A major technological advance
Realme has made a big splash in the smartphone industry by introducing its 320W SuperSonic Charge system at an event in Shenzhen. This revolutionary system can charge a smartphone from 0 to 26% in a minute and to 50% in less than two minutes, with a full charge in just 4 minutes and 30 seconds. This record surpasses that of Xiaomi Redmi's 300W charger, which took almost 5 minutes for a full charge.
How does this technology work?
Fast charging technology usually works by powering multiple battery cells simultaneously, as opposed to the traditional sequential approach. Realme's demo model stands out for its innovative design: four cells stacked and folded to mimic the shape of satellite panels.
Unique capacity and design
This unique configuration allows for the integration of a 4,420 mAh battery, approximately 10% more capacity than conventional batteries. Each miniaturized cell is designed to maximize charging capacity in a reduced space, increasing the efficiency and speed of charging.
The “Pocket Cannon”: a magazine that lives up to expectations
To support such fast charging, Realme has developed the “Pocket Cannon” charger, which has a power density of 3.3 watts per cubic centimeter. This charger is a significant improvement over last year’s 240W model and is compatible with multiple fast charging protocols, such as UFCS, PD, and SuperVOOC.
Multiple load capacities
The “Pocket Cannon” also offers the ability to charge multiple devices simultaneously, delivering up to 150W for Realme phones and 65W for laptops thanks to its two USB-C ports.
Obsession with recharge speed
Chinese mobile phone manufacturers have become increasingly obsessed with charging speeds, regularly showing prototype systems exceeding 200W in demos. However, actual production models often top out at around 150W, which is still impressive, especially compared to laptop charging speeds.
Concerns and safety
While these extreme charging speeds are appealing, they pose challenges in terms of battery longevity and heat generation. Realme has integrated an “AirGap” voltage transformer to isolate high voltages and ensure contactless electromagnetic conversion, maintaining a charging efficiency of 93%.
