Several fast charging technology are either available or available now with Quick Charge probably the better known, but Huawei has also showcased their own fast charging solution capable of filling up a typical smartphone battery to about 50% in 5 minutes, and Oppo has been using VOOC in their smartphones since 2014. The second version of VOOC, called Super VOOC, is promising even faster charging as the company showcased a smartphone with 2,500 mAh at Mobile World Congress 2016 that can be charge from about 5% to 100% in 10 to 15 minutes.
Oppo revealed some of the key advantages of the technology in a blog post:
- Charging is always done at 5V, contrary to Qualcomm Quick Charge that starts with the high voltage (12V), and as the battery fills up drops to 9 and eventually 5V.
Temperature is lower compared to competing solution due to the 5V charging, which does not require any extra voltage converter.
Based on 1 & 2, you can charge with Super VOOC while using your phone, contrary to competing solution where the voltage gets back to 5V and slower charging for safety reasons.
The company also explains that Super VOOC is possible thanks to a new low-voltage pulse-charge system and a customized battery without providing further details. The system is said to be completely safe, works through micro USB or USB-C ports, and the Super VOOC flash charge adapter has been redesigned with military-grade materials.
The demo above also show a 50% charge is done in just over 4 minutes. The only downside is that it’s not available in any smartphones right now, but this should change soon.
