What is Two-Way Charge/Bidirectional Charge？

A feature allowing power banks to both receive and output power, enabling them to charge devices while being charged simultaneously.

Simply Put:

Imagine a busy highway with traffic flowing smoothly in both directions. Just like cars can enter and exit at different points, a two-way charge power bank works like a smart interchange. It receives energy from one direction (being charged) while sending it out in another (charging devices). This bidirectional flow keeps power constantly moving, improving both efficiency and convenience, just like a well-designed road system keeps traffic running without delays.
