Since my OEM charger killed two laptops (I suspect MSW was the instigato), I am paranoid.
I got a 12v charger off ebay. I thought it was cool because it can do a wide range of voltages and plug types. But now....
I can try putting a voltmeter on it and see if it outputs what it says. Are there other things I can look for?
not really anything else to check. could try hooking it up to an automotive head lamp first, see what kind of wattage it puts out (use multimeter in series, set to 10a range). other than that, look for 15-18 volts output
most laptops dont really care that much, the charger just has to get the voltage close and supply sufficient amps (at least 45-60 watts total power, some beastly laptops want 90-120 watts), and the internal power supply circuit of the laptop takes it from there (providing 1.8, 3.3, 5 volts for various internal components)
