I just bought a couple of the PowerExtend Cube USB-C. Everything started out great, and my bedside is much simplified.
But: I updated my iPad to iOS 15, and now it won’t charge from the USB-C port on the Cube. I get a message “This accessory may not be supported” when I plug it in.
The iPad still likes my nano II 30w charger just fine.
Just in case, did you try and different cable with the Cube?
I have had that from time to time, and sometimes the charging port needs a cleanin’
Otherwise, look at the cable, as iOS devices are notoriously fussy for ones without a certain component, chip I think, so perhaps the iOS update drove the current cable used to be rendered phhht…
@dickie Try a restart or hard reset of your iPad. Used to get this a few times on iPhone after an update, hard reset normally resolved the warning prompt.
Thanks @ndalby, that did the trick. Just a normal power off and back on.
