Sanwa Supply has released a new external smartphone cooler, the 400-CLN036, through its official direct sales site, “SANWA DIRECT.”
Sanwa Supply Launches the 400-CLN036 Smartphone Cooler
The newly introduced 400-CLN036 smartphone cooler uses a Peltier element to quickly absorb heat generated by your device and disperse it through its built-in fan for rapid cooling.
Smartphones tend to heat up noticeably during fast charging or heavy use, which can affect performance—making an external cooler especially useful in these situations.
The 400-CLN036 offers two mounting methods:
you can choose between MagSafe magnetic attachment or a clamp-style grip that hooks onto your device.
PR TIMES
The cooler is powered via USB Type-C and supports two fan-speed levels, allowing you to adjust airflow depending on the situation.
According to Sanwa Supply’s internal testing, using the 400-CLN036 can reduce your device’s surface temperature by approximately 11 degrees Celsius compared to using no cooler at all.
It also features customizable lighting effects thanks to built-in LEDs, which can be switched with a single button press.
Combined with its sleek black body, the illuminated design gives it an appealing, gamer-friendly look.
You can turn the LEDs off—but honestly, if you’ve got lights, why not show them off?
The 400-CLN036 is available from SANWA DIRECT as well as Amazon Japan, Rakuten, and other online retailers.
The price is 3,980 yen (tax included), making it an accessible option for anyone looking to keep their phone cool.
