The external DC-DC main power supply + EMARK power supply of the chip is completely different from the official public version circuit, and the efficiency is improved by about 2%. The main control IC is no hot when the power is high The and first trigger external EMARK circuit replaces a bunch of SBMOS, greatly improves the stability and reduces the board area, which is completely different from the official public circuit, Brand new power tube 5C670 x 4, Japan's X7R -volume light yellow new chip capacitors x 7, no need for colorful dismantling refurbishment or small enough to see where or dark brown Y5V electronic waste capacitors certified KRCONN high-quality C port, resistant to plugging and unplugging, resistant to high current, Taiwan Province to the 125 high temperature solid capacitors x 2, I Taiwan Province America and integrated high frequency inductor, The default is 4 strings of batteries, and the jumper 3 is connected to the starting mark to set 3 strings. If you need other voltages, you can change the resistance according to the 2368 document. After the battery is connected, please charge and activate it to reverse the output. Volume: 50 x 26 x 17.5mm excluding XT60 plug Input: Default 4 strings of batteries 12-16.8V, XT60 male socket Output: 100W bidirectional PD3.0, compatible with QC2.0-3.0, is -SCP, , note no PPS Static power consumption: about 0.4mA Output ripple: about 40mV for 5V2A, about 300mV for 20V5A Style: NO XT60 Color: As Shown Material: PC+metal Package Contents: 1 x Fast Charging 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.
