Tired of constantly buying disposable batteries? This compact 4-slot USB charger is exactly what you need for all your AA and AAA NiMH rechargeable batteries! The design is super convenient - you can charge 1 to 4 batteries at the same time, and the independent slots mean you can mix AA and AAA batteries without any issues.

The universal USB connection means you can plug it into any USB port - your laptop, wall adapter, power bank, or car charger - making it perfect for home, office, or travel. It's packed with safety features too: overcharge protection, overcurrent protection, reverse polarity protection, temperature protection, and short circuit protection keep your batteries and devices safe. The smart charging management IC handles everything automatically - starting with constant voltage low current, then 500mA high current charging, and finally maintenance charging. At just 7.8 ?? 6.2 ?? 2.5 cm, it's incredibly compact and portable. Just note that it works with NiMH batteries but isn't suitable for low-capacity Ni-Cd batteries due to the higher current.
