Thanks for your replies. Tried reset button but of course it has to be on for that and now it doesn't seem to even start with that basic alert icon in the display (see original attached pic) and my Australian ISP 'Telstra' says "take it to one of our shops for evaluation"... annoying because that's a 2hr return drive... and I'm sure they will just say "it's dead - buy a new one".

Nothing in the manual about spurious display alerts like that... nothing on the web.

But still the question begs - why?? If an Apple charger adapter is just 5v then what happened? Oh well. May never know.

Can only hope the battery has faulted but why would it start initially with the alert on the display... to tell me it's 'broken'?? None of it makes sense. Bummer.

Thanks

As others have said, USB can be either 5V or 9+ volts depending on whether it is regular or QuickCharge. But either way the MR1100 supports both. I routinely use QC2/3 to charge mine using an Anker charger. I also use my Anker charger and/or laptop to charge it at 5V as well.

Though I have never tried to charge my MR1100 with an Apple charger (I have many -- but don't typically use them) I have used apple chargers in the past to run other 5V USB equipment without an issue.

I think the failure of your MR1100 is just an unfortunate coincidence. Or your apple charger has failed/arc'ed/shorted in some way.

Have you tried running the MR1100 without the battery at all? Mine starts right up when the power is applied via USB-C. By all means try to reset it (internal buttom by SIM -- hold it down with paperclip as you apply power). Keep it down for 10-20 seconds. Then remove paperclip while keeping power applied.

This is more likely than many people think. When something goes wrong it is easy to blame the nearest thing.

If it was just a coincidence, then it might be worth investigating the warranty route, if, that is, it still applies.
