>>2718220I have picrel. I've taken it camping many times. I use it to charge my phone, my micro air pump/lamp, head lamp and one of those horse shoe shaped fans that you wear around your neck. I keep the solar panel open and in the sun during the day and charge all of my devices at night. I've never had the battery go below 50% even on week long trips. I've heard the single panel ones can't get enough sun to stay charged, but couldn't say personally. But my multi panel one stays charged.
