I really like this search strip as I installed the inside of my RV the only problem I have with it is if you were using bulky transformer style plugs like that of a iMac laptop, charger or other big transformers, you will not be able to use the USB outlets in the center and I don’t know if that’s by design to limit current flow, but it sucks.

An absolute must for countertops used as workstations.

Style: 20W_USB-C, Size: 6FT

These were the best thing I did when we had to remodel and I added a large built in countertop. They are made well, and easy to install! They are very versatile since they are designed with both USB-A and USB-C ports along with the standard 110V plugs. I use these with my 3-D printers, laser engravers, computers, printers, and even a few coffee pots!

No issues, and no instructions.

Style: 20W_USB-C, Size: 6FT

No, you don’t need instructions, because the hole dimensions are in one of the photos. 4” x 1.73” is perfect. Plug it in and all of the ports in both that we bought worked perfectly.
