Tesla Mobile Connector Versus Wall Connector – Pros & Cons

AUG 23 2018 BY STEVEN LOVEDAY 8

Should you stick with Tesla’s included Mobile Connector or opt for the Wall Connector?

As more and more people are beginning to buy electric cars, there are a ton of questions about charging. The average Joe or Jane could be very interested in going electric, but not have a clue when it comes to the technology. This is especially true with hundreds of thousands of new Tesla Model 3 owners who will take delivery of their vehicles in the not-so-distant future.

Every Tesla vehicle comes standard with a Mobile Connector. What are its pros and cons? You can purchase a Wall Connector from Tesla ($500) as well. Why would one choose to do so? Is it worth it? YouTube channel, LivingElectric, sheds some light on these questions. It’s important to note that this review was conducted in the U.S. and the information contained may vary in other countries.

Check out the short video to learn about the pros and cons of each option. Which do you use? Do you agree with LivingElectric’s analysis and opinions? Share your experience and pros and cons in the comment section below.

I just got a Model-3 as well and I was blown away by how nice the EVSE is that comes with the car. It’s soooo much better than any other EVSE I’ve ever seen come standard with any vehicle. One of the first things I thought to myself was that, if I didn’t have two 32-amp EVSEs already installed on the wall (which I also need to use for my other non-tesla cars), then this would be the only charging option i would need. Let’s face it, after years of owning EVs I think I’ve used a mobile EVSE away from home maybe twice. And in both cases I knew I would be doing that ahead of time. And those vehicles had about a quarter of the range of my new Model 3. So, there’s really no reason to need to fret about bringing the charge cable with me every day. This “portable” EVSE could serve as my one and only home charger. I wish all EVs came with such a nice portable charger.

I agree with David, you really don’t need to bring it with every day. I have had my Tesla for 5+ years and I have yet to use the mobile charger on the go. The mileage is so high it isn’t needed or usually there is a Supercharger near by or on route.

I hold my mobile charger to the wall for a cleaner install and puts less stress on the wall plugin using this holder https://bastens.com/products/tesla-mobile-charger-holder the wall connector but can not permanently mounted so the mobile charger can be taken on the go.

I would like to mention there is another version of mobile charger that is not mentioned in the video. There is a charger for the Model S/X that will charger at a 40 Amp rate (as apposed to the 32 Amp Gen 2 or 48 Amp Wall connector) … I understand that this video probably was intended for Model 3 owners but I wanted to through that out there for Model S/X prospective buyers.

In North America, the only charging cord provided with ANY Tesla is the far safer 32 ampere model just described. They’ve basically discontinued the 40 amp version – a wise decision.

I would like to correct Bill, the 40 Amp mobile charger version is still sold from Tesla here https://shop.tesla.com/us/en/product/vehicle-accessories/model-s_x-corded-mobile-connector.html … it doesn’t say on the website but you can confirm with Tesla (as we did) that this model charges at 40 Amps. Again note this is listed for the Model S/X only, I don’t know why it cannot be used on a Model 3.

My husband reminded me (Electrical Engineer) that these are *NOT* chargers. They are safety devices. The reason why they limit the one Gen 2 to 32 Amps is because it has interchangeable ends (one linked does not offer interchangeable ends). So I guess you could say it was a ‘wise decision’ to limit the mobile connector with the interchangeable ends? Other than that there is no reason to not use a mobile charger every day to its fullest capability. We have been using our 40 Amp version for 5+ years. The mobile chargers are design to use the general Engineers design rule of 80% use of the designed hardware which leaves plenty of room for high ambient temp situations, which he also confirmed with Tesla.

Sorry Val, I don’t accept the correction since I haven’t mis-stated anything. Yes, the 40 amp mc is still available for sale, just as the roadster 40 amp UMC for $1500 was available long after they stopped making roadsters. I’m glad at least your husband realizes they are not chargers. The 40 amp MC’s were someone dangerous in that the switching relay was only rated at 30 amperes, and the attachment plug with its pin sized male attachment did not mean NEMA standards of current density. Of course it couldn’t be UL listed.. You are behind the times Val. The REASON they offered a ‘non-changeable’ 14-50 plug is because that eliminated a bad heating problem they had with the changeable ones. When homes started catching fire because of the original units, articles here or at PLUGINCARS stated the problem was 1). The electrician who wired the outlet. 2). The inspector who inspected it. 3). Of course, Tesla’s response was the car never overheated. Of course not. The problem was with the 14-50P, which Tesla included WITH the car. Their solution was 3 pronged: A). Lower the current if the voltage dipped – first to 32 then to 24 amperes. B).… Read more »

“… The 40 amp MC’s were someone dangerous in that the switching relay was only rated at 30 amperes, and the attachment plug with its pin sized male attachment did not mean NEMA standards of current density. Of course it couldn’t be UL listed.. “. substitute ‘somewhat’ and ‘meet’.

‘…not being able to used with the Model 3.’ substitute ‘not being able to be used with the Model 3.’

What Morons – this is obviously a spell check note to the editor of an existing comment. And it gets totally voted down as if someone is against Spelling Error Corrections. Keep it up guys!!! hehe. Getting hard to take this place seriously if there is no one left with any reading comprehension skills.

Pretty complete video – only thing I’d say is that receptacle wear with the included charging cord is easily taken care of by disconnecting the cord at the ‘evse’, and leaving the cord stub plugged in all the time. Of course, that is only possible if you are only using the cord in one location, or have an additional cord set for a second location. Alternatively, you could just leave the cord plugged in all the time and if desired, switch the receptacle on and off.

I’m not aware of any safety issues with the new cord as it is far safer than the original since:

1). Being supplied with all Teslas currently, it is of lower current (32 vs 40 amperes).

2). The ‘adapter’ is no longer a very undersized cap on the PLUG, where overheating can easily get in the household wiring, but is at least several inches away – keeping the household wiring cooler.

(This is far different than the FORD or CHEVY charging issues, since with those companies the fault never was with the charging cords themselves).
