Type-c USB 22.5W Bidirectional Fast Charger Buck Converter Mobile Power Module Motherboard With Display Support PD/QC/SCP/VOOC

Features:
1. Multi-protocol full compatibility: supports mainstream protocols such as PD/QC/APPLE, and is compatible with fast charging of all brands of equipment
2. Quadruple safety protection: intelligent protection for overcharge/over-discharge/overvoltage/overheating to avoid safety hazards
3. TFT color screen shows strength: real-time display of power/voltage/temperature, the status is clear at a glance
4. Protection board-free design: motherboard integrated protection function, direct welding of batteries to save space and simplify assembly
5. Intelligent self-learning power: automatically calibrate the power display after the first use, accurately reflect the remaining power

Product parameters:
Product name: 22.5W fast charging module
Input parameters: 5V3A/9V2A/12V1.5A
Output parameters: 5V3A/ 9V2A/12V1.5A/10V2.25A
Interface: 1 Type-C fast charging port (chargeable and output) + 2 USB fast charging output ports
Protocol: PD, QC, APPLE, FCP, SCP, VOOC
Function: with multiple protections such as overcharge/over discharge/over voltage/overheating, high conversion rate, stable current and voltage
Note: 22.5W is a super fast charging protocol, two-way fast charging is a PD20W protocol, and multiple interfaces output at the same time without fast charging
Assembly instructions:
1. Because the motherboard screen is fragile, please power on and test whether the screen is normal after receiving it before tinning and welding. The screen cable will be squeezed by external force and the screen will explode. Please pay attention to protect the screen when using it.
2. In normal use, the battery wire is welded on. The connection methods such as wire twisting/crocodile clip/spring box will cause insufficient power supply and affect charging and discharging. The positive and negative poles of the battery need to be well insulated to avoid contact with the motherboard during use and cause damage.
3. Connect the positive pole of the battery to the B+ position of the motherboard, and the negative pole of the battery to the B- position. Do not connect them in reverse. Reverse connection will burn the motherboard, and the IC will leave traces. This situation will only occur if it is connected in reverse or bumped.
4. Use 3.7V ternary lithium battery to connect the battery. Lithium iron phosphate battery cannot be used. The battery is welded in parallel, not in series. If the series voltage is too high, it will burn the motherboard.
5. The motherboard has a protection function. The welded battery does not need a protection board. The battery protection board has a limit on the current. If it exceeds the limit, the output will be disconnected.

Instructions for use:
1. Regarding the issue of activating mobile phone fast charging, mobile phone fast charging has a distinction between public and private protocols. The motherboard uses an intelligent fast charging chip, which is compatible with the mainstream public fast charging protocols on the market and can meet the fast charging needs of mobile phones of different brands. Please confirm whether your mobile phone is compatible with the public protocol before placing an order to avoid failure to trigger fast charging!
2. Regarding the issue of motherboard heating during charging, when the power bank is working, the current passes through the motherboard and chip, and there will be energy loss in the energy conversion. This part of the loss is dissipated in the form of heat. When fast charging, the power is high and the heat is more obvious. This is a normal physical phenomenon.
3. The digital power display will be inaccurate when the battery is just connected. The power meter supports the battery capacity self-learning function, and it will be normal after several charge and discharge cycles.
