There are two ways: since Motorola phones use mini-usb, you can connect it directly to your pc via a mini-usb cable- it should charge that way. The other way is to get a new motorola branded charger- they run about 10-15 dollars at your local big-box retailer. If it still does not charge with known-good cable or known-good charger, then the hardware in the phone has faulted and you will need to go to your carrier and ask for a safety-related replacement (electrical issues = safety issues in my book!)

This model actually uses "Micro" US, not Mini. Forcing a Mini US plug into the slot will damage your unit. You can find the original charger for much less than $15 online. And there are compatible chargers from third parties available for less than that. The charger was the weak link on this unit. We had 2 fail over the life of the phone.

When I try to charge my phone I get unauthorized charge message and the phone won't charge.


Most likely the charger that you bought is not original motorola charger. I would go and buy original motorola brand.

I have a motorola crush and my charger worked fine but now when i plug it in it says unauthorized charger


sometimes any motorola phone will give you this message. The phone will still charge but it has to be powered down to charge. Sometimes turning it off, plugging in, and then powering on will help reset the phone.

Motorola v325 won't charge after using phillips universal charger


Sometimes a bad charger can send a high voltage charge to the phone and fry the charging port on the phone. That is why a lot of the car chargers today have a fuse on them now. So that it will blow the fuse on the charger, instead of frying your phone's charger spot.

Whenever i plug my charher into my motorola razor it says unauhorized charger.


The "unauthorized charger" message is hence telling you that the power
output of your charger is significantly lower than a Motorola charger
would provide. It may or may not still charge the phone, you'll have
to try it to see. If it does charge the phone it will take longer to
do so than a higher power charger would.

Hope this helps. =)

Unauthorized charger everytime i plug it in.


There may be a problem with your charger output. Do you have another charger you could try?

A temporary workaround is to reboot the phone with the charger still attached. It should now say "Authorized" and start charging.

"Unauthorized Charger"


you can try to clean the charger port (but first make sure its not bent, or broken - the pins are really tiny and hard to see, so make sure)
But try cleaning the charge port on the phone and the charger with denatured (rubbing) alcohol, and a toothbrush -

Just make sure not to plug it in when you do this!

and clean both the charger and phone, make sure neither are bent
lastly, try a new charger!

Battery charger


I'm not sure what the problem is with your phone, but this happened to me with another Motorola phone and it turned out to be a battery problem. You can try another charger, which might work for some time before you get the same result, but I believe you will need to replace the battery. You can try calling Motorola and checking to see if they will give you a discount on another battery. I've had several Motorola phones give me this same message and most of the time it was only infrequently and resetting the phone and reinserting the charger worked, but if it persists, try the battery.

Unauthorized charger


I software reset through the settings menu will usually resolve this, or a software update. Make sure you backup your data before doing this though, as you will lose all data in the phone.

If you are unable to do a software update, post a new question regarding this and I would be happy to help you out.
