SPECIFICATIONSBattery: noBrand Name: XMSJCertification: CE,FCC,RoHS,ULChoice: yesHigh-concerned chemical: noneOrigin: Mainland Chinasemi_Choice: yes Product description Product name: Compound vapor chamberProduct category: 1. ordinary model (used with semiconductor cooling back clip, with conductive silicon paper on the back).2. Magnetic attraction (universal magnetic attraction and back clip radiator, with double-sided tape on the back). Method of use: It is attached to the back of the mobile phone and used with the radiator to increase the heat dissipation area and cool the CPU and camera of the mobile phone. The magnetic attraction products are internally embedded with magnetic attraction sheets, which are glued seamlessly, and the magnetic attraction radiator can be directly adsorbed and used. Attention: Part of the mobile phones are not applicable. Before buying, please confirm whether your mobile phone can be used. If it doesn't match, please don't place an order.If there is any problem with your product after you have received it,please contact us first. We will try our best to solve the problem. Semiconductor refrigeration+,Large area radiating plate.For mobile phone hot spots, large area vapor chamber is used to quickly neutralize heat and achieve uniform heat dissipation.Aluminum sheets transfer refrigeration to superconducting silica gel to neutralize heat. Stick strongly and don't fall off.Strong adhesive, firm adsorption, not afraid of radiator falling. Do not hurt the phone, with silicone protection.Easy to take and paste, with silicone protection, soft and does not hurt the machine, do not scratch your hands. The thickness is only 1MM, which closely fits the mobile phone and has a light and thin experience. It is equipped with a magnetic radiator, which closely fits the mobile phone and seamlessly conducts cold. It is matched with the back clip radiator, which fits the mobile phone closely and seamlessly conducts cold. Product size
