is outdoor rated, but that’s not the end of the story. The charging stations usually have either a NEMA 3 or NEMA 4 rating. Both are acceptable for outdoor use, but NEMA 4 adds a little more protection and adds protection against a direct blast of water from a hose. This could be useful in areas that get blowing rain or wind-driven snowstorms.

Some charging station have a built-in or remote connector holster so the plug is protected while not in use. Other stations just direct the customer to drape the cable over the body of the unit and leave the connector hanging and unprotected. We recommend making sure the connector is properly protected when not in use. This will keep dirt, water and other contaminants from entering the connector and possibly damaging it.

Smart or Dumb?

A “dumb” charging station just charges the car, period. And for some owners, that’s all they care about.  A smart charging station has the ability to connect to WiFi or PLC and allow the owner to monitor their charging, check the power being delivered, review statistics from past charging sessions and more. This allows the owner to see exactly how much energy the car is using, so they can calculate how much the car costs to power. Without this feature, an EV owner can only guess how much the car is costing them to charge.

Some smart chargers can perform other tasks, like connecting to Amazon Alexa for voice-control of your charging, communicating with your utility so you can charge your car when the electricity provided is the “greenest” available, and even load-share so you can have two chargers on one dedicated circuit. If you want options like these, or you’re kind of a data-geek, you’ll definitely want a smart charging station.

Cost

 You can expect to spend somewhere between $400 and $1,200 for a high quality, safety-certified electric vehicle charging station. However, spending more doesn’t always get you more. We’ve also noticed many of the charging stations listed below often have special offers and discounts, so shop around a bit before you make a purchase.

For some, the least expensive charger that’s built well and has a good warranty is the right choice, and we have a top pick recommendation that fits that profile. For others, having the ability to review charging session history, calculate the exact cost of charging, using Amazon Alexa to voice control your charging and other smart-charging options are worth the extra cost, and we offer our top pick for these higher-end smart-chargers also.

A variety of wall-mounted level 2 charging stations

Recommendations:

The charging stations below are some of the most popular on the market today, and we can confidently recommend all of them. They are all safety certified and have very high customer-satisfaction ratings. After considering all of their features as well as the cost, we ranked them in descending order.

However, it’s important to note that all of the units here are a solid choice if they meet your personal qualifications. In our opinion, all of the chargers listed below are better choices than many other charging stations on the market today.

And our top recommendation is…

JuiceBox Pro 40

#1: JuiceBox Pro 40 by eMotorWerks: The JuiceBox Pro 40 is our Top Pick for a number of reasons. First, it delivers up to 40-amps of power, while the main competition is limited to 30 or 32-amps. If you don’t want the extra power, the JuiceBox Pro 32 is available for about $80 less and has all the features of the Pro 40. It comes standard as a plug-in unit, it has a NEMA-4 rated outer case for extra protection from the weather, a 24-ft cable is standard, and it’s WiFi-connected with an app that has the most smart-charging features available. You can de-rate the power delivery, set reminders and notifications, and even use Amazon Alexa voice control.

The JuiceBox is also the only EVSE on the list that allows load-sharing, which allows the owner to use one dedicated circuit for multiple units. This can be very useful for two-EV families. Basically, it checks all the boxes. It costs less than the other stations yet has more features which is why it earns the top spot. Also, the JuiceBox along with the ChargePoint Home are the only Energy-Star certified units on the list.

Cost: $579.00 (The 32-amp JuiceBox Pro 32 is $499.00)

 

ClipperCreek HCS-40

#2 ClipperCreek HCS-40P ClipperCreek has been making EV charging equipment longer than any of other company, and has built a reputation for making extremely durable, reliable charging stations. The HCS-40 is a “dumb” charger and is available hardwired or as a plug-in unit. The HSC-40 can deliver up to 32-amps, and comes standard with a long 25-ft cable. The outer casing is NEMA-4 rated for extreme weather and like the JuiceBox, it comes with a remote connector holster which allows the owner to locate it wherever they choose. Many owners like this option, so they can locate the holster on the wall directly opposite their charge port, even though the charger may be further away.

The HCS-40P is physically the largest unit on the list, which may be a consideration if you have limited wall space. ClipperCreek’s reputation for high-quality & durable units is well earned, and they have a very loyal customer base. I’ve personally used their products for years, and have never been disappointed.

