There are lots of different ones for different purposes.
We are using this one in a couple of rooms. We like it a lot because it gets the dot up off the counter or table and doesn’t block the other socket. It typically costs about $15, but is sometimes on sale for a few dollars less.
We haven’t had any problems with the other socket being blocked, and we typically have a coffee maker plugged into it. But there might Not be enough space for A big wallwart unless you used one of the little extension cords we talked about before.
This particular model is well engineered and will hold up to 10 pounds. A lot of the similar lookalikes are flimsy and will only hold 2 pounds or so. So read the specs.
