XTAR VX4 V2 SET 4-Bay Smart Battery Charger for Li-ion 3.7V and Ni-MH/Ni-CD 1.2V with LCD, USB-C QC3.0, Power Bank Function

The XTAR VX4 V2 SET redefines versatility in battery charging by combining four independent slots with automatic chemistry detection for both 3.7V Li-ion and 1.2V Ni-MH/Ni-CD cells. Unlike single-chemistry chargers, it adapts to your entire battery collection, from tiny AAAA to massive 26700, while providing real-time diagnostics on a multi-functional LCD. The included USB-C cable and QC3.0 input ensure fast, efficient charging, and the built-in USB-A output transforms the charger into a power bank for emergency device top-ups.

• USB-A output (5V 2A) enables power bank functionality
• Advanced safety: over-charge, over-discharge, short-circuit, reverse polarity, and temperature protection
• 0V activation function revives over-discharged batteries
• Internal resistance test for battery health assessment
• Flame-retardant ABS housing for durability and safety
• Set includes USB-C cable and user manual

In daily use

Place your batteries in any of the four bays and the VX4 V2 automatically identifies the chemistry and selects the optimal charging parameters. The clear LCD keeps you informed of voltage, current, capacity, and internal resistance, so you always know the health of your cells. When you're on the go, connect a device to the USB-A port and use the charger as a power bank, drawing from the batteries inside. The 0V activation feature can even rescue deeply discharged batteries that other chargers reject.
