There is no 120 W at all! I bought 2 cables and checked using 2 different Xiaomi 120W DC adaptors from Xiaomi 14T Pro.

below it says 6A, it is not suitable for 120W, only for 30W
for it to be suitable for 120W it must be 10A
the description is not correct, ATTENTION

Very good-quality cable and very fast, without heating up like cheap fast-charging cables.
At €5.50, it’s an excellent buy

I bought this cable specifically for my original Xiaomi 120W charger. Unfortunately, it does not activate Turbo/HyperCharge mode. The phone only shows Fast Charging.
Since the product is explicitly advertised as supporting Xiaomi HyperCharge 120W, it does not perform as described.
I do not recommend this cable if you are buying it specifically for Xiaomi 120W HyperCharge.

It is fast. Perhaps the original charger that came with the Xiaomi phone was a click faster (same orange plug).

The 1m one was actually short in the end. As a cable, it definitely does its job at the 67W I tested it with, and probably even more.

It is the right cable I wanted to replace for my fast charger and to maintain fast charging. Attention! Not all cables are suitable for a fast charger; the wrong cable can "reduce" the charging speed even though a fast charger is being used.

A very good cable. Tested with a Xiaomi 120W charger and with POCO X8 PRO MAX!
Also tested on 5-6 other phones without any problem!

I got it for a Poco 3. With the factory cable it charges at 22W, with the one they sent me it charges at 10W, and it arrived without a box inside an envelope.
It is not for fast charging.

The authentic cable arrived and it really charges at 120W

I don’t know why everyone says it charges slowly; for it to work properly, the device’s charging port must not have any issues, it must support quick charge, and the charger must not be cheap either, 33W+. For me, on REDMI NOTE 14 PRO and 15, it works perfectly, and with power performance checked from a well-known app.

Of course, it wasn't the original cable; it looks one way and arrives another. It gives a slow charging notification

The charging port on my phone had a problem and didn’t fit properly (Xiaomi 13T Pro), and as soon as I took it in for repair, it was like new.

On Redmi Note 9 Pro it worked just fine, like the original cable before it broke! No complaints.

The downside is that the cable does not have any brand name written anywhere, only 'made in China.' Visually, you can't tell if it is authentic or not. During charging, 120-watt charging is supported normally. If it lasts and doesn't break, of course it is worth it as a product.
