content: This is one of the most poorly designed and implemented chargers around. I own a 15" Powerbook G4 (which this is listed as being compatible with).The problem is that this isn't actually a 65watt power cord... so don't expect to use your computer while it's charging... and don't expect to be able to touch the "brick" as it's plugged in, you'll burn yourself.I've returned this item and got a charger from another company for just a few dollars more that works a TON better.
