Product Details Data Sheet

What is a power bank circuit board?

The charging and discharging module integrates the microusb interface, and the mobile power circuit board can be used to charge other electronic products. The power bank circuit board integrates overcurrent protection, overvoltage protection and undervoltage protection. The power bank has high precision.

fast charging for short

Fast charging refers to a charging method that can make the battery reach or close to a fully charged state within 1 to 2 hours.
