About This

• Passive Evaporative Cooling Aid — This patch uses water evaporation to help carry heat away from the back of your phone. It contains no fan, battery or electronic refrigeration and is not intended to provide fan-cooler or semiconductor-level cooling.
• Best with Direct Contact and Open Airflow — Apply directly to a smooth phone back or use with an open bumper-style case. Thick, wallet, fully covered and some foldable-phone cases may reduce contact and cooling performance.
• Refill as the Patch Dries — Add only enough water to make the patch damp. Reapply water after it dries. Actual cooling duration varies with temperature, humidity, airflow and water amount.
• For Moderate Heat Buildup — Designed to provide supplemental cooling during GPS navigation, gaming and short periods of outdoor phone use. Results vary by phone, workload, ambient temperature, humidity, airflow and case type.
• Washable, Reusable 5-Pack — Includes 5 cooling patches and 2 refill bottles. Keep the adhesive surface clean, use only a few drops at a time, and keep water away from charging ports, speakers, cameras and other openings.
