XTAR VC2

XTAR VC2: The Intelligent Li-ion Battery Manager

Know Your Battery’s Real Story.

The XTAR VC2 isn’t just a charger; it’s a diagnostic tool for your batteries. Featuring a unique, tachometer-style LCD display, it gives you real-time insights into your battery’s health, capacity, and charging status. USB-powered and ultra-portable, it’s the perfect companion for your home office or travel kit.

Key Features

• Innovative LCD Display: A high-definition, tachometer-style screen shows you exactly what’s happening. Track your charging current, battery voltage, and charged capacity at a glance.
• Real Capacity Testing: By identifying how much charge the battery actually takes, the VC2 helps you distinguish between high-quality cells and aging or low-quality ones.
• 0V Activation Function: Don’t toss those "dead" batteries just yet. The VC2 can revive many over-discharged batteries, bringing them back to life safely.
• Smart Charging (TC-CC-CV): This three-stage algorithm ensures batteries are charged with precision—prolonging their overall lifespan and ensuring a 100% full charge every time.
• USB Powered Convenience: Use any 5V USB power source—wall adapters, laptops, or power banks—to charge your cells anywhere in the world.

Safety First

We believe a charger should be smart enough to protect itself and you. The VC2 includes:

• Reverse Polarity Protection: If you put the battery in backward, the screen will simply show "Err."
• Short Circuit Protection: Instant cut-off if a fault is detected.
• Heat Dissipation Design: Built with flame-retardant materials and an efficient thermal layout to keep things cool.
• Soft-Start Technology: Prevents sudden current surges that can damage delicate cells.

Broad Compatibility

The VC2 features two independent slots that can handle a wide variety of 3.6V/3.7V Li-ion, IMR, INR, and ICR batteries.

Note: The VC2 is compatible with unprotected 21700 batteries. It may not accommodate some protected 21700 cells due to their increased length.

Technical Specifications

What’s in the Box?

1. XTAR VC2 Charger
2. Micro-USB Cable
3. User Manual

Pro Tip: To reach the maximum 0.5A charging speed for both slots simultaneously, we recommend using a USB wall adapter rated for 5V/2.1A or higher. If your power source is weaker, the VC2 will intelligently lower the current to stay safe!
