Supporting almost all battery types, the ISDT C4 is a high-performance, portable, smart charger for your cylindrical cells.
The charger is perfect for recharging popular batteries like 18650 cells, regular AA's and AAA batteries. Its battery bay has a clever design making it compatible with batteries of different sizes in designated ports, for example 18650 cells (x2), AA's (x4) or AAA batteries (x2). The charge slots are independent, so you can charge batteries of different types at the same time if space allows. The charger has plenty of power to recharge batteries quickly; it supports up to 3A per channel, with a max 8A overall output.
The C4 has various charge modes and there's even an auto mode that will identify the battery type and match with the appropriate charging strength (please double check auto-selected settings are appropriate for your battery). The charger is really easy to use thanks to its clear 2.4 inch IPS LCD display, touch sensitive buttons and intuitive menus. While operating it provides lots of useful information including: voltage (displayed numerically and graphically), charge current, temperature, charge time and internal resistance. Internal resistance is a useful measurement as it can be used to access the health of your batteries.
Please note iSDT supply this charger with a EU power plug as standard, but we are including a UK plug, so no adapter will be required.
