Goodmorning everyone,
I guess I got a rip off by buying a battery charger that gave for 5V and 3A at the output. I believe my device has gone into power saving mode.
What can I do?
Thank you

Hi @65Frank
There have been instances of 3rd Party chargers not giving what you are lead to believe and causing the Tomtom units to go into Power saving mode as a result.
If you have a Apple or equivalent Phone charger plug that takes the USB cable you can give the unit a good charge up with that and it should return to normal. The recommendation is to use the Tomtom original charger as that is designed to give you the required output that will not only run the unit but also charge it up as well at the same time.
The genuine chargers are readily available.

The third party charger may be able to give out what it claims but it has to signal to the TomTom that it is a higher power charger. Some chargers don't do that and some devices take what chargers can give regardless, but the TomTom does require the high-power signaling to keep it from going into low power mode.
That said, 3A seems unusually high output since standard USB chargers are usually limited to 10 watts or so. Any chance that charger has 3 ports, 1A each?1 -
Yes, I have noticed the consequences of using an unsuitable battery charger. The one I bought has 2 USB ports and each should provide 3A (so it was written).
Anyway, following Doug's advice, the problem is solved for now.
Thank you for your invaluable assistance.

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
