PowerShare Mobile Connector (Gen 3) -- Discussion

[Cybergirl]

Figured it was availability, but wanted to check. It's in stock, behind a pull down on the adapter page.

I missed that. Thanks.

Thanks for starting this thread. I've charged my CT with a Tesla UWC without issue and a Gen 2 mobile charger plugged into a NEMA 14-50 at our other house. I was trying to figure out the differences between the mobile charger included with the truck and the Gen2 mobile charger, of which I have an extra, and the only thing I've noticed is the label for the box for the mobile charger that came with the truck has a V2L indication on it. Does that mean the Gen3 mobile charger can supply power out? And under what circumstance would this be useful as opposed to using the bed outlets for power-out?

Actually, this isn't necessarily true. Many of the other EV chargers (such as the GM one) require an actual ground connection or they will not function. There can be no such ground connection on the truck, because it obviously isn't connected to the earth.

So you need a charger that can work from a portable generator, which similarly will not have a real ground connection.

I tried this with my friend's GM charger and his Volt. His charger would not energize from the truck at all. It would just throw errors

I'm not sure it was a "real" ground issue. What would the adapter use as a reference to test?

If the EVSE checks ground to neutral, that could be an issue with a generator that lacks the bonding jumper.

Exactly. Eventually, Tesla will have outlet adapters for your drvices instead of plug adapters to charge with. Advantage is powering devices with vault closed, better weather protection, and possibly it will increase the total output (if the 32A allows a full 48A combined). Or just a handy 20 foot extension cord. 40 if you go PSMC to MC ...

well, sure, that's my point. The neutral being connected to ground, and the ground not being a separate connection, is the issue.

The point remains, the adapters may not just work on cybertruck. And you may not easily be able to find out in advance which ones will or won't work.

Neutral is supposed to he bonded to ground though. Normally at the service entrance for buildings.

Whichever thing is supposed to happen, the opposite seems to be true in the truck. I'm very well versed in DC electronics and troubleshooting, but not as well versed in AC power stuff. The extent of the error I got was:

"Problem external to Charge Cord, check wall receptacle and vehicle". and we know it wasn't a vehicle problem, because the issue started before plugging into my friend's vehicle. Plug into a real wall outlet, works fine. Plug into cybertruck, it doesn't.

We did all kinds of troubleshooting, and the bottom line was the GM EVSE would absolutely not work in the truck, while the tesla mobile charger would.


EDIT: In fact, I did test the cybertuck outlet with a multimeter at the time for continuity between neutral and ground (this was 2 months ago so I forgot what I was looking for). I just did it again now to be sure, and there is no connection between neutral and ground.

Ha, you edit occurred as I was checking.
Just checked and neutral is not bonded to ground on Cybertruck. Also, the pair of 5-20s in the bed are fed from the same phase.

Since my house is for sale I'm not going to spend $2000-$4000 for the wall mounted solution/powershare so this is the solution I'm using for now.

1 Nema 14-30 splitter connected to my dryer plug in laundry room:

1 25' Nema 14-30 extension cord:

1 Tesla Gen II 14-30 adaptor (as seen in other post)

https://a.co/d/hCqmv0k

1 hole in laundry room wall... ?

Entire setup was only $200 and charges at 24 amp, 12/13 mi/hr, 236v

I am certain the wiring is correct from where I extended it over. I am well versed in home wiring and circuits <100A, fused disconnects, blah blah....but will have to pull the cover off the splice box and make sure. Since the 14-30x(4) 110v adapter worked, I was certain it was a hardware (computer/similar) issue, but the 240V showing in the App had me puzzled to begin with-figured it was something to do with the juice that was behind the (4) 110v adapter, but will trace the circuit back and verify everything.

I bought a short-sale in 2015, and came to find most everything was an Uncle Bob hack job. I have corrected 95% of the issues I have discovered over the years, but I pulled the unused 40A water heater circuit I mentioned in OP out from the wall yesterday to find 10ga cable, so that in itself leads me to believe the 30A I am using for charging may have some issues as well.

Appreciate all the input and glad others (seem to) find it helpful as well.

And that's pretty much the way that it is supposed to be. Both the neutral and the ground are ALWAYS connected together in your house. The only difference is that they are only connected at the distribution panel.

That's a perfect solution that will trip breakers and cause issues. Y splitters, extension and extension cords are problematic.

Was power engaged?

Was power engaged?

I tested it both ways just to be sure I didn't miss a troubleshooting step, and it was the same. No continuity between ground and neutral.

Haven’t had any yet and the only option I have since the closest supercharger is an hour away. The dryer is the only device connected to the same breaker and I don’t use it if I’m charging.

My problem is using 14-50 adaptor come with the truck only gives me 6A on a 50A outlet. Use my friend’s gen 2 MC with gen 2 14-50 adaptor can go up to 32A, but as soon as I used my own 14-50 adapter on his gen 2 MC, the charge back to 6A again. Then we tested use my gen 3 MC with his gen 2 14-50 adapter, it works up to 32A again. Is there something wrong on the adapter itself? Very strange.
