TomTom Runner 3 power charging
I have always charged my tomtom runner 3 using the connecting cable to the computer while doing the sybc. This summer, being away from home, for the first time ever I tried to charge it from the electricity socket: it starts charging and them, all of a sudden, after 10-15 seconds, it doesn't anymore and the time shows up again. I tried also to charge from a USB charger and again the same thing. Luckily I managed to charge it from a mobile phone using a little usb converted I happened to have. Is this normal or is it a defect of the watch?
