We're looking for a power inverter to recharge our Compaq notebook
in the car. Is it better to buy one with a larger rating (400W) rather than
a smaller one? Black & Decker has a 100W model ($13) and it gets
decent reviews:

But the notebook uses ~90W, so we'll be very close to this inverter's
capacity. The alternative is something larger, e.g.

This one's 400W, but we're wondering if the extra cost is worth it.
Thanks for any advice/opinions/info.
The most efficient option is to get a DC-DC converterthat changes 12
volts from the car to the 19 volts the laptop needs.
These are available for under $60US.
