Based on the numbers you provided, it looks like it might have an AC output. If so, the rectification (conversion making the electrons flow only one way to charge the batteries) would be in the phone itself. If this is the case, this would make it totally useless right off the bat.

Even if it is DC, I don't know what type of supply it is. It could have regulated current or regulated voltage. It also may only be suitable for certain voltages (number of cells). It only develops certain currents so it would only be suitable possibly for trickle charging certain cells. It is a real crapshoot. So, unless you have a way of finding some of these things out, I wouldn't recommend you bring it anywhere near a rechargeable battery.

You need something made for charging the type of batteries we use and has the adjustments for current and voltage for different types, sizes and quantities of cells.

Go check this out before you toss them. I have a box full of different wall adapters and chargers which I will put to some use ... eventually ... maybe.

Now THAT'S an interesting article, Claude. Thanks for the link!
MAAC 50249

Planes, Pedals, and Motorcycles! (In that order!)

I stopped being politically correct when I found out that some people were offended by it.
