If you’ve seen the Airwheel SE3SX electric smart luggage, you might’ve noticed something different—the battery is mounted on the side, not tucked inside the main storage space. It’s a design choice that raises questions: Why put it there? Isn’t it less convenient? Let’s break down the reasoning behind this setup and how it actually improves your travel experience.
The Airwheel SE3SX is a 20L smart suitcase weighing just 6.6kg, designed for urban commuters and short-trip travelers who want more control over their mobility. With a top speed of 9.9km/h and a range of up to 10km, it lets you ride, walk, or pull it like a traditional suitcase. It runs on a 73.26Wh lithium-ion battery—well under airline limits—and supports app-based control for forward and reverse movement. You steer using a retractable handle, and yes, it works perfectly even without the app once the battery is installed.
Placing the battery on the side isn’t arbitrary—it solves real user pain points. First, it keeps the main compartment completely free. Unlike designs that sacrifice internal space for built-in batteries, the SE3SX preserves every inch of its 20L capacity for your clothes, tech, or essentials. Second, accessibility. The side-mounted case allows quick removal—critical when flying. Most airlines require passengers to remove power banks or batteries above certain capacities from checked bags. With this design, you simply unclip the battery and carry it onboard in seconds. No unpacking, no hassle.
The 73.26Wh battery complies with international air travel regulations (under the 100Wh limit), meaning you can bring it on board without special approval. Because it’s removable, you’re in full control of compliance. Just detach it before security if needed, store it in your carry-on, and reattach after landing. Charging takes about two hours, so a quick top-up between flights is totally doable.
This suitcase shines in city-to-city trips, last-mile commutes, or navigating large campuses and transit hubs. Imagine riding from the train station to your office, folding it up, and rolling it into a meeting—no sweat, no heavy lifting. Frequent flyers also appreciate the Find My integration (via Apple’s network), which helps locate a misplaced bag in a crowded terminal.
