What is how to charge apple pencil?

Charging your Apple Pencil depends on which generation you have:

Apple Pencil (1st Generation):

Charging Method: The 1st generation Apple Pencil charges by plugging directly into the Lightning port of your iPad.
How to Charge: Remove the cap on the end of the Pencil to reveal the Lightning connector. Plug this connector into the Lightning port on your iPad.
Charging Time: Charging for just 15 seconds can provide about 30 minutes of use. A full charge takes longer.
Alternative Charging: You can also charge the 1st generation Apple Pencil using a Lightning to Lightning Adapter and a Lightning cable. This is included in the box and allows you to charge from a power adapter or other Lightning-compatible device.

Apple Pencil (2nd Generation):

Charging Method: The 2nd generation Apple Pencil charges wirelessly by magnetically attaching to the side of your iPad.
How to Charge: Simply attach the flat edge of the Apple Pencil to the magnetic connector on the side of your compatible iPad. The iPad will automatically start charging the Pencil.
Charging Indicator: A notification will appear on your iPad screen to indicate that the Apple Pencil is charging and display its battery level.
Ease of Use: This method is much more convenient than the 1st generation's charging method, as the Pencil stays connected and charges automatically while not in use. No need to worry about losing the small cap or a damaged Lightning connector.
