Live Luggage calls it a power assisted suitcase; I call it a relief at never-ending airport terminals. This bag uses an antigravity handle that puts 85% of the weight over the wheels.
There are pressure sensors in the handle that monitor how hard the traveler is pulling, then set the wheels to compensate. The battery has about two hours of life but recharges itself when the suitcase is moving. It also has a separate charger with a multi-adapter.
The bag is 33 inches high and weighs about 24 pounds. The price tag? A whopping $1,365.25. Info: liveluggage.com.
