Xiaomi unveiled a major breakthrough with the world’s first 30W fast wireless charging device with reverse-charging capabilities.

It was among four innovations the Chinese tech giant announced on Tuesday, the others being an efficient 4:1 direct-charge architecture, a more secure and stable dual band transmission technology and a universal combination of wired OTG reverse-charging and high-power wireless reverse-charging, all of which will provide higher efficiency for wireless charging.

Xiaomi said its Mi 9 Pro 5G would sport this technology soon.

Compared to its previous 20W wireless charging 2:1 direct-charge architecture, the new 4:1 architecture utilises two levels of charge pump voltage reduction, the company said. This new architecture further improves efficiency while reducing the heat produced during charging, it said. A 30W fan-cooled wireless charging stand can charge a 4000mAh battery from zero to 50 per cent in 25 minutes and to 100 per cent in 69 minutes.

Xiaomi also announced plans to form a wireless charging alliance with leading companies in other industries to promote wireless charging in everyday life settings. — VNS
