I bought an Apple Pencil Pro for my iPad Air M2 last month and spent the better part of an hour trying to figure out why it would not pair. The setup steps on Apple’s site assume you already know which Pencil model you have and which iPad you have, and the pairing method is genuinely different for each combination. This is the version of the guide I would have wanted: which Pencil goes with which iPad, exactly what to do for each pairing method, and the three setup mistakes I made so you do not have to.
The reason this is more annoying than it should be is that Apple has shipped four distinct Pencil models in the last decade, and the pairing method is genuinely different for each. The Pencil Pro and the 2nd generation pair and charge magnetically on the side of the iPad. The USB-C model pairs via a USB-C cable and charges via the same cable. The 1st generation plugs into the iPad’s Lightning port to pair, or uses an adapter for newer iPads. If you try the wrong method, pairing will simply fail silently, with no error message and no clue about what went wrong.
Which Apple Pencil works with your iPad
Before you do anything else, confirm you have a Pencil model that is compatible with your iPad. The four models are visually similar and the boxes are similar, but the pairing method is different for each. A quick reference:
- Apple Pencil Pro. Works with iPad Pro (M4), iPad Air (M2 and later), and iPad mini (A17 Pro). The Pencil Pro is the current top-tier model, with squeeze and barrel-roll gestures in addition to the standard tip functionality. Connects magnetically to the side of the iPad.
- Apple Pencil (USB-C). Works with iPad (10th generation), iPad mini (6th generation), iPad Air (4th generation and later), and iPad Pro (all USB-C models). This is the budget model. Pairs via a sliding-cap USB-C connector and does not charge magnetically.
- Apple Pencil (2nd generation). Works with iPad Pro 11-inch (1st through 4th generation), iPad Pro 12.9-inch (3rd through 6th generation), iPad Air (4th and 5th generation), and iPad mini (6th generation). This is the prior top-tier model. Connects magnetically to the side of the iPad.
- Apple Pencil (1st generation). Works with most older iPads that have a Lightning port, plus iPad (10th generation) via a USB-C to Apple Pencil Adapter. Plugs into the Lightning port to pair.
How to tell the models apart by looking at them: the Pencil Pro and the 2nd generation both have a flat side designed for magnetic attachment to the iPad. The USB-C model has a sliding cap that reveals a USB-C port underneath. The 1st generation has a removable magnetic cap on one end that covers a Lightning connector. If your Pencil has a flat side and is silver or white, it is either a Pro or a 2nd generation, and the only way to tell the difference is by the iPad you are trying to pair it with.
The compatibility gotcha that bit me: I had a 2nd generation Pencil and a 2024 iPad Air M2, and the iPad Air M2 only supports the Pencil Pro. The 2nd generation Pencil will not pair with the M2 iPad Air, and Apple does not make this obvious until you try. The fix was returning the 2nd generation Pencil and buying the Pro. If you are buying a Pencil for a new iPad, confirm the model on Apple’s compatibility page before you order.
How to set up the Apple Pencil Pro (or 2nd generation)
Both the Pencil Pro and the 2nd generation pair and charge the same way. If you have one of these, the setup is the simplest of the four methods.
- Make sure Bluetooth is on. Settings → Bluetooth → toggle on if it is off.
- Remove the cap from the Pencil (if it has one) and any plastic film on the tip.
- Attach the Pencil to the magnetic connector on the long side of the iPad. The magnetic strip is on the right side of the iPad (when looking at the screen in portrait orientation), and the Pencil should snap into place with a satisfying click.
- Wait for the pairing prompt to appear. The iPad should show a pop-up asking if you want to pair the Pencil, with a “Connect” button. Tap Connect.
- The Pencil is now paired. You can start using it immediately for drawing, writing, or navigation.
The charging happens automatically as long as the Pencil is magnetically attached. A full charge takes about 30 minutes from empty, and a 15-second snap-on gives you roughly 30 minutes of use. The Pencil Pro has a small LED on the flat side that briefly indicates charging status, but the 2nd generation does not. You can check battery level in the iPad’s Batteries widget (swipe right on the home screen to get to the Today View, then add the Batteries widget if it is not already there).
How to set up the Apple Pencil (USB-C)
The USB-C model pairs via a wired connection, which makes it the most reliable to set up, and also the one that requires the most cables. The pairing is one-time, and after the Pencil is paired, you can use it wirelessly for drawing, writing, and navigation.
- Make sure Bluetooth is on. Settings → Bluetooth → toggle on if it is off.
- Slide the cap on the back of the Pencil to reveal the USB-C connector. The cap slides firmly and stays in the open position.
- Plug the Pencil’s USB-C connector into the iPad’s USB-C port.
- Wait for the pairing prompt to appear. The iPad should show a pop-up asking if you want to pair the Pencil. Tap Connect.
- Once paired, unplug the Pencil. You can use it wirelessly from this point on.
Charging the USB-C Pencil is also via the USB-C connector. You can charge it from the iPad, from a wall adapter, or from any other USB-C power source. The Pencil charges relatively slowly (it has a small battery), and a full charge takes about an hour. The USB-C model does not have the magnetic charging that the Pro and 2nd generation have, which is the main reason it is the budget model.
