GO520 battery charger — TomTom Community

GO520 battery charger

Hi everyone,
I wanted to know if is possible to use a QC 3.0 battery charger (18W - 3A) as a power source for my GO520
This is because I would like to replace the cigarette lighter socket on my car with a battery charger with two USB sockets of the quick charge type making the original battery charger unusable.
Thank you

    Hi
    @65Frank
    The Previous NAV4 and Latest (NAV5 WiFi) devices are quite power hungry and can go into "Power saving mode" if not supplied with enough power
    Are you using the Tomtom supplied cable and Tomtom supplied Power Adapter
    The Charger Adaptor and USB Cable supplied by Tomtom WILL run and charge the device at the same time

    Many 3rd party Mismatched Charger Adaptors won't run and charge the device at the same time
    See... It's not simply a power thing.....

    _____________________________________

    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)
    ______________________________________

    (1)... 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: See... Note (1) & (2)

    (2)... Using a NONE Tomtom 3rd party underpowered or a mismatched cigarette lighter charger can cause the device to go into Power Saving Mode: See... Note (1)

    (3)... On the Models with a built-in SIM, the reduction of power to the SIM can cause the dropping of the traffic info: Note (3)

    Note (1)... At an (Undisclosed) percentage of battery discharge, the device will try to save its power requirements by dimming the screen and eventually powers off the device... Devices with a built-in SIM Card may also lose Live Traffic services
    Note (2)... A dashboard USB port can also fool a NAV4 Device into entering 'Updating Mode' and display the Connected to your Computer splash screen
    Note (3)... I tried connecting my Tomtom GO 6200 to my Cars USB port, checked the connection status it reports 'Connected over USB' --> 'GPRS (SIM) Disconnected'

    Stay Safe... ATB YFM

    Hi there 65Frank -
    The replacement QC 3.0 cigarette lighter socket you are considering fitting to your vehicle which supplies 3A from the USB ports will be fine to connect your Go 520 to as long as you use the original TomTom supplied cable.

    Hi YFM,
    I thank you for your detailed and quick answer that I will keep in mind but, in reality, my fear was the opposite and that is if using a battery charger that provided too much current (3A instead of 1.2A) could damage the device.
    Hello and thanks to you too Kieron,
    your answer raises me and certainly yes, I will continue to use the original cable supplied.
    I congratulate you on the support you provide ... well done!
    Thanks so much
