Magnetic Case for Onyx Boox Note Max 13.3 / Tab X C 13.3 - Slim

In this review of the Magnetic Case for Onyx Boox Note Max 13.3 / Tab X C 13.3 the bottom line is straightforward: it is a slim, dependable alternative to the OEM cover for owners who want lightweight protection with useful extras. The case's single biggest selling point is its magnetic system - a combination of strong magnet adsorption, a magnetic closure and a magnetic pen buckle - which keeps the tablet secure and the stylus in place while also enabling the convenient auto sleep/wake feature that helps preserve battery life.

Key Features

• Magnetic Pen Buckle: a magnetic strap holds the stylus firmly so it is less likely to fall out of a bag or shift during wireless charging.
• Auto Sleep/Wake: the cover automatically wakes or puts the tablet to sleep when opened or closed, reducing unnecessary power use.
• Strong Magnet Adsorption: a powerful magnet keeps the tablet attached to the cover immediately when placed, simplifying installation and removal.
• Magnetic Closure: the cover closes securely to prevent accidental opening and offers 360 degree protection from minor bumps and dust.
• Premium Material: crafted from PU leather with a waterproof PU fabric lining to resist scratches, dust and light spills while remaining ultrathin.

Who It's For

This case is for owners of the 13.3 in Boox Note Max and Boox Tab X C 13.3 Color who want a lightweight, low-profile cover that preserves the tablet's original look while adding functional protection. The magnetic pen buckle and auto sleep/wake are helpful for frequent note takers and readers who carry the tablet in a bag.

Those who should look elsewhere include owners of other Boox generations or different screen sizes, since this case is made specifically for the 13.3 in Note Max / Tab X C and will not fit other models. Buyers seeking heavy-duty drop protection or ruggedized cases should consider thicker, reinforced alternatives.
