Cellphone charging Question

My wife's cell phone wall charger has the same plug as the wall and car chargers for her bluetooth headset. I'm trying to figure out if it is safe to use the bluetooth chargers with her cell phone. Here are the specs as labeled on each charger:

Cellphone Home Charger:
Input: 100-240V AC
Output: 5V DC 0.35A

BlueTooth Home Charger:
Input: 100-240V AC
Output: 5V @ 300mA DC

BlueTooth Car Charger:
Input: 12-24V DC
Output: 300mA DC

I'm most interested in using the car charger with the cell phone, but I don't want to risk messing up the phone. Thoughts?

What about the polarity?

Center Positive, or center Negative?
+ --> -) <-- - or - --> -) <-- +

Not a good idea to charge it backwards.

If the polarity is the same, you should be OK.

Oh! 1000th post.

My guess is that you are talking about a usb port on the phone and bluetooth headset.

USB is standard.

You can even use a usb cable hooked up to the computer at work to charge it.

Bummer. That is the same stadard as the USB plug voltage, though.

If the polarity is the same, I wouldn't see an issue.

The BlueTooth Home Charger is USB on the brick side and ultra-mini round plug on the side that plugs into the accessory. Perhaps tonight I will check polarity.
