In three days it completely burned. From what I managed to see, it had a strong light and can fit mobile phones over 6.5 inches. As a power bank, it does nothing.

Very strong light and very powerful horn.
The horn changes sounds if you hold down the button for about 2 seconds. It has several options.
The light has 3 modes. Constant with high intensity, constant with reduced intensity, and strobe.
The hooks that hold the phone are very tight and it is difficult to put in and take out the phone.
I do it very carefully because I have the feeling that they might break.
Otherwise, it is very stable as a base and the phone doesn't come off at all.
It also functions as a power bank. However, in order to pass the charging cable through the bottom hook and insert it correctly into the phone, you have to remove the phone case you are using. Otherwise, it may cause damage to either the cable or the phone port (with the case, the phone sits slightly higher and the cable goes in diagonally).
The cable of the horn switch is very thin and I don't know how durable it will be. When you connect it to the light, it protrudes quite a bit backward and the cable is strained. It would be helpful, if available, for the mini USB that goes into the light to be angled instead of straight. You have to remove the light when you leave the bike locked outside (otherwise, I think it will "fly away"), resulting in frequently inserting and removing this particular cable from the light.
Finally, you order one color and another one arrives. I ordered black and it came blue.

The battery lasts quite a while. With usage of about 3-4 hours per week on low intensity, it needs to be charged once every 1.5 months (it drops slightly below half). It fully charges in less than 2 hours.
The hooks have not presented any problems even though their feel suggests they might break at some point (they are very tight).
The horn goes unnoticed by people. Its sound is satisfactorily loud, but the available sounds do not attract people's attention. You honk, pass by people, and hear them commenting, "Oh, did it do that?" I'm considering reinstalling the traditional bell.
The plug of the horn switch cable has slightly bent (as expected). At some point, it will definitely break because it protrudes too far backward and you accidentally hit it. As I mentioned above, it should be angled (if such an option exists).
Its weight (for those interested) is 184 grams.

EDIT 12/12/2022
The battery lasts about 2 hours on high intensity. It charges in about the same amount of time.
The high intensity is very good. At intersections at night, it gives the impression to other vehicles that a small motorcycle is approaching.
The horn, as I mentioned above, is loud but indifferent. The mini USB plug is now ready to break.
The elastic cover that covers the USB and mini USB ports has come off somewhere and got lost.
The hooks that hold the phone, as expected, have broken internally, resulting in them opening and closing freely. I improvised with two small metal pieces (maybe I'll upload a photo at some point) and now they are more functional than before.
As a power bank, don't expect miracles. If you're running low on battery, it will keep your phone on for a short while. It either shines for you on the road or charges your phone. You can't have it all!
However, with a relatively long USB to mini USB cable (1m), I can charge the rear light of the bike (while riding) which is also rechargeable and lasts less.
With heavy phones, due to the bike's vibrations, the light tends to tilt downwards and you have to constantly readjust it. It cannot hold the light and a heavy phone steadily at the same time.

In the photo it is black, in the box it shows that it comes in red and blue.. They sent me a red one without giving me the option. On the first installation, a plastic piece came off, not the best quality! However, it has a strong light and the horn is loud with a default sound!
Edit.. Plus one star, it actually has 5 sounds.
