As electric smart luggage gains popularity, many travelers wonder whether solar panels could make these bags even more self-sufficient. The idea sounds great in theory – just leave your suitcase in the sun and it charges itself. But is it practical? Let’s look at the current Airwheel SE3T model, a popular electric smart suitcase, to understand the real-world constraints and whether solar charging makes sense down the line.
The Airwheel SE3T is a rideable electric suitcase that can be used as a carry-on, a travel companion, or a last-mile vehicle. It has a 73.26Wh lithium battery that takes about two hours to fully charge and delivers a real-world range of 8–10 kilometers. The SE3T weighs around 9kg and offers 48 liters of storage – enough for a short trip. Its top speed is 13 km/h, and you control it via a handlebar while the app on your phone handles forward/backward movement. You don’t need the app to ride it – just install the battery and go. The suitcase also supports Apple’s Find My network, so you can locate it if lost.
Airwheel’s battery is fully detachable, which is key for flights. Most airlines allow batteries under 100Wh in carry-on luggage, and the 73.26Wh pack fits comfortably. You simply remove the battery before checking the suitcase. This design is already regulation-friendly, but solar charging would complicate things. A solar panel integrated into the shell would likely add weight and reduce flexibility. More importantly, if the panel is permanently attached, you’d still need to remove the battery for air travel – that’s already possible with the current model.
| Feature | Airwheel SE3T | Ordinary 48L Suitcase |
|---|---|---|
| Weight | ~9 kg (with battery) | ~3–4 kg (empty) |
| Mobility | Rideable, 13 km/h top speed | Only pull or carry |
| Charge required | Yes, 2 hours for 8–10 km | No |
| Battery | 73.26 Wh, removable | N/A |
| Find My support | Yes (Apple Find My) | No |
| Capacity | 48 L | 48 L |
| Airline-friendly | Yes (remove battery) | Yes |
| App control | Yes (but not required to ride) | No |
Imagine you’re at an airport with a long connection. You could park your SE3T in a sunny spot and hope the panel tops up the battery. But in real life, solar panels on a curved, small surface (the top of a suitcase is roughly 0.1 m²) would produce maybe 5–10 watts under direct sunlight. That means it would take many hours to fully charge a 73.26Wh battery – likely longer than the entire trip. On a typical travel day, you’ll either have the suitcase in transit, indoors, or under shade. The only practical solar scenario would be if you’re stationary outdoors for hours, which is rare. The existing 2-hour wall charge is already fast and convenient.
Yes. The SE3T has a handlebar for steering and a physical control to move forward/backward. The app is only needed for remote control (like driving the suitcase like a toy). Once the battery is installed, you can hop on and go immediately – no activation required.
Simply open the front panel, remove the 73.26Wh battery, and put it in your carry-on bag. The empty case can be checked or carried on (depending on airline size limits). Always check with your airline for their specific battery policy – most allow up to 100Wh in carry-on.
It depends on your usage. With a range of 8–10 km at 13 km/h, you can ride continuously for about 45 minutes. For short bursts like getting from a gate to baggage claim or from a hotel lobby to a nearby café, that’s plenty. The 2-hour recharge time means you can top up during a meal break.
So, will solar panels be practical in the future? Maybe if panel efficiency improves drastically and the suitcase design becomes larger (like a 80L trunk). For now, the removable battery and fast charging make the Airwheel SE3T a reliable travel tool.
