Plugged them in all around the house. Still monitoring to see the difference in my electricity bill.

The cord has the three prong grounded cord to plug into the wall outlet. There’s four grounded ac plugs as well as four usb ports. It was perfect for my laptop desk and wire is long enough to connect anywhere i go.

Highly recommend. Great purchase. These are super useful.

The bracket can be mounted under the desk or anywhere really. This comes in really handy because i do like to have access to the power strip at the front of my crafting table.

The high pitched whine is louder and fluctuates quite a bit more than when i got it. Sockets are so tight, once you plug something in, you have to pull so hard it pulls out the mounting screws.
