A relatively compact GaN charger with 350W power is shown at Computex 2022

Despite nearly empty pavilions at this year's Computex 2022 in Taipei, journalists from TechPowerUp found a curious booth from Chinese company Wii Power (no relation to Nintendo), which showed off several gallium nitride (GaN) cell-based chargers.
Image source: techpowerup.comGaN-cell chargers offer high power at a fairly modest physical size, and the technology promises to dominate the market in the coming years.
The most powerful charger in the range of the Chinese manufacturer was 340W - these have not yet been on the market.
It is presumably a pre-production prototype, besides it is rather bulky - 150 × 86 × 34 mm, though this is excusable if you consider that it outputs up to 17 A at 20 V.
The device is equipped with a USB Type-C port with USB PD support and a set of other connectors that deliver up to 45 watts.Another charger has output power up to 240 watts, but offers more interesting connectivity options.
The first USB Type-C port has 140 watts and the second port has 100 watts.
Then you can connect both cables to the adapter and get all the available 240 watts at the output.
And adapters are available for different laptops.
There is also a third USB Type-C port and a USB Type-A connector for connecting less power-hungry consumers like smartphones.
There is also a built-in display on board, which displays voltage, current and power readings.
The device is also quite bulky (130 × 80 × 32 mm), but not for its capabilities.Finally, it is worth noting and the third exhibition sample - a compact charger rated at 140W (28V, 5A), which will be convenient to take with you on the road.
It is unlikely that any of these chargers will be at retail in the near future, but in the somewhat more distant future with the spread of GaN technology the number of such offers will definitely grow.
