With the mom charger on realme gt 2 and measuring with Ampere, it went from 40 to 90% in 15 minutes and from 34 to 82% again in 15 minutes.
The Ampere app showed 5600 up to 6,070.
On the gt master edition, it showed 3A but it was at 70% when I tried...
The indication on the gt master edition lock screen still showed that it was charging properly.

The cable is indeed a supervooc 65w and the quality follows that of the mom cable at about 85%.
The cable I'm talking about is the 2-meter version, so you understand that it works perfectly.

Be careful because in the listings they also include another one that is not supervooc (it doesn't say it on the box anyway... even though it says the correct one), but it is probably for Huawei and another one that is 100w which you don't want if you have realme oppo oneplus.

In other words, when searching for supervooc, it will throw in the others easily, but you can change the color, length, etc.

Owners of the above-mentioned phones, look for supervooc clearly written on the packaging, then it will work at 65w as it says for those who are interested.
Until today, for the 2 meters, the CAYS001001, CAYS001002, and the CAYS000901, CAYS000902 for 1 meter.

There is also another one besides Baseus, the tactical 034, which I haven't tried.

Finally, a branded cable in 1 and 2 meters that is Supervooc.
