Adjustable DC Regulated Power Supply

This adjustable regulated power supply is super useful for projects where you need to power a number of devices at a variety of voltage levels and still want to keep things portable. The 6-independent outputs are great for having access to many voltage levels without needing a bulky power supply for each output.

With built-in charging circuit, the power module allows four 18650 batteries 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 makes the product able to power multiple devices steadily at the same time.

Moreover, the equipped short-circuit protection for every output could effectively prevent the product from damages caused by instantaneous or long period short circuit.

The module works with 2300mA/h 18650 battery, which means it can power Raspberry Pi and Pi display simultaneously for 90minutes even when the Pi’s CPU reaches the maximum.

The power module allows a LattePanda Alpha and its display to continuously work 60 minutes when powered by 12V and 5V ports separately. And the NVIDIA Jeston Nano can operate 100 minutes when powered by this module.

If you just plan to use some devices with lower power like development boards and sensors, you may not need to charge it for a week!

Use Method

Charging: TYPE-C charging interface is set on the left side. You can charge it with a 5V2A cell phone charger. It needs 4 hours to be fully charged. 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 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 DC 2.1mm barrel jacks 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.

Note:

18650 battery is not included

There is no protection to stop the combination of the 6 outputs drawing more than the rating of the 18650 batteries, check the total power draw of your devices is still within the rating of your 18650 cells.
