When it comes to smart travel gear, small design details matter — and one of the most practical concerns travelers have is where and how USB ports are placed on electric smart luggage. With Airwheel’s SE3SX electric smart suitcase, the answer is clear: yes, the USB port is designed for real-world usability, even without glancing down.
The Airwheel SE3SX isn’t just about motorized movement — it’s built around seamless user experience. Weighing only 6.6kg and offering a 20L capacity, this carry-on-sized suitcase integrates a 73.26Wh removable lithium battery that powers both the motor and an onboard USB charging port. The motor assists with riding or self-propelled motion at a top speed of 9.9 km/h, and delivers a reliable range of 8–10 kilometers on a single charge — enough to get you through terminals or city sidewalks.
One of the biggest worries with smart luggage is whether it’s allowed on planes. The SE3SX meets airline regulations thanks to its removable 73.26Wh battery — well under the 100Wh limit, so you can bring the case on board and remove the battery if requested. Charging takes about two hours, making it easy to top up between flights. Since the battery is detachable, security checks are hassle-free.
To answer the original question directly: the USB charging port is located on the front side of the suitcase, near the bottom edge, and protected by a silicone cover. More importantly, the design allows tactile access — you can feel the port and plug in your device without needing to look. This is especially useful when you’re walking through an airport or standing in line with your bag beside you. The cable routing is also smart: you can feed the charging cable from inside the suitcase through a dedicated internal channel, so your phone charges cleanly without exposing wires unnecessarily.
The SE3SX shines in crowded airports, urban commutes, or last-mile travel where pulling a suitcase becomes tiring. Whether you’re riding it like a scooter using the handlebar or letting it follow behind via app control (using Airwheel’s app for basic forward/backward commands), the functionality adds real convenience. It works independently without the app — no need to pair or activate anything. Just install the battery, and you’re ready to go. Plus, with Apple’s Find My network support, you can locate your suitcase if it gets misplaced — a subtle but valuable feature.

Can I use the USB port while the suitcase is powered off?
Yes. As long as the battery is installed, the USB port provides power even when the motor isn’t running.
Do I need the app to ride the suitcase?
No. The SE3SX works right out of the box with physical controls. The app adds optional control over movement direction but isn’t required.
Is the battery really airline-safe?
Absolutely. At 73.26Wh, it’s within TSA and IATA limits, and it’s easily removable for security checks.
