Dual USB mobile power bank module

This DIY kit consists of two charging boards designed for building or repairing custom power banks. Each module supports dual USB outputs with a 5V 2.4A rating for charging mobile devices. It is intended for hobbyists who work with lithium battery cells and understand basic electronics assembly.

The board includes built-in protection against overcharging, over-discharging, and short circuits to ensure safe operation. It provides a simple interface for connecting batteries and managing power distribution. This component is a core part of creating a personalized portable charging solution.

By using these modules, users can create a power bank that fits specific size or capacity requirements. The dual port design allows for two devices to be charged at the same time from the same battery source. It is a practical component for electronic projects and custom battery builds.
