So far so good! Went backcountry camping over the weekend using the powerbox 40 for my CPAP. Worked like a charm. Figured I could go the better part of the week before I would need solar panels.
I purchased this Powerbox for camping. It runs my base camp. It powers my LED Lights, charges my phone and laptop, and keeps the heater on during the night. It fills my air mattress, lets me use my electric skillet. I took it on a 4 day camping trip on Orcas Island and it had enough charge for the entire trip. It works well with the solar panel I bought. I got the cheap real bulky panel. I would get the folding one next time. The box is really sturdy and the build quality looks good.
