Oppo has finally introduced 125W fast charging technology today. The company calls it “125W Flash Charge”. And it is an evolution of the already fastest 65W SuperVOOC charging solutions and lower VOOCs.
The company through one press release unveiled all the bells and whistles that technology will bring. Developed with SuperVOOC techniques, Oppo reports that 125W technology has undergone a complete hardware upgrade. It can fully charge a standard 4,000 mAh battery in 20 minutes. What the company did not announce was a release date for the technology. This means that we are not sure when we will see a commercial product with technology in action. However, since the company has demonstrated the product, we are quite optimistic.
Double the current, double the power
As before, the 125W Flash charging technology will focus on higher charging currents to maintain power density and effectively reduce charging times while maintaining a fair temperature. The figures include DC 20V at 6.25A.
With this, it doubled the voltage and current capable of SuperVOOC technology. To achieve this protocol, Oppo says it will use batteries made from two 6-C cells instead of the 3-C in SuperVOOC 2.0.
He added that the 6-C layout will give a significant ratio to the battery ratio and will help lithium ion cells last longer despite the high current flow. In addition, Oppo states that the technology will use three parallel charging pumps. It will also be accompanied by a built-in MCU (Microcontroller Unit) to improve charging and conversion efficiency by up to 98%.
No compromises on security
Oppo also said the new technology will feature 10 temperature sensors to monitor charging status, safety and temperature. In addition, it also has overvoltage protection through security, supports Type-C to Type-C cable and has a high-power 128-bit encryption algorithm.
The new Flash Charge technology also has backward compatibility with older SuperVOOC and VOOC protocols with support for 65W PD and 125W PPS, which are Power Delivery and Programmable Power Supply respectively.
Out of nowhere, the release included three other surprises, namely a 65W AirVOOC wireless charging, a 50W mini SuperVOOC and a 110W mini Flash Chargers. While the conceptual wireless charger is slightly larger in size with a dual coil design, the mini versions aim to be the best portable solutions on the go.
Speaking of 65W, it is compatible with the Qi-standard. It can charge a 4,000 mAh battery in 30 minutes, has foreign object detection, five times the security protection and a semiconductor refrigerator at the bottom.
Mini 50W and 110W Flash chargers use GaN (Gallium Nitride) to conduct high voltages and currents in small size. The 50W charger supports 27W PD and 50W PPS protocol. However, the pricing, the availability of these solutions has not yet been revealed.
