Ok, we're not gonna lie, $59 is a hefty amount of scratch for what's effectively a Magsafe plug on the one side, and an EmPower power with a standard 20mm power plug. But it's also one of the most effective ways to power -- not charge -- your MacBook or MacBook Pro (Core Duo
) while in flight that we've yet seen. So at least you don't have to feel unnecessarily guilty about watching The Office in DiVX while on your trans-continental since now you won't dip into that reserve power before landing and putting back on that business cap. Just make sure you're seated in a row with power, though -- we've found other fliers are generally pretty unruly when you try and bogart their juice mid-flight.
