Huawei working on a new 20W SuperCharge Protocol (SCP)
With the release of the new Huawei Mate 20 Pro, the company announced its ridiculously fast 40W SuperCharge protocol that can charge the 4,200 mAh cell in just 60 minutes from 0 to 100%. But due to the high production cost, the 40W charging protocol was limited to the Mate 20 Pro and the Honor Magic 2. So here's where the rumored 20W SCP comes into play.
A leaked document suggests that the company is working on a new type of 20W charger that uses half the amperage that the SCP Gen. 2 uses. So instead of charging at 10V/4A, the new standard applies 10V/2A and is expected to reach mid-range to high-end devices. It should be announced sometime in 2019 - maybe just in time for the Huawei P30 duo. It's probably even safe to assume that the P30 will settle for the 20W charger while the P30 Pro will go with the 40W.
