Safe to power an amp with a home backup battery?

[jacobarber]

I'm just throwing out a hypothetical. I have a couple of EcoFlow Delta2 batteries and was wondering if there are any concerns about using one of these to (temporarily) power an amp. So long as it can essentially provide a really clean 1800w, 120VAC @60Hz on a 13A circuit.

I don't see why not, if it's clean and has the power capacity. A tube amp is just an inefficient space heater.

I've run my amp on my ECO Flow Delta Pro 3 backup system. Worked fine.