Cost: $589.00

 

#3 ChargePoint Home 25 ChargePoint manages the largest network of public charging stations in the US. They entered the residential charging stations market in 2015 with the introduction of the ChargePoint Home. The Home is a WiFi-connected smart charger and offers real-time charging data, the electricity cost of each session, as well as previous charging history. It is available as a plug-in, as well as hard-wired unit. Like the JuiceBox, you can sync the Home with Amazon Alexa to remotely start, schedule and stop charging sessions and it’s also Energy-Star certified. The ChargePoint Home delivers up to 32-amps, and has a NEMA-3 outer enclosure, that is suitable for outdoor use but offers a little less protection from the elements than some other units that are NEMA-4 rated. There’s a built-in connector holster with a nice LED light to help center the connector when holstering it.

The ChargePoint Home is the smallest and lightest unit, with a very sleek design and pivoting connector holster in the center of the body. You won’t be disappointed if you choose to buy the ChargePoint Home

Cost: $674.00

 

Siemens VersiCharge™

#4 Siemens VersiCharge 30GRYU The Siemens VersiCharge is the least expensive charger on the list. It’s a basic, no-frills “dumb” charger that comes in a plug-in version as well as hardwired. Like the ChargePoint Home, it has a connector holster located on the center on the unit and is available in different cable lengths. It has a NEMA 4 rating for top weather protection. The standard cable length is a very short, 14-feet, so if you order the Siemens VersiCharge, make sure you order the cable length that you need. If you’re in the market for the most economical level 2 unit that’s safety certified, plugs in and has a NEMA 4 rating, then this might be your best choice. For that reason, it’s our Top Pick for a low-cost basic, charging station

 Cost: $458.94

 

AeroVironment / Webasto

#5 AeroVironment/Webasto EV Charger Earlier in the year, AeroVironment sold their EV charging division to Webasto, which is the reason for the dual-name above. AeroVironment had been making this popular charging station since 2010, and it has proven to be an extremely reliable unit. BMW, Ford, Nissan and others all chose AeroVironment at one time or another to be their official charging partner and used this unit. It is a “dumb” charging station and is available in hardwired or plug-in versions and delivers 32-amps. Like the ChargePoint Home, the outer casing is NEMA-3 rated, so it has a little less protection from the elements than the other three units on this list. This charging station was once a top choice, but it hasn’t upgraded or improved in eight years, so the competition has passed them. However, it’s still a solid choice if it fits your needs and budget.

Cost: $589.00

Closing

It’s important to note that because these charging stations come in different configurations, cable lengths and plugs, we added optional features on each unit to make the price comparison fair. Basically, we wanted a medium-powered (30-amp to 40-amp) plug-in unit, that had at least a 20-foot cable.

Also, all of these charging stations come with a 3-year warranty and have been thoroughly safety-certified. That isn’t the case with all charging stations, as some budget offerings only have a 1-year warranty and haven’t been independently tested for safety, so buyer beware. Like anything else, if it looks too good to be true, it probably is.

We’ve also listed what we see as the “regular price”, which is the price these units usually sell for. The list prices are higher, but these are the prices we’ve observed the units are typically available for when they aren’t on sale. We’ve also observed that they are frequently available for special discounted prices, so shop around for a while before buying the unit you choose, and you’ll likely get a better deal.

I have two JuiceBox Pro40s load balancing on a 50amp breaker. Easy to set up and works great.

Thank you Phel for your support of JuiceBox!

For my Bolt EV, I had a NEMA 14-50 outlet installed on a 6×6 post at our driveway for my JuiceBox Pro 40. I opted for the JB “travel kit” which included a good quality, zippered bag and three adapters for different voltage and outlet configurations. Haven’t done any travelling with it yet.

Initially, I had trouble with the JB tripping the 50 amp breaker. I’d have to reset the breaker a couple of times per charging session. This was happening about every three sessions. JB support was great. Using their app, I just dialled the max charge rate from 40 amps down to 32 and the problem disappeared. The Bolt’s max charge rate is 32 amps anyway. That was about half a year back.

That is not too code

This is a well-written article which comes naturally for Tom Moloughney. It is very important to get this information out to newcomers so thanks, Tom. I concur that the Juicebox is the #1 pick in so many ways. There is a niche charger listed on IEVs site here that specializes in wind and solar applications offered by Myenergi. If you are looking for TOU, eMotorwerks may still be the #1 pick to work with renewables. If you are looking to install a solar array, the first thing to do is contact your utility and ask if they support “net metering”. Though net metering varies from state to state and from utility to utility, it generally states that the utility will buy your excess electricity for close to the rate that they sell to you. This is important to the long-term cost of your system. If they say no, don’t despair. An EV and the right charger can be your way around this. The Myenergi zappi is a smart charger that monitors your solar array and determines whether to give the power to your house or your EV. It will also decide on whether you want to charge during low sun… Read more »

The majority of new EV buyers seem to be getting Teslas. It’s disappointing that there’s no mention of the HPWC in this article. That’s a disservice to those new owners.

