Aircawin Cases Compared Side By Side
Device Compatibility
The most critical difference lies in which e-reader each case protects. Product A, the Aircawin Clear TPU Case for Onyx Boox, fits the Onyx Boox Palma 2, Palma, Kant, and Kant 2. Product B, the Aircawin Clear TPU Case for Viwoods AiPaper, is designed exclusively for the Viwoods AiPaper Reader and AiPaper Reader Colour. Both cases are specific to their respective device models and will not fit prior generations or competing brands. You must verify your exact device model before purchasing either option to ensure a proper fit. This strict compatibility means these cases are not interchangeable between the two device ecosystems.
Screen Size Support
Both cases are engineered for the same physical screen dimensions. The Aircawin Clear TPU Case for Onyx Boox supports 6.13-inch devices. Similarly, the Aircawin Clear TPU Case for Viwoods AiPaper is built for 6.13-inch screens. This matching size ensures that the internal cutouts and bezel protections align correctly with the display areas of both the Onyx Boox and Viwoods devices. The consistent screen size specification suggests that the underlying chassis dimensions of these two different e-readers are likely very similar, allowing for standardized protective shell designs across different brands.
Material Quality
Both products utilize the same high-quality construction materials for durability and clarity. Each case is made from eco-friendly anti-yellow German Bayer TPU. This material choice helps maintain transparency over time, preventing the common issue of yellowing that affects many clear cases. The TPU construction provides a flexible yet protective shell that resists scratches and drops. Both products emphasize this specific material origin to assure you of consistent quality. The use of German Bayer TPU in both cases indicates a shared commitment to premium material standards within the Aircawin product line.
Weight and Portability
Portability is a key factor for mobile e-readers, and weight matters. Product A, the Aircawin Clear TPU Case for Onyx Boox, weighs 1.76 ounces. This specific weight data is provided for the Onyx-compatible model. The specifications for Product B, the Viwoods AiPaper case, do not list a weight value in the available data. Without this specific metric for the Viwoods case, it is difficult to determine if there is a tangible difference in how light each case feels during extended reading sessions. You should assume both are lightweight given the thin TPU construction.
Color Variations
Aesthetic options differ slightly between the two listings. Product A, the Onyx Boox case, offers variations in color options including Transparent, Crystal, and Clear. This gives you three distinct visual choices within the clear category. Product B, the Viwoods AiPaper case, lists only Transparent as the available color option in its current data. If you prefer a specific shade or finish within the clear spectrum, Product A provides more variety. However, if you are strictly looking for a standard transparent look, both products fulfill that basic requirement equally well.
