A friend needed to support his son who would be running a 'very cold' marathon on Sunday while rucking a 30 pound pack. The outside temps will be around 15F-20F the whole time. The location of the race is nowhere close to any L2 chargers, but he's not worried about driving distance to or from the race - it is 50 miles away from his house. He says he will be sitting in his ruck with his laptop and watching his live track+Garmin inReach data for the duration of the race (about 4 hours). He thought about taking his Honda EB2800i gasoline powered generator, if he can use the level 1 EVSE attached to the generator and keep the truck running with full heat + power - without really consuming much of the truck's main battery? He feels it's super dorky to have a gas generator running while attached to a Rivian in the woods, just so he can stay warm, but don't know if it would work ok this way and 'preserve' the main battery so he doesn't need to worry about driving range when we wants to head home. He talked to me about it and I told him the simple answer is NO. I tested this theory the other night when I was plugged into a 5.9kW charger. To maintain the interior amenities (interior and exterior lights, radio, heater, seat heaters), it took almost all of the charge. I charged for 15 minutes, it delivered 1.6kW, and the truck consumed 1.4kW, delivering only 0.2kW to the truck battery. Told him he would be using a laptop at another 200ish watts. The little trickle charger charges at 1.4kW on a good day, 1.2kW is normal for me. You can slow the bleed, but you cant stop it. My advise to him was for him to charge it up to 100% at home, and roll the dice is what I would do.

After finally getting his supercharger adapter from Rivian, Josh decided to put this together and it wasn't bad at all as I'm actually impressed.

He barely stuffs the center console with anything aside from a few spare charging cables and some basic paperwork so it was pretty much always just a gaping cavern.

So he figured this was a better use for it and the divider still allows cables and such to sit down there no problem.

He debated making a hinged cover but then realized that would just encourage adding a bunch of stuff on top. Which would then need to be taken out to flip the lid and pull an adapter out so he just left it open.

He angled the supercharger adapter to gain back a little extra space on the divider and to allow enough space to get a finger in there to pop the latch to pull it out.

When we spoke about it, he said he might be making a few tweaks but, he shared with me the model for printing if there is any interest. Here are photos of the print so you can see how good they look.
