Oppo 125W charger fills a 4,500 mAh battery in 20 minutes but it has some problems

Chinese manufacturer, Oppo, is on top of its game when it comes to fast charging capacity. As of April 2020, Oppo has more than 2,700 global patents in the field of fast charging. The company is already leading in the fast charging field with its 65W SuperVOOC fast charge. Also, it has VOOC, SuperVOOC, and AirVOOC – three major flash charging technology. At ChinaJoy exhibition back in July, we saw the Oppo 125W charger.

According to reports from @DigitalChatStation, Oppo’s 125W charging solution fills a 4500 mAh battery in 20 minutes. However, its upcoming flagship will most likely use its 65W solution. This is because the 125W solution is not quite ready. The heat control is not ideal (it may also be due to the design). 

Oppo claims that this charging solution can deliver up to 41% in just 5 minutes, this is for a 4000 mAh battery. However, it will deliver a full charge within 20 minutes. Also, its temperature remains below 40°C when the screen is off and on standby. OPPO 125W Super Flash Charger supports VOOC, SuperVOOC, compatible with PPS, PD, and QC protocols. It also supports 12.5A current input, multi-pole technology, dual 6C batteries.

OPPO also said that 125W super flash charging technology can be used to charge everything. This means that whether it is a mobile phone, tablet, or computer, it can charge it. Users also do not have to worry about the charging protocol. This technology supports PPS, PD, and QC as mentioned earlier…as long as it conforms to the Type-C interface, it can “flash charge”.

It also comes with five levels of security protection which makes charging fast and safe. The conversion efficiency is as high as 98%, and three charge pumps are connected in parallel. The 125W Flash Charging technology will focus on higher charging currents to maintain the power density. It will also ensure that it maintains the temperature while reducing the charging time. The schematics include a 20V DC at 6.25A.

In a previous press-statement, Oppo did not leave us in the dark regarding what to expect from the 125W flash charging technology. The company believes that this technology is a significant upgrade to its existing SuperVOOC. Unfortunately, Oppo did not announce when we will see a device with this tech. This means that we’re not sure when we will be seeing a commercial product with the tech. Nevertheless, since it is already official, we expect subsequent flagships to do the honors.

Recall that iQOO also showcased its 120W fast charging technology. iQOO claims that its solution can fully fill a 4000 mAh battery in 15 minutes. This seems to be faster than Oppo’s 125W solution. In addition, iQOO 120W ultra-fast flash charger solution comes with TUV Rheinland certification. This is something that we have not seen in the other solutions.
