OK, now I understand well. THANKS.
In your opinion why does this item cost so little? Yet it looks like the same item. Maybe is it of poor quality?

I don't know why that is so cheap. The price and an Amazon listing isn't enough information.

Have a look at Big Clive's YouTube, where he takes various electronic items apart.

Check the reviews - looking at the same-appearance & ratings ones in the UK, even the ones with a lot of reviews and fairly good, have comments that you can't use them at the claimed ratings.

It could be that the top "100W" can only provide that at 20V; a laptop than needs 15V can only pull 3A, so 45W.

I use a 120W "brick" style (a GAN3). That has a separate figure-of-eight IEC C7 style AC input & I have leads to suit different countries I visit. (I do the same with laptop charger and other AC cables, keeping different types).

Spare AC leads are a lot cheaper than more chargers!

Edit - the charger is like this:

It seems incredible but I could not find its weight on the entire web. A serious company should display the weight of a travel item. I've read everything about the weight: from 230 grams to 390 grams.

Since I will buy a charger like this: 268 W Desktop GaN Charger, I do not want to bring my Laptop charger with me, but I want to use the power supply for all my devices.
So I should buy a suitable cable. Do you think this is good? It costs 15.74 euros.
Is it able to charge the battery of my Zenbook laptop.
Conductor: 24 AWG.
Cable diameter: 4 mm.
Maximum current support: 3A;
Voltage: 12 V.
Maximum wattage: 65 W.

I read this:
sourcing map USB C to DC PD Fast Charging Cable, 3.5mm x 1.35mm, 65W/12V DC, 3A Jack Adapter Converter Adapter for Router, Camera, TV Box, Desk Lamp.

EDIT: The original charger has these specs: Asus Zenbook UX331FN Series 19V 3.42A 65W 4.0 x 1.35mmDoes it still charge if I put a 12V cable in it?

Very unlikely.

For charging, in general 9V or 20V chargers are for four cell batteries, 15 - 16V for three cell, 9 or 12V for 2 cell & 5V for one cell.

Each cell reaches about 4.2V at full charge, and some overhead is required for the charge control circuitry etc.

Try searching for "20V PD to laptop DC cable" and find one that has the correct connector for the laptop?

I can't figure out if this is the right one. The connector must be DC4.0 x 1.35 mm.Unfortunately there are no other cables. Maybe this is the right one:

Anyway 2 hours ago I bought this charger:
https://www.amazon.it/dp/B0DK4Y11RG?ref=ppx_yo2ov_dt_b_fed_asin_title

I fear that I am spending money uselessly. I hope that at least with this new charger I can quickly charge the battery of Osmo Pocket 3 (small camera) and the Amaran Ace 25x LED lamp. I am now charging the Pocket 3 with the USB port of the PC.
But if you think you made a bad purchase, maybe I still have time to send it back.
