Product Description
The XTAR VC2L is a highly capable, redesigned 2-slot smart battery charger that bridges the gap between compact size and upgraded performance. Featuring a vibrant color VA LCD display with an innovative gauge-style interface, it provides clear real-time data on battery voltage, charging current, and charged capacity. The VC2L utilizes an upgraded extendable spring-loaded slot design, specifically engineered to safely accommodate protected 20700 and 21700 batteries—a significant advantage over many standard chargers. With a USB Type-C input, adjustable 2A single-slot fast charging, and intelligent 0V activation, this charger delivers a professional, reliable, and highly compatible charging experience for all your Li-ion and Ni-MH batteries.
Key Features
-
Upgraded Extendable Battery Slots: Features a newly designed spring-loaded bay that securely accommodates a wide range of sizes, including protected 20700 and 21700 batteries, alongside standard 18650 and other cylindrical cells.
-
Innovative Color VA LCD Display: Equipped with a high-contrast color screen using a creative gauge-style interface. It clearly displays real-time battery voltage, charging current gear, charged capacity (mAh), and battery type (Li-ion or Ni-MH).
-
2A Single-Slot Fast Charging: Supports adjustable charging currents: 2A for a single slot, 1A for two slots simultaneously, or 0.5A for two slots simultaneously. This allows you to quickly power up high-capacity batteries.
-
Smart Type-C Input: Features a modern USB Type-C port (5V 2.1A), allowing for effortless power connection using standard phone adapters, laptops, power banks, or car chargers.
-
Intelligent Charging Algorithms & 0V Activation: Automatically identifies battery types and applies optimized charging strategies: TC-CC-CV (Trickle-CC-CV) for Li-ion batteries, and precise 0ΔV / -ΔV pulse charging for Ni-MH/Ni-CD batteries. Built-in 0V activation safely revives over-discharged batteries.
-
Comprehensive Safety Protection: Built-in over-current, over-voltage, over-charge, short-circuit, and reverse polarity protection (the screen displays "Err" upon reversal). Intelligent temperature control ensures a safe and stable charging process.

Frequently Asked Questions (FAQ)
Q1: Can the XTAR VC2L charge protected 20700 and 21700 batteries?
A1: Yes. This is one of the VC2L's key upgrades. It features a re-engineered extendable spring-loaded slot specifically designed to safely accommodate protected 20700 and 21700 batteries.
Q2: What is the maximum charging current of the VC2L?
A2: The VC2L offers three adjustable charging currents: 2A for a single slot (2Ax1), 1A for two slots simultaneously (1Ax2), and 0.5A for two slots simultaneously (0.5Ax2). You can switch between modes by clicking the button below the screen.
Q3: What does the color VA LCD display show?
A3: The innovative gauge-style display provides real-time, easy-to-read information including battery voltage, charging current gear, charged capacity (mAh), and battery type. If a battery is inserted incorrectly, the screen will clearly display "Err".
Q4: How does the 0V activation feature work?
A4: If a lithium battery has been over-discharged to an extremely low voltage (near 0V), the VC2L will automatically detect it and apply a safe, low current to gently reactivate the battery's protection circuit, often successfully restoring it to a usable state.
Q5: Can I charge a Li-ion and a Ni-MH battery at the same time?
A5: Yes. The VC2L features two completely independent charging circuits. You can safely charge a 3.6V/3.7V Li-ion battery in one slot and a 1.2V Ni-MH battery in the other slot simultaneously.
