The power adapter that came with my year-old iPad Pro stopped working

If your Power Adapter was continuously connected to power - and not connected to a device “load” for charging - this will have likely had a detrimental effect upon the Power Adapter.

At its heart, the Power Adapter is a switched-mode power supply. Without delving into detail of how these work, suffice to say that leaving them connected to AC Mains for extended periods, without a load, is not recommended. Aside from other issues, doing so can dramatically shorten the life of the electronics.

Leaving the Power Adapter connected without load also consumes unnecessary power - which, from a “green” perspective is not environmentally friendly. Similarly, as with all AC Mains powered devices, leaving the Power Adapter connected to AC Power when not being actively used presents an avoidable safety/fire risk.

If you wish to extend the lifespan of your power (charging) electronics, you would be well advised to switch-off when unused.

None of Apple's adapters really last long.

I have found over the past 10-11 years that Apple power adapters last any where from 1-2 years and that is pretty much it.

Just purchase another new one from Apple.

They are cheap enough to re-purchase.

OR

Purchase an Apple Mfi ( Made for iPad/iPhone/iPod ) power/charging adapter from a third party, like Anker electronics., as an example.

Much better quality power/charging adapters and they have a great warranty and customer service.

Best of Luck to You!

LotusPilot,

This is really good info that you supplied about this and explains why my Apple power adapters only last less than two years, but unfortunately, I cannot change my charging practices with these.

I use these Apple power/charging adapters ( four 12W and one 20W Apple power adapters ) with a bunch of Apple and non-Apple devices, like a bunch of iPads, two iPhones two Apple Watches, a Pebble watch, small handful of third party rechargeable stylii an Apple Pencil and a set of third party rechargeable earpods, that need charging at different times, so it is just a PITA to keep plugging/unplugging power/charging/adapters all the time, when they are are NOT being used for relatively short periods time.

Easier and cheaper for me just to replace the power/charging adapters staggered out about once every 1-1/2 to 2 years.

You are very welcome. I hope the information proves to be informative and constructive - as opposed to causing undue alarm.

Whilst habitually leaving Power Adapters connected to AC for extended periods (without load) is not good for them, there is no need for immediate concern if left connected to AC on occasion.

You can probably find one at your nearest gas station or Walmart.

😆

That’s true. Good Point, there.
