I recently decided to dedicate my old iPod nano as my "car-tunes" device and since the battery is getting weak I wanted to ensure consistent power for long trips. I bought 2 USB adapters for the cigarette lighter from overstock.com. They are about $3.50 each and decided to convert a blank switchplate on my Honda's dash into a USB power port.
There is nothing revolutionary here, just wanted to add my variation on the theme. I wanted it to look as OEM as possible. I think it turned out real clean.

Step 1: The USB power adapter

It didn't take long to find inexpensive 12v USB power adapters. I found these at overstock.com and they are from eforcity (not a promotion). I was looking for something with a small form-factor and that appeared easy to disassemble. I bought two ($3.50 ea) in case I messed one up, but didn't. I put the second one in the "power port" in my wife's car for the kids to use.
nice, does it get hot?
Thanks,<br>No it does not get any hotter (that I've noticed) than a standard accessory. The amperage is pretty low, so it doesn't charge my tablet very efficiently, but is great for phones and ipods.
I am extremely impressed with your dremel work ! I did something similar in my truck except I used a 2 usb plug and disassembled it like you did. <br>I was very disappointed in the cut I made in my blank so I went to the junk yard and bought a new one because I was so critical of my cuts. <br>Maybe I just need more patience. Any advice ? <br>Excellent work again !
i am having the same problem, and i don't have a dremel kit, <br> <br>is there any instructables on how to do it
I would use a drill to make small holes near (not at) the four corners and then a couple of more in the space to be removed. Once you have done that, you can probably shape the opening with a hobby knife and files. I have used that technique and finished larger holes with a coping saw, too.
very nice and useful!! You've got my vote!
Where did you get the &quot;blank&quot;? This is the single piece I'm trying to find...
The blank was already in the dash for an unused switch. I image you could get one from a dealer, but I would hit the junkyard. It is the same blank plate almost every Honda uses until around 2000. Good luck.
