So tonight was the first night I tried out a charger I bought from Ebay a couple weeks ago. I compared the output to the original Samsung charger that came with the phone. I noticed that the Samsung charger said it had a 5.0 volt output, while the Ebay charger had a 5.2 volt output. I didn't think much of this other than "Great! It'll charge faster!"
As soon as I plugged my phone (turned on) into the Ebay charger the touchscreen starting acting up big time. It wouldn't respond to button presses and it even had a mind of it's own by going to screens itself, even though I hadn't pressed a button to go there.
I unplugged it and got out my voltage meter. It turns out both chargers were not putting out the specified voltage. The Samsung charger that is rated at 5.0 volt output was actually putting out 5.2 volts. The Ebay charger that was rated at 5.2 volts output was actually putting out 5.62 volts! That's a full 10% over what the phone is supposed to be getting. No wonder the screen wouldn't respond.
Here's the same type of charger I got from Ebay. It has a usb port on the bottom that I plugged a micro usb cable into.

I read a thread here a while back with people complaining about strange behavior from the touchscreen while using aftermarket chargers. My advice is to NOT USE any aftermarket charger that's rated at over 5.0 volts output. This over voltage might not hurt the phone at all, but then again it's better to be safe than sorry.
