From the point of view of charging speed, using Huawei 40W super fast charge, the phone can be filled with 70% electricity in 30 minutes (Huawei Laboratory P30 Pro measured, 4200mAh battery).
At present, Huawei 40W super fast charge mobile phones include: P30 Pro, Mate 20 Pro, Mate 20 RS, Nova5 Pro.
40W Super fast charging compatible devices include: 40W Super fast charging electrical appliances, 40W super fast charging mobile power supply, 40W super fast charging car charger, which can fully cover home, office, vehicle environment. ps. There are 22.5W, 18W fast charge series.
In terms of security, Huawei 40W fast charge provides 6 safety protection, which can accurately sense the hand temperature, so as to intelligently adjust the charging voltage and current, and prevent the phone from overheating, and has passed the German TUV Rheinland safety certification.
Huawei Fast Charger has 40w, 50w, 66w, and so on.
To realize the fast charging function on the mobile phone, three elements need to be met: charger, battery and charge IC. The charger needs to meet sufficient output current and output voltage, because the charger line has a large parasitic resistance, if you want to achieve a large charging current, the on-load output voltage of the charger needs to be higher.
At present, Huawei's latest charger is 66 watts fast charge.
