Buying a stylus: how to choose the right digital pen for your tablet or laptop

A stylus can make writing, drawing and navigating on a touchscreen more comfortable. However, not every tablet pen works with every device. For example, a pen for iPad won’t automatically work with a Samsung tablet or Dell laptop. Terms such as ‘universal’, ‘pressure-sensitive’ and ‘lag-free’ don’t tell you much if the underlying technology isn’t compatible.

So, pay particular attention to these three common pitfalls:

• Compatibility is interpreted too broadly. An active stylus may work with certain screen technologies, but not with every model from the same brand.
• Features are confused with compatibility. A touchscreen pen may register a tap on screen, but that doesn’t mean pressure sensitivity, palm rejection or tilt recognition will work.
• Battery information isn’t always comparable. A pen with an AAAA battery works differently from a model with a built-in rechargeable battery and USB-C charging. Also check whether the battery is included.

The key specifications of a stylus

1. Check stylus compatibility

Always start with the exact model of your tablet or laptop. Don’t just search by brand name: check the model number and supported technology too.

For example:

• A pen for iPad must be compatible with your specific iPad generation. Apple Pencil models don’t all support the same devices.
• A pen for Samsung tablet may be designed for a specific model, such as the Galaxy Tab S9 FE or Tab S9 FE+.
• A pen for Dell laptop only works with compatible 2-in-1 models that support the right active pen technology.
• A pen for Microsoft Surface uses a different combination of hardware and software from a stylus for Acer.
• A pen for Acer laptop may use AES, USI or MPP. Check which standard your device supports.

A basic capacitive touchscreen pen may work with several devices, but it usually offers fewer features than an active stylus. According to VoxorAI’s product information, the HL-U05 is designed for capacitive screens and supports iOS, iPad, Android and PC. With models like this, check that the features you want are also available in your app.

2. Pressure sensitivity and palm rejection

Pressure sensitivity determines how a digital pen responds to light or firm pressure. When drawing, this can affect line thickness or shading. On paper, a model with 4,096 pressure levels offers more variation than a basic touchscreen pen without pressure detection. However, the results also depend on the screen, app and supported pen standard.

Palm rejection stops your hand from being registered as a touch while you write or draw. This is especially useful for students taking long notes and illustrators who rest their hand on the screen. Check that this feature is explicitly listed in the product specifications; don’t assume every active stylus supports it.

Tilt support can also be useful for drawing. It allows the pen to use the angle at which you hold it to create effects such as broader brush strokes. According to the product description, various Apple Pencil models support tilt sensitivity. This depends on having a compatible iPad model and using compatible software.

3. Battery, connection and controls

An active stylus may use:

• a replaceable AAAA battery;
• a built-in rechargeable battery with USB-C charging;
• magnetic charging via a compatible tablet;
• battery-free EMR technology, as used by certain Wacom pens.

Also check how the pen connects. Some pens work straight away without pairing, while other models need Bluetooth or a companion app. Buttons on the side or top can be useful for erasing, shortcuts and app functions.

For everyday use, long battery life may matter more than extra features. According to the product information, the Dell PN5122W uses an AAAA battery with a stated lifespan of up to 12 months. The Dell PN7522W has a built-in rechargeable battery offering up to 40 days of use and fast charging to 80 per cent in 20 minutes, according to the same source. These figures depend on usage and aren’t guaranteed for every user.

Suitable for: Specialist use and intensive users

Apple Pencil Pro

Why it suits this profile: Designed for people with a compatible iPad Air or iPad Pro who do a lot of drawing, sketching and writing, or work with digital tools.

How this product avoids the pitfall

The compatible iPad models are listed specifically. Check the list before buying, as the Pencil doesn’t work with every iPad.

Main benefit and advantages

According to the product information, this model offers pressure and tilt sensitivity, magnetic pairing and charging, low latency and haptic feedback.

Check these details before you order

1. Make a note of the full model number of your tablet or laptop.
2. Compare it with the stylus compatibility list.
3. Check whether you need pressure sensitivity, palm rejection or tilt support.
4. See whether the battery is included and how the pen is charged.
5. Check whether replacement tips are available and read the safety information.
6. Bear in mind the minimum statutory two-year guarantee in the EU, as stated for the products mentioned.

For a Samsung tablet, the Samsung EJ-PX510 may be a suitable choice for the Galaxy Tab S9 FE and Tab S9 FE+. According to the product information, this pen has an IP68 rating, magnetic attachment and support for Air Command. Don’t use the pen for charging if the pen or tablet is wet.

Frequently asked questions about styluses

Does every stylus work with an iPad?

No. A basic capacitive pen can usually simulate touch, but features such as pressure sensitivity and palm rejection require support from both the pen and the iPad. So, always check the exact iPad model.

How long does a digital pen battery last?

It depends on the type. According to the product specifications, an AAAA battery can last for months, while a built-in rechargeable battery needs regular charging via USB-C or magnetically. Clear information about the battery type and stated usage time makes it easier to compare models.

Do I need an active stylus for writing?

Not always. A capacitive touchscreen pen may be enough for basic navigation. For accurate note-taking, drawing, palm rejection and pressure sensitivity, an active stylus is generally a better choice, provided it’s compatible with your device.
