Product Information
Full details
The XTAR VC4 is a versatile, USB-powered battery charger designed for users who need a reliable, all-in-one solution for both Li-Ion 3.7V and Ni-MH 1.5V household batteries. Its primary benefit is the integrated LCD screen that provides real-time monitoring of charging progress, capacity, and voltage levels, helping you maintain battery health; however, it does require an external 5V/2.1A USB power source, which is not included.

FAQs
Does the VC4 come with a wall plug?
No, the package includes the charger and a USB cable, but you must provide your own 5V/2.1A USB wall adapter.
Can I charge different battery types at the same time?
Yes, the VC4 has four independent slots that can charge different sizes and types of Li-Ion and Ni-MH batteries simultaneously.
What happens if I put a battery in backward?
The charger is designed with reverse-polarity protection to prevent damage to the device and your batteries.
Can I charge 1.2V Ni-MH rechargeable batteries?
Yes, the charger is compatible with 1.5V Ni-MH chemistry, which includes standard 1.2V rechargeable AA and AAA batteries.
How do I know when the battery is finished charging?
The LCD display will indicate when a slot has finished the charging cycle by showing the full capacity and stopping the voltage increment.
Is it safe to leave batteries in the charger after they are full?
While the charger is designed to be safe, it is recommended to remove batteries once they reach full capacity to prolong their overall lifespan.
Troubleshooting
LCD screen is blank or does not light up
Verify that your USB power source provides at least 2.1A and that the cable is firmly seated in both the charger and the wall adapter.
Batteries are not charging
Check that the batteries are properly seated in the slots and aligned with the correct polarity. Ensure the battery chemistry is compatible with the charger.
Charging process seems slower than usual
Ensure you are using a power adapter that meets the 2.1A input requirement; using a low-amperage port (like a standard computer USB 2.0 port) will limit charging speed.

Setup, Compatibility & Care
To set up the VC4, simply connect the provided USB cable to a power adapter capable of 5V/2.1A output and plug the other end into the charger. Insert your batteries according to the polarity markings in each slot.
Compatibility Note: This device is strictly designed for 3.7V Li-Ion and 1.5V Ni-MH batteries. Do not attempt to insert non-rechargeable alkaline batteries or other chemical types not specified.
Care Instructions: Keep the charger in a dry, ventilated environment with an operating temperature between 0 °C and 40 °C. Periodically wipe the gold-plated contact points with a dry, clean cloth to ensure proper electrical conductivity and remove any dust accumulation.
