Battery chargers and converters — smart chargers for Li-ion and NiMH, USB chargers and battery spacers.
Smart battery chargers charge rechargeable AA, AAA, 18650, 21700 and other batteries safely, with individual charging slots that monitor each battery separately and stop charging when full. LCD displays show the charge level, voltage and current, which helps you see when batteries are ready and identify weak cells. Some chargers also test battery capacity. Converters and adapters let smaller batteries fit into devices designed for larger sizes, such as AA to C or D adapters. Check the supported battery types and sizes, charging current and safety features before ordering. Chargers with overcharge, short-circuit and reverse-polarity protection are safer for daily use. USB-powered chargers are useful for travel and camping.
Cells: Li-ion batteries.
