This module can be connected to a single LiIon or LiPo battery (or multiple batteries connected in parallel) and delivers a maximum of 22.5W of USB power.
At full load, this module draws 22.5W. At battery voltage level, this results in a current of up to 6.5A. Make sure the discharge rate of your battery is sufficient. Also make sure you use appropriate wiring.
USB Ports
The board comes with five connectors that can be used concurrently with the entire variety of USB devices including Android and iOS:
- 2x USB-A, output only, supporting QC3/QC2/AFC/FCP/SCP/PE2.0/PE1.1/SFCP/VOOC
- 1x USB-C, input/output supporting PPS/PD3/PD2/QC4+/QC3/QC2/AFC/FCP/SCP/PE2.0/PE1.1/SFCP
- 1x Micro-USB input/output, supporting QC2/AFC/FCP/SCP/PE1.1
- 1x Apple Lightning, input/output, supporting PD Fast Charge at 5V/2.4A
Protection Features
The board comes with a presoldered temperature probe to protect from over-temperature. The probe needs to be mounted close to the attached battery.
The board comes with over- and under-voltage and short-circuit protection.
LEDs / Indicators
On the back, LED1 indicates fast charge mode. LEDs D3, D4, D5, and D6 show the current state of charge:
Charging
LED state while charging:
| State of Charge | LED |
|---|---|
| 100% | all |
| 75% | D3-D5 on, D6 blink |
| 50% | D3-D4 on, D5 blink |
| 25% | D3 on, D4 blink |
| 0% | D3 blink |
Discharging
LED state while discharging:
| State of Charge | LED |
|---|---|
| 100% | all |
| 50-75% | D3-D5 on |
| 25-50% | D3-D4 on |
| 5-25% | D3 on |
| 1-5% | D3 blink |
| 0% | D3 blink |
Button
A button on the side can be used to wake up or turn off the powerbank.
The powerbank will automatically wake up when a load is connected.
Setting Battery Capacity
The board comes with a unique coloumb counter to show the battery state of charge. For it to work, the board needs to “know” the total battery capacity.
The battery capacity is set by resistor R8 (next to the temperature probe connector). On the board examined, this was a 55C SMD resistor (36.5kOhm, SMD Code Converter).
The formula to calculate the resistor for a given battery capacity is:
Ohm = (x mA + 2000) x 5 / 3
The presoldered value 36.5kOhm sets the battery capacity to 20.000mA:
(36500 * 3 / 5) - 2000 = 20000

There is no third-party provider, no disrupting ads, and everything remains transparent inside github.
Github Users Yes, Spammers No
To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.
If you don’t have a github account yet, go get yourself one - it’s free and simple.
If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.
Discussions
For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
