KooMall 1Meg Ohm Safe Grounding Plug for Wrist Straps, Anti Static Mat, ESD Sensitive Device, Earth Outlet Socket Adapter for Antistatic Bracelets Wristband, Ground Cable Cord Wire (1xStuds+2xJacks)

There's one 10mm stud terminal and two banana jacks. Each one is connected to ground via its own 1M resistor. This means if one of the terminals somehow gets a high voltage on it, the things connected to the other two will only be able to draw a small current.The only downside is the housing is a little bulky so on a power strip you might have limited access to neighboring outlets. Overall I am super happy.

Perfect and at a good price! I have several at various places in electronics lab.

Won’t fit in some extensions with close socket placement

More affordable than similar products from other sellers, and it works just as needed.

When you need to ground something such as yourself while installing circuit boards or Ics, this works well as it only connects electrically to the ground wire in a 3-wire plug and gives you a connection on top. It’s a bit large, very minor.

My use case for this is a little different than some, probably. I walk on a treadmill at my desk, and I make *a lot* of static. Recently it's been very dry and cold, and if I wear anything polyester, I'm shocking myself, my cats, etc. even when I'm not on the treadmill.So I got this to help tame the static and it works great. Tested wearing a polyester fleece jacket, petting a long-haired cat, and no noticeable static buildup.I also can connect this to my ES mat when I work on electronics, but mostly I just don't want to zap a cat.

So the two holes in this are meant to receive the kind of grounding strap plug end on cables that you'll see as accessories to "real" professional anti-static mats, designed for people working on sensitive electronic equipment. These are fairly small plugs with usually four little pieces of metal sticking out a bit for good contact inside the jack on the anti-static mat attachment that is meant to receive them.On the other hand, the market is now full of nonsense "earthing/grounding" cables, that for some reason are designed to plug directly into the grounding plug hole on a typical electrical outlet. Why these things are legal to sell when they have no resistor in the cable to make sure the grounding mat is not the shortest path to ground, I have no idea. Anyway, what matters is the plug designed to go directly into the electrical outlet ground hole is way too big (and solid) to fit in this properly designed grounding adapter that has a meg-ohm resistor inside.I just wanted a cheap, small grounding mat to put on the arm of my sofa, because I kept getting zapped by everything from walking around on carpet in my plastic foam house slippers. So I got one of the little mats that come with a "grounding" cable meant to plug into the outlet. Then, separately I had to order a real anti-static cable with alligator clips on both ends, after making sure that at least one of the alligator clips would come off to reveal the smaller grounding plug that will fit in this grounding adapter. Turns out both alligator clips would come off, but I used one to clip to the cheap grounding mat, and the other end finally went into this adapter.So that's the story of how to get an actually usable (and hopefully safe) inexpensive grounding mat for your seating area that will reduce the instances of you getting zapped by everything you touch when the weather is weird, and also should not make you the shortest path to ground when you are touching it.But, I would think the market would have room for an adapter like this that does provide at least one jack meant to accept the types of grounding cords that are designed to go directly into the power outlet, to make all the "earthing" mats safer to use. That sure would be handy.Oh, but one very odd thing about this adapter is that the plug meant to go in the grounding hole of the outlet is... too big. I had a major problem trying to plug it in, and basically sacrificed a short "liberator" outlet extender to plug it into. I don't expect to ever get it back out without breaking the relatively flimsy plastic shell of the adapter, with the grounding plug left in the liberator like a bee stinger. I can't recall ever having such trouble plugging something into an electrical outlet, where the grounding plug was the source of the problem. Usually it's the flat prongs that get hung up trying to go into a badly designed outlet or new outlet that hasn't been broken in yet. But in this case it was definitely the grounding plug that was slightly too thick to slide in or out without significant force applied (and some dielectric grease!). I was very surprised by how difficult it was. Shocked, you might say, if you were inclined toward puns.

Multiple static safe terminals , each independent with it's own safety resistor. Exactly what you need if you're thinking about something like this. This is it.
