340 Caricabatterie Watt GaN per laptop da gioco visualizzato al Computex

Somewhat unexpectedly, there were a handful of exhibitors from the PRC at Computex and walking around the mostly empty show, we spotted a company called 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, ma a 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. In aggiunta a ciò, 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.
