Cell phone charging
 

I followed Paul Shinn's video about installing a cell phone charger using a unit from Amazon https://www.amazon.com/dp/B0D4YSHSH3...sin_title&th=1. It is described as a 12V cigarette lighter and power outlet, and says it comes with a 10 amp fuse, but this is the one that came with it. As nearly as I can decipher this is a 3 amp fuse. The symbol before the numeral 3 appears to be something that didn't stamp completely in the factory, but that is what it looks like. I have this connected to the ammeter and grounded in common with the turn signals. I am using red for power--neg, and black for ground--pos. Paul's video shows an in line fuse, but he doesn't state its size. I can splice in a different fuse holder, but what size should I use?

Shouldn't need too high of an amp rating. I would start out low and increase the size if your charger blows the fuse. I have a 5amp fuse in mine (#5 on fuse box) and also run my Garmin GPS.

It is a 3 amp, fast blow, 250 volt fuse. Try it but if it blows, look for a 5 amp and 8 amp fuse of the same size. Then try the 5 amp and if that blows the 8 amp.

Some cell phone chargers consume as much as 10watts during charging. This means the maximum amperage during charging is A = 10W/12v = .83amps for 6volts = 1.7 amps.

Just looked t my phone,it says it was last charged on Friday night,and has 70% remaining right now.But,I don't type on my phone and I don't talk on my computer.Two different appliances to me.

As I have posted a number of times, my cars are drivers. Without wanting to be critical of those chasing points, I see no reason to not convert to 12v. I suspect this car is already on 12 volts. If so, I'd install the socket with a 3 amp fuse and call it DONE. As others have said, if you blow the fuse, simply use a bigger one. A couple of my cars have 2 or 3 of these sockets for a refrigerators, GPS, Phone etc. I use a plug with 2 USB sockets built in so I have a bigger than 3 amp fuse.
Consider how you may be using the socket and use common sense.

Assuming standard positive ground system, attach red (positive) to ground and black (negative) to battery.

3 amps is for 12V supply, may need to use 5 amp fuse for six volts.

I haven't seen Paul's video, but I assume also your mount isolates the socket housing from vehicle ground, otherwise it will blow any fuse.

Re: Cell phone charging
 

I believe the mount is adequately isolated. It is all plastic except for the socket itself. Will try a larger fuse. Re: change to 12V, if this were a daily driver, I might do it, but for a hobby car I would rather keep the 6V.

Re: Cell phone charging
 

Here what I did, I bought a lighter charger from the Dollar store and took it apart. Connect the positive to ground and negative to batt power, an inline fuse for safety, mount it to a piece of plastic and mount it somewhere on bottom edge of dash.

Amazon has a bunch of choices. I got one that has a cigar lighter socket and 2 USB jacks. Install a fuse and an on/off switch because mine draws current all the time even when nothing is plugged in!
