ACEFAST V4 Electromagnetic Stylus Pen with Palm Rejection for Tablets

Taking notes on a Kindle Scribe or sketching on a Galaxy Tab shouldn't mean fumbling with charging cables or waiting for a Bluetooth connection. The ACEFAST V4 electromagnetic stylus pen solves that problem at the source — it uses EMR (electromagnetic resonance) technology, so the moment the tip touches the screen, it writes. No battery, no pairing, no downtime.

This acefast stylus pen is built for anyone who reads, writes, or draws digitally every day — students annotating textbooks, professionals marking up documents, or artists sketching on the go. With pressure sensitivity and palm rejection built in, it feels closer to writing with a real pen than most styluses in its class.

For everyday use, that means less time managing your accessory and more time actually using it — pick it up, and it just works.

Key Features

• Instant Electromagnetic Writing — Writes the instant the tip touches the screen, with zero power source, Bluetooth pairing, or charging required — so you're never caught with a dead stylus mid-note.

• Interchangeable Nib Design — Ships with 5 replacement tips and a removal tool, letting you swap out worn nibs in seconds and extend the pen's usable life instead of replacing the whole stylus.

• Magnetic Attachment Storage — A built-in magnet lets the pen snap securely to the edge of compatible tablets, keeping it within reach and reducing the chance of losing it.

• Built-In Eraser Function — A dedicated eraser on the pen body lets you switch between writing and erasing without stopping to change tools or dig through a menu.

• Advanced Pressure & Palm Rejection Controls — Supports palm rejection along with adjustable pressure sensitivity for precise control over stroke thickness, tone, and opacity, so handwriting and sketches look natural.

Why Choose ACEFAST V4 Electromagnetic Stylus Pen

The biggest advantage of this acefast stylus pen is that it removes the maintenance hassle common to most styluses — there's no battery to charge and no Bluetooth connection to lose partway through a lecture or meeting. For students and professionals who rely on digital note-taking daily, that reliability matters more than any extra feature.

Beyond convenience, the combination of pressure sensitivity, palm rejection, and a built-in eraser means it can double as both a writing tool and a light sketching tool, without needing separate accessories. The magnetic storage and replaceable tips also mean it's designed to stay with you and last, rather than becoming a drawer item after a few months.
