Perfect kitchen wall outlet
Size: 3 FT, Size: 3 FT
This is the perfect solution for a kitchen wall outlet that is plugged into the unused second socket behind the refrigerator. Now I can leave my blender and food processor on the small countertop next to my refrigerator. So convenient! And also a good spot to charge my cell phone.

Perfect for hard to reach outlets
Size: 3 FT, Size: 3 FT
The quality of the outlet is good. Functions perfectly has two Usb 2.0 ports and one Usb C port. Charges as normal chargers do. It is easy to use and worth the cost. The tapes for the clips doesn’t work on cement walls so I recommend using the https://amzn.to/4hoc2Qe with what I always use to adhere to cement walls.
