eMotorWerks Releases First WiFi-Connected 5 kW Portable Charging Cord, And Also A 18 kW L2 EVSE


Charging equipment supply company eMotorWerks sent a note informing us of a couple new charging products the company has just released.

One of which is something new to the market – the “JuiceCord“, which is a portable L2 unit capable of dispensing 5 kW (20A) of power while utilizing the company’s JuiceNet­enabled features – which basically means via your mobile device you can control the ToU (time of use) charge for your plug-in vehicle when connected.  (full specs below)

Just as important than all that, is the price, which is very competitive at $449 – and it’s available worldwide, with a full set of adapters available to suit the need.

New High Power Offering - JuiceBox Pro75 - 18 kW

New High Power Offering – JuiceBox Pro75 – 18 kW

Separately for those who need A LOT of power, or merely want to “future proof” their EVSE for the next plug-in that graces the driveway, eMotorWerks has introduced the JuiceBox Pro 75, which “allows drivers to charge any current EV on the market at its full level 2 charging rate.”

The JuiceBox Pro 75 currently retails for $899, and offers 18kW (75A) of power.

Valery Miftakhov (founder of eMotorWerks) on his company’s new offering:

“JuiceCord is a special new product that brings the benefits of WiFi connectivity, portability, and power to our customers.

We worked hard to keep it affordable while also having it work with our rewards program that pays drivers to charge..and our JuiceBox Pro 75 is unique to the industry, offering highest level 2 power available, future­proof ease of mind, and all the benefits of smart­grid charging.”

    I really don’t understand why it has to be so expensive, its just 2 cables 3 plugs, one single MOSFET with a bit of micro controller 3 sensors and a connection to the internet. Thats about $20…

    1. Mike says:

      I’m sure if they were building millions of them, they would be cheaper but the cheap EVSE above carries 20A. Just the wire for that is going to cost more than $20.

      1. Djoni says:

        A lot more!
        And they have to pay some royalties on the J1772 as far as I know.

    2. Lou says:

      $449 is indeed a lot for that product, but that’s largely (entirely?) a side effect of the still-youthful EV market.

      Once EVs really take off, something we’ll see in the next couple of years, I expect the prices of such gear will drop and the availability will soar until you can buy them off the shelf at Pep Boys and Home Depot for around $100 to $150.

      The last time I looked the L1 EVSE from Nissan for my Leaf was over $700(!!!). Talk about electric highway robbery…

      1. Clarence says:

        Home Depot had two different EVSE on the shelf in my store.
        Not $150, but surprising.

    3. telveer says:

      EVSEs are expensive in general, not because of parts but because of the small market. As the market increases, prices will come down due to economies of scale.

      I think a 220V 20A (5kw max) 20ft “Made In USA” WiFi enabled portable outdoor capable L1/L2 EVSE with 3 year (residential use) warranty for $450 (with free shipping) is a compelling buy for someone looking to get a new L2 Smart EVSE with a built-in charger of 5kw or less.

  2. Carticle Pannon says:

    I can’t believe you guys didn’t focus on the huge advantage of the JB Pro 75 unit 😉

    — quote —
    “If you have more than one EV, you can set up your two (or more) JuiceBox Pro units to share one electrical line! Say, you have only 80A capacity in your panel but have two Teslas (lucky you!). You can program your JuiceBox Pro units to never exceed 80A combined draw. If only one car is charging, it gets full 75A of current. When the second car shows up, the current gets shared 40A / 40A between the two. When one of the cars finishes charging, the remaining car ramps back to 75A.”
    — end quote —

    This is a feature Tesla just started offering with their new HPWC (which looks amazing, and they dropped the price as well), but the HPWC can’t charge J1772 vehicles, and doesn’t have Wi-Fi.

    Until a few days ago, only a few manufacturers offered this feature in their very expensive commercial stations, so $900, what I paid for my AeroVironment 30A unit just 3 years ago, is a hell of a deal.

