It does charge quickly, but whether it charges as fast as it promises, that's another story.
With a 67w Xiaomi charger, the indicator shows up to 27, with a 30w charger the indicator shows up to 15.
This may be due to compatibility issues with Xiaomi, of course, or it could just be a matter of the display.
In any case, it is a quality cable, this particular company has never disappointed me.

I got it because it advertises 6A 66w, exactly what the poco x6 pro or many other xiaomi devices ask for, but unfortunately it only charges with 10w. In terms of quality, it is sturdy and heavy.

Through the Baseus Adaman2 powerbank, the Oppo Find X3 Pro charges with SuperVooc at full speed 30W. If you connect it to an Oppo 65W charger, for example for the X3 Pro, it charges the mobile normally with SuperVooc!
Excellent. Thanks again to chrvks for his informative review!

Edit: After some research, I found that Xiaomi charges with power delivery via type-a port (MiPPS) and it must be the only one that does this. It incorporates a 5th pin in the type-a that acts as a configuration channel. This particular Baseus cable connects to a type-a that is qc3.0 and not MiPPS, so the charging power is lower due to the protocol.
1st review:
- Quality cable from Baseus. Charges phones up to 66W in 11V/6A configuration.
- Its indicator is predictably accurate.
- It is made for high-speed charging on Huawei but also works quite well with Xiaomi. Depending on the model, on some Xiaomi it will reach up to 18W and on others up to 27W.
- Does not charge 20V laptops.
On Oppo/1+/Realme:
It has Oppo's high-current pin and can charge with Supervooc protocol up to 67W.