And, the majority of new Teslas are model 3.

Charging the long range model 3 with the supplied portable connector tops out at 32 Amps/240 Volts (7.7kW) requiring a 40 Amp breaker supplying a NEMA 14-50 outlet.

The wall connector, on the other hand, can go higher but not by much for the Model 3. For the long-range only, it tops out at 48 Amps/240 Volts (11.5kW) on a 60 Amp breaker.
For Mid and standard range model 3’s, the wall connector’s settable 32 Amp/7.7kW limit applies – same as the portable connector.

The wall connector is a bit more costly, and being hard-wired, arguably a considerably more onerous and pricey installation. It does have the advantage, though, of working in multiple Tesla Wall Connector situations (should you be so lucky).

With the portable connector for home charging it may be best to purchase a second one and leave it plugged in. 14-50 receptacles supposedly may be weakened by repeated use.

https://www.tesla.com/support/home-charging-installation/mobile-connector
https://www.tesla.com/support/home-charging-installation/wall-connector

Agreed. Tesla charger was $499 and delivers 48 amps.
Assuming you are a Tesla owner, I am not sure why anyone would pick any of these.

Very nice informative article. I have a model S and didn’t understand why anyone needed to buy a charging station until I read this article:
“However, most manufacturers only provide a basic Level 1, 120-volt charger, and offer as an option, a higher-powered level 2 unit for sale. In order to recharge their EV quicker, many owners choose to buy a 240-volt, Level 2 charging station and install it at their home. This goes for basically all electric vehicles other than Tesla. ”

I hope the other manufacturers start supplying the portable L2 chargers with the initial EV sale.

It’s a minor thing, but the new Tesla EVSE bags have a grippy surface (not velcro) that keeps it from sliding around in the trunk. Just good attention to detail.

Another point that the author hints heavily toward is getting a plug-in vs hardwired. Of course, your personal needs rule, but don’t discount the flexibility. My daughter is a few years out of college and drives an older Chevy Volt. Charging on the provided Level 1 EVSE fits her needs. It was a necessity for dad to add a Nema 14-50 outside plug ($50) to her service panel to plug in our mobile Tesla EVSE when we drive 276 miles to visit.

I’d be curious to see how well the OpenEVSE compares to what’s commercially available.

UL certification is useful if you don’t want to undermine you fire insurance. Does OpenEVSE provide a UL listed product? I suspect not.

I have seen similar comments to the effect that homeowners’ policies will not cover damages caused by using a non-UL listed product. Almost 40 years in the insurance field as an adjuster, I do not recall this ever being an issue. H/O policies are detailed contracts and your home is(typically with the most common policies)covered on an “All Risk” basis. There would need to be a written exclusion to damages such as this, and I have never seen one. Your company may be able to later terminate your policy(and even then there are strict regulations regarding that), but I do not know of any exclusions that would deny coverage to your home or garage in this circumstance. Having said this, I am not endorsing non-UL listed products, just trying to set the record straight.

jamcl3 is your EV UL certified?

OpenEVSE has recieved this question many times. Each time we reccomend the user contact their insurance carrier. Not once has a user reported their fire insurance would be undermined.

Build your own PC… have a 3D printer… Buy a generic phone charger? Most people have several non UL product in their homes.

Is there any good low power charger that I could use to charge my Volt overnight from a 110V outlet for around $100? I don’t need to charge every day, so I don’t really need anything of high quality.

If you have a second generation volt, (2016 and newer) the EVSE which came with the Volt is capable of 240 volt charging (I believe at 12 amps). You just need a cable adapter.
https://www.etsy.com/listing/656177603/level-2-upgrade-adapter-220-240v-for?ref=related-3

Edit: just realized I did not answer your question because you want a 110 volt charger.

We converted a dedicated 20 amp 110 circuit in our garage over to 240v and then use the stock gm charge cable for 12a 240v charging. Took charge time for the Volt from 10+ hrs down to about 5 hrs a night.

How do you “convert a dedicated 110 to 240V”? Didn’t you have to run wire from your electrical panel to the garage for a dedicated 240V plug?

So perhaps it is in the article but I didn’t see it clearly stated, if I have the Tesla Model 3 with the included 120 / 240 charger do I need any of these units? Could I simply have a 2:40 plug and be perfectly fine?

