The short answer: First, identify the exact iPad model and Apple Pencil generation. Apple Pencil Pro, Apple Pencil (USB-C), and the 2nd- and 1st-generation models connect differently and are not universally interchangeable. Only with a compatible pair does it make sense to troubleshoot charging, Bluetooth, the case, the adapter, or a possible fault—with an incompatible pair, nothing will happen even if both devices are working perfectly.
Compatibility Is the First Diagnostic Step
The name “Apple Pencil” is not specific enough, and the connector’s shape can be misleading. A typical real-world case looks like this: someone buys a 2nd-generation Pencil second-hand for a 10th-generation iPad, attaches it to the side, and nothing happens. They then assume the Pencil is faulty, even though Apple does not support that combination.
You can find the iPad model under Settings → General → About. You can identify the Pencil generation from the markings on its body and the way it connects. Do not post the serial number publicly in comments or forms; the model designation and generation are enough for an initial inquiry.
Which Apple Pencil Generation Works with Which iPad
The following overview reflects Apple’s current compatibility list (see the sources):
| Apple Pencil generation | iPads listed by Apple | How it connects |
|---|---|---|
| Apple Pencil Pro (requires iPadOS 17.5 or later) | 13-inch and 11-inch iPad Pro (M4 and M5); 13-inch and 11-inch iPad Air (M2, M3, and M4); iPad mini (A17 Pro) | magnetic connector on the side of the iPad |
| Apple Pencil (USB-C) (requires iPadOS 17.1.1 or later) | 13-inch and 11-inch iPad Pro (M4 and M5); 1st–4th-generation 11-inch iPad Pro; 3rd–6th-generation 12.9-inch iPad Pro; 13-inch and 11-inch iPad Air (M2, M3, and M4); 4th- and 5th-generation iPad Air; iPad (A16); 10th-generation iPad; iPad mini (A17 Pro); 6th-generation iPad mini | via USB-C cable |
| Apple Pencil (2nd generation) | 6th-generation iPad mini; 4th- and 5th-generation iPad Air; 3rd–6th-generation 12.9-inch iPad Pro; 1st–4th-generation 11-inch iPad Pro | magnetic connector on the side of the iPad |
| Apple Pencil (1st generation) | 5th-generation iPad mini; 6th–9th-generation iPad; iPad (A16)*; 10th-generation iPad*; 3rd-generation iPad Air; 1st- and 2nd-generation 12.9-inch iPad Pro; 10.5-inch iPad Pro; 9.7-inch iPad Pro | iPad’s Lightning connector |
* Pairing and charging the 1st-generation Apple Pencil with the iPad (A16) or 10th-generation iPad requires the USB-C to Apple Pencil Adapter and a compatible cable.
If your combination is not shown in the table, that does not automatically mean something is faulty—it means you should verify it on Apple’s website, as the list changes when new models are released. Buying a Pencil simply because “it looks the same” is the most expensive way to learn this lesson.
Apple’s Safe Pairing Procedure
- Update the iPad through the standard system update process and charge it.
- Verify compatibility between the specific devices using the table above.
- Connect the Pencil using the method intended for its generation. Place Apple Pencil Pro and the 2nd-generation Apple Pencil in the center of the magnetic connector. For a 1st-generation Pencil with a 6th–9th-generation iPad, remove the cap and plug it into the Lightning connector. With a 10th-generation iPad, use the USB-C to Apple Pencil Adapter and a compatible cable.
- Leave the Pencil connected, restart the iPad, and try pairing it again.
- Go to Settings → Bluetooth and make sure Bluetooth is enabled.
- If the Pencil appears under My Devices, tap the Info button and select Forget This Device. Then reconnect it and wait for the Pair button to appear.
- If the button does not appear, wait one minute to let the Pencil charge, then try again.
- For Apple Pencil Pro and the 2nd-generation Pencil, remove the case or cover—it may prevent proper contact with the magnetic connector—then repeat step 3.
If the Pair button still does not appear, Apple itself recommends seeking service. At this point, it makes sense to stop trying random fixes and have the devices tested.
Do not clean the connectors with metal objects or liquids. When a 1st-generation Pencil is plugged directly into the iPad, do not leave it protruding where someone could knock into it—the connector can break easily in this position, and the resulting repair may cost more than the Pencil itself.
What the Result Means
| Symptom | More likely area of concern | What to bring for testing |
|---|---|---|
| the Pair button never appears | compatibility, discharged battery, interface, or Pencil | iPad, Pencil, adapter, and cable |
| it connects, but the percentage does not rise | Pencil battery or charging path | exact charging time and a screenshot |
| it works without the case | case position or thickness | iPad and the case being used |
| it only stays connected in one position on the side | magnetic interface of the iPad or Pencil | video showing the connection dropping |
| writing cuts out only on part of the display | tip, Pencil, or iPad touch layer | video of the issue and both devices |
| another compatible Pencil works | the original Pencil is more likely to be faulty | both Pencils, if available |
Charging: Where the Connection Most Often Fails
With magnetically charged models, proper contact is crucial. A thick case, a bent plate inside the cover, or debris on the side of the iPad may be enough for the Pencil to stay attached without charging. With the 1st-generation Pencil and the USB-C model, the connector and cable are critical. Common sense applies: test a different cable and power source before considering a repair.
Also check whether the battery level appears at all. A Pencil that pairs and reports a percentage that never increases is a different case from one that does not appear in Bluetooth at all. Make a note of this distinction; it can save ten minutes during check-in.
When Professional Service Makes Sense
If a compatible Pencil still does not respond after completing Apple’s entire procedure, the next step is to determine whether the fault lies with the accessory, the connector, or the iPad’s magnetic and charging system. Ordering a display or port replacement without a comparison test using another known-working device makes little sense—misdiagnosis is especially common with accessories.
Servis PC Brno offers out-of-warranty iPad diagnostics on a pilot basis and is not an Apple Authorized Service Provider. We confirm the price, part option, and repairability only after identifying the model and faulty component, never in advance based solely on the generation. If the device is under warranty or covered by a manufacturer program, contact the seller or Apple first. If the touchscreen is also malfunctioning, see iPad Touchscreen Not Working or Operating on Its Own.
Once you have checked compatibility and completed all eight pairing steps, bring the iPad, Pencil, adapter, and cable for comparison with known-working equipment. This is the quickest way to determine whether the Pencil or something inside the iPad needs replacing. Book an appointment through Apple Service Brno, the booking form, or by calling 774 777 774. In the description, include the iPad and Pencil generations and specify the step at which the procedure failed.
