No, it will charge while being powered by the car's power source. On battery power alone it will last up to 2 hours. ^DK
Sorry, there was a problem. Please try again later.No - that is how long the battery will last when not connected to the car. Drove for over 10 hours with it plugged in - it is charging the battery as you drive
Sorry, there was a problem. Please try again later.No. As long as it is plugged into the car outlet, it will remain charged. But don't leave it plugged in when not driving. Could drain your car battery.
Sorry, there was a problem. Please try again later.When the unit is plugged into the power port (cigarette lighter) in your car, it is charging and running from the power source, not the battery. When you unplug it, the unit will turn off in 30 seconds unless you tell it otherwise.
