The UGREEN USB 3.0 Switch Selector is built to keep things straightforward, as it doesn't have a power-off button, which might catch some folks off guard. Our research shows that the absence of a conventional off switch is a pretty common concern.

But don't worry—the switch is designed to always be ready for action, letting you easily share USB devices between two computers with just a press of a button. It's made to stay connected and ready, so having a traditional on/off switch just isn’t part of the plan.

If you’re really keen on turning it off completely, you can do so by either shutting down or disconnecting both of the computers that are linked to it, since the switch draws its power from them.

Another quick fix is simply unplugging it from your USB connections.

The manufacturer also mentions an optional micro USB power source to give extra juice if you're using peripherals that need more power than usual.

Just a heads up—this isn't a power switch for shutting everything down. If power saving is your top priority, just cut off this additional power and your USB connections to switch everything off.

In short, while there isn't a physical off button, the UGREEN USB 3.0 Switch Selector is still efficient for juggling USB devices between your computers.

The UGREEN USB 3.0 Switch Selector can use an external power supply, but it doesn't come with one. The manufacturer notes that if you're using devices like HDDs, USB cameras, or backlit keyboards, a 5V/2A power adapter might be necessary to keep everything operating smoothly.

Based on our research, experiences vary with the need for external power. For simpler devices like a regular keyboard and mouse, it seems to work fine without extra power. However, there have been instances where more power-hungry devices caused some hiccups when not using an adapter. Some folks mentioned issues like disconnections or unstable connections, especially when the power adapter was missing.

Since the switch doesn't come with a power adapter, think about the gadgets you plan to connect. For anything that draws more power, snagging a compatible 5V/2A adapter should help prevent any connection problems. It's a small investment that could save you from future headaches with connectivity.

In short, it really depends on what you're hooking up. If you're unsure or using power-intensive devices, grabbing a power adapter is a smart move to make sure everything runs without a hitch.

The UGREEN USB 3.0 Switch Selector is pretty helpful when you need to share up to four USB 3.0 gadgets, like printers or external drives, between two computers. It's described by the manufacturer as a perfect fit for anyone juggling peripherals across multiple workstations.

When we looked into it, the switch generally works well, but there are a couple of things to keep in mind for smooth sailing. One of the cool features is the 5V/2A power supply port that UGREEN includes. This really comes in handy if you’re hooking up high-power devices such as USB cameras or fancy RGB keyboards.

If you notice disconnections or the switch acting up, it could be because there’s not enough power for all the devices you’ve plugged in. To avoid this, it's often recommended to use an external 5V/2A power supply to keep everything stable.

If you’re using it over a longer distance without extra power, you might run into some trouble with connectivity, especially with bus-powered devices that need more power. Using an external power source and high-quality cables can really help minimize these issues.

One more thing we found: the switch doesn't automatically flip between devices if one turns on or off, which actually prevents those annoying accidental disconnections. But sometimes, if the connection doesn't reset by itself, a quick computer restart might be needed.

If you’re still having problems, it could be worth checking for power grounding issues or considering a different unit, as the problem might just be with that specific switch.

Overall, making sure your power connections are secure and using good quality cables should lead to a smooth experience with the UGREEN USB 3.0 Switch Selector in your setup.
