Description:

Designed for versatility on the bench or on the go, this dual‑slot USB charger powers up nearly every cylindrical Li‑ion cell you’ll encounter—from tiny 10440 torch batteries to giant 32650 packs. Simply plug the supplied micro‑USB lead into any 5 V/2 A wall adapter, power bank, or solar panel and the smart CC/CV controller takes care of the rest—delivering up to 1 A in single‑slot mode or 2 × 500 mA simultaneously. Independent status LEDs show exact progress and the built‑in safety suite shuts everything down at 4.2 V, so your cells stay cool, balanced, and ready for action without manual guess‑work.
