How is level 1 charging? 3 to 4 miles per hour?

[blzabub]

Question for anyone with an R2 that has charged it on Level 1 (mobile connector, 120v/12amp), what kind of rates are you getting? I'm hoping to get Tesla Model Y equivalent of 5 miles per hour on level 1. Thanks in advance!

Level 1 is generally considered to be 120V, 12A (80% of a 15A circuit.) That's 1.4kW. It doesn't matter what vehicle, you're going to be sending 1.4kW from your wall to the vehicle.

Take the vehicle efficiency of ~3.5 mi/kWh for the R2 with road all-season tires, multiply that by 1.4kW, and you get ~5 miles per hour. Less with off-road all-terrains.

Really what you're asking is "is the R2 as efficient as Model Y?" - according to the EPA, yes. According to the few "mixed driving" customer reports, yes. According to "high speed highway" tests, no. (The boxier shape makes more of a difference at highway speeds.)

You're not factoring in overhead at all, which is probably a few hundred watts, or more if cold. Less relevant when charging at higher L2 or DCFC, but pretty significant on L1. Probably about 3-3.5 mph on 1.4kW.

In another thread we deduced that the overhead is anywhere from 400-1000W, so you're only putting about 0.4-1.0kW into the battery. Simply stepping up to a 5-20 (20A) plug can nearly double that because the overhead stays constant. Converting a 5-15 outlet to 5-20 is pretty easy (assuming a dedicated circuit) by using the neutral as the second hot.
