Xiaomi is reportedly planning to mass-produce its 300W super-fast charging technology if the popular tipster Digital Chat Station if to be believed. The technology is capable of fully charging a smartphone in just five minutes and was recently showcased on a modified version of the Redmi Note 12 Pro+. It is expected that this technology will be applied to mass-produced models in the near future.
Xiaomi’s revolutionary 300W rapid charging technology is a result of cutting-edge design and advanced materials, implemented across the charging system, phone architecture, and battery. The integrated GaN (gallium nitride) solution is the key to this technological breakthrough. By utilizing the fourth generation of GaN technology, Xiaomi has maintained the same compact form factor as its 210W charger, while increasing its power output by an astonishing 43 percent, thus achieving a remarkable power density of 2.31W/cm³.
A specialized 6:2 charge pump chip with exceptional maximum conversion efficiency has been integrated into the charging architecture. This addresses the issue of excessive heating from large currents in the charging input path, leading to a decline in temperature rise during charging. Several charge pumps are strategically dispersed in a decentralized pattern to minimize the risk of overheating, enabling sustained peak power output for over 2 minutes.
Using the 300W super-fast charging technology, the Redmi Note 12 Pro+ modified version can completely charge its 4100mAh battery in only five minutes and reach almost 50 percent charge in only two minutes. The charging technology enables a peak power of nearly 290W, which comes very close to the 300W level.
The revolutionary Redmi 300W super-fast charging technology is set to revolutionize the way we charge our smartphones, potentially transforming the mobile landscape. With a remarkable ability to fully charge a smartphone in only five minutes, the technology will alleviate users’ concerns about battery depletion while on the move. This advancement in charging technology also has the potential to extend beyond smartphones and have a significant impact on the charging of other devices, including laptops and electric vehicles.
