Wattage Required for Laptop?

Hello,

I was looking at purchasing a DC/AC adapter for my car to charge the laptop I'm purchasing. I plan on getting the Dell Inspiron XPS Gen 2. Can't tell what power it requires from the site.

The Belkin has a 300W power supply that I'm sure would be good, but that might be overkill?

Anyone have comments on how many watts I would need to be sure of not being underpowered for the laptop?

Thanks,
Guy
 
My eMachines M6805 has a 90W tag on the AC adapter, so 300W should be plenty for your Dell.
 
A 100w supply should be fine (depends on what the laptop consumes) but 300w certainly wont hurt especially considering a 300w supply may be of better quality than a 100w.
 
Hi, If your Laptop's input is 12v DC you may be able to buy an adaptor that does not need either the DC to AC or the AC to DC adaptors. Check with the Laptop manufacturer and see if they can supply such a thing. It would be just a twin lead with Cigarette Lighter plug on one end and your laptop plug on the other. Careful. Check it out first. Jim
