    Had a thought - but need you 12V experts to chime in - I have an extra slot or two in my fuzeblocks box - thought taking an old usb to mini usb cord, cutting off the usb side and wiring it to the box would provide me with a "dedicated" phone charger. I dont know much but I do know that the 4 wires in the cable are red (+5v) black (gnd) and the other two wires are for data.

    My question is this - using the + and Gnd is there other circuitry that needs to be added to condition the power for charging a cell phone?

    You're going to need a DC-DC converter in there somewhere to bump your 12v down to 5, otherwise you will fry the phone. If you're in a hacking mood, you could purchase a standard 12v USB adapter, extract the working bits from the case and solder leads directly to the input/outputs.

    Appreciate the answers....thanks for confirming that there is a conversion to 5v necessary.

    I run 2 of these on my bike. So I can charge phone, camera, mp3 player.

    I've had great luck with 3BR Powersports.

    I have over 20,000 miles on these now with no issues. Rain, vibration, dust. Great addition to the bike. They test and stand behind the kits they put together.

    Might be another plug and play option to take a look at.

    I forgot, they also have a new one that does not look like it's up on there site yet. Call and talk to Kurt or Don with your needs, I'm sure they can get you sorted. :freaky

    I have a standard cigarette lighter socket in my glovebox and can plug in any type of car charger, one of these plug-in USB chargers, my mini compressor, or a cigarette lighter if I have a need for nicotine on the trail. It also works as a place to plug in a trickle charger. Now that I use a tank bag more or less permanently I will soon mount another inside it with a corded disconnect to allow removal.
    Those fancy hard-wired converters shown above look really trick, and i am sure if CJ tested them they are bulletproof but my cheap and nasty side often sneaks up and grabs my nether regions, and the plug-in USB converters are available just about everywhere and are small and cheap enough to carry a spare or two. Some even have 2 or 3 USB ports. Whichever style you choose, be careful of the power rating of the converter and match it to your device/s.