To reiterate Tom M: Yes.
But if you intend to carry the portable with you in the car; best to buy a second one to reduce wear and tear on the 14-50 outlet from constant plug/unplugging (or forgetting).

It’s worth knowing how your EVSE is manufactured/quality control. For that reason I favor the Clipper, Siemens, Webasto or Charge point. The j-box seems to be popular among hobbyists.

Tom, the Type 2 was standardized in the US for heavy trucks when SAE J3068 was published last spring. Volvo Trucks is deploying EV 18 wheelers in California starting next year and will incorporate the Type 2 connector, both for AC and DC. https://www.greentechmedia.com/articles/read/volvo-and-greenlots-dive-into-electric-truck-charging#gs.APXbR7U

So to be technical, you could say that “there’s one plug for North America that everybody besides Tesla uses” For Passenger Cars (also known as light duty or class one vehicles). California code of regulations section 1962.3 actually requires an adapter for J1772 up to class 3 (big pickup trucks) if the EV does not use a native J1772 charging inlet, if they want to work the ZEV credit market.

Clipper Creek makes a load- sharing level 2 charger as well

There are versions of the ClipperCreek station that shares power between two stations:
https://store.clippercreek.com/index.php?route=product/search&search=share2
Tesla’s optional wall station will share one circuit between 4 stations if I recall.

The Siemens versicharger has a known issue with the Tesla Model 3 where the Model 3 doesn’t keeps cutting off.

I don’t get it – last month we had a GLOWING review here of the high priced 30 ampere FLO unit. Now this month it doesn’t even make the top five. When some of us tongue-in-cheek poked fun at the high price the Sponsor FLO must have gotten all upset and all the comments were deleted from the “Commercial”.. At least this month, the selected units are somewhat lower priced. Oh by the way, the Old GM 3.3 kw limitation was not 16 amperes but 15. The part in the text where 16 amperes is stated to be 3.3 is actually 3.84 kw for most users. I’m not familiar with as many units as TOM M. is, but 5 I definitely would not buy are the: 1). Aerovironment (the round things, which may also be private labeled Nissan,Ford, or Chevy), and the 2). Schneider Electric units – either version 1 or 2. 3). , as well as those old (ON THE) BLINK things that caught fire in Berman’s house, as a for instance. 4). The BOSCH SPX junk almost never works in the field, even though they were usually sold for $999 – the one with the adjustable current limitation.… Read more »

I picked the Siemens unit because I didn’t see any benefit in buying the more expensive ones. It does what I want it to, and installation wasn’t too much of a hassle.

I’ve had GE Durastation for 34 months and have no complaints.

I’ve had a nice simple and basic GE Wattstation on a 50 amp circuit for 4 and a half years (5 years this July 2019.)

No advanced features, WIFI, etc, but reliably charges my Volt, and can charge at 30 amps, which should cover any vehicle I purchase in the immediate future.

If I was going to upgrade, it would be to a dual set of Juicebox Pros so I could share the circuit with two vehicles.

Like others have said, Siemens VersiCharge is a great option for the price. 30A, no smarts, low price. what it lacks in smarts is made up in my Bolt’s onboard charging settings (utility rate, departure time, etc). The myChevrlet app gives the owner control over charging without having to pay extra for an EVSE. That said, a lot of interested EVSE buyers get hung up on 30A, 32A, 40A and assume the higher Amp units are essential to keeping them on the road. This article misses this aspect, including some guidance would be useful for some buyers. So, to compare, assume a 60kWh battery pack, 0-100% SOC: 30A – 7.2kW/h or 8.3 hours 32A – 7.5kW/h or 8.0 hours (Bolt maxes out at this rate) 32A – 7.7kW/h or 7.8 hours 40A – 9.6kW/h or 6.25 hours The Chevy Bolt takes up to 7.5kW/h on AC, so a 32A EVSE offers more power than the car can utilize. Since most of us will plug in with 40-50% SOC, cut the times in half. Even if your car could fully use 40A service, the 6.25hr full time to charge would make little difference in overnight scenarios where you have 12 hours… Read more »

The Khons charging solutions (stationary and mobile) are a very good choice for any EV driver. You can change the charging power from 8 Amp to 32 Amp, and from single phase to three phase. I’m not from Khons, I’m just one of their happy customers. Khons is a native Chinese company.

