I took this camping last weekend and the battery life is no joke—it ran on low for two full nights without needing a recharge. The fold-down design made it easy to pack, and the remote came in handy when I was already in my sleeping bag.

The remote is the reason I picked this over cheaper fans, and it actually works from across the room without pointing it directly at the unit. Set it up on the desk during the day and folded it down for the tent at night, and the battery held up for both trips without a charge.

Brought this on a camping trip last weekend and was surprised how long the battery lasted—easily got through two nights on the lowest speed. The remote control is handy for adjusting it from across the tent.
