That Coleman cable is what I used for mine. Works great...only slight downside is my adapter is pretty short, but I also used a bigger 14-50 end...

@Gavinmcc - how well does that 14-50 R plug seal to the cable going in to it? Was it difficult to remove the neutral pin from the plug? Mine was a dual purpose 14-30R / 14-50R connector, so the neutral pin was designed to be swapped out. Wondering if yours was molded or glued in, or did it pop right out?

After going to Home Depot and striking out finding the right stuff to make it myself, decided to get the adapter cord the OP posted. Thank you for the info! Love this forum.

Got the adapter cord yesterday and it works like a charm. Really nice quality, super thick gauge wire, and all molded together with no gaps. I'm using it in an outlet originally installed for welding equipment out in my workshop. Nice to have L2 charging available now as an option! Looking forward to being able to preheat the cabin in the winter without sacrificing any battery.

It takes real L2 to do that. Understand that you will be getting, at best, 240V x 12 A = 2.88 kW charging, and preheating your cabin can use much more...up to 7.5 kW. So you most likely will be using some battery, just not as much

Touche. Amend to "Looking forward to being able to preheat the cabin in the winter without sacrificing as much battery."

I'm not using the stock EVSE though... I'm using a Duosida L2 16A unit. Is there an easy way for me to monitor the charging rate? What is normally a 10 hour charge on 110 took me less than 3 last night.

OK. The Bolt will allow 16 amp charging with 240 volt, so you should see 3.8 kW charging. I am confused. It looks your EVSE is sold with a NEMA 6-20 plug. Is that what yours has? If so, how does the 10-30 Plug Male to Household 5-15 adapter held you?

You can see your energy use within a half kW on the DIC, if you power up the car while charging. If you turn off the lights, fan/climate controls,and radio, you are pretty much left with charging power in.

Looks like it's sold in a bunch of configurations. Mine is just the household 5-15 3-prong plug, which is why I needed the NEMA 10-30 to 5-15 adapter wire the OP listed.

Thanks for the discussion as well. Really appreciate it. I'll try that trick to turn it on and monitor the DIC. I didn't realize it would display incoming power.... so it will look similar to what I see while moving and using the regen?

Reporting back that my new $50 adapter works great btw. Just received it a few days ago. I love that there are cheaper solutions than spending 1k + on an EVSE solution. Thanks everyone for your input.

The Tesla mobile gen 2 EVSE will do 240V @ 32A and costs $275.

You do have to buy a Tesla-to-J1772 adapter to use it, but we bought one of those anyway, so we could charge at a Tesla station.

This is best price I can find to adapt a NEMA 14-50 to a 5-15 for use with the Bolt OEM EVSE. $30 to convert 14-50P to 6-20R then a $8 adapter to convert the 6-20P to 5-15R. No wire cutting.

$20-26 if you want to mess with splicing...

Just got mine delivered. Now waiting to add me NEMA 14-50 receptacle then I am good to go. Although, after testing the OEM EVSE and seeing it did not trip my breakers nor GFI, I've been good to go from day 1.

My reason for getting this configuration is:
1. No wire cutting/splicing. Nothing to screw up.
2. With the NEMA 14-50P to 6-20R, I am also ready to use any 6-20P L2 16A EVSE.

My comments:
BloomGrow adapter - looks nice and durable. This will go on my EOM EVSE.
NEMA 14-50P to 6-20R - stamp on cable shows (UL) STW 3/G 10AWG 105 deg C 600V VW-1 E313667. This will stay with the receptacle on the wall.

I took the really short cut for 240v charging at home. I just landed two phases on a regular duplex outlet.
Now, of course, this is terrible and you should never ever do this. Ever. Period. You will shoot your eye out kid. Seriously.
I wired up a 6ga cord at work on a 50A circuit in preparation for a 32A charger and found a 14-50 cord cap on Amazon for $4 free shipping. It showed up and is legit!

I'd be disassembling and carefully examining that "cord cap" from Amazon. 12A constant current at 240V is something you don't want to compromise on. For such mission- and safety-critical applications, I always stick with quality stuff that I see good, licensed electricians use on their own homes. My adapters are made with Hubbell components, tightened with a torque wrench and re-checked after some usage. The cable material is one gauge bigger than "necessary", too.

You also might want to consider replacing the 5-15R with a new 5-20R commercial grade. This is what I did with the duplex outlets that I'm running my "stock" EVSE with. But...instead of wiring within the j-box, I put in a dual duplex outlet j-box and ran each phase to its own duplex receptacle in that box. (Technically, you should then gang the two breakers together at the e-panel to be NEC-compliant. I did.) I then made a y-connector adapter out of two 5-15P into a single L6-20R to pick up the two phases for the 240V. This way, the duplex outlets can still be used for anything else in the 120V realm, and would be safe. You could do the same, but sub a 14-50R for the L6-20R.

No-way no-how would I do what you did with the 5-15R at 240V, but each of us has to evaluate our own "pucker-factor". I'd end up royally constipated, but then again, that would allow others to truthfully claim I was full of sh*t.:poop:
