    I have an iPad Mini 2 and an iPhone 7 both on the public beta. I use the Apple iPad 12W charger and Apple lightning cable (the one that came with with iPhone) for both, but on the iPad it comes up with "This accessory may not be supported". The same charger / cable combination has no problem with any of the other iOS devices (still on 10.3) in the house.

    I've tried various restart methods to cure the issue for 10.3 devices but to no avail.

    Its a bug in beta 2. Just started for me and many others in the larger bug thread. @gwhizkids found a workaround. Plug the cable into your device, then the cable into the wall or computer, it will work. But if its already plugged in the wall then you plug it into your device, you get the error.

    Interesting, thought I had tried that. It only affects certain devices? Because my iPhone has no problem with the cable already plugged in.

    I've only seen it affecting iPads. Mainly Air 2s from what I have seen around here.

    Its really weird how that happens. Same code, but iPads are affected in a way that iPhones are not.

    BTW thanks for giving me my 5000th like. :D

    iPhone 6s+ not affected on the same chargers and lightning cables.

    iPad Air 2 just started doing this. I can't charge it on the new 2017 iMac, or a wall charger, all my accessories are official apple.com purchased stuff.

    I just googled and saw loads of sites reporting this now on iPad Air 2, and public beta 2. Some say dev beta 2 as well. I indeed run ios11 public beta 2

    Try the workaround I mentioned above.

    My ipadpro9.7 does not have this problem, but my iPad air1 did after the updates to 11b2i and 11b2j. Fortunately, I tried plugging the iPad into a wall socket, and it worked, and has worked correctly each time since. Very strange.

    I did, i charged it to 40%, watched en episode of Seinfeld and fall asleep, woke up just now to a dead iPad.

    Anyway, the lightning cable, i put it in the iPad while the thing was in the socket charger. 12w from Apple.
    I got the msg, I dismiss it, I unplug the charger from the wall and plug it back in and it charges the iPad.

    Glad we have a workaround :)

    I have turned the cable around and it seems to take on my iPad

    I've occasionally have that problem and found turning cable end around seems to make it work. I've also found dust in the port causes this occasionally

    iPad Air 1 is also affected. Luckily, the mentioned workaround works :)

    Scared the hell outa me, my iPad was actually draining while plugged in and I was dreading it running out of juice and never being able to charge it again. What works for me is pulling the usb out of the plug and pushing it back in.

    This seems to be resolved with the beta 2 update 1 thing.

    Other option is to turn off the ipad while it's charging. The software bug that is causing the issue doesn't affect it when the device is off. At least that's a fix for overnight charging, as I've myself plugged in my Air 2 at night with 20% left, and woken up to find it's at 3% left, cause I didn't notice the charge plug didn't take (I wasn't getting the incompatible device error message, just would ding, and then the charge icon would disappear). Turning it off at night seemed to do the trick for now. Will try it with the latest Beta 2 Update 1 release, which I just installed on my iPad.

    I stumbled on the fix - plug in to iPad before the socket and it seemed to be charging again. I was worried I was about to end up with a dead Air 2.

    Good to hear it’s a common bug and hopefully fixed in the next beta.

    IPad mini 4 has this problem. Figured out the workaround by plugging in first to iPad.

    I have the same accessory error on an iPhone 5s - so not only iPads.
    Thought it was the old generic charger that I have used on different devices for years, but the original Apple stuff does the same.
    Always works if I plug in the iPhone first, then the other end of whatever I am using for charging.
    Annoying (just a little), and I hope it gets fixed in a coming beta.

    Me too, and I'm pretty sure B2update1 doesn't fix the 5S

    That worked for me for a few days, but no longer works for me.

    It's affecting my Air 2 and my iPhone 6.

    I tried charging while it was turned off, but that didn't work for me.

    I tried using both OEM and MFI charging cables.

    You powered the device completely down, and left it off while leaving it plugged in, and it still didn't work? Hmmmm. Not sure what to tell you at this point. For me, that was the absolute worst case scenario, and doing the "unplug the cable from the charging adapter, and plugging it back in, while leaving the lightning end in" trick has been working for me.
