Smart luggage gets a bad rap because the TSA no longer allows batteries in checked luggage. 

A new crowdfunded bag called EBolt has a removable battery, so you can take it with you as carry-on. Then, you can use the battery just like any other pocket charger.

But here's the best part. The company says its KineTech Wheel Technology charges the battery as you roll the luggage!

The 5000 mAh battery is TSA compliant, as is the locking system. 

The bag also has an optional third wheel, so when you push the luggage instead of pulling it, all the weight is resting on the wheels.
