My father bought it. The power supply did indeed explode, as musictracer says. Since I wasn't present, I wasn't sure if he was exaggerating or not! Finally, because I decided to check the reviews, and seeing this review, I realized that it did indeed happen! He bought a second one (without me knowing) and it simply burned out..
If possible.. Fortunately, they have been checked by the (if) competent Chinese.. here we laugh.

Attention!!! Danger of electric shock!!! I had read the reviews and I knew that at some point the power supply would fail, but I just wanted to retrieve 2 files from my old hard drive and it wasn't worth spending more than 10 euros on an adapter, so I decided to buy it even if the power supply failed at some point. But what happened to me, I didn't expect it. As soon as I plugged it into the socket, the power supply EXPLODED!!! I have never experienced anything like this before. It's not just a joke, it's DANGEROUS!! The bad thing is that it also burned my UPS (mustek 650VA, probably due to the activation of the protection), but luckily the regulator that preceded it (apc 1200i, a different class compared to the mustek) survived. The store was quite helpful and they offered me a refund on their own. Stay away from this product, you are at immediate risk!!!

It works, but...
After 3 days of purchase, and only 2 uses, the power supply burned out.
I would not recommend it.

Tragic.
Simply when you connect it, the entire LAN network and the internet do not work.
To get it back up and running, I have to shut down all the devices connected to the router and the router itself.
In the network, there are Windows XP, 7, and Android mobile devices connected.
I tried it 5 times to confirm, and the adapter was 100% at fault.
Never choose this!
