Xiaomi Shows Off 300W Fast Charging Tech With Modified Redmi Note 12 Pro+

Charging technology seems to be one of the most rapidly improving areas in consumer tech nowadays, and keeping in theme with MWC 2023, Xiaomi has taken the next leap to be the first to unveil a 300W charging prototype in a Weibo post.

The video shows a Redmi Note 12 Pro phone hooked up to a voltmeter as it starts charging from 2%. In just over two minutes, it was charged up to 50% and the phone indicated a full charge in just under five minutes. During the video, the voltmeter shows the charging wattage go all the way up to a high of 290.6W, although charge speeds of around 280W were sustained for around two minutes before dropping as the phone charged to full capacity. There are a few footnotes to this test, however.
