What is the difference between fast charging and flash charging? [Copy link]

Before this, I always thought that the difference between fast charging and flash charging was just an upgraded version. Unexpectedly, an article I saw today mentioned that the principles of fast charging and flash charging are opposite, and the phone will be useless if used incorrectly. The article also mentioned that Xiaomi and Huawei use fast charging, while OPPO and vivo use flash charging.

Seeing this, Guan Guan was shocked. That's not right. I have Xiaomi and OPPO phones at home, but we often use them together. That is the problem of not being able to charge quickly. It's too exaggerated to say that using the wrong phone will ruin it. Or is there any hidden danger?

Friends, what do you think about this? Let's talk about the difference between fast charging and flash charging~

Also, can anyone help me clear up this confusion? Is it true that they cannot be mixed?

'Oh~ marketing gimmick, the poster is very exaggerated. In fact, the chip current is large and the wire is thick, it is normal to mix them. They are all typec interfaces for the purpose of great unification

They are all the same. If the protocols are not compatible, you cannot use the highest power level. You can only use the highest power level that is compatible with the charger and the phone.

Oppo's route is low voltage and high current, the line is specially made, and the general C line cannot activate fast charging

Others are generally high voltage and low current

The common protocol is generally pd 18w

Bao sells a universal protocol conversion module. Bring one with you on a business trip.

It is very convenient to just find a Xiaomi or Oppo store in a shopping mall and start charging directly

Haha, I'm curious when you say that. Universal protocol conversion module, would anyone be interested in DIY one?

That is a DIY product made with a power bank chip and deception.

Oh oh oh oh, that's it

It doesn't matter. The protocol must be passed before charging. Since it can be charged, it means it can be used.

But there is a big difference in charging speed.

Thanks for the answer!
