The top of the VC series. At the request of many customers, the already well-equipped VC4S has been supplemented with manual charging current settings and support for electronically protected 20700/21700 batteries. The charger is suitable for beginners as well as advanced users who want to know more about their batteries than just "full" or "empty".

Professional Li-ion/NIMH battery charger with USB-C QC3.0 input.

XTAR stands in the combination of the principle of technological progress and responsibility for safety and environmental protection. 
With four independently functioning charging bays, for operation on any 5V USB port or to achieve full power, connect to a Quick Charge USB power adapter (400613).
Determine actual capacity, charge or discharge batteries to storage voltage (rated voltage) to conserve batteries during extended storage, manual charge current setting (optional) or built-in QC processor to achieve full 4A total output (only with a Quick Charge USB power supply).nbsp;(only with QC USB power supply) are the most important additions to the already very successful VC4 and VC4S charger besides the newly revised housing with support of 20700/21700.
Compatible with all USB mains and car adapters, input voltage and charging current is intelligently identified and adjusted. Power supply not included. (suitable QC USB power supply unit 400613, 400622)
The XTAR VC4SL can detect, display and charge Ni-MH and Li-Ion batteries simultaneously. The large, clear display shows: charging current, battery voltage, internal resistance, battery type, charged or discharged capacity in mAh of all battery compartments according to the set cycle.

The following Li-Ion battery types can be charged:

10440 / 14500 / 14650 / 16340 /  17335 / 17500 / 17670 / 18350 / 18490 / 18500 / 18650 / 18700 / 20700 / 21700.
The following batteries can only be charged in slot 1 and slot 4: 25500 / 26650 / 26700 / 32650 
3.6V/3.7V lithium-ion batteries.
Also suitable for protected 20700/21700 batteries. max. length 77.5 mm.

The following Ni/MH Ni/CD battery types can be charged: 

The following batteries can only be charged in slot 1 and slot 4:  SC / C / D

Technical information and notes

The charging speed (charging current) of the batteries depends on the USB power supply. It is possible to select a weaker USB power supply, however, charging of the batteries is no longer possible at full current.
Suitable power supply unit to make full use of the charging current: Item number: 400613 FLYPOWER EP-18WQC3 Quick Charge, 400613 XTAR QC3.0 18W

Idle power consumption at 5V is approximately 200 mA when the display is bright 64 mA when the display is dimmed and 47 mA when the display is off.
At 0V, the charger reports "Err".
Above 0V, the charger estimates Ni/MH batteries and starts charging. This estimation is changed to Li-Ion as soon as the battery voltage reaches Li-Ion values.
Below 1.8 V, the charger assumes Ni/MH.
Above 1.8 V, the charger assumes Li-Ion.
After a power failure or insertion of the battery, charging will continue.
When the unit is not connected to the power supply, approx. 1 mA is consumed by a Li-Ion and 0.1 A by a Ni/MH battery.
The current dial shows the maximum possible charging current, not the actual charging current. Use the "Cur" display for this purpose.
The mAh display flashes "Full" when the corresponding battery is full and the LED is green.
