charging a sat-nav using 24v

[nightrunner]

this may sound like a silly question but i have heard so many answers to this question, is it possible to plug in and charge a sat-nav using a commercial vehicle bearing in mind that all commercial vehicles are 24v and the sat-nav is 12v and only designed for cars, any replies would be most appreiciated, thanks

Have a look at the label on the charger, to see what voltage it is for.

I don't use satnav, but my phone charger says 12/24v so I can charge my phone from the cig lighter in my car and my lorry.

Also a lot of HGV's have a dedicated 12V socket, so you might be able to use that, but don't be tempted to 'try' until you know for certain, as 24V will cook a 12V Sat Nav to a turn!

a dc -dc converter will solve your problem.

available from truck stops and some garages for about a tenner plugs in and drops the 24v down to 12v.

another way of doing it is using an inverter these are available in 12 or 24v versions a little more expensive at around 20-25 quid

plug in and increase your 24v to 240v this means you can use your mains chargers instead.

hope this helps

depends what

No mdoo, a lorry runs at 24v so the cigarette lighter is 24v.

As sddsdean says, some HGVs have 12v sockets aswell, but the may be a smaller socket requiring a different plug.

I emailed tom tom myself about the same query they told me it would be ok on 12v or 24v. I have been using my tom tom 1 for over a year plugging into 24v and it works just fine

I believe that all truck radios are 12 volt, so up above the drivers head 12 volt is usually available.
