Power your household electronics, gaming controllers, and flashlights sustainably with the Green Lion GRB-13 Rechargeable Battery Dock. This innovative system combines an 8-slot intelligent charger and a secure protective case into one sleek, highly portable design.

Equipped with a USB-C input, the GRB-13 charges up to 4 AA (1970mAh) and 4 AAA (440mAh) Li-ion batteries simultaneously.

Key Features

• Simultaneous 8-Slot Charging: Charge up to 4 AA and 4 AAA batteries at the same time. Features dedicated charging currents optimized for each size (350mA for AA, 200mA for AAA).

• Rapid Charging Speeds: Get back to full power quickly. Fully recharge your AAA batteries in just 1.5 hours and AA batteries in approximately 3.5 hours.

• High-Capacity 1.5V Li-ion Tech: Unlike traditional 1.2V NiMH rechargeable batteries that cause some devices to lag, Green Lion’s advanced Li-ion batteries deliver a constant, stable 1.5V output for peak device performance.

• Smart Battery Detection & Independent Slots: Each slot is monitored individually by an intelligent microcomputer IC. The dock automatically detects non-rechargeable, shorted, or defective batteries, halting power immediately to ensure safety.

• Trickle Charge Protection & Built-In Safeguards: Advanced MCU controls automatically transition to a safe trickle charge once batteries are full. Built-in protocols protect against over-voltage, over-current, short-circuits, and overheating.

• Premium Magnetic Storage Case: Designed for life on the go. The sleek charging dock doubles as a storage container, featuring a secure magnetic closure that keeps your batteries safely in place whether they are on your desk or in your bag.

• Real-Time LED Indicators: Clear, individual LED lights notify you of each battery’s status (Red = Charging, Green = Fully Charged, Flashing Red = Error/Incompatible Battery).
