With all the uses for equipment that comes with a Wall Wart, plug in power supply, many companies have tried to come up with ways to make it easier to plug a lot of them in, it’s not easy. The problem is that you want the plugs turned the correct way and spaced far enough apart to get as many as possible plugged in.
I like the small Wall Warts that are meant to plug in sideways and I found the perfect power strip for them. They use standard wall outlets, three in a row, this provides enough room that I can use every outlet. The ones that space them too close together can’t do this. This one come from Tripp Lite and costs about $20 from Amazon.
