Frequently Asked Questions

How long does it take to fully charge the AB4000?
The charging time hinges on the charger used. For instance, a 5V/3A charger requires about 5 hours, while a 9V/2A charger takes around 4 hours.

Why is the red error light activated with buzzing noises?
This could indicate that the jump starter is overheating due to too many consecutive jump starts in a short timeframe. Allow it to cool down for about 20 minutes before attempting again.

Is there a risk to my 12V devices with a maximum output of 16.8V?
Generally, most 12V devices can tolerate voltages up to 18V, so your devices should remain unharmed.
