7-Inch Versus 6.13-Inch Cover Specs
Screen Size Fit
The WALNEW case is designed as a universal fit for devices up to 7 inches, with internal dimensions of 200 x 150 x 20mm. This makes it suitable for 7-inch Kindles, larger Kobo models, and even some iPad Minis. In contrast, the Aircawin case is strictly compatible with the 6.13-inch Onyx Boox Palma, Kant, and Kant 2. If you own a 7-inch device, the Aircawin option will not fit. If you have a 6.13-inch Boox, the WALNEW pouch may be loose or lack the precise protection of a form-fitting shell. You must match the case dimensions to your specific e-reader size to ensure proper protection and usability.
Waterproof Capability
Protection against liquids is a major differentiator between these two covers. The WALNEW case is explicitly labeled as a waterproof dry bag. It uses three zip lock strips to create a secure seal, protecting your device from spills, splashes, rain, sand, and dirt. This makes it ideal for beach trips or poolside reading. The Aircawin case does not offer waterproofing. It is a clear TPU shell designed to prevent scratches, drops, and dust, but it offers no barrier against water immersion. If you read near water or in wet environments, the WALNEW pouch is the only safe choice. The Aircawin case is better for dry, everyday indoor use.
Material and Build
The materials used dictate the feel and durability of each case. WALNEW uses high-quality PVC for its dry bag pouch. This material is flexible and transparent, allowing you to see your device while keeping it sealed inside. Aircawin uses eco-friendly German Bayer TPU for its back shell. This TPU is anti-yellow and features a micro-dot interior pattern to prevent a sticky or wet look. The TPU shell is lightweight and transparent, showing off the original design of the e-reader. PVC is thicker and more rigid in function due to the seals, while TPU is thinner and more flexible. Your preference depends on whether you prioritize a sealed pouch or a slim shell.
Weight and Portability
Portability matters when carrying your e-reader and case together. The WALNEW pouch weighs 2.2 ounces. It includes a lanyard for convenient carrying, which adds to its utility as a travel accessory. The Aircawin TPU shell is lighter, weighing only 1.13 ounces. It does not mention a lanyard, relying instead on the slim profile of the shell to keep bulk low. The WALNEW case is nearly twice as heavy as the Aircawin option. If you want the lightest possible setup for daily commuting, the Aircawin shell is the better choice. The WALNEW pouch adds noticeable weight but offers the benefit of a carrying strap.
Protection Style
Both cases protect your device, but they do so in different ways. The WALNEW pouch provides full environmental protection by sealing the device inside. It protects against liquids, sand, and dust through its zip-lock seals. The Aircawin shell provides physical protection against bumps, drops, and scratches. It features reinforced corners and a bezel that covers the camera and screen to prevent direct contact with rough surfaces. The WALNEW case is better for harsh environments. The Aircawin case is better for preventing cosmetic damage like scratches and fingerprints during normal handling. You should choose based on whether you fear water or physical impact more.
Choose the Right Cover for You

You can still operate the keypad through the transparent surface. It includes a lanyard for easy carrying during water activities.
Onyx Boox Palma or Kant owners
The Aircawin cover is made specifically for 6.13-inch Onyx Boox Palma, Kant, and Kant 2 devices. It uses German Bayer TPU material that is anti-yellow. Reinforced corners protect against drops and scratches. The design allows charging without removal and offers precise cutouts for buttons. It shows the original device beauty.
Travelers seeking universal compatibility
The WALNEW case fits devices within 200mm x 150mm x 20mm. This universal size covers many e-readers like Kindle, Kobo, and Sony models. The clear dry bag pouch protects against dirt and dust. Its lightweight design at 2.2 ounces is easy to carry. You get protection for multiple devices in one cover.
