BUYING GUIDE
Do Phone Coolers Actually Work?
Yes — semiconductor (Peltier) coolers can drop surface temperatures by 15-25°C, which directly prevents thermal throttling. This translates to more stable frame rates in demanding games like Genshin Impact, PUBG Mobile, and Honkai Star Rail.

Powered vs Battery-Powered Coolers
USB-C powered coolers are more effective but tether you to a cable. Battery-powered models offer freedom but typically cool less aggressively and need recharging. Choose based on whether you game at a desk or on the go.
