Made by Nitecore, one of the names in battery charging, this charger has four spring loaded slots to ensure it can manage a range of battery sizes and forms, including Li-ion (10440, 14500, 16340, 17670, 18350, 18500, 18650, 22650, etc.) and Ni-Cd / Ni-Mh (A, AA, AAA). The microcircuit inside identifies the battery chemistry, e.g. ICR, IMR and automatically adjusts the output to match.
A large LCD shows the charging status of each battery, including voltage, time charging and milliamps, allowing you to keep updated on how they are performing. On the back it has a DC 12V input and 110V/240V AC figure of 8 input. It comes supplied with a UK mains plug lead (also in black) so that you have everything you need to start using it.
