2000mA Fast Charging

Offers up to 2A (2000mA) super high charging current to greatly reduce charge time for high capacity batteries.

Portable Power Bank Mode

Take the TN261 on the go and use your own Li-ion batteries to charge your smart phones or other mobile devices (2.1A max output).

Universal Compatibility
with Auto Detection

TN261 is able to charge most common cylindrical rechargeable battery types and sizes in the market. Mix any supported rechargeable battery size and type in the 2 bays and it will automatically detect the charge type.

Ultra High Capacity

3500mAh is the highest capacity currently available for 18650 Li-ion batteries. Compared to other standard 18650 batteries (2000-3000mAh), T35P can provide prolonged runtime in most applications.

High Drain Output

T35P can support up to 8A of continuous current, significantly higher than most other protected 18650 cells, which can only output 3-5A. The extra power ensures steady and reliable performance when operating your devices.

Advanced Protective Circuit

Built-in smart circuit controlled by top quality Japanese Smart IC chip, which offers sophisticated protection against over-charging, over-discharging, overcurrent, and short-circuit. The circuit board’s ultra slim size is also designed to help the battery fit perfectly in your device.
