iPad Pro 11 M2: stopped charging via usb c 2 days ago … unless using original Apple charging block

For six months, all cables or charging blocks worked.. until 6/22/23.


Apparently, after a recent iOS update, the iPad refuses to accept power from anything not plugged into the original charging block.


This iPad is used in many locations around the house where 6-10’ cables are needed, some of them requiring plugging in to a multi USB block or a handheld portable battery source, as AC outlets are unavailable or the original block doesn’t fit or would require an extension cord. Also there is need to charge while traveling in a car. When traveling or outdoors it seems a portable AC power supply (Jackery?) may be needed in order to use the original charging block.


AppleCare was not aware of the problem and after TSing over the phone, the solution provided was that the original official Apple cable needed to be used.


To clarify, the abrupt limitation is not with the cable but the charging block, at least in this case. (dashing to cancel an order for 8 new Apple 10’ cables)


Another observation is that when using a USB-C hub to connect other peripherals, the OS detects the non original power source and pops a message acknowledging the connection, but warning it won’t charge. If the original power block is used to feed into the hub, then the iPad charges normally without the warning.


That warning doesn’t display when connecting directly from the charging block to the iPad. The message only appears when going through a hub. This may be a hint that the issue is not caused by hardware, but a choice made by the operating system.


Thank you for any other ideas to work around this problem.


ps: late 2022 iPad Pro with M2 .. generation # is not noted in system settings or my devices .. maybe a 4 or 6?

These support pages should help with troubleshooting battery and charging issues:

Charge and monitor the iPad battery - Apple Support

If your iPad won't charge – Apple Support


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. Recent models of iPad are supplied with a 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 via a USB-C hub.


Also be aware that USB standards limit USB-C cables to a maximum of 2m. Longer non-certified third-party cables may be available, but may not be usable. Remember, USB-C cables are not all the same. They are “active” - in that they include additional electronics built-in to their connectors.


Also worthy of mention, many computer USB ports also cannot source sufficient power to charge an iPad. Unless explicitly designed for charging connected devices, computer USB ports are typically limited to 0.5-1A @5V (i.e., 2.5-5.0W).


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 from Apple Support. 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 test and assess your iPad, Power Adapter and cable(s):
