Hello
The device lasts about 8 hours without economy mode, i.e. continuous view of the route. Otherwise around 12h. I bought a small charger for my mobile phone. You won't have any more problems with it. You can attach it to the handlebars

On my device, it's around 6 hours with battery-saving mode, GPS tracking and Bluetooth.

My longest tour was 10 hours.

at least 8 hours (my longest tour)