The thing I keep forgetting: the cap on the USB-C model is small and not tethered to the Pencil. If you slide it off to charge, set it somewhere you will not lose it. I have lost two already and they are not sold separately in a useful form.
How to set up the Apple Pencil (1st generation)
The 1st generation is the oldest of the four and the most awkward to set up. The pairing method depends on which iPad you have.
For older iPads with a Lightning port, the pairing is via the Lightning port itself. Remove the magnetic cap on the Pencil to expose the Lightning connector, plug the Pencil into the iPad’s Lightning port, wait for the pairing prompt, tap Connect. The Pencil charges from the iPad while plugged in, which is convenient.
For iPad (10th generation) which has a USB-C port, the pairing requires a USB-C to Apple Pencil Adapter. The adapter is a small dongle that came in the box with the 1st generation Pencil when you bought it new, but if you bought the Pencil used, the adapter may not be included and you need to buy one separately. The adapter has a Lightning connector on one end (for the Pencil) and a USB-C connector on the other (for the iPad). Plug the Pencil into the adapter, plug the adapter into the iPad, and pair.
The 1st generation Pencil does not have the squeeze or barrel-roll gestures that the Pro has, and the tip is harder than the Pro tip, which means it wears down faster. If you have a choice between the 1st generation and the USB-C model, get the USB-C. The 1st generation is only worth buying if you have an older iPad that the USB-C model does not support.
The three mistakes I made
These are the things I got wrong on my first attempt, in order of how much time they cost me.
- Skipping the compatibility check. I assumed the 2nd generation Pencil would work with the 2024 iPad Air M2. It did not. The 2nd generation Pencil is not compatible with the M2 iPad Air; only the Pencil Pro is. The compatibility check on Apple’s site is the only reliable source, and it is worth reading before you buy. I lost about 30 minutes of setup time and a return shipment before I got the right model.
- Trying to pair the wrong way. I had a 2nd generation Pencil and tried to pair it by sliding off a cap. The 2nd generation does not have a sliding cap; the cap is for the USB-C model. The 2nd generation pairs magnetically. If your Pencil has a flat side and you are trying to find a cap, you have the wrong model or the wrong pairing method.
- Not checking Bluetooth first. If Bluetooth is off, the pairing prompt will not appear, and the Pencil will not connect. The Pencil itself does not have a power button; it turns on automatically when paired. The whole “is it broken or am I doing something wrong” question resolves faster if you confirm Bluetooth is on before anything else.
The setup is genuinely simple once you have the right model and the right method, and the rest of the iPad experience is the same regardless of which Pencil you have. Drawing apps like Procreate, Notes, and Freeform all work with all four Pencil models, and the tip latency (the delay between moving the Pencil and seeing the line on screen) is similar enough that you will not notice the difference for note-taking or sketching. The Pencil Pro’s squeeze and barrel-roll gestures are the only feature that is genuinely different across the models, and those gestures only work in apps that have been updated to support them.
Trade-offs
Price is the first cost. The Pencil Pro is not cheap. The list price is $129, and the 2nd generation (now sold alongside the Pro at most retailers) is around $99 to $129 depending on stock. The USB-C model is $79, and the 1st generation is $99 but is increasingly hard to find new. The price is the single biggest reason to think carefully about which model to buy.
Use case is the second trade-off. The Pencil Pro’s squeeze and barrel-roll gestures are nice, but they only work in apps that support them, and as of mid-2026 the list of supporting apps is still short. If your main use case is note-taking or PDF markup, the USB-C Pencil at $79 does the same job for $50 less. The Pro is worth the premium if you draw professionally or use a Procreate-class app every day, and it is not worth the premium if you mainly write notes.
Platform lock-in is the third trade-off. Buying a Pencil locks you into the iPad as a note-taking / drawing platform. If you are also considering a Surface or a Samsung tablet with a stylus, the cross-platform question is real, and the Pencil only works with iPads. The Wacom-style EMR (electromagnetic resonance, a stylus technology that does not require a battery in the stylus) styluses that Samsung uses work with Samsung tablets but not iPads, and the Apple Pencil does not work with Samsung tablets. The two worlds do not interoperate.
If you have an iPad that supports the Pencil Pro and you draw or take handwritten notes every day, the Pencil Pro is the right buy. If you have a USB-C-only iPad and the use case is occasional note-taking, the USB-C model is the better value. The 2nd generation is only worth it if you have an older iPad that does not support the Pro. Skip the 1st generation unless you have a specific reason (compatibility with an old iPad, budget constraints that the USB-C model does not meet).
If I could send a message back to the version of me that tried to pair the wrong Pencil with the wrong iPad, I would say two things.
- Check the compatibility page on Apple’s site before you buy. A 30-second read saves a 30-minute return-and-rebuy cycle.
- Confirm Bluetooth is on before you try to pair. The pairing prompt will not appear if Bluetooth is off, and the Pencil does not have a power button or a status light to tell you what is happening.
The Pencil setup is one of those things that is genuinely easy once you have the right pieces, and genuinely frustrating when you do not. The compatibility check is the single thing that separates the two experiences.
