The IP5328P Power Bank Module is a complete two-way fast-charging circuit board that turns ordinary 3.7V lithium cells (18650 or Li-Po) into a full-featured fast-charging power bank. Built around the IP5328P power management chip, it supports up to 18W bidirectional fast charging — it can fast-charge your phone and be fast-recharged itself through the same board.

Just connect one or more 3.7V lithium batteries in parallel, and you get USB-A, USB-C, and Micro-USB ports with automatic 5V / 9V / 12V output, plus LED indicators showing the remaining battery level. It's an ideal ready-made core for DIY power bank builds and portable power projects.
