Small and portable, this Adjustable DC Regulated Power Supply with 6-way output is a practical power supply for your projects.

With a built-in charging circuit, the power module allows four unprotected rechargeable 18650 batteries (not included) to be connected in series and features 6 independent outputs: 2-way 5V/5A, 1-way 9V/3A, 1-way 12V/2.5A, 1-way 24V/1A and 1-way 1~20V(2.5A) adjustable output.

Each output employs an independent power chip, which allows the board to power multiple devices steadily at the same time. There's also short-circuit protection for every output, protecting it from damages caused by instantaneous or long periods of short circuit.

Note: 18650 batteries not included

Usage & Charging

Charging: TYPE-C charging interface is set on the left side. You can charge it with a 5V 2A phone charger or similar. It needs ~4 hours to be fully charged (varies depending on the batteries used). The charging indicator next to the interface lights up in red in charging and turns off when fully charged. Also there is an indicator at the interface for displaying the battery's remaining electricity quantity.

6-way output: 2xUSB 5V, 9V, 12V, 24V and 1~20V adjustable output. 6 outputs can be used simultaneously. All outputs are designed as DC2.1 interface except USB.

The rotary encoder is used to adjust the voltage from 1 to 20V with an accuracy of 0.1V. The LED digital tube next to the encoder displays the current voltage. Short press the encoder switch to adjust the voltage by 0.1V or 1V, and long press to lock the current voltage. Long press again to unlock it.

There are buttons set on 9V, 12V, 24V and 1-20V respectively for enabling or disabling the power output. Press once to turn on and press again to turn off. The LED of the corresponding output will be turned on when enabled. The USB outputs do not have switch buttons.
