"...with this unit because it powers my wife's CPAP,which is the reason I bought it.First time we used it was camping for 2 nights & it ran the CPAP just fine without recharging.
Recently we had a large power outage,used it to run the CPAP again,.
Not only can you charge it from any 110VAC or 12VDC source the manual shows you how to hook up a portable solar panel to charge it.We live in the southwest,lots of sun here.
Yes it's heavy,but it carries easily & it helps keep your tent on the ground :D"
