This DC-DC step-up voltage regulator board has a step-up switching regulator on it. The board's output is a USB connector. It's input voltage is between 1V and 5V so you can easily power up the systems that uses 5V supply voltage, by using a 3.7V Li-Po or 2 AA Battery. You can draw 600mA of current through USB output. In this way you can make your own power bank.
- Input Voltage: 1-5V
- Output Voltage: 5V
- Up to 94% Efficiency
- Output Current: 600mA
- PCB Size: 34x16mm (Without USB Connector)
