■Motherboard solution: China Resources Silicon CS4967/Nanjing Ruihe 1030■Input port: Type-C interface■Input voltage-current: 5V/2A MAX, 9V/2A MAX, 12V/2A MAX corresponding to wireless charging output 5V/1A MAX(5W), 9V/1.12A MAX(10W), 9V/1.67A MAX(15W)■Input protocol: PD3.0/PD2.0/QC2.0/QC3.0 (above 18W)■Output power: QI protocol 5W/Apple 7.5W/ Samsung 10W/15W(Max)■Compatible matching: Compatible with QI protocol 5W/Apple 7.5W/ Samsung 10W/15W(Max) Adapt to mobile phone size: 4.7-6.9 inch mobile phone■Charging efficiency: 5W≤73%, 7.5W≤75%, 10W≤78%, 15W≤82%■Charging frequency: 110-205 kHZ■Charging distance: ≤6mm (recommended working distance 2-3mm)■Protection function: over temperature/over voltage/over current protection, short circuit protection, intelligent identification.Metal foreign body detection: Yes Charging reminder: LED indication■Material: ABS+PC+glass fiber■Size/weight size: 108*64.5*20MM weight (including suction cup bracket): 214G■The working principle of the clamp arm: power on, the clamp arm automatically opens, puts the mobile phone, FOD automatically detects the mobile phone, and the clamp arm automatically closes.There are two ways to take out the mobile phone when it is powered on:The first type: Press the mechanical button, the left and right gripping arms will automatically open, and the mobile phone will be removed; the gripping arms will remain open;The second type: Pull out the mobile phone directly. After the mobile phone is pulled out, the clamp arm remains closed due to the elastic force.The way to take the mobile phone in the power-off state: After the car is turned off, pull out the mobile phone directly, and the clamp arm keeps closed due to the elastic force.
