In 2 minutes and 13 seconds, the battery was charged to 50%, and after 4 minutes and 58 seconds, a full charge to 100% was achieved (not only on the display, but also according to the measuring device). The fact is that up to 300 W was not reached, but even slightly over 290 W is literally insane charging power. To put it in context, it is such a value that if you were to charge an electric car with it, you would charge about 2.4 kWh in 8 hours, which would be enough for such a regular car (with a consumption of 17 kWh/100) to drive about 14 km. In 24 hours it would be 42 km, in one year, i.e. 365 days, we would (not including losses) talk about energy to travel more than 15 thousand km. That is, more than what an ordinary European drives in a year.
It is not clear whether a phone will appear in the near future that would support such charging. After all, there are several obstacles here. 300W charging is not in the USB standard, it ends at 240 W. It could then work if a combination of a special charger, a special USB cable and a special phone are simultaneously fulfilled (as a non-standardized solution for the time being, the availability of some alternative chargers and cables with which it would be impossible to assume could be compatible).
