charger issue/question

[NJ2toU]

When I got my EVO at BB, they of course wanted to sell me a car charger. I said no thanks, as I have a micro USB car charger.

The thing is, it's for my Plantronics Voyager Pro BT. I tried using it, but the charging light comes on for a couple of seconds and goes out. At first I thought it was the charger itself, but then I tried using the BT wall charger and the same thing happened.

I assumed that all chargers were the same, (and we know what assuming does...) within the type of plug they use. Obviously this is not the case. Is it because they use a different amount of power to charge the device or what? Any chance I could seriously mess up my phone by having tried to use it?

So my questions are - why doesn't it work and could I have messed up my phone trying to use it?

thanks!

So sorry guys. After I posted I found. Other threads on this very subject. That's what I get for posting in a rush from work before doing a search. My bad. :-/
