We compared two rechargeable USB desk fans: the Otlonpe 4000mAh Portable Desk Fan and the TriPole 2000mAh Rechargeable Desk Fan.

What we looked at

Battery size, runtime, speeds, noise claims, and price.

The verdict

If you want the bigger 4000mAh battery, up to 23 hours of cooling and 4 speeds, the Otlonpe is the pick at £13.98. If you would rather save £0.99 and get an LED display with 180° adjustment, the TriPole is the alternative, at £12.99.