As an electrician, I would argue that hard wiring an EVSE is much cheaper and simpler than installing a 50a outlet. In particular, if you are installing the charging unit outside, a weather proof 50a receptacle isn’t cheap. Furthermore, having that extra point of connection at the receptacle is a potential weak point as these loads are continuous and will heat up. Over time this could fail and then you would have to replace the plug and receptacle. On the other hand, a hard wired installation only requires a box and a blank plate, simple. The splices inside the box are a lot more reliable as well.

A point that you’ve spotted that they have missed here, is that most units are acceptable for outdoor use ONLY when hard wired. The cord-and-plug version is labeled ‘indoor only’.

Bill: How about “outdoors” but under a roof, such as a covered patio? Not really exposed to rain/snow but yes to extremes of weather.

Sure Lou most of this is common sense… Once you buy the unit you can do what you want. Just be careful with Blowing Snow. Sometimes with the occasional use cords I’ve had good success with putting the things in plastic bags since there isn’t much heat generated.

Just get the Tesla wall connector. It’s priced very well. You can charger other cars with the adapter and it can deliver upto 80amp on a 100am breaker.

Now all you need to do is find a used Tesla that can take 80 amperes. No new one can take more than 48 amperes, no matter how much you spend for it. Which is rather uncanny since my Roadster with zero options did 70 amperes.

You say the JuiceBox “checks all the boxes”, yet neither it has no holster or cord management to speak of; that’s one of the things I love about my ChargePoint.

Typo: Level 1 chargers will deliver between 3 and 5 miles of range to a typical electric car. Should be “per hour of charging” in there somewhere.

Very informative. Look forward to the 2nd article as well. Possibly a silly question: I see only two cords coming out of the Juice Box: one to plug in to the 240 outlet and the other to charge the car. I am leaning towards purchasing a second EV, you mentioned load balancing which is exactly what i need. but where is the cord for the second EV?

Well written article! We also like the new PowerCharge Energy Series as a solid choice and is very competitively priced, Available in ‘smart’ or ‘dumb’ versions on Amazon or at evCHARGEsolutions.com

$500-Tesla Wall Connector (100 Amp) blows these out of the water. If someone can design the Tesla-to-standard converter, no one would buy these chargers.

Partial Correction Mr. Truong: TWC’s (they prefer it to be called a HPWC, as opposed to the Clipper-Creek HPC sold with the TSL-01 connector for the original Roadster) can run up to 80 amperes, although it is increasingly difficult to find a Tesla that can use it, since Tesla now recommends a 60 ampere overcurrent device to be used for their current vehicles (48 amperes maximum no matter what you buy).

Some Bolt owners have bought adapters since $500 ain’t much coin, and the adapter price still makes the unit within the ball park of usability. Especially compared to the overpriced stuff.

One thing not mentioned in the reviews: Can they all be dialed down as to how much current they draw on the input side. My house is wired with 30A 220. TO go above that, I would have to do major electrical work. If I dial down to 30A input, what output will I get as the article doesn’t mention efficiency. 24A, 26A, 28A????
Thanks, Ken

Ken – the so called ‘chargers’ are all 100% efficient since they are all just like light switches.. They are just a smart switch.

Editor: You mean you erase any comments on the informercials now?

We bought a Bolt last year & installed a Clipper Creek unit at our ground mount solar panels (also where our service comes in). Last summer when the temps here got above 100 F there was a problem with the unit. (After resetting the breaker, it worked fine.) I called Clipper Creek & did some onsite diagnostic work. They offered to send a replacement unit that day. Since I was going to be driving near by in a few days, I elected to take them the unit & pick up the replacement. Their service was top notch. BTW–I don’t get to drive the Bolt much, the wife has it most of the time. I’m waiting on the Rivian!

Regarding the talk here about UL approval…I have a JuiceBox Pro that I bought 2.5 years ago, which was before it had UL approval. Any safety issues with that? It didn’t have the outside casing then–really just a utilitarian metal box–but the functionality doesn’t seem to have changed in the past few years.

So, could the author supply some idea of what we should buy in Europe or Australasia where we have 220/240 volt supply?
Personally I have 3-phase supply in France, so another set of variables.
My Model 3 in France is slated for delivery in the spring, so need to think about charger installation soon.

Wanted to find out if all leve 1 chargers are the same or if some are better than others. My Honda Clarity came with a level 1 charger and it takes 12 hours for 45 miles (roughly 3-4 mi/hr). I have seen some claims online of level 1 evse’s that say that they are “twice as fast” as the OEM’s that came free with the car. Can that be true? Why would a car manufacturer give their clients an evse that is half as fast as it could be?
