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.
