1. Support 140W maximum power to meet the demand of high performance equipment fast charging 2. Support PD3.1, PD, QC, AFC, FCP and other protocols, suitable for a wide range of devices. 3. Adopts Type C interface, easy to plug and unplug, enhance user experience. 4. Built-in intelligent identification chip, automatically match the best charging mode, protect the device. Voltage: 28V Current: 5A (maximum) Default highest gear description: When setting the highest gear 28V, when the connected charger or rechargeable treasure supports 28V output plug it in and it output 28V; if the charger or rechargeable treasure only supports 20V output, then plug it in and it output 20V; if it only supports 15V output, then plug it in and it output 15V and so on. When the highest block is set to 20V, if the connected charger or rechargeable treasure supports 28V output, then plugging it in output 20V, and so on. Note: This circuit board is only protocol decoy, does not support charging, not boost or buck, and can not be connected to the boost board and buck board to use, the maximum overcurrent 5A, as for the corresponding number of V how many A can be dependent on the use of the charger has to do with the circuit module has to do with the private agreement of the cell phone charger or the ancient cell phone charger protocol does not match or no fast-charging protocols do not support the decoy! Specification:A:NO DC Socket Color: Black Material: PCB Package Contents: 1 board decoy Module Only the above package content, other products are not included. Note: Light reflection 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.
