what watt?

[earwigmc]

do any of you happen to know what watt consumption (per whatever time) laptops tend to use

Look at the power supply, rather than the laptop itself. It will have an input and output ranges. While not terribly efficient in themselves, the output power will be the most the laptop will need, but bear in mind this will be for charging the internal battery as well as for running the laptop itself. Depends if you want to run off a 240V inverter, or get a specialised in-vehicle PSU for the PC

Looking at ones I have to hand:

Thinkpad 600 (Pentium 2, 233MHz) - 16V x 3.3A = 53W

Advent (Pentium 3, 1GHz) - 20V x 3A = 60W (PSU says 4.5A- 90W)

Dell (P 4, 1.5GHz) - 19.5V x 6.7A - 130W

Just to give you an idea

ah yes, look at the power supply - thanks =grin=

i was thinking to run it via an inverter, cos i might also power other equipment that way (clippers, etc)... but it'd be worth my while looking at an in-vehcile PSU too, and weighing up my options.

thanks for the examples - the wattage requirements seem pretty low, so i wouldn't need to get a particularly high watt output inverter... i think/hope...?

Min is 15V 6A peak.. so 90W..

thank you =smile=

Just to give you a rough idea, my Macbook Pro runs at 65W. I think you can get travel adaptors that charge slower and run at 45-55W. As oilrig said, it should be stated on the power adaptor.
