Elecom PWCLPL03BK Peltier Cooler Cools Phones to -25C

Smartphone gamers and mobile videographers face a persistent hurdle as devices overheat during intensive sessions. Elecom addresses this issue with the PWCLPL03BK, a compact cooler that actively manages heat to maintain performance. This accessory allows users to sustain high frame rates or long recording times without the device slowing down due to thermal limits.

Compact magnetic accessory with tripod mount

The device relies on Peltier cooling technology to actively lower the temperature of compatible smartphones. It connects to the phone via a magnetic attachment or a mechanical holder, ensuring a secure fit during use. The cooler supports MagSafe-compatible iPhones and other devices that work with the included holder.

Specifications

• Max Cooling Temp: Approx -25°C
• Power Input: USB Type-C
• Weight: Approx 85g

Elecom claims the unit can reduce smartphone temperatures to approximately -25°C. This significant drop helps prevent thermal throttling, which is the performance reduction that occurs when hardware gets too hot. The unit measures 116mm in width, 48mm in depth, and 64mm in height, weighing just 85g. It draws power through a USB Type-C port, though users must provide their own 5V/2A AC adapter.

The cooler includes a standard 1/4-inch tripod screw hole on its base. This feature allows users to mount the device on a tripod for stable video recording or livestreaming setups. The magnetic and holder mounting options provide flexibility for different phone cases and user preferences.

The PWCLPL03BK is priced at 2,999 JPY (around $18.54), which is around $18.54. Elecom plans to begin sales in Japan starting in early July 2026. The product is currently limited to the Japanese market with no immediate international availability announced.

This launch adds a specialized cooling solution to the growing market of smartphone accessories. It targets users who need reliable thermal management for extended gaming or content creation. The combination of active cooling and mounting options provides a practical tool for mobile performance stability.
