The 5V Step-Up Power Module Lithium Battery Charging Protection Board or the Power bank module contains a single chip that has multiple applications. This module is widely used as a power bank application, as it can provide large load currents and large discharge currents up to 1A, which is ideal for device charging. The module has onboard LEDs to indicate charging and discharging.
Specifications:
- Input Voltage: 3.7V – 5.5V DC
- Output Voltage: 5V DC
- Output Current: 1A
- Charging Current: 1A
- Discharging limit: 2.9V
