Great for a tent, pnichols. It would do bacon and eggs for breakfast, with a NuWave induction cooker limited to 700 watts. It is attractively priced.
The location my condo is in has infrastructure that is 70 years old. There are a lot of power outages. Every time I look at these units I find I could roll my own more cheaply, for the capacity I want. Add that to a 1000 watt psw inverter that I carry as a back up which would serve me well at the Condo.
So far, I've managed on my laptop battery and a couple of batteries intended for cell phone charging. I do have a boost pack for starting the car that I could use with the 1000 watt inverter. So my costs to have back up would be nearly zero.
