Accidentally used the wrong power supply

Was very stressed to a gig and my former partner had borrowed my DC power supply for something else. Not being observant I accidentally took the wrong power supply and then I used 1 or 2 other that were also wrong. Luckily they were only plugged in for a couple of seconds each, maximum of 15 seconds but I’d say 5-10 seconds.

My quad stopped to power on with the correct supply after this and was flashing all it’s lights with an interval of 3 seconds. I let it be plugged in and within 5-10 minutes it powered on again without any problems and seems to be working perfectly.

Has anyone made the same mistake or do you think it is damaged internally? I saw a post and someone from staff said there is protection for this kind of error but I am still worried I might have done some damage.

The supply that potentially could damage the QC the most is 12.6V 4A but unfortunately center positive polarity and this seems to be where the biggest risk is. I don’t remember though if I tried with this power supply as well…
