Frequently Asked Questions Frequently Asked Questions

Fan vests only move air and depend on sweat evaporating, so they lose effectiveness in high heat and humidity. This vest circulates ice water against your back to cool you by direct contact regardless of humidity — with fans adding airflow on top.

The cold comes from the ice, not the battery. A set of reusable ice packs gives about 1 hour of strong cooling; a frozen 350ml bottle about 1.5 hours. Refreeze and swap in fresh ice packs for all-day cooling, and the fans keep airflow going the whole time.

Yes — it runs on any 5V USB power bank. The Kit includes the Venustas 5000mAh battery (USB-A); for Vest Only, use that battery or any 5V/10000mAh bank.

Light surface condensation is normal in humid heat. Wear a thin base layer underneath and avoid aiming the cold directly at bare skin for long periods.
