Need new Sat Nav car charger

judexx

The car charger for my (cheap 'MyGuide') sat nav has broken.

The input to the sat nav is mini USB; the lead is marked 'Input 12v - 24v 1.3amp'; 'Output 5v 1.5 amp'. Are these chargers generic ? and would this one be ok ?

Edit . No it's micro USB. But the picture looks like mini USB. Hmmm...

A generic charger will work. It's Volts that matter, not amps.

That's not correct, though, is it? Both matter, if the charger cannot supply sufficient current at a safe voltage for the device, it will not be able to provide the power required to charge or power the device.

For a small device like a satnav 1.5A should be sufficient. I would expect 1A to be fine too. If you have the old charge look for the A or ma listed on the device and make sure the new one has the same or more.
Voltage is the same for all USB 5V

Captain pedantic. Most sat navs draw about 300ma to run with no charging. If you can find me a Micro USB charger with less than 500ma output then you can have a free cookie.

Just buy a charger, and use it, you'll be fine.

It's not about being pedantic, it's about being accurate.:p

But in the interest of helping people, it's absolutely unhelpful. For one, Micro USB is a standard of 500ma, so you'll almost certainly never find a charger less, and like I said, most sat navs use 300ma.

Which is pretty irrelevant, since the OP asked about mini-USB chargers.


I can't find detailed specifications relating to power usage for the myGuide unit detailed by the OP, and making assumptions isn't that helpful either.

Regardless, the specification for USB is 500ma. Google it.

I personally wouldn't buy that as it's going to be cheap and nasty carp.


You can buy a decent quality generic charger at most mobile phone / electrical shops. Bring your sat nav with you so you get the right one. Many come with both adaptors in any case
