CHEAP power supplies

Last Modified: 2015-04-03
I have had a good deal of success on eBay buying power supplies for various things.  Sometimes the results are a perfect fit, and other times, it's an almost perfect fit.

The power supply that I bought for my Asus K55A laptop is just fine in one respect.  If I leave my laptop charging for an hour and come back, then it is fully charged.  However, I have noticed that the mouse gets jumpy if I am using it until I unplug it.  

1.  Is this a case of too much power being supplied or not enough?

2.  Is this a specs problem.  It does say "made in China" (barcode:  43-ICCA, www.sibusa.com) and appears to be made by a company named RoHS.  The part number appears to be ACD83-110114-7100.  
INPUT:  AC100-240V 1.2A 50/60Hz
OUTPUT:  19V ____ (top) --- (bottom) 3.42A (unicode symbol not found)
