Xiaomi’s new fast-charging tech can fully charge a 4,000mAh smartphone in 17 minutes

The latest Xiaomi Mi 9 can support 27W fast charging via USB-C. While that is fast, it still pales in comparison to Huawei’s 40W SuperCharge and OPPO’s 50W SuperVOOC charger.

The Chinese smartphone brand aspires to do much quicker and their President, Lin Bin, had shared a charging speed test of their upcoming 100W Super Charge Turbo technology. At 100W, this is more powerful that a laptop charger and it is 20X more powerful than the standard 5W power brick that you get with the latest iPhone models.

In the video, the 100W charger from Xiaomi is able to fully charge a 4,000mAh battery smartphone in only 17 minutes. It’s so quick that the device can go from 0-25% charge in just 3 minutes, and it hits the 50% marker in 7 minutes. The OPPO device with a 3,700mAh battery still managed to get an impressive 65% charge in 17 minutes with its 50W charger.

It isn’t clear when Xiaomi will introduce this charging tech commercially and it is likely to debut on a flagship smartphone. They have already announced the Mi 9 and most recently, their gaming sub-brand has also introduced the Black Shark 2. The next flagship expected from Xiaomi would be the successor of the cheap and good Pocophone F1, but we reckon that such fast charging tech would be introduced on a more premium device like the Mi MIX series.
