Can I replace the Huawei 40W supercharger with a third-party charger but still provide a supercharging feature? I don't know what's those fancy things, but electronic isn't rocket science, but I tried to connect a general 45W charger (non-Huawei), my mate 20 pro only show "quick charging", anyone has an idea why?
No
There are three parts to any charging system other than the old 5V,2A charging :
The charging algorithm, which dictates the power to be drawn at various stages of battery charging. It runs on the device incorporated in OS, including low level changes at kernel level. Note that these are proprietary and hence the sales pitch for different OEMs. (See the charging algorithm
(Source
) of an Anker power bank to get a sense of how complex it can be).
The charger which responds to the requests made by the device and varies voltage or current or both as desired by the algorithm.
USB cable that is capable of carrying the power across from charger to the device. This is the easiest to change, if you know the power requirements.
Unless these three are perfectly aligned, you can't get the desired charging performance. That's why OEMs always insist on using their chargers and cables. Without getting into the specifics of the third party charger you are using (non Huawei), it's obvious that it lacks the capability to meet the demands made by the algorithm. Being a 45 W charger, the device does recognize that it is providing high power and hence displays "quick charging" but cannot super charge.you will get the same results even if you try with any non Huawei charger rated say at 80 or 100W.
