When I first started work (Jimmy Carter was in his first year as President), I drove my predecessor around in a '74 Impala four-door sedan to see our customers; I drove, he directed.
It seems that I've almost always been able to find somewhere again that I drove to originally; if I'm a passenger, no.
Now with a Garmin, Mapquest, and Google Maps, my sense of direction and homing-pigeon "gift" is obsolete.
I want to drive my T around to see customers. I enjoy telling them that as a pump salesman, my car doesn't have any.
Now, I use the Garmin to optimize driving time. Is there a way for the T to keep a Garmin or iPad charged? If not, does anyone know a long-term battery that would keep it working all day?
I have to assume that any small 12 vt. battery, like a riding lawn mower has, would keep it going a heck of a long time. If your car has a battery I'm not sure about how hooking the GPS up to the basically un-regulated T system would affect it but there you go.
This retailer is well known and has a good reputation. A few months ago, I bought an aftermarket replacement battery for my Mac for substantially less than I would have paid for an OEM battery at the Apple store.
Example of back-up/auxiliary Ipad batteries:
Additional suggestions here:
Get one of those battery booster packs with a cigarette lighter outlet on it. Lasts more than a week, and you can use to to boost your regular car batteries
You can use your Garmin on 6 or 12 volt just make a lighter fitting from the parts store and the plug that came with the Garmin and it will work fine, i contacted Garmin a couple of years ago and they gave me that information.
I charge my Garmin Nuvi on 6 volts all the time, seems to work fine.
Yeah, hook you up a lighter plug to 6 volt battery source on car and you are good to go. It'll charge my phone no problem too.
I built at buck transformer to take the 6-8V of the model T and drop it to 5V USB. I can charge anything the uses a USB plug. Unless you look close, most people miss the USB plug mounted on the bottom of the dash in my '27.
I've been using the 6v system in my cars for 5 years to keep my Garmin charged up. Same with the cellphone.
You may want to check with your insurance company so you are covered when using your Model T for business reasons.
You can charge an Apple IPhone on a 6 volt system. You should use a cheap charger for best results. Monoprice has car chargers that work fine. Don't use an Apple charger. Any analog charger will work. Apple chargers are switching style supplies. As said the bats are charged with 5.5 volts.
Do you even need a transformer? I would think a cigarette lighter socket wired to the battery would be simpler and it would work just as well.
Should have said 5 volts.
Be SURE to use the plug that came with your device, they step the voltage down, someone posted that they wired it to 12 volts direct and fried the device.
I am surprised that no one mentioned the little battery chargers that you can put in your shirt pocket. They come with a short cable that you use with the Garmin and the charger. They are no bigger than a small match box. I have two of them that I use with my Garmin. One is an Enercell and the other is a Mophie. I like the Enercell the best and it will keep my Garman going for days. In fact I have never run one down.
