Hi, author here, I've fixed that in the post now.
Great news! By the way, are you Finnish? I've never seen an 'O with tilde' character before.

It's got a CE mark, but it's unclear if it's valid or not. This is a mandatory certification in the EU, like the UL listing in the US. The device is specifying the output voltage, which isn't in spec for the connector, but it is (apparently) accurate.
UL isn't actually mandatory in the US. The only thing mandatory that I am aware of is FCC certification for devices with signals over a certain number of Hz, and they wouldn't care about a USB port being abused.

There's a deceptively similar mark that stands for China Export and does not indicate EU certification[0]. [0] https://www.kimuagroup.com/news/differences-between-ce-and-c...
It is a self-certification mark though so ¯\_(ツ)_/¯
9v or 12v over USB-A is reasonably common here in Asia... You always need to check the voltage rating before randomly plugging stuff in if it isn't from a big manufacturer. For example, the handwarmers I'm using right now are USB-A at 12 volts, but have a dial to adjust the voltage up and down between 0 volts and 12 volts to adjust the temperature (I think it's actually PWM on the 12v power lines, but haven't actuall…
I have the same fountains and I have already roasted an iPad charger on it fountain (I used the charger because it had possibility to connect cable to it instead of plugin directly to the socket). One day it just went out and burnt a little. From that time I tend to use the provided one, but I never noticed it provides a different voltage. Thanks for the warning
An official Apple iPad charger wouldn't fail in this case - it has protection against basically anything on the output side - from short circuits to big back-EMF spikes. 3rd party ones on the other hand....
Really informative article thanks, however, I think that "my two adorable cats" should have a link to the two adorable cats.

Good luck filing an insurance claim for damage caused by the use of a non-UL-listed appliance.
