iPad with home button not charging

Verify that the charging cable is properly connected to both the iPad and Power Adapter. If the charging cable won’t properly seat or easily fit into the charging port of the iPad, this might indicate that either dirt or lint is obstructing the plug, or the plug or charging socket have been damaged. A damaged charging cable must be replaced - whereas a damaged charging port must be repaired.

If the problem is due to a visible obstruction, you may be able to remove it yourself*. With good light, using a sharpened wooden matchstick or plastic toothpick, very gently try to dislodge a visible obstruction from the socket. Be careful to avoid damaging the delicate electrical contacts within the socket. Note that a USB-C socket has an obvious "tongue" within the socket.

(*) Removal of an obstruction is often best entrusted to the technicians at the Genius Bar of your local Apple Store or Apple Authorised Service Provider (AASP) - where the appropriate tools and expertise are available:

Troubleshooting generally requires substitution of the Power Adapter and cable for another known-good item. Most models of iPad require a Power Adapter rated at 12W (i.e., 2.4A @5V) or greater to reliably charge. 5W Power Adapters (1.0A @5V) intended for older models of iPhone are inadequate to charge an iPad; if the iPad charges at all, charging will be very slow. Many recent models of iPad are supplied with an Apple 20W USB-C Power Adapter.

Some third-party USB-C power adapters (and portable PowerBanks) may not support USB PD (Power Delivery). Power Delivery mutually negotiates the charging voltage; the source, load and cable are all elements involved in the negotiation protocol. Unless the Power Adapter explicitly supports USB PD, it will almost certainly fail to charge the iPad; proprietary charging standards, such as QC (Quick Charge), are not supported.

If you continue to experience difficulties when using an appropriate Power Adapter of 12W or greater, you might be best advised to seek assistance directly from Apple Support - and request a remote diagnostic test of your iPad. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively you can initiate and manage your support cases from Apple devices using the excellent Apple Support App. If not already installed, the App can be downloaded from the App Store:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to hands-on test and assess your iPad, Power Adapter and cable(s):

I can only suggest the usual - change charger, change cable, check charge port for dust, make sure the case isn't preventing the cable going fully home.

You could try a reset, although I don't know if it will work when the battery is exhausted. Hold the home button and on/off button down until it turns off then on again.

My old iPad...

Just how old is "old?"

— Some iPads are now 16 years old and their batteries are surely dead or close to it.

— Apple have used three different kinds of charge connectors over the years. Wear to the connector can cause issues.

— One newer model seems to be struggling with charging issues since the last iPadOS update.

For reasons like those, we may be able to offer more specific help if you tell us which iPad you have.

Older iPads have a model number on the back in the format "A0000." This is from an iPad 2 WiFi bought in 2012:
