Wiring a USB Charger

He guys, I'm gonna add this usb charger to my truck sometime soon.

I'd like to wire it up always hot because it'll be easier for me that way but the part says it has a parasitic draw of 1mA. I know that's not a lot but could this thing kill my battery after a few days of the truck not being started?

I say always on is easier because I have an Aux fuse block installed that is always hot. So I can just run the wires to it without having to splice the oem harness or use an add a circuit. That's plan B, use an add a circuit to an "Ign ON" source.

Wutcha think?

 

It's a pretty simple install... as for the draw... your clock & radio probably draw more current than that with the key off

I put this in, fits below the a/c controls: http://www.banggood.com/1224V-Dual-...-Car-Charger-Adapter-For-TOYOTA-p-958489.html
It was linked on another thread here...I also wanted it Hot all the time, unfortunately it has a blue light in it ended up cutting the switch blank next to it and installing a micro switch, just have to remember to turn it off!

 

Mine has a blue light in it and it sits for weeks and starts right up so I don't understand the whole blue light and turning whatever off

 

My truck can sit for a month or more when I'm working overseas, so yeah, it could be an issue

 

I guess I would not have commented if you would have added that little tid bit.

 

Right on! Thanks for the replies! I don't usually go more than a few days without starting up. I should be good to go always hot.

Last question regarding draw, what if I leave a device to charge overnight? The charger would put out a max of about 5A until the device was charged, maybe a few hours. If the charger ran at 5A for say 3 hours that's 15 amp hours, right? How many amp hours is the starting battery good for?

 

I don't know about all that but I left 2 phones in my car for over 24 hours, and boom started right up

 

Two phones charging I assume.

 

Yup

 

Lol, just making sure! Thanks, it should take more than a cell phone or flashlight charging for a few hours to kill the battery to the point of no start.

 

you be fine. (non-related) I leave my fridge on for like 1-2 days on my main battery and it starts right up.

 

Great, thanks for all the help!

 

Installed! I put it here...



I used a 5A fuse, should be just good enough I hope.

 

I have been wanting to do this. When i installed my aftermarket head unit. I lost my usb charging port. Anyone know how to get it wired back up to work with the aftermarket head unit, soni can use it while driving?

 

I have two installed in the truck.

One in my center console which I use to charge cell phones and GoPro batteries


And the other in the rear cup holder which I run a fridge off of. Plus drinks still fit in the holder.
