Self-Propelled Suitcase Drives Itself
If you are too lazy to roll your luggage in an airport, you should look into the self-propelled suitcase by Hammacher Schlemmer. This suitcase provides power assistance when you need it. There are sensors in it that detect how much force is being used to pull it. The motor can propel the suitcase up to three miles per hour when you are struggling with it.
The suitcase is designed to transfer 85% of its carried weight to the wheels. The battery lasts up to 2 hours 15 minutes.
The suitcase can be purchased for $1,300 at Hammacher Schlemmer.
