Product Information

Full details

The Xtar VC4SL is an ideal companion for photography enthusiasts, vapers, and flashlight users who rely on multiple battery types, offering rapid charging and real-time status monitoring in one versatile unit. Its standout benefit is the USB Type-C QC 3.0 fast charging capability that significantly reduces downtime for high-capacity cells. A notable caveat is that the package does not include a power adapter, requiring users to supply their own wall plug that supports Quick Charge specifications to achieve maximum speed.

FAQs

Does this charger include batteries?

No, the Xtar VC4SL does not include any batteries; these must be purchased separately.

Can I charge different battery types at the same time?

Yes, each of the four slots is independent and can charge different chemistries, sizes, and capacities simultaneously.

What happens if I use a non-QC adapter?

The charger will still work, but it will automatically scale down the charging speed to remain compatible with the power provided by the adapter.

Is the LCD display always on?

The display provides real-time information while charging. It can be toggled to show different metrics for each battery slot.

Can it charge 21700 protected cells?

Yes, the sliding slots are designed to accommodate a wide variety of sizes, including longer protected 21700 batteries.

Does it have a 0V activation function?

Yes, the VC4SL can attempt to revive over-discharged batteries that have a voltage of 0V, provided they are not physically damaged.

Troubleshooting

The LCD screen is blank when batteries are inserted.

Ensure the USB-C cable is fully seated and that the power supply provides sufficient voltage (QC 3.0 recommended).

Batteries are charging slower than expected.

Verify that your wall adapter supports QC 3.0 protocol; standard 5V/1A adapters will limit charging speed.

Charger indicates 'Err' or displays no charge progress.

Remove the battery and clean the metal contacts on both the battery and the charger bay. Ensure the battery is not damaged or internally shorted.
