I was skeptical about battery life, but this fan ran for nearly two full camping trips on a single charge. The adjustable stand makes it perfect for sleeping in the tent, and the night light is just dim enough to not be annoying.

The remote control is a lifesaver when I'm lying in bed and don't want to get up to adjust the fan speed. It's surprisingly quiet even on the highest setting, and the night light adds a nice soft glow for camping.

I tossed this in my camping bag last minute, and the 30-hour battery life on low actually got me through two full nights without needing a recharge. The night light is dim enough not to keep me awake but bright enough to find my water bottle.
