120W Bidirectional PD Fast Charging Module Buck-Boost Power Bank Motherboard (Only Mainboard)

120W Bidirectional PD Fast Charging Module Buck-Boost Power Bank Motherboard (Only Mainboard)

Read before Purchasing:
1. The product is a high-power two-way fast charging module, not a toy. Soldering or wiring is required. Please use alligator clips to supply power during tests. Once the product has been welded, returns or exchanges are not accepted.
2. Be sure to pay attention to the wiring of the positive and negative electrodes, because the board does not need to be repaired if it is burnt out due to wrong wiring.

Attention:
- This module must be connected to a battery for use, because the first time it needs to be charged to activate. And powering with a power supply may cause damage to the module, because the power supply cannot be charged. The module is forbidden to be no-load (meaning that the C port is connected to a charger, but the battery is not connected to the battery end).
- The two-way C port of the product can only be connected to one-way electrical appliances or chargers, such as chargers, mobile phones and other electrical appliances. It is forbidden to connect a two-way C-port to the two-way C-port of the module, because it may cause frequent switching between modules and cause the above equipment to be unrecognized, and the above equipment may be damaged in serious cases.
- Batteries with a protection board must be used. Returns and exchanges are not supported after the module is soldered.
- The bidirectional fast charging module is recommended to be connected to a battery pack with a protection board. Without a protective board, it will be impossible to prevent unexpected situations such as short circuits.
- The motherboard is powered by 4 strings of lithium batteries. Batteries are not included in the package.
- Pay attention to the positive and negative poles of the input. Do not reverse the connection. There are 4pcs M2 screw fixing holes on the module, of which the two with pads in the back are inputs, and attention must be paid to distinguishing the positive and negative poles of the input, and they cannot be reversed.

Motherboard Features:
- 120W bidirectional PD fast charging module: It supports almost all fast charging protocols on the market. With bidirectional buck-boost function.
- CS32G020K8U6 master control: The module adopts CS32G020K8U6 main controller and has a built-in program. It is more user-friendly than pure hardware modules, for example, the input and output of the product are designed with slow boost and slow buck to prevent excessive current at the moment of charging and discharging.
- Supports almost all fast charging protocols on the market: The module can output 5V 5A, 9V 5A, 12V 5A, 15V 5A and 20V 6A. The 5-15V of common fast charging modules on the market can only output 3A current. The actual power is very good, which meets the needs of most use scenarios. It supports almost all fast charging protocols on the market, but if your phone does not support non-original fast charging, it will definitely not reach the maximum power!
- Imported inductor heats up less: The inductor is imported and only 12mm x 12mm (0.5" x 0.5") in size, but the heat generation is very low.
- The module is powered by 4 strings of lithium batteries (lithium iron phosphate batteries are strictly prohibited). When fully charged, the module will automatically stop charging. It has the function of automatic protection at low voltage. However, your battery pack still needs a protection board to prevent excessive current and accidents. The battery pack current should be greater than 7A as much as possible. If the battery power is too low, it will definitely not be able to achieve the maximum output, and the battery will also heat up during charging.
- Two-way buck-boost function: The module supports bidirectional buck-boost voltage. With an input of 5V, it can charge 4 strings of battery packs, and when the battery pack is 12V, it can also output 20V.

Notes:
1. It is strictly forbidden to reverse the positive and negative poles of the power supply.
2. It is strictly forbidden to use lithium iron phosphate battery packs or battery packs without a protection board.
3. The current of your battery pack needs to be over 7A for a long time.
4. There are many components on the circuit board, so it is strictly forbidden to touch the chip pins or other components with your hands after power-on. Be aware of static electricity in winter.
