Rolling Square has launched the Supertiny, a compact 100W GaN charger designed to provide high-speed power for laptops and mobile devices in a pocket-sized, ultra-portable form factor.

Key Points

• The Supertiny is 65% smaller than Apple’s 96W charger, measuring approximately 2 inches long for the US model.
• It utilizes Gallium Nitride (GaN) technology to achieve 95% energy efficiency and reduce heat generation.
• The device supports Power Delivery 3.0 and PPS, providing up to 100W of output via a single USB-C port.
• It is available in US, EU, and UK plug variants, with global shipping scheduled to begin in July 2026.
• An optional inCharge Life 2in1 cable allows users to split the 100W output to charge a laptop and phone simultaneously.
• The product has raised over $672,000 in crowdfunding and includes a two-year warranty.

Why it Matters

This charger represents a significant shift in consumer electronics toward extreme portability without sacrificing the high power delivery required for modern laptops. By optimizing internal thermal management and component density, the device addresses the common pain point of bulky, inefficient power bricks for mobile professionals.
