According to the latest from China, blogger Wisdom Pikachu would have just given the news that the first Redmi with 300W charging technology will be released around October and that it will be the fastest fast-charging phone in the world.
Redmi 300W fast charging will be released towards the end of the year
In early February, Xiaomi demonstrated the second generation of its 300W charging technology. The engineering prototype is based on the Redmi Note 12 Explorer Edition, which can be fully charged in just 5 minutes.
In particular, the Redmi 300W Second Gen Charging Technology adopts full-link self-developed 300W fast charging architecture. In particular, the 300W Second Gen Charging Technology uses a custom 6:2 charge pump chip. The maximum conversion efficiency of the chip is 98%. After the charge pump is connected in parallel, it directly charges the battery, reaching a super power of 300 watts.
At the same time, the multiple charge pumps adopt a distributed layout, which can effectively avoid heat concentration and extend the charging time at high power. The measured peak power is up to 290 watts, and the power above 280 watts lasts for more than 2 minutes.
In addition, the Xiaomi 300W Fairy Second Charger uses a 15C ultra-high rate battery and innovatively adopts a “sandwich” stacking pattern. The 300W Second Gen Charging Technology is based on a dual string battery design, and the input current of the battery cell is as high as 30A, which requires the battery cell to have an ultra-high charging rate of 15C.
In terms of safety, Redmi's 300W Second Gen Charging Technology provides more than 50 protection and safety elements. Each charge pump has independent overvoltage, overcurrent and overheating protection. In addition, the PCM battery is more efficient and safer than conventional solutions in the industry.
