Frequently Asked Questions - VT3503 V-TAC

How to check the remaining battery level?

Briefly press the control button: the 4 LEDs indicate the level: 4 LEDs = 75-100%, 3 LEDs = 50-75%, 2 LEDs = 25-50%, 1 LED = less than 25%.

How to recharge the portable battery?

Plug the provided Micro USB cable into the power bank input, then the other end into a USB power adapter (5V/2A recommended) or a computer USB port. Charging starts automatically.

How long does it take to fully charge the power bank?

The first charge or after long inactivity may take 8 to 10 hours. Subsequent charges are faster, about 2 to 3 hours with a 2A charger.

Can I charge two devices at the same time?

Yes, the VT3503 has two USB output ports, each delivering 5V/2.1A. You can charge two devices simultaneously.

Which devices are compatible?

All devices that charge via USB: smartphones, tablets, headphones, speakers, portable consoles, etc. The standard 5V output works with most devices.

How to use the built-in flashlight?

Is it safe to leave the power bank charging overnight?

Yes, the power bank has overcharge protection. Once the battery is full, charging stops automatically.

Why is the nominal output capacity lower than the battery capacity?

Due to conversion losses (heat, voltage), the actually available capacity is about 65% of the battery capacity. For the VT3503, 5000 mAh gives about 3250 mAh output.

Can I carry this power bank on a plane?

Yes, power banks of 5000 mAh (less than 100 Wh) are allowed in cabin. Check your airline's rules.
