Apple has launched a new version of its Apple Pencil with a USB-C charging port.

The new Apple Pencil showed up in Apple's online store early on Tuesday. It retails for $79, and is compatible with the 3rd - 6th generation models of the 12.9-inch iPad Pro, all generations of the 11-inch iPad Pro, the 4th and 5th generation of iPad Air, the 6th generation of iPad mini, and the 10th generation iPad.

Do notice that last compatibility note. It's an important one. So far, the iPad only supported the first-generation Apple Pencil.

According to Apple, the new Pencil magnetically attaches to the side of the iPad for storage, but it pairs and charges with a USB-C cable.

Unlike the first generation Pencil, which has a Lightning port aligned with the length of the device, the USB-C port on the new Pencil, hidden under the cap on top, is positioned on the side of the device. This will look odd when you plug it in, though it was likely necessary due to the size of the USB-C port itself.

The price is also notable. At $79, the new Pencil is Apple's most affordable model. The first-generation Pencil costs $99, while the second-generation Pencil retails for $129. The USB-C Pencil lacks a few features, including wireless pairing and charging, pressure sensitivity, and double tap actions. Also, you cannot get it with a free engraving, which is only a feature on the 2nd gen Pencil.

The new USB-C Apple Pencil will be available "early November."
