Hello,
I am a brand new user at this forum and I was hoping for some guidance.
I recently fabricated a Micro USB charging cable which taps into my Cigarette Lighter Fuse, and is hidden behind my dash. This was done with a Blackberry Micro USB cable, a 5 volt regulator, and a 3 amp fuse, then grounded to metal body.
But the power output can't give the phone enough power to keep up with the power consumption. The battery is drained about 1% every 3 minutes.
Also to make it a little more confusing, If I were to plug the same model blackberry USB charger into my USB adapter which is then plugged into my cigarette lighter, the phone charges perfectly. The adapter in question has a 1 amp and 2 amp USB outlet. Both work just fine.
At first I thought the cable was to long, since while fabricating it, i was not sure how much length I needed. But just yesterday I tore apart my dash and took atleast 4 feet off the length of the cable, shortening it to around 4 ft. But this did not resolve the problem.
I with much embarrassment, I posted a how to on another car forum before doing any type of long term tests. Show here:

Does anyone know what I have been doing wrong??
The soldering is tight.
