You have provided no details of your iPad model.

The 2020 iPad Air (a.k.a. iPad Air4), or 2018/2020 models of iPad Pro, have a USB-C port. All other models of iPad have a Apple Lightning port.

Apple Power Adapters have either an (older style) USB Type-A connector. Recent models of 18/20/30W Power Adapter instead use a USB-C connection.

It follows that you require the appropriate cable for your combination of iPad and Power Adapter. A new iPad should be supplied with both a Power Adapter and correct cable.

From the above information, you will be able to derive the you require the correct cable - which will be one of the following types:

• USB Type-A to Lightning
• USB Type-A to USB-C
• USB-C to Lightning
• USB-C to USB-C
