22.5W Fast Charging Digital Display Power Bank Mainboard TFT Color Screen DIY Module Supports PD QC SCP VOOC for Mobile Devices

Features:
1. Multi-protocol compatibility: support PD/QC/APPLE and other mainstream protocols, adapting to all brands of equipment fast charging
2. Quadruple safety protection: overcharging/over-discharging/over-voltage/overheating intelligent protection, to avoid potential safety hazards
3. TFT color screen display strength: real-time display of power/voltage/temperature, status at a glance
4. Protection-free board design: integrated protection function on the main board, directly weld the battery to save space and simplify assembly
5. Intelligent self-learning power: automatically calibrate the power display after the first use, accurately reflecting the remaining battery power

Parameter:
Product Name: 22.5W fast charging module
Input Parameters: 5V3A/9V2A/12V1.5A
Output Parameters: 5V3A/9V2A/12V1.5A/10V2.25A
Interfaces: Configure 1 Type-C fast charging port (can be charged as well as output) + 2 USB fast charging output ports
Protocol: PD, QC, APPLE, FCP, SCP, VOOC
Function: with over-charging / over-discharging / over-voltage / overheating and other kinds of protection, high conversion rate, current and voltage stability
Note: 22.5W is the super fast charging protocol, bidirectional fast charging is the PD20W protocol, multiple interfaces at the same time the output of the fast charging of no

Assembly instructions:
1. Because the motherboard screen is fragile, upon receipt, please power on the screen to test whether the screen is normal after welding on the tin, the screen wires will be extruded by external forces will be spent on the screen burst screen, please pay attention to protect the screen when using.
2. Normal use, the battery wires are welded up, wire twisting / alligator clips / spring box and other access methods will lead to insufficient power supply to affect the charging and discharging, the battery positive and negative need to do a good job of insulation protection to avoid damage caused by the use of the process of touching with the motherboard.
3. motherboard B + position connected to the battery positive, B – position connected to the battery negative, do not connect the reverse, the reverse will burn the motherboard, burn board IC there will be traces, only the reverse or touch connection will occur.
4. Access to the battery to use 3.7V ternary lithium batteries, lithium iron phosphate batteries can not be used, the battery parallel welding, not in series, series voltage is too high will burn the motherboard.
5. The motherboard has a protection function, welding batteries do not need to add a protection board, the battery protection board has a limit on the current, beyond the limit will disconnect the output.

Instructions for use:
1. On the activation of cell phone fast charging, cell phone fast charging public and private protocols to distinguish between the motherboard adopts intelligent fast charging chip, compatible with the mainstream public fast charging protocols on the market to meet the needs of different brands of cell phones for fast charging, before placing an order, please confirm that their cell phones are compatible with the public protocols, to avoid not being able to trigger the fast charging!
2. On the charging of the motherboard heat problem, charging treasure in the work, the current through the motherboard and the chip, energy conversion will have loss, this part of the loss in the form of heat emitted, fast charging, the power is large, the heat is more obvious, this is a normal physical phenomenon.
3. Just connected to the battery digital display power will be inaccurate, the power meter supports battery capacity self-learning function, charge and discharge cycle a few times after the normal.
