The Marlon Carry-On is the only smart suitcases that have a removable battery allowed on all airlines. With 20% more packing space, it featured two oversized wheels that allow it to happen. Moreover, the wheel's large diameter shifts the gravity upward. The removable battery is TSA + airline approved, so you can charge your tech anywhere you go. Marlon's padded sleeves protect Laptops, Tablets, and all your tech you carry with you. Furthermore, the Carry-On can be expanded up to 35% more to exploit all the spacious Marlon offers.
