ABOARD FINNAIR FLIGHT 6 TO HELSINKI - Dinner completed, I was anything but underfed. Finnair, the national airline of Finland, offers a level of service unimagined by denizens of Southwest Airlines or JetBlue.

The computer I was using, a Toshiba Portege 3500 Tablet PC, was looking a little bit hungry -- its battery was running low. So, I plugged it in for a recharge, and took a nap.

By the time I awoke, the Toshiba's lithium-ion battery had been charged fully.

Having "in-seat power," as it's called, is not the newest thing in airborne computing, but it helps. The 4,105-mile flight from New York to Helsinki lasts just over 7 hours.

There's enough time to recharge all the batteries: yours and your computer's.

On Finnair, as on most carriers, the power outlets are in business class, not economy. An upgrade could give the determined road warrior enough "juice" to hit the ground running at his next stop.

Having the power available would be meaningless if I didn't have a new briefcase, the "TravelPower Case" from American Power Company, or APC, of Rhode Island, and the firm's built-in adapter and connectors.

The adapter transforms any sort of power: AC, DC, and any voltage, into the stuff your computer, cell phone and PDA can use.

While the computer charges, I've got a Sony Ericsson T68i cell phone -- a backup -- plugged in for a recharge.

At the same time, I hooked up a Palm Tungsten W PDA/phone for a quick boost.
