Realme once again advances at the forefront of the fast-charging industry after debuting its record-breaking 320W SuperSonic Charge technology that can fully charge a smartphone at the fastest speed ever documented in history.
The new technology, demonstrated on August 14 at the Realme 828 Fanfest event in Shenzen, China, has exceeded its earlier 240 W charger and the 300W tech of rival Redmi.
Fellow Chinese electronic company Redmi held the previous world’s fast-charging technology after powering up a device with a 4,100 mAh battery in just 4 minutes and 55 seconds in February 2023.
Full battery in 4 minutes, 30 seconds
This year, Realme smashed that record after fully charging a smartphone’s battery in 4 minutes and 30 seconds. GSMArena reported that the battery reached 26% after only a minute and 50% in less than 2 minutes during the demonstration.
The feat was achieved using a 4,420 mAh battery with four cells that can be charged simultaneously. Unlike normal charging, the ability to charge multiple battery cells simultaneously allows for faster charging times.
In a promotional video uploaded on X, the scientists developed each battery cell into layered structures less than 3 mm thick to pack more charging capacity into a smaller size before folding the cells into a shape similar to satellite panels.
Realme representatives added that this design provided a 10% higher capacity than traditional ones.
As of this writing, the 320W SuperSonic Charge feature and Redmi’s 300W tech have not been integrated into any company devices. Realme also did not disclose details about the smartphone it used during the demonstration, and updates about the latest technology and the 4,200 mAh four-cell battery have yet to be heard.
Other new releases
In addition to these, the company also unveiled a brand-new power adapter called “Pocket Canon” with an increased power density of 3.3 watts per cubic centimeter.
This marks a significant upgrade from the previous adapter, which has a 2.34 watts per cubic centimeter power density and takes about nine and a half minutes to power up the 4,600 mAh battery of the Realme GT Neo 5 smartphone.
Pocket Canon also features two USB-C ports that let users charge two devices simultaneously. Each port can deliver a maximum of 150W to Realme smartphones and 65W to other compatible devices like laptops.
Further, it can be used with a broad range of fast-charging standards, such as UFCS (up to 320W), PD, and SuperVOOC.
The Realme 828 Fanfest event also witnessed the “AirGap” Voltage Transformer, which uses contact-free electromagnetic conversion to isolate high voltages from smartphone batteries during circuit breakdowns and other electrical faults.
The product works by reducing the voltage to 20V for a risk-free charging experience. It also helps the 320W SuperSonic Charge achieve a power efficiency of 98% while charging to maintain “exceptional conversion efficiency and thermal management.”
Besides batteries and charging, Realme also introduced a solid-state button that offers intuitive tactile controls for instant zoom and quick clicks and an anti-reflective display for smartphones that minimizes reflections by up to 80%.
