AeroChill

Has been running for two full days on a single charge, and the motor is quieter than my old unit. The standard model’s airflow is surprisingly strong for its size. Perfect for keeping cool on my desk.

Finally found a portable fan that actually fits in my pocket without bulging, and the battery easily lasts through my whole commute. The airflow is strong enough to cool me down on hot subway platforms without being annoyingly noisy.

The cooling effect lasts much longer than those cheap gel packs I've tried, and it's quiet enough to use while I sleep. Setup was straightforward right out of the box.
