Meizu mCharge, Super mCharge

​Meizu's mCharge and Super mCharge solutions are proprietary fast-charging technologies.

The mCharge protocol is based on MTK PE+1.1 protocol.

Super mCharge was introduced in 2017. It can deliver up to 55W of power (up to 11V, up to 5A).

The technology was demonstrated at MWC 2017; Meizu claimed a full charge in about 20 minutes.

Super mCharge uses a charge pump - a switched-capacitor DC-DC converter.

It halves the input voltage, which doubles the output current at the same power. 

Super mCharge monitors voltage, current, and temperature to protect the battery. A dedicated USB-C - USB-C cable with an e-marker chip is used to carry 5A. 

​

Charging protocols:

• mCharge: 5V3A, 8V3A, 12V2A - up to 24W (USB-A - USB-C cable).

• Super mCharge: up to 11V, up to 5A - 55W (5A USB-C - USB-C cable with an e-marker chip).

Meizu 20 Pro and 21 Pro smartphones use 80W charging under the Super mCharge name.
