# Why Use Polycarbonate Instead of Aluminum for the Outer Shell of the Airwheel Suitcase?## IntroductionWhen choosing a smart electric suitcase, the outer shell material is a key consideration that affects durability, weight, and overall user experience. Many travelers wonder why Airwheel has chosen polycarbonate (PC) instead of aluminum for their smart luggage. This article will explain the reasoning behind this design choice and help you understand whether an Airwheel smart suitcase is right for you.## What is Polycarbonate?Polycarbonate is a lightweight, impact-resistant thermoplastic material widely used in industries like aerospace, automotive, and electronics. Unlike aluminum, which is a metal, polycarbonate offers unique advantages that make it particularly suitable for electric suitcases designed for frequent travel.## Why Airwheel Chooses Polycarbonate### Lightweight for Better PerformanceThe primary reason Airwheel uses polycarbonate is weight reduction. Electric suitcases need to be light enough to be carried onto planes while still containing the motor, battery, and wheels. For example, the SE3SX weighs only 6.6kg, while the SE3T weighs around 9kg. If these suitcases used aluminum shells, they would be significantly heavier, making them harder to carry and potentially exceeding airline weight limits.### Impact Resistance and DurabilityPolycarbonate is known for its excellent impact resistance. It can absorb shocks from drops and bumps during handling at airports, which is crucial for protecting the internal motor and battery components. Aluminum, while strong, can dent or scratch more easily and may not provide the same level of protection for the sensitive electronics inside.### Flexibility and Design FreedomPolycarbonate can be molded into complex shapes, allowing Airwheel to create the sleek, modern look of their smart suitcases while integrating features like the riding platform and handlebar system seamlessly.## Core Features of Airwheel Smart SuitcasesAll Airwheel smart suitcases come with these key functionalities:- **Riding Capability**: Can be used as a personal electric vehicle with speeds up to 13km/h (SE3T, SE3S)- **App Control**: Use the Airwheel app to control forward/backward movement- **Manual Use**: Works without the app – just ride it directly after installing the battery- **Find My Integration**: Apple Find My support for locating lost luggage- **Removable Battery**: 73.26Wh battery that charges in about 2 hours, providing 8-10km range| Model | Weight | Max Speed | Capacity ||——-|——–|———–|———-|| SE3MiniT | 6.8kg | 8km/h | 26L || SE3T | 9kg | 13km/h | 48L || SE3S | 8.1kg | 13km/h | 20L || SE3SX | 6.6kg | 9.9km/h | 20L || SE3SL | 6.8kg | 9.9km/h | 20L |## Air Travel ComplianceAirwheel smart suitcases with removable batteries are generally airline-approved. The 73.26Wh battery falls below the 100Wh limit most airlines allow. Always check with your airline before flying.## FAQ**Q: Can I use my Airwheel suitcase as a regular suitcase without the electric features?**A: Yes, absolutely. All Airwheel suitcases can be used as regular luggage. You can pull them like any other suitcase or ride them when needed. The electric features are optional.**Q: Is polycarbonate strong enough to support an adult rider?**A: Yes, the polycarbonate shell is reinforced and designed to support riders. The SE3T and SE3S models can reach speeds of 13km/h and are built to handle the weight of an adult rider comfortably.**Q: How long does the battery last on a full charge?**A: The battery provides approximately 8-10 kilometers of range on a full charge, which takes about 2 hours. Actual range may vary based on rider weight, terrain, and speed.## ConclusionAirwheel’s choice of polycarbonate over aluminum reflects a thoughtful balance between weight, durability, and functionality. For travelers seeking a smart electric suitcase that’s easy to handle, airline-compliant, and built to last, polycarbonate provides the ideal solution.
