Name of the part:
2S/3S 18W Mini Fast Charging Module
Previous work, similar parts:
While there are Fritzing parts for various battery charging modules, this one is notable for its very small size, USB Type-C input, and support for fast charging protocols to charge multi-cell (2S/3S) battery packs efficiently. It is a more compact and modern alternative to older, larger charger boards.
