Generic Carry On Suitcase Hardside Built In TSA Lock & USB Port Silent Double Spinner Wheels Maximum Underseat Carry-On Bag For American & United Approved Airlines

The integrated TSA-approved lock allows airport security to open the suitcase without damage, using a special key. This is particularly useful for travel to and from the United States, providing added security and convenience.

The suitcase features multi-directional 8 easy glide super silent spinner wheels, which can be interpreted as a double wheel function. This provides enhanced stability and smooth rolling, even when the suitcase is heavily loaded, reducing strain when moving the suitcase.

This suitcase does not have an expandable function. The capacity is fixed, which might limit flexibility when packing extra items or souvenirs during travel. Consider this limitation if you tend to overpack or anticipate needing more space.

This suitcase does not include a brake function. Without a brake, the suitcase might roll away on slopes or in crowded places, requiring you to keep a constant hold of it to prevent unexpected movement and potential accidents.

The suitcase is equipped with a USB charging port, allowing you to conveniently charge smartphones or other devices while waiting at the airport or during travel. This is useful for keeping your devices charged when outlets are not readily available.

This suitcase does not have a front open function. Accessing items requires opening the entire suitcase, which might be inconvenient in tight spaces or when you only need to retrieve a few items quickly. Consider this when packing items you might need to access frequently.