    1. Dave R says:

      Can you also share smaller circuits? Say a 40A circuit and limit accordingly?

      1. Carticle Pannon says:

        Looks like it:

        “In the package, you will receive:

        Your very own JuiceBox Pro 75 with the following cables already wired in:
        An un-terminated input cable (AWG6, ready to be hardwired by an electrician or you can attach a plug of your choice if you would like to use the Pro75 at less than 50A output)

        It looks like their other Pro units support it as well (they refer to as Circuit Balancing), but are more expensive.

    2. wraithnot says:

      Thanks for the information- I already own the lower power version of the juicebox pro and I didn’t realize it had this capability. We have two EVs (a Tesla model S and BMW i3) and a single 50 amp circuit in the garage. Trying to charge them both exclusively during off-peak hours with a single plug can get a bit tricky since off-peak hours are 11 pm to 7 am. A splitter on our NEMA 14-50 outlet and a second juicebox pro programmed to share the circuit would do the trick.

    Anyone know any outdoor charging boxes that protect the cord from snow and ice?

    1. Bill Howland says:

      If I understand the text, then both units may be used in cold weather.

      The cord is a bit pricey since you can get an ‘ugly durastation’ for $399 with 50% more current (optionable from 12-30), but the 75 amp juicebox seems rather fun if it can work reliably day in and day out at that current.

      Now that new teslas are only 72 amps, it looks big enough. $900 isn’t so bad and the multiple current limit feature some may find handy if they have multiple teslas.

      Someone could say the official tesla products are cheaper, but these look to the future when their are either larger EV’s (Lincoln Navigator sized- with quick 75 amp chargers), or just optional faster chargers such as may eventually appear on Bolt-like products, with industry standard (J1772) connectors for NA.

  4. Foo says:

    They should make an orange one, and call it OrangeJuice.

    1. Dorian says:

      Man, that’s a good idea

  5. Jamcl3 says:

    Not UL listed (yet), I wonder if they will go for listing? It is expensive but worth it not to void your home owner’s insurance coverage for fire loss.

    1. Bill Howland says:

      Good point. My 5 year old Schneider Electric EVLink (30 amp) initially was rather a crappy design that overheated when running 30 amps for 9 hours, until I changed the lugs around in the unit to make everything run cool.

      And this thing that overheated had a ‘UL Recognized’ logo on it. But then UL is a much crappier organization than it was decades ago.

      But it does tell you something about equipment that can’t get even a UL Recognized stamp. Of course, anyone who can’t get one will probably say, its “pending”, hehe.

  6. Bill Howland says:

    I wish manufacturers in general took charging more seriously.

    Car charging docking equipment is so much simpler than gasoline filling station equipment.

    So you’d be excused if you thought you’d have much less trouble at an EV ‘filling station’ than a gasoline one.

    Gasoline ones almost always work, and there are several ‘ports’ nearby if there is the rare one that doesn’t.

    As a for instance, I just tried calling ChargePoint to tell them about a defective station (the same station has been defective more than once – first for not accepting the RFID card, and then now, for refusing to unlock the cord (a SUPERDUMB idea in the first place), when the unit thinks it has unlocked it.

    Of course, the modern chargepoints with the video screen models NEVER seem to easily release the cord, and they’re considered WORKING. heheh.

    The guy at the other end wouldn’t take the trouble report unless I gave him my life history, so I just told him this is a joke, and just forget it – I’ll let someone else call it in, if anyone cares. You’d think the business owner would since they have to pay CP a subscription fee every month (no wonder so few businesses have put these things in, in my area).

    I have yet to even see a ccs or chademo charger, and don’t have a tesla anymore, so I have yet to undergo the frustration of any of the perenially defective things, which others here legitimately gripe about.

    And of course, you wouldn’t want a chintzy wallbox to burn your house down.

    I guess I don’t understand ChargePoint’s business model, other than getting plenty of free money (to them) from gov’t subsidies. If they had to do it without them I think they’d fare about as well as those bankrupt (ON THE) Blink things.
