It doesn't auto-charge while in use the way the more expensive model does, but with 500 hours of battery life, that's not too much of a sacrifice. It offers the same pressure sensitivity and automatic pairing as the Microsoft Surface Pen, at a much lower price. However, the #1 spot on the list goes to the Heiyo Dia Surface Pen, one of the few budget options that can challenge the performance of the name-brand choices. We moved it up to reflect its excellent performance.

The Surface Pen was previously ranked lower due to the fact that it only works with a specific line of devices, but that's ultimately true of any smart pen until a universal standard emerges. They're precisely configured for the built-in software of their companion machines, meaning they pair seamlessly and draw smoother lines than their competitors. The Microsoft Surface Pen and the Apple Pencil 2nd Generation are purpose-built for the tablets and hybrid devices of their respective companies, and it shows. Unfortunately, there's no such thing as a truly universal active stylus, since the biggest tech manufacturers use incompatible systems, and not all pens will work with all apps.

Unlike passive models, which make use of a touch screen's capacitive sensing without needing to involve software, these pens must connect with a device and a program in order to make use of their advanced features. The biggest limitation for any active stylus is compatibility.
