Dc inverter for sony laptop

[DaveB3D]

I see lots of these with all different specs. from 75watt with continuios 60 wat.t output to others with continuious 300 watt output. Prices from 29.99 to 159.99 What is adequate yet reliable for a laptop? Certainly don't want to fry it or anything....


thanks

I can't find one sony doesn't sell one and I've called everywhere from Bestbuy to radio shack and they all say to get one of these. They plug into the cigarrette light too. then you plug the Ac cord into it...
