ELECOM will release a Peltier-based smartphone cooler in early July to keep phones from overheating[1]. With powerful cooling of up to about -25°C, it curbs the temperature rise that occurs during long gaming sessions or video playback and recording. A 2-way design using a magnet or the bundled holder lets it attach to a wide range of handsets, and it includes a safety feature that detects abnormal temperatures and shuts off automatically. The model number is PWCLPL03BK, with a typical store price of 2,999 yen[1].
Up to -25°C Cooling to Tame Phone Overheating
The new product is a cooling device for smartphones that uses a Peltier element, which becomes cold on one side when an electric current is applied. It suppresses the temperature rise that happens when a device is used for long stretches, such as gaming or video recording. According to ELECOM's own testing, cooling of up to about -25°C is possible[1].
When placed under heavy load, smartphones heat up and become prone to thermal throttling, a process in which performance is deliberately reduced to protect the device from heat. A cooler that chills the phone from the outside is useful when you want to avoid such performance drops or unstable operation. ELECOM positions it as a tool that helps users comfortably enjoy activities like watching live sports broadcasts[1].
On the safety side, it carries an abnormal-temperature sensor that constantly monitors temperature. Even if it becomes too hot, the design shuts the unit off automatically, addressing the risk of the cooling device itself overheating[1].
2-Way Mounting with a Magnet or Holder for Wide Compatibility
There are two ways to attach it. For MagSafe-compatible iPhones and similar devices, it snaps on and off easily with a magnet. For smartphones that do not support MagSafe, attaching the bundled holder makes it usable as well, so it works with a wide range of models, including Android phones[1].
The body is described as lightweight, compact, and quiet, so it stays out of the way even while attached and in use. Note that when removing the smartphone, you must unplug the cable first. Pulling the phone off without unplugging can cause the holder and cable to interfere with each other and risk damaging the connector. Depending on the material and thickness of the case you use, attachment may not be possible[1].
The body also has a quarter-inch screw hole, allowing it to cool while mounted on a tripod. That keeps temperature rise in check even when recording video with the smartphone fixed to a tripod[1].
Power Supply and Eco-Friendly Design
For power, it uses the bundled USB Type-C to USB Type-C cable. Because it runs while connected to a power cable, you can keep using it for long periods without worrying about a built-in battery's remaining charge. On the other hand, a USB AC adapter is not included, so you will need to supply one rated at 5V/2A or higher separately[1].
As an environmental consideration, the product is a "THINK ECOLOGY" certified item that meets at least one of ELECOM's in-house environmental certification criteria. Its packaging consists only of paper, cardboard, and a poly bag[1].
