The battery in your VIO device charges when you connect it to any USB socket, for example a computer or USB charger. When connected to a power supply, you can see the battery level when you turn on the device and when you connect and disconnect the USB cable.
Note: Use ONLY the USB cable supplied with your VIO device. Other USB cables may not work.
A low battery symbol is shown on the VIO device when the battery level is low.
On the VIO app, the battery level of your VIO device is shown on the My TomTom VIO screen.
