【In-vehicle】Same system as a compact refrigerator! Cooling holder to prevent smartphone overheating
When using an iPhone or smartphone as a car navigation system, the issue becomes the device's inherent "heat". There are risks of battery degradation or malfunction, operational failures, and in some cases, the dangers of fire or burns. To drive with peace of mind, I want to set up a smartphone holder equipped with a Peltier element.
It can cool the smartphone installation surface by up to 3°C.
Drawn in by its cool appearance, I checked out Sanko's "Car-Mounted Cooling MagSafe Holder." As its name suggests, it is said to effectively cool down smartphones to prevent overheating. Although it is designed specifically for MagSafe, it can also be used with non-MagSafe compatible smartphones by using the included plate.

The main feature is the Peltier element cooling plate that uses the same cooling system as a compact refrigerator. This is placed on the smartphone mounting surface, allowing for cooling simply by securing the smartphone. The cooling mode can be set to three levels: low, medium, and high, enabling quick cooling as well. The surface temperature of the plate is about 3°C on high, which indicates that it is quite cold.

The pole joint arm operates flexibly.

The orientation of the arm can be changed 360° and has four movable joints, each capable of moving 180° up and down, allowing it to bend or stand upright.

Furthermore, since the pole joint can be rotated to any angle, there are no restrictions on the orientation of the smartphone. The arm is made of aluminum and has a sturdy construction, so it remains stable even when subjected to vibrations while driving.
It can be used not only in the car but also at home or in the office.

It can be fixed with a sticky gel sheet, so it is recommended for use not only in the car but also at home and in the office. It seems useful for checking recipes, studying, and remote meetings. You can binge-watch dramas since the smartphone does not get hot, no matter how many videos you watch.
Please note that the power for the cooling plate is USB powered and does not have a charging function.
