Will the evse still be topped out at 12 amps?
Common 120V receptacles are built with the idea that people will be plugging in and unplugging things all the time, and are built for this use case. A normal 240V receptacle is built with the idea that someone will plug in their stove / water heater / cloths dryer once, and leave it plugged in until it needs to be replaced... not built for repeated plug / unplug cycles.What do you mean by "overcycle"? I have a 14-50 adapter for my oem Bolt evse that I use occasionally on my 240 volt line but mostly I use without the adapter on the 120 volt outlet. I should leave the adapter plugged into the 240 volt and just unplug the evse from the adapter why?
Where did you find this adapter? Looking for something similar, but can’t find one.

Perfect, thanks! I was searching for 6-20R, didn't notice that it's a 6-15R.
Thanks for the correction. Yep, it's a 6-15P
Note that this a 6-15 plug with two horizontal blades. So make sure that the adapter from the 14-50P ends in a 6-15/20R that has two horizontal blade sockets.

I just picked up my Premier today. I do have NEMA 14-50 outlet with a 50A breaker installed in my garage.That's correct. I've been running mine on 240 since 2017. 12x240 is nearly 3kW. So you almost get a bar an hour. I typically charge when the car hits 7 bars and set the car to stop at 18 bars. So takes about 12 hours to charge with the 12 amps on 240. Plug in before 8:00 PM, and the car will be charged by 8:00AM. Never bothered to get an aftermarket EVSE because the one that came with the car meets my needs just fine.
I did this recently for my NEMA 10-50 outlet. It certainly is not “to code”, but the OEM EVSE is included with Volts and Bolts in countries with 230-240v standard home circuits and comes with appropriate plugs for those countries.I just picked up my Premier today.

Is it really safe to plug in the stock portable charger that clearly states 120V on it, into 240V NEMA 14-50? Dealer knew nothing about it and I certainly don't want to burn the supplied charger. Thank you!
Welcome to the forum. It's a big disappointment that GM doesn't provide anything official. Technically they can't with the standard plug that they chose. So the unit only states 120V on it. I still closed my eyes when I plugged it in. Initially I wanted to change out the cord and took the unit apart to do so. The cord is soldered to the printed circuit board. But clearly on the circuit board it was labeled L1 and L2. With suggestions from this forum, I aborted my attempt to replace the cord and just made an adapter with the correct connections. No modification to the EVSE was required. Just an adapter. I've actually got two of them and have them both plugged into 240V.Is it really safe to plug in the stock portable charger that clearly states 120V on it, into 240V NEMA 14-50?

Many thanks! I wish they simply labeled the OEM EVSE using the usual "Input 120/240V, output..." whatever it is.I did this recently for my NEMA 10-50 outlet.

It is not unlike computers which sense 120 or 240 supply and adjust. At work, we have hundreds of servers in our data center which used 120v until we moved to a new location. We chose 240v power for all of them because they generate less heat on 240v.
All you are doing is putting 120v on the hot and neutral pins. The EVSE still only pulls 12A but the Bolt receives 2x 120v 12A feeds so double the kW.
Like a 100 watt bulb on a 1800 watt 15A circuit, the appliance pulls only what it is designed to pull. It is never an issue putting devices with lower loads an higher Amp circuits. The only risk is if the appliance isn’t capable of handling the higher voltage. The EVSE is designed to handle 240v.
Like any power cord, care must be taken to ensure solid connections. The RV world uses adapters all the time.

No. You still can't plug the OEM EVSE into that.Thank you very much! I did buy a welder's adapter 50CM(1.5FT) Nema 14-50P to 6-50R Heavy Duty # AWG8 STW 50 Amp Plug to 50 Amp (Welder) Socket Adapter Cable, Adapter Cord 50A Dryer 14-50P to Welder 6-50R 50A, Welding Adapter 6-50, 250V - - Amazon.com
It looks like it should do, right?
I wish they did as well. Then I would feel better about it.Many thanks! I wish they simply labeled the OEM EVSE using the usual "Input 120/240V, output..." whatever it is.
Sorry if this is redundant, but is it impossible to use the OEM EVSE at NEMA 14-50 and achieve 30A charge rate? Is it still limited to 2x12A? What charge rate in miles per charge hour will it result? Thank you all for your patience!
Despite the similarity, that is not a 120v outlet on that adapter. It's a Nema 6-50r, which is similar but much larger than a household 5-15r.Thank you very much!

As XJ12 mentioned, if you don't believe it, take the EVSE apart and look at the circuit board. It is designed to run on 120v or 240v. I took mine apart, not because I didn't believe it, but because I'm goofy and just like to see what's inside. Sure enough, Clipper Creek guts and designed for either voltage. Been running it at 240v for months.Is it really safe to plug in the stock portable charger that clearly states 120V on it, into 240V NEMA 14-50?
No, the OEM cord is limited to 12A. So, even if you could plug in to a 100A circuit, you would still only get 12A. But, because it is 240V instead if 120, you get 2x kW charging speeds.Many thanks! I wish they simply labeled the OEM EVSE using the usual "Input 120/240V, output..." whatever it is.
