As scheduled, Lenovo has announced a new 300W Legion GaN charger, alongside several other products, including the Lenovo Yoga Air 14 Ultra and the Lenovo Legion Y70 smartphone, yesterday.
And while laptop chargers are usually the least exciting part of a gaming setup, Lenovo seems to be betting that people are tired of carrying giant power bricks around.
Lenovo Legion 300W GaN Adapter Specifications
The new Legion 300W GaN adapter uses GaN4.0 technology, which allows it to deliver high power output in a smaller body compared to traditional adapters. Lenovo says the charger is compact at a body footprint of 82 x 82 x 33mm, so you don’t have to carry oversized adapters that typically ship with high-performance gaming laptops.
The charger supports Lenovo’s proprietary 20V/15A fast charging protocol and is designed for Legion gaming laptops that run in performance mode.
The adapter uses a three-prong grounded plug design that the company says helps prevent static leakage. It also claims the charger can maintain a stable 300W output by operating within a “golden voltage range” between 200V and 240V.
There are also some smaller hardware touches for durability. It has a reinforced Slim square connector, soft rubber reinforcement around the cable, and a 1.5-meter charging cable in the box. An optional version with a digital display can show real-time charging power through what Lenovo calls its “AI Power” monitoring system.
The adapter supports a long list of Legion laptops from 2023 through 2026, including models in the Legion 7000P, 7000X, 9000P, and 9000X series. Lenovo also says that other laptops using its Slim square charging connector may technically work with the adapter, though charging performance could vary depending on the system and BIOS limitations.
The Legion 300W GaN adapter is priced at 399 yuan (~ $58) in China and will officially go on sale on May 31.
