    Charge the device for at least 3hours, preferably on a Mains USB charger

    When the device is In use they are designed to be always connected to a power supply
    The Tomtom supplied Power Adapter is rated at 5Volts 1.2Amps
    Even after you have recharged the device externally via a mains charger, when in use in the vehicle, they will still require being connected to a Tomtom supplied Power Adapter (Or a proven suitable 3rd party Power adapter)

    Do NOT attach them to a dashboard USB port in your vehicle as they normally only supply 500mAmp (0.5Amp) and are for data transfer and not supplying power... A dashboard USB port can also fool a NAV4 Device into entering 'Updating Mode' and display the Connected to your Computer splash screen

    Using a NONE Tomtom 3rd party underpowered or a mismatched cigarette lighter adapter/charger can cause a low battery charge problems
