if you’d plug a device into a regular wall outlet for power, it’s ac. if your power bank has an internal inverter and provides an ac outlet, you should be able to just plug it in–provided its power demands fit within the output specs of the power bank. a normal box fan using 20-75w (approximately what ours here are, depending on age. newer models are more efficient) should be ok.
if you’re running off a battery bank, then run as much DC as you can. if a generator, AC.
It’s a little 600W emergency power supply, not a generator.
use as much DC as you can
