A 10,000mAh cellphone charger will run the GPS on your phone all day. Google maps. Cost $20

That really surprises me. I haven't used my CB since the late 70's.

Seems to be a problem loading pics right now, but got one to load, red wire to ground, black to battery, that's all it takes,
No need to spend big bucks on such a simple issue

Maybe run the black wire to the terminal box so that the load is reflected on the Amp meter?

I stated "black to battery" just to be simple, fact is my connection is aft of the fuse block.
The draw on charging phones, GPS's is so slight I doubt it would read on the meter...but don't let that stop you.
Point is, hooking up a USB phone charger to a Model A is so simple and quick.
Keep in mind if you have a 6V neg or 12V pos system...wire it accordingly
Go for it, you're not going to hurt anything

I have a Garmin GPS with Traffic. The GPS seems to work OK on 6v but the "Traffic" part does not. The "Traffic" works fine in my modern with 12v. I would venture to say that since the charge cord is also the antenna for traffic that has something to do with it.

I'm planning on installing a 12v converter to see if that helps.
