GP, the experts in batteries and accumulators, have developed this perfect combination of a lithium-ion charger with a rechargeable 18650 lithium-ion battery. The charger is suitable for battery sizes ranging from 10440 to 26650. The micro-USB input works with any 5V 1A USB power supply. Thanks to the intelligent control of the charging speed, charging with the included micro-USB charging cable is a breeze. A 2600 mAh battery is fully charged in four hours, while a 3350 mAh battery takes no more than five hours. The red LED indicator lights up during the charging process. The charger detects faulty batteries and batteries of the wrong type, causing the red LED indicator to blink. Once the battery is fully charged, the LED turns green.

The included battery is a 18650 lithium-ion battery, also abbreviated as Li-Ion battery. This 3.7 V battery delivers a lot of power and is therefore commonly used in high-performance flashlights, tools, wireless doorbells, gimbals, laser pointers, and other portable electronic devices. In addition to a very high energy density and low self-discharge, lithium-ion batteries do not have a memory effect. This battery is safe to handle, as GP has integrated electronic protection features such as short circuit protection, overcharge protection, deep discharge protection, and over-discharge protection. The packaging includes a micro-USB Li-Ion charger, a micro-USB charging cable, and a GP 2600mAh Li-Ion 18650 battery. Charger suitable for one battery.
