Will not power a hair dryer
Does not come with solar panel. Must purchse seperately.
any solar panel between 50w and 100w will work fine. the panel cable connector must match the generator connector.
Will not powrr CPAP machine.
Depends on the voltage of the appliance. However there is NO info to check with manufacturer for questions and issues. Be better off gettin a 1000w Renogy for a few mire bucks. Lot more power for the money.
what is a cpap device?
No. Only very small things, like a cell phone. Best used for recharging small things.
Will not power a CPAP.
I wouldn't know, I charged it by plugging it in at home before I left for the cabin. It charged my Dell pc once then never worked again. Pathetic product. Taking it back.
