340 Chargeur Watt GaN pour ordinateurs portables de jeu présenté au Computex

De façon quelque peu inattendue, il y avait une poignée d'exposants de la RPC au Computex et se promenant dans le salon pour la plupart vide, nous avons repéré une société appelée Wii Power (no relation to Nintendo) that had a range of rather interesting Gallium Nitride or GaN chargers on display. The headline product wasn’t even the most interesting model on display, mais à 340 W, it’s by far the most powerful GaN based charger we’ve seen to date. Although it wasn’t a final product based on the looks of the housing, it gives us some insight into what to expect from future laptop chargers. It’s still a rather large power brick at 150 x 86 x 34 mm, but it can deliver 20 V at up to 17 A over the fixed power cable. En plus de ça, it also has a USB-C port with support for USB PD and a range of other charging standards that can deliver up to 45 W.

The company showed off another charger that has a combined output of 240 W and the primary USB-C port supports revision 3.1 of the USB PD standard and can deliver 140 W on its own. The secondary USB-C port can deliver another 100 W, but what makes this product interesting outside of this, is that Wii Power offers an adapter that can combine both of these outputs into a single 240 W output for charging more demanding laptops. There’s even a third USB-C port and a USB-A for peripheral or phone charging, although each port is limited to 30 W and the total output can never exceed 240 W. A built-in display shows the Voltage, Amperage and Wattage that’s being put out. It’s still rather chunky at 130 x 80 x 32 mm, but considering the power it can put out, it’s more compact than most similar non GaN chargers. Finally the company had a compact USB PD 3.1 travel charger that can again deliver up to 140 W, which is the equivalent of 28 V at 5 A. We’re not expecting to see any of these products in their current guise in retail, but it’s a clear sign of what to expect in terms of future charging products.
