XTAR VX4 V2: The True 4-in-1 Hybrid Charger
The XTAR VX4 V2 (often hailed as the "Visis" edition) is the ultimate problem-solver for anyone who owns a drawer full of different battery types. While most chargers claim to be "universal," the VX4 V2 actually lives up to the name by adding dedicated support for the new industry-standard 1.5V Li-ion cells.
One Charger to Rule Every Chemistry.
Think of the VX4 V2 as the "Swiss Army Knife" of power management. It doesn’t just charge batteries; it analyzes, revives, and optimizes them. Whether you are using traditional Ni-MH AAs, high-performance 18650s, stable LiFePO4 cells, or the latest 1.5V Li-ion rechargeables, the VX4 V2 handles them all in one go—no separate chargers required.
Why the VX4 V2 Stands Out
- The 1.5V Li-ion Specialist: Most "universal" chargers treat 1.5V Li-ion batteries like standard Ni-MH, which leads to incomplete charges. The VX4 V2 uses a dedicated charging protocol to ensure these cells reach their full potential safely.
- Grading Mode (Capacity Testing): Stop wondering which batteries are "duds." In Grading mode, the charger performs a full charge-discharge-charge cycle to show you the real capacity ($mAh$ or $mWh$) of your cells.
- USB-C PD 3.0 & QC 3.0 Input: No more bulky proprietary power bricks. Plug into any modern USB-C fast charger to unlock maximum speeds across all four slots.
- Adjustable Current (2.0A Max): You’re in the driver’s seat. Manually select between 0.25A, 0.5A, 1.0A, or 2.0A to prioritize either battery longevity or high-speed turnaround.
- Dual-Unit Display: View your battery’s energy in both Capacity ($mAh$) and Energy ($mWh$)—a must-have feature for accurately measuring 1.5V Li-ion performance.
Universal Compatibility
The VX4 V2 features extra-long independent slots (fitting batteries from 30mm to 75mm), making it compatible with almost everything on your shelf.

Safety & Intelligence
- Intelligent Identification: The VX4 V2 automatically detects battery chemistry and applies the optimal charging algorithm.
- Internal Resistance (IR) Testing: Measures the "health" of your battery. High resistance? It might be time to recycle that cell.
- 0V Activation: Revives over-discharged Li-ion batteries that other chargers would ignore.
- Multiple Protections: Over-charge, over-discharge, short circuit, and reverse polarity protection come standard.

Meta Title & Description
Meta Title:
XTAR VX4 V2 Charger | 4-in-1 Smart LCD Tester for 1.5V Li-ion & LiFePO4
Meta Description:
The XTAR VX4 V2 is the ultimate 4-bay charger for 1.5V Li-ion, 3.7V Li-ion, Ni-MH, and LiFePO4 batteries. Features Grading Mode, IR testing, and USB-C PD fast charging.
Expert Tip: If you're using this for photography or high-end electronics, pay attention to the mWh reading during Grading mode. For 1.5V Li-ion batteries, milliwatt-hours ($mWh$) provide a much more accurate picture of total energy than standard $mAh$!
