Product description: Adjustable battery power supply DC 1-20 V / 3 A - multi range - DFRobot FIT0674
Portable battery power supply created by DFRobot. The power supply has four slots for 18650 Li-Ion batteries, allowing you to power all kinds of devices in places where there is no access to an outlet to connect the power supply. It is equipped with six output connectors, four DC sockets: 9 V / 3 A; 12 V / 2.5 A; 24 V / 1 A; adjustable from 1 V to 20 V / 1.5 A to 3 A and two USB sockets: 5 V / 3 A. Each output has short-circuit protection, which effectively prevents damage to the product caused by temporary or long-term short circuit. The module works with 18650 / 2300 mAh batteries, which means it can power a Raspberry Pi with the display connected for 90 minutes, even when CPU usage reaches its maximum. The LattePanda Alpha and the display can run for 60 minutes on 12 V and 5 V power. The NVIDIA Jetson Nano can operate for up to 100 minutes.
Adjustable battery power supply, multi-band.
Description of the components on the battery power supply board.
How to use the portable battery power supply
Charging: the module has a built-in charger circuit, which allows you to charge 18650 batteries via USB C connector with a voltage of 5 V / 2 A. The batteries will be charged within 4 hours. Charging of batteries is indicated by a red LED, which will go off when fully charged. There is also a remaining battery power indicator on the module.
Power supply outputs: the module is equipped with two USB type A 5 V / 5 A sockets and DC 5.5 / 2.1 mm outputs: 9 V / 3 A; 12 V / 2.5 A; 24 V / 1 A and adjustable from 1 V to 20 V / from 1.5 A to 3 A. Six outputs can be used at the same time.
The output voltage of the last connector is adjusted with a potentiometer, with an accuracy of 0.1 V. A digital display next to the knob shows the current voltage. A short press on the knob adjusts the voltage from 0.1 V or 1 V, a longer press will lock the adjustment, a long press again will unlock the knob.
Four 9 V / 12 V / 24 V / adjustable outputs, can be switched on / off with the buttons. Each output is indicated by an LED.
