I use my GPS for work.And change vehicles a lot.Need an adapter or external power supply.That does not run thru cigarette lighter.Have tried Best Buy,Radio Shack not having much luck.My device is a Garmin Nuvi.The antenna and power supply is one intergrated cable.Thanks..
If you have only one cigarette lighter/12v power source, have you considered a power inverter?
~ Do not go where the path may lead, go instead where there is no path and leave a trail.
~ Ralph Waldo Emerson ~12 volts is 12 volts. Any 12 volt power source with a car adapter will work. You could cobble one together with AA holders and a lighter plug receptacle from Radio Shack for next to nothing.
I would probably do it with Anderson Powerpole connectors and get a nice flat rechargeable that fit on the back of the unit and have a connector for a car 12 volt plug to charge the battery pack.
You would have to look up how the antenna works if it s in the power cord, but that should not be to difficult.

A lot of the newer ones use USB. It might be possible to just run it off a USB battery pack with an adequate output.

Are you sure that the power cable is also the antenna for the GPS? On most of the new Garmins, that power cable is also the receiver for the live traffic data. If you don’t care about the live traffic data, you can ditch that cable and use any mini usb cable based power cord. This open up a lot of option with all of the extended battery solutions intended for phones and tablets.
You said it can’t run through the cigarette lighter — is that because something else is already using it? If so, there are multiple outlet 12V adapters out there for cheap.
Like Stonerman33 said, if it’s a USB connection for powering the GPS, you can find lots of portable battery packs that power a USB port.
cigarette lighter power port is out of service.It is an older truck.Yes I did check the fuse.I am going to need an external battery pack.This is kind of a mixed blessing miss the old days of map books,paper maps.But they are out dated as soon as you buy them.I have an iPhone 5 and use Google maps.But still want to use the GPS.For various reasons.Thanks for all the help.
