4-Slot Rechargeable Battery Charger, Fast Charging for AA and AAA Batteries with USB Port

[Compatible with AA/AAA Batteries] Rechargeable AA/AAA nickel-chromium/nickel-hydrogen batteries are used, and up to 4 batteries can be charged simultaneously.

[Intelligent Constant Current and Constant Pressure Charging] Controls voltage and temperature to ensure safe and complete charging. You don't have to worry about safety during charging because the battery automatically stops charging when fully charged.

[LCD Sensor Lamp Display] The charger has a smart LCD indicator light. When the battery is charging, the corresponding battery indicator turns red. The indicator automatically turns green when the battery is fully charged.

[Heat Dissipation Window Design] Heat dissipation windows are designed at both ends of the charger to dissipate the heat generated during battery charging. Some heat may be generated during battery charging; this is normal.
