Quick answers about cooling, battery, and buying.
The Coolhill Pro Handheld uses a semiconductor cooling plate that gets genuinely cold against your skin — so you feel an instant temperature drop, not just moving air. The Desk and Clip-On fans focus on strong, quiet airflow.
Every Coolhill fan charges over standard USB-C. Use any phone charger, laptop, power bank, or car charger. A full charge takes roughly 2.5–4 hours depending on the model.
Runtime depends on speed. At lower speeds the fans run for several hours to a full day; at maximum turbo, expect shorter sessions. The Clip-On Mini runs up to 10 hours on a charge at moderate speed.
The Desk Fan uses noise-reduction technology and can run as low as ~28 dB — quiet enough for a nightstand. All models are quietest at lower speeds.
Our fans are sold on Amazon.com. Each product page links straight to its Amazon listing for current pricing and checkout.
