Generic AC adapters for notebooks - safe?

i would not reommend using other than original adapter

matching volts and amps maybe fine for notebook, but sure not the battery charging circuit.

this is an intriicate affair, boost charge, trickle charge, no charge.,

the auto cut-off switch regulates this & i'm not sure the others are duely calibrated, if at all equipped with them !

the smps, if u'll notice is marked 100 - 250 volts input supply ... which indeed is a wide range

even desktop smps units have selector switch for 110 volts / 220 volts ac

only other manufacturer is targus & this i know cause i've seen a number of notebook manufacturers offer optional targus adapters

>> better be safe than sorry

in easy terms you are able to verify the quantity of the wear and tear till you submit a image of the bent adapter on imageshack or photobucket after which the geeks would be drooling over it. uncovered wires or burning smells coming from the capability brick are actual motives for situation - if the top that slots into the computing device seems look after sufficient, i'm guessing you ought to be ok.

They should be fine, just be sure to get the exact same voltage/amps/etc. that the original was.
