Power (Watts) is instantaneous, i.e. it isn't measured per hour. It is in fact a measure of energy transferred per unit time. One Watt is equal to 1 Joule per second. You should be able to run the laptop and charge the battery at the same time. The Power Invertors that are currently available are well protected against overload so that if the laptop does draw too much then the invertor will shutdown. The Laptop will switch to battery so you won't loose anything. The thing to watch out for is the invertor shutting down, the laptop switching to battery, the invertor starting up again because the load has dropped and then the cycle repeating. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting [EMAIL PROTECTED] "I'm a designated driver on the Information Super Highway" -- PowerBooks is sponsored by <http://lowendmac.com/> and...
