I have one of these.
Pros: Puts out a LOT more light than the original 3-LED version. Will last an entire weekend if used on medium level, which is plenty of light over a camp stove or in a tent.
Cons: Much bigger /heavier than original, uses a double-ended USB cable to charge (essentially proprietary) which means if you lose the cable you’re SOL. Hard to inflate because of the “pinch valve” and leaks air out the top where the USB port is so it constantly deflates if you don’t hang it from something.
The phone charging feature is a gimmick, IMO. (You’ll never be able to utilize the solar cell to adequately maintain the charge in a smartphone due to problems with physics).
From completely depleted, this takes two full days of sitting in the summer sun to recharge, maybe 3 days this time of year. Personally I prefer my Luminaid.
