I have 4 identical devices each with their own low amperage wall wart, and I want to tidy up my power cabling. (They are more like laptop power supplies than wall warts, as they have an AC cable, instead of just a wall plug.)
I'm not any kind of expert on electricity, but I started thinking about power bars, and assume they must connect things in parallel. This made me think I might be able to cut the all the AC leads off the wall warts and join them together, to create one plugin source feed to all 4.
Is this dangerous, or is it as simple as it sounds? They are grounded, so I would be joining the grounds together as well.
