I don't think you need to get a whole converter+empower extension set, I'm pretty sure they sell a standard "addition thing" that just plugs onto the end of the charger you already have (fits onto the three or two pronged plug you usually plug into the wall and enables you to use empower).

I have an Igo power supply for my laptop. Converts auto/plane(empower) voltage to the specs of the laptop. Unfortunately the adaptor plug for the laptop is not exactly the same as the oem. Now the Igo barely works, and I have to jiggle the oem to get it to charge right. I guess it broke the connector in the laptop, and I have to figure out how to get that fixed without spending millions. So make sure you dont move the plug when you have it plugged in.
The same exact thing happened to my iGo!! At first i had to wiggle it to get it to work, but after a while the thing just stopped working. The product is a good idea but the quality of the connectors just blooowwss.
