XTAR VC4 is not only the improved version of both VC2 and XP4 chargers, but also the combination of the principle of technological advancement and responsibility for safety and environmental protection. The XTAR VC4 is a professional Li-Ion/NIMH battery charger with four independently functioning charging bays to operate from any 5V USB port.
Xtar VC4 Charger for Li-Ion and NIMH batteries + USB cable
Compatible with all USB mains and car adapters, input voltage is intelligently identified and adjusted. Power supply unit not included;The VC4 can detect, display and charge Ni-MH and Li-Ion batteries at the same time. The large display shows: charging current, battery voltage, battery type and the charged capacity in mAh of all battery compartments.
The charging speed (charging current) of the batteries depends on the USB power supply. It is possible to select a weaker USB power supply, but charging of the batteries is no longer possible at full current. Charging with a low power supply offers advantages for small batteries that can be charged with a low current. Charging large batteries is thus prolonged.
Suitable power supply unit to make full use of the charging current: Item number: 400609 USB 230V adapter 5V 2100mA Universal AC USB power supply unit.
