Redmi launched a special Mercedes-AMG Petronas F1-themed edition of its K50 Gaming phone alongside its vanilla counterpart in China recently. The Xiaomi subsidiary has released the phone with a 120W power brick in the box, rated to run on advanced gallium nitride (GaN) technology provided by the OEM’s industry partner Navitas.

Redmi has introduced its 2022 K50 series of smartphones via its Gaming Edition – and this variant’s special Mercedes-AMG Petronas F1-themed version on top of that. These devices have already brought at least US$45 million in for its brand in its native China already, and just might launch globally soon. 

Ahead of that rumored event, Navitas Semiconductor has just announced that it had partnered with Xiaomi to bring consumers the 120W power brick that comes free with every purchase of the Gaming Edition’s F1-themed variant.

The company’s CEO and co-founder, Gene Sheridan, has noted that it is “excited that Redmi selected [us] for this high-profile…’in-box’ ultra-fast charger“, a move that is apparently the latest phase of the 2 firms’ “long, successful partnership“.

To this end, the K50 variant’s complementary accessory contains Navitas’ “next-gen” GaNFast power integrated circuits (ICs) and GaNSense tech. The company asserts that they allow the K50 Mercedes-AMG Petronas Gaming Phone’s adapter to leverage GaN (rated for up to 20x faster charging speeds compared to silicon) into energy savings of up to 10%.

The GaNSense and GaNFast internals are also touted as more reliable, as they can detect anomalies such as spiked in as little as 30 nanoseconds (ns), or up to “6 times faster” tha other solutions. They contribute to a 0-100% charging time of as little as 17 minutes in the F1 Gaming Edition (also sometimes known as the Redmi K50 Champion Edition).

Then again, even Navitas concedes that this latency can increase to 37 minutes under full load. Nevertheless,  this super-speedy phone – and, hopefully, its power brick – may be very welcome among fans of such cutting-edge charging tech should it truly debut in more markets soon.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
