Replenish the power in your single-cylinder lithium or NiMH batteries via this Universal Magnetic USB Charger from Olight. It offers a maximum charging current of 750mAh and is compatible with all 3.6 - 3.7V cylindrical lithium cells, including li-ion and lithium-manganese (IMR), as well as virtually all cylindrical NiMH cells.
The charger works with batteries of any size and rejuvenates one at a time, connecting to both ends of the cell via dual magnetic end caps. There's no need to worry about the orientation of the cells, as the charger automatically detects polarity. It also recognizes battery chemistry. At the opposite end of the cable from the magnetic caps is a USB-A connector for insertion into an AC wall adapter or portable power bank. The cable resembles a headphone cord and features a flat, tangle-free design that allows for easy use and storage.
