If your existing wall plate is the same style as your new outlet with USB and in reasonably good condition, you can put it back in place when your install is complete. Wall plate: Some of the outlets we considered include matching wall plates, potentially saving you a couple of bucks and a trip to the hardware store.Although we prefer the former, we’re okay with USB-C PD outlets that can provide 30 W to one outlet and power another at 15 W at the same time. Many other models, including our top pick, can reach max speeds on only one port at a time if you try to charge two devices, the power is limited, often splitting the max output between the two ports. Combined port speed: Some outlets can power both USB ports simultaneously at their maximum speeds.We expect them to become more common soon, however. Only a few wall outlets available today support USB-C Power Delivery, which can provide up to 100 W of power for laptops and other large devices (though most are rated for less). Such models might save you a few dollars up front, but for years they would be charging your phones and tablets at a fraction of the speed of our picks. So we automatically dismissed any models that charged at less than 12 W without testing. Power level and charging speed: The USB ports on the best outlets can charge devices at the maximum speed allowed by the USB standards, which means up to 12 W (2.4 A) for USB-A and higher for USB-C depending on the voltage.The outlets also need to be laid out so that you can plug in four things at the same time.
To provide four or more USB ports, some manufacturers remove one or both AC outlets, but doing so erases one of the advantages of built-in USB wall charging: freeing up an AC outlet that’s clogged with a USB wall charger. Number and type of outlets and ports: We looked for models with two AC outlets and two USB ports-ideally two USB-C ports-which is the layout that most effectively maximizes space.
