Linogy 4-Slot USB-C Charger for Li-ion AA & AAA Rechargeable Batteries

4-Slot USB-C Charger for Li-ion AA/AAA Batteries: The Linogy 4-slot USB-C battery charger is designed for rechargeable Li-ion AA and AAA batteries only. It supports charging 1–4 batteries at the same time using a 5V/2A (10W) USB-C input and can fully charge up to four batteries in about 3 hours. AA and AAA batteries fit directly into the charging slots with no adapter tray required.

Incompatible Battery Detection and Built-In Safety Protection: The charger automatically detects incompatible batteries, including NiMH and alkaline batteries, and prevents them from charging. Built-in protection includes over-voltage, over-current, short-circuit, over-temperature, and reverse-polarity safeguards.

Individual LED Status for Each Charging Slot: Each of the four charging slots has its own LED indicator to show charging, fully charged, or error status, making it easy to check the status of each battery independently.

Compact USB-C Charger for Travel and Everyday Use: The Linogy 4-slot charger is 32% lighter and 26% smaller than traditional 4-slot battery chargers. Its USB-C input can be powered by compatible wall adapters, power banks, laptops, and car chargers, making it suitable for travel, photo and video shoots, and everyday portable use.
