22.5W Bidirectional Fast Charging Power Bank Module

Most DIY power bank modules are slow (10W max), but this one brings modern speed. It is capable of delivering up to 22.5W of power, meaning it can fast-charge compatible Samsung, Huawei, and iPhone devices significantly faster than a standard charger. It features a versatile port layout: two standard USB-A ports for output, and a Type-C port that works both ways (Input to charge the battery, Output to charge your phone). You simply solder your 3.7V Lithium (18650 or Li-Po) batteries to the B+ and B- pads, and you have a commercial-grade fast charger.
