Xtar VX4 Visible Mixer Set Lithium-ion Battery Charger

The Xtar VX4 is a lithium-ion and NiMH battery charger with a four charging bays that has a charging current of up to 3 A.

The VX4 is suitable for charging the following 3.6 V / 3.7 V lithium-ion and 3.2 V LiFePO4 batteries: 10440 / 14500 / 14650 / 16340 / 17335 / 17500 / 17650 / 18350 / 18490 / 18500 / 18650 / 18700 / 20700 / 22650 / 25500 / 26650 / 32650

The VX4 is also suitable for charging 1.5 V lithium-ion batteries: AAA / AA and 1.2 V NiMH batteries: AAA / AA / A / SC  / C / D.

The VX4 charger features four charging ports and two charging modes, allowing for independent charging in each port. Both modes support the simultaneous charging of three different battery types. The LCD screen displays the battery voltage, charging current, and battery type icon, and it indicates when the battery is fully charged.

Standard charging mode supports 3.6 / 3.7 V lithium-ion, 1.5 V lithium-ion, and 1.2 V NiMH batteries. LiFePO4 charging mode supports 3.2 V LiFePO4, 1.5 V lithium-ion, and 1.2 V NiMH batteries. To switch between Standard Charging mode and LiFePO4 Charging mode, long press the C/V button on the front left of the VX4. Connect the charger to a suitable power source and insert the batteries to automatically begin charging. The charger will automatically detect the battery type and select the appropriate charging current.

The VX4 features a capacity measuring function that helps assess your battery's capacity and evaluate its overall health. In Standard Capacity measuring mode, a flickering NiMH or 1.5 V Li-ion icon indicates a battery is being identified or activated. A solid 3.6 V Li-ion, 1.5 V Li-ion, or NiMH icon plus "CHG" indicates the battery is charging. In LiFePO4 Capacity measuring mode, a flickering NiMH or 1.5 V Li-ion icon indicates a battery is being identified or activated. A solid LiFePO4, 1.5 V Li-ion, or NiMH icon plus "CHG" indicates the battery is charging. When complete, the display will show "done" in both functions. Real time voltage and charged capacity is not available when charging 1.5 V Li-ions.

Press the C/V button once to switch between different charging current levels. During charging, press the MODE button to toggle between displaying the real-time charging current and the charged capacity. To switch between charging and capacity measuring functions, hold the MODE button down. In LiFePO4 charging mode, holding the MODE button will activate the capacity measuring function.

During the discharging process of 1.5 V Li-ion batteries in the capacity measuring function, press the button on the right to switch the display between mWh and mAh. Long press the button to turn off the backlight.

The VX4 allows for manual selection of the charging current when using the included PDW20 adaptor, from 0.25 A to 3 A. Simply connect to the USB-C port on the top of the charger.

The display above the batteries will show the charge level of each individual battery as well as the real-time voltage and real-time current.

When the charger is inactive with no batteries inserted, the LCD screen will automatically dim to save energy.

Note: Always use in accordance with instruction manual and read before first use.
