Charges my phone just fine. When the phone is done, the lighter still stays in.

 

I keep one of these little rechargeable flashlights in my cigarette lighter (I don't smoke). Comes in handy!

I use these 90 degree plugs and wire them up to the standard Battery Tender type plug. I also have cigarette adapters that plug into it. Some of the larger 12 volt power pluds will slam into the tank.

It's a Philmore Right Angle Cigarette Lighter Plug Part Number 48-785 LKG Industries, Rockford, IL.
