Clip-On Phone Cooler for 67-88mm Devices

The Comvin clip-on cooler attaches to smartphones measuring 67 to 88 millimetres wide. It draws 5 watts over a USB Type-C connection and uses a semiconductor module with a seven-blade fan to pull heat away from the device. A live temperature readout shows the current surface temperature while the cooler runs at 37 decibels. The unit weighs 71 grams and measures 2.24 by 3.22 by 1.37 inches.

Replaces Ad-Hoc Cooling When Throttling Appears

Clip-on fans or passive stands are the usual alternatives for mobile gamers and streamers. The jump to active semiconductor cooling is worth it when sustained loads cause frequency drops or uncomfortable surface heat during long sessions. The built-in NTC protection shuts the unit down if internal temperature exceeds 70 or falls below minus 15, preventing condensation or overheating. Two modes — single-click Movie and double-click Game — let you match airflow to the workload.

Fits In-Bag Carry and USB-C Power Banks

The cooler needs a USB-C power source such as a power bank, wall adapter or laptop port; no battery is included. Its compact footprint and 71-gram mass leave room in a small pouch and add negligible wrist strain during handheld play. The iron housing and multiple vents dissipate heat away from the phone, while the Type-C cable in the box covers the connection. Buyers who need built-in power storage or wireless charging will not find those features here.
