This is *really* easy to do. Maybe a redesign to prevent?
Thanks for contacting us about this! I’m terribly sorry to hear that this happened.
We had made some changes a few years ago to change the DC barrel and pin size to a less common one, but unfortunately some 12V+ power adapters can still fit.
It’s possible you have an older hub or that you just happened to have a power supply with a compatible plug on it.
Please contact me directly at firstname.lastname@example.org and I’d be happy to assist you further with this issue.
Thank you and my apologies,
