No surprise at all, vehicles have been using mini fuses for decades now…
This will blow your mind, they can also use 6 different size blade fuses maybe more…
I have found that some devices, when plugged into the lighter socket, cause a momentary short circuit while being pushed into place. That blows the fuse in an instant.
It probably has to do with the design of the plug on the device, or the exact rotational angle that the plug is in while being pushed into place.
