Can you use any micro USB charger?

    for the droid. I have other phones that have this charger and rather than buy one for work wanted to know if I could use one of those in the office to charge the phone.

    here's a question:

    I have one of these hardwired into my truck and when I just plug in the micro-USB cable that came with the droid, it will not charge.

    All of my previous pocket pc phones, amazon kindle, everything else that plugs into USB will charge, but the droid for some reason will not.

    This is true also with a single port charger I have in my other cars.

    Anything odd about the droid in this reguard?

    I'm using one i got with my Moto Headset, but when i left it charging for long, it wigged out and went crazy, so i'm not sure if that was just because the charger, which i'm sure it was, or if it was just my phone, which i doubt.

    Short version, from my experience, Not Necessarily.

    There are a number of chargers on the market that provide less than 850MA current. The Droid seems to need at least this much to charge properly. My wife has an LG ENV3, and it seems I can use this charger on my Droid just fine. I bought one off of Ebay (Yeah, I know), that provides 500MA, and it makes my Droid go wiggy, to the point where I am not comfortable using it. I would suspect that any Blackberry charger should work fine.

    YMMV, but I would advise caution.

    Just looked at my BB charger and it's 700MA so it should be fine. I've used it once before, with caution, and it seemed ok. YMMV.

    Do you think the your head phones have the same size and type
    of battery that the droid does? I DON'T THINK SO. :icon_ devil:

    You need not only sufficient current (>500ma), it also needs to be regulated at 5V +/- 0.25V. A lot of the cheap aftermarket adapters are not regulated and they can cause the Droid to go crazy, particularly toward the end of a charge cycle when the phone isn't drawing as much current and the voltage rises about 5.25V.

    Actually it doesn't matter about battery size, it does have the same port, and that's all that matters, i found out the reason it went crazy was because of an app that i installed that didn't agree with it, so when i removed it, it worked fine. The charger works just as it's supposed to. It was a bluetooth moto headset, not headphones, big difference.

    Plus i posted that in late november, so since then it's been working great.

    I have used about 5 different micro usb cables, and none of them have damaged my phone. Micro USB is the standard in the cell phone industry now.

    There are different rated cables though.

    The Droid follows the USB charging spec. In simple form:
    IDCHG is 500 - 1500 mA.
    VCHG is 4.75 - 5.25 V.

    Some USB "chargers" don't short the D+ and D- lines, so the Droid won't draw power from them. Many el-cheapo ones don't meet the voltage/current specs in all conditions.

    The Droid should work fine with a port which only puts out 500 mA, but I believe it will take advantage of more to charge faster, if available.

    I use the micro usb charger I got with my Verizon Mifi interchangably with the charger I received with the Droid. The phone charges nicely on either.

    I know from experience that 435 mA will work.
