Baiwu, with a width of 239mm or less, can be used. The amount of splicing plate can be changed freely according to the size of the plate It is light and does not block your hand. When you connect power, you can cool down. semiconductor black technology specially sets an air conditioner for your favorite machine. So that the heat of the mobile phone can escape 35mm contact area Exquisite cold conduction process, electroplating process, embedded scratch resistant layer and pattern, aluminum sheet with electric heating coefficient of 237w / (m.k) can quickly gather cold and evenly diffuse to the heat of mobile phone, and the thermal conductivity of liquid water (about 0.59w / (m.k)) The materials and details of the product are strictly controlled, and cold and hot partitions are used on both sides of the semiconductor to block consumption. The 9-blade fan is optimized and upgraded, with a speed of up to 7000 rpm. The daily fan speed is about 4000-5000 rpm. The strong speed supplies air to the heat dissipation aluminum column and brings out the semiconductor heat from multiple heat dissipation seals Rated power of fan: 5W Charging input: 5V / 1.7V Charging interface: type-C Applicable model: width 239mm Feature 1:Tablet radiator Feature 2:Mobile phone radiator Feature 3: Cooling back clip Feature 4:Mobile phone cooling fan Colour:black Material:ABS Size:23.9 x 6.5 x 3.4cm Package Contents: 1 x radiator 1 x charging cable Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
