Note: After the first power is powered, there is no output, and you need to input to activate with a 5V voltage at the charging port. Read before buying:

1: The battery that can be used: 18650 lithium battery (no protective board)

Requirements to access battery: lithium battery (18650 lithium battery) with 3.3-4.2V: cannot be connected to other batteries, such as 1.2V 18650 nickel-metal hydride batteries, 3.2V iron lithium batteries, all dry batteries, 12V lead-acid batteries

2: Charging and discharge protection: Circuit board built -in lithium battery protection IC, with overvoltage protection, overcurrent protection, under pressure protection, etc.

3: 4 verses can be installed with a maximum of 4 knots 18650 batteries (3 sections, 2 sections, and 1 section are also wood problems).

4: Charging input requirements: The most matched is a charger above 5V2A. Any other 5V constant voltage power supply can be used as a charging input power supply. Note that it does not support the PD charger

5: After the battery is just connected, it is usually output to the circuit board charging. If the mobile power is not used for a long time, the power supply will be turned off and the output will be turned on. USB output parameters: 5V/2.4A (large current equipment, fast charge mobile phone, 5 -inch screen mobile phone, large power, do not use too bad batteries, otherwise it cannot be output normally and the power cannot be accurate.)

Enter interface: Type-C port (not supported PD)

Enter parameter: Standard current 2A

Electricity display: Level 4 LED light shows the power, the non -working state intelligent automatic shutdown Set = shell+booster board (no battery) Note: Although mobile phone mobile power can be stabbed by most mobile phone models, i....
