    Hard Wired Micro USB power for the Droid

    I am looking to install a hard wired micro USB in my car. Does anyone know of a hardwired solution that works with the Droid?

    The only reason I ask is because I have had a couple of chargers that don't work with the Droid.

    I'm NOT looking to hack apart a existing Cig Adapter. I want to get one that has the bare wires for the 12 volts already.

    Thanks,
    Tom

    You are going to need a voltage regulator to drop the voltage from 12-14.4V down to 5V if you want a hard wire solution. It will be cheaper (and easier) to hard wire a hidden cigarette plug in and use a usb adapter. like this:

    Or, if you are a glutton for punishment, you could build your own circuit with this regulator:
    3A Adjustable step down switching voltage regulator

    You would need to mount it to a board, in an enclosure. Supply it with 12V, and set it to 5v out, with a female USB plug wired in on the output side of the regulator. Sounds like a lot more work than it is worth to me.

    Thanks but, I don't want to do a half baked installation. I want something that is going to last a long time and not fall apart in a few years.

    I'm looking for something like this, but for micro-USB (Droid)

    Are you looking for just a cable to connect on the Droid's end or a dock?

    I already have the Motorola Dock. I am just looking for the 12V to Micro USB adapter and cable that can be hardwired into the car. This way I will not have to tie up a (Cig) Power Outlet, since I almost always plug my Droid in while in Navigation Mode.

    Just go to radio shack and get a 12V cigarette lighter adapter. It comes with stripped ends to wire into the car and then just hide it under the dashboard and plug a regular microsub car adapter into that. It will be a neat and clean install without the hassle.

    As I stated in a previous message. I don't want to do a half-baked installation. I want something that is going to be worry-free and last a long time.

    I don't see this as being a reliable or 100% safe idea. Generally those adapters like a little air around them, not buried in a dashboard. Two, I can see the plug coming un-done and posing a electrical risk.

    I know someone has a permanent bare wire adapter for Micro-USB. It's just a question as to whether it will work with the Droid.

    Use your garmin hardwire kit, and pick up a mini to micro usb adapter: USB Mini to Micro adapter from CoolDrives.com

    The Garmin's output is 5V @ 1A, USB 2.0 standard is 5V @ 0.8A output. It will work.

    proclipusa.com

    check out proclipusa.com.. they have vehicle specific mounts for the droid that has a hardwired charger. its a bit pricey, but you are not gonna find a cleaner install. you just slide the phone in and it starts charging. you can get it with or without the magnet that puts the droid in car mode
