Cigarette lighter to USB adaptors

[Paul Croft]

I have two TomTom adaptors to power my TomTom from the cigarette lighter, one with one power take off and the other with two (see photo attached), and neither works. I've bought a dual take off adaptor from ebay and that works as expected so can anyone throw any light on why the TomTom adaptors may be unserviceable. I don't know how long I've had them and assume at least one worked at some time but I've not needed one for a few years now and only went looking for one (in my drawer of bits and bobs!) when I bought a new car and figured this was the best way to power my GO 610 in this instance. Are they historically unreliable or is there an on/off switch I'm missing? I can't believe I'd ever have kept two defunct adaptors, I normally throw a broken thing away, so I assume they worked at some time.

Haven't ever lost one to failure (yet). A couple of cables, yes, but not an adapter.
Have you checked the fuses in both?
What are the current ratings shown on them, if any?
Still using your GO 610?

Perhaps this sounds silly but how do I test the fuses? I can see no way to access them, the units are completely sealed as far as I can tell.

The single output adapter shows: input 12/24V 1A , output 5V 1.2A, fuse 32V 1.5A
the double output adapter shows: input 12/24V 2.9A , output 5V 4.8A, 2.4A, each output 2.4A

The two units are the same as available from TomTom here: https://www.tomtom.com/en_gb/sat-nav/accessories/ so I've obviously bought them from TomTom at some time but don't remember when and have no receipt for either :-(

I misinformed re the GO 610, that was a previous one I had and it was a GO 6100 , I'm now using a GO Premium X, principally because I needed the bigger memory.

I've now established the single charger came with the GO 6100 and the twin charger came with the GO Premium X, I'd just never used them because my cars have had USB sockets.

After going slowly mad navigating the TomTom support site I have determined that the dual port charger is under warranty because it was bought less than two years ago. I have the purchase order number and the legal guff tells me to contact support to obtain a warranty claim number but every lead I try and follow on the support site just sends me back to the warranty terms page. Can anyone on this forum give me a link to a department which handles warranty claims please?

I guess one could ask whether the 2.4A charger works with other USB powered devices. Might be good to check.

The single adapter (1.2A) is as low as you would want to go for a 6100 if attempting to both charge and operate the device. Thought that have been for the 610 (no cellular).

The dual adapter (2.4A) should work fine if it's really working.

 

[Paul Croft]

That was my first thought but I eliminated that, the phone doesn't charge when connected via the adaptor and cable but it does when plugged straight into an adjacent USB port in the car. Also tried the adaptor in a known working cigarette lighter socket and nothing. Finally tried a known functioning adaptor in the car's cigarette lighter and everything works, it's definitely the TomTom adaptor that's u/s. There appears to be a small 'light' on it which I guess illuminates if power is available but there's no light visible. Good to know that the single adaptor is not powerful enough to charge and run the TomTom so I'll bin that.
Finally, have you any idea how I might go about getting a replacement adaptor from TomTom? I cannot find any way to successfully navigate the support page and claim a warranty replacement. If you are in any way able to provide a link to a functioning department or person who handles these matters I'd be most grateful.
Thanks for your input thus far,
Cheers
Paul

No idea how it's managed in the UK. dhn may have a clue and may pipe in here to let us know.
Just out of curiosity, is your dual unit held together with a couple of screws on the side we don't see in the photo?

I wish! Best guess is it’s glued, it’s certainly not obviously repairable
