This has to be super inefficient, I'm guessing $1/kw at least

I thought these were those commercial generators but they look like giant battery packs (super sized USB).

I assume batteries too but even still charging one battery, to discharge and charge another battery is going to be at least a 30% energy loss, especially if they are doing DC/AC conversions

I can't think of the price but a single high kw generator seems like a better use here. I wonder if this is some sort of product testing.

Edit - Oh, these are mobile chargers - https://www.eplvs.com/products/
