USB 18650 Battery Charger Quad Bay With LED Indicators

Charge up to four 3.7V lithium-ion cells simultaneously from a single USB power source with this compact, blue ABS charger. Each bay operates independently, so you can drop in batteries as you need and monitor progress at a glance with dedicated LED indicators.

Smart protection for safer charging

• Overcharge protection to prevent battery degradation
• Overheat protection to guard against elevated temperatures
• Overvoltage protection for added safety during power fluctuations
• Overcurrent protection to minimize stress on each cell

Clear status, individual bays

One LED per installed battery provides immediate feedback: red means charging is in progress, green indicates a full charge. The system automatically identifies and handles charging for each cell, so you know which batteries are ready without removing them.

Wide compatibility and fast charging

Supports a broad range of common 3.7V Li-ion cells, including 10440, 14500, 16340, 16650, 14650, 18350, 18500, and 18650. Input is standard DC 5V from a USB source, with per-bay output of 4.2V at up to 1000mA, enabling swift top-ups for devices with low power draw like flashlights, headlamps, and lanterns.

Design and usage notes

The blue ABS chassis combines lightweight durability with everyday practicality. This charger is intended for normal working environments and is ideal for keeping multiple devices ready to go without juggling several chargers.
