How to tell whether the charger of oppo r9 is fast charging or flash charging?

Can't the data cable I bought work? Teach you the difference between OPPO flash charging and ordinary fast charging, and don't buy it wrong again!

In the domestic mobile phone market, OPPO brand is undoubtedly one of the best. At present, many mainstream mobile phones are using type-C as charging interface, focusing on promoting fast charging. The unique OPPO brand is still using the old micro-USB charging interface, and its first super flash charging of up to 60W on the newly released OPPO Reno ace has killed the fast charging of many mobile phones. So what makes OPPO's fast charging technology so powerful?

As we all know, the current fast charging protocol is QC protocol, which is adopted by most type-C interfaces at present. Starting from the 5V2A of QC 1.0 supported by Snapdragon 660, it has reached the highest QC4.0 after several years of development. There are also PD fast charging supported by some mobile phones and most laptops, MediaTek MTK PE protocol, and Huawei FCP fast charging protocol which is also independently developed. In the field of fast charging of mobile phones, it can be said that it is a scuffle between princes.

But different from the above-mentioned fast charging protocol, OPPO creatively developed its own fast charging protocol, namely VOOC flash charging protocol. Why is it different? The first thing to know is that the current mainstream fast charging protocols, whether QC protocol or PD fast charging protocol, all use the method of increasing voltage to force current into the mobile phone battery. Although this is also very fast, it also brings a great burden to the battery, so it often produces serious heat when charging.

However, OPPO's VOOC flash charging is different. It takes a new approach to realize the fast charging technology of mobile phones with low voltage and high current. The advantage of this is also obvious, that is, even if you play while charging, the phone is not so hot. From March 14, when ordinary mobile phones were still using 5V2A charging power supply, VOOC flash charging technology of OPPO 5V4A was born. Suddenly, the slogan "charge for 5 minutes and talk for 2 hours" spread all over the streets. Up to now, the VOOC flash charging on the latest Renault ace has achieved "charging for 5 minutes and battery life for 2 hours".

Multi-contact joint

The self-developed VOOC flash charging technology, because it is different from the mainstream charging protocol, OPPO has re-customized a series of accessories including battery, data cable, charging head and charging interface. Take OPPO's VOOC flash charging microUSB which is widely used as an example. At present, all the products sold on the market are 5-contact needles, and OPPO has customized 7-contact needles. The increase of contact pins also greatly improves the transmission efficiency of current. In this way, some small partners who use OPPO mobile phones often can't use it after buying it back or can't charge it quickly when replacing the data cable or charging head of the mobile phone.

Therefore, some small partners still need to polish their eyes when purchasing the data cable of OPPO mobile phones. It is best to ask in advance, or even formally buy. After all, OPPO's fast charging technology is so strong, but if you simply change the data cable, you can't use fast charging, which is a pity.
