Heads up: Jaycar has superseded this board with MS4092, which adds USB-C PD and more USB-A ports. If you specifically need the 4-outlet layout with two dedicated USB sockets for phones, this still does the job. Four mains outlets sit behind metal-oxide varistor surge protection and a 10A resettable overload breaker — so a spike from a storm or a dodgy transformer won't take your PC out with it. The two USB sockets share a 3.1A budget (2.4A on one port, 1.55A each if both are in use). Rated for 240VAC 50Hz Australian mains. If MS4092 is on the shelf and you don't need four outlets, grab that instead. But if your setup calls for four sockets and two USB tops-up points, this is a solid, SAA-compliant board that keeps the back of your desk tidy
