This stylus pen is fully compatible with AMZ Fire HD 10, Fire Max 11, and Fire HD 8 tablets (as highlighted in the title), and also works with Samsung Galaxy Tab series, iPhone 16–11 (including Pro, Max, and Plus variants), iPads, and most Android devices—though it doesn't support Windows or Microsoft products. Notably, it's incompatible with devices released before 2018, such as older iPads (1st gen to Air 2, mini 1–4, Pro 1st/2nd gen), early Samsung Galaxy Tabs (1–3, A/E/S pre-2018), and Amazon Kindle devices. Tailored for "Touch Screen" use, it's ideal for daily activities like mobile gaming, web browsing, and quick note-taking (hold at an angle below 90°; not for fine writing or detailed drawing). It has efficient power management: a 30-minute charge provides 6–8 hours of use, with auto-shutoff every 30 minutes to save battery (double-tap to restart), and requires a 5V⎓2A adapter for charging. Plus, it supports magnetic attachment for specific iPads (iPad Pro 3rd gen+, iPad Air 4th gen+, iPad mini 6th gen) and comes with a 120-day extended warranty for a worry-free purchase.
