On July 15, OPPO introduced fast-charging technology that can reach 125W (20V/6.25A) . As for OPPO's fast charging technology, the SuperVOOC 2.0 that was used in the OPPO Reno Ace 2 and other products announced in September 2019, has achieved 65W. The new technology is nearly double that output.
OPPO says the technology allows the 4,000 mAh battery to be fully charged in 20 minutes, or 41% in five minutes.
The compatible charger has a USB Type-C interface, which is also actually a first for OPPO. Even the 65W SuperVOOC charger had a USB-A port on the charger side.
The reason why USB Type-C was adopted for the charger side is because of its 125W (20V/6.25A) quick charging on a PPS (Programmable Power Supply) basis.
PPS is included in USB PD 3.0, which is a standard for power supply via USB. With a normal USB PD, the output is separated by 5V, 9V, 12V, 20V, etc., but with PPS, the output voltage and current can be changed in real time in steps of 100mV and 50mA.
Incidentally, fast charging with PPS is often referred to by a different name, and Samsung's Super Fast Charging 2.0, which the Galaxy Note 10+ uses, is also PPS.
This 125W fast charger, which has been revealed, also supports 65W USB PD and SuperVOOC, 30W VOOC and 36W Quick Charge.
With such a fast charge, heat generation can be a concern, but of course, that's also addressed. 20V/6.25A input to 10V/12.5A for battery charging inside a smartphone. Three step-down circuits are used in parallel for this conversion. This reduces the voltage/current to be converted in each step-down circuit to 42W at 20V/2.1A and the overloads and heat generation due to high currents are controlled.
In addition to the four existing temperature sensors, 10 new temperature sensors are installed to adjust the temperature of the smartphone to keep it below 40 degrees Celsius.
In addition to the 125W Flash Charge, OPPO has also announced the 65W AirVOOC wireless charging, the slightly smaller 110W mini Flash charger and the 50W mini SuperVOOC Charger.
Unfortunately, as of now, there is no indication of when the smartphone with this technology will be released. However, when OPPO announced SuperVOOC 2.0, they also immediately released a compatible smartphone, so it may be announced soon.
