Product Description
The XTAR VC4H is a high-performance upgraded 4-slot smart battery charger designed for both 3.6V/3.7V Li-ion and 1.2V Ni-MH/Ni-CD batteries. Equipped with a modern QC3.0 Type-C input, it delivers a fast 2A charging current for two slots simultaneously or 1A for all four slots. Unlike previous models, the VC4H features an extended slot design that specifically supports protected 20700 and 21700 batteries. The intuitive LCD gauge screen provides real-time visibility of battery voltage, current, charged capacity (mAh), battery type, and channel information. With advanced 0V activation, intelligent TC-CC-CV and pulse charging algorithms, and comprehensive safety protections, the XTAR VC4H is an ideal, practical, and upgraded charging station for your diverse battery collections.
Key Features
-
Upgraded Extended Slots: Specifically designed to safely accommodate and charge protected 20700 and 21700 batteries, offering superior versatility over standard chargers.
-
Intelligent LCD Gauge Display: The clear, innovative screen displays essential real-time data, including battery voltage, charging current gear, charged capacity (mAh), battery type (Li-ion or Ni-MH), and slot number.
-
QC3.0 Fast Type-C Input: Features a universal Type-C port supporting QC3.0 protocols (5V/3A, 9V/2A). Allows for efficient charging with a 2A current for 2 slots simultaneously (2Ax2) or 1A for all 4 slots (1Ax4) for Li-ion batteries.
-
Smart Charging Algorithms: Automatically identifies battery types and applies the optimal charging strategy: Unique TC-CC-CV (Trickle-CC-CV) for Li-ion batteries, and precise pulse charging with 0ΔV and -ΔV cut-off detection for Ni-MH/Ni-CD batteries to ensure a full charge and protect battery lifespan.
-
0V Activation Technology: Built-in 0V activation safely revives and recovers over-discharged lithium batteries, giving new life to depleted cells.
-
Intuitive LED Status Lights: Features clear red/green LED indicators. Red light indicates active charging, self-testing, or activation. Green light indicates standby, fully charged, or reverse polarity protection (please correct immediately).
-
One-Button Operation & Convenience: Use the "Curr." button to manually switch charging currents. Use the "Mode" button to cycle through slot information on the LCD. Press and hold either button for 1.5 seconds to turn off the screen backlight.
-
Comprehensive Safety Protections: Built-in overcharge, overcurrent, overvoltage, short-circuit, and reverse polarity protection, supported by an intelligent temperature control system for stable and safe charging.

Frequently Asked Questions (FAQ)
Q1: What is included in the package?
A1: The package includes 1x XTAR VC4H Smart Charger, 1x Type-C Charging Cable, 1x User Manual, and 1x Protective Storage Pouch. (Batteries are not included).
Q2: Can the VC4H charge protected 20700 and 21700 batteries?
A2: Yes. This is a major upgrade of the VC4H. It is specifically designed with extended slots to safely accommodate protected 20700 and 21700 batteries, unlike many other compact chargers.
Q3: What is the maximum charging current of the VC4H?
A3: For Li-ion batteries, the VC4H supports up to a 2A current for a single slot, 2A for two slots simultaneously, or 1A for all four slots simultaneously. For Ni-MH batteries, it supports up to 1A.
Q4: What do the LED indicator lights mean?
A4: Red light indicates the battery is charging, undergoing self-testing, or being activated. Green light indicates the charger is in standby mode, the battery is fully charged, or the battery is inserted with reversed polarity. If the light is green and the battery is not full, please check the battery direction.
Q5: How do I turn off the screen backlight?
