Banana Jack Ground Plug Adapter – Anti-Static ESD Grounding for 3-Prong Outlet, Universal Banana Jack Earth Connector for Wrist Straps, Benches & Mats, USA Plug, Black, 1 Adapter

I have been looking for something like this for years without success. Our test benches have solid copper bar we attach our ESD leads to for grounding. But in the field you may not have have this available. This plug plugs into any 120VAC earth grounded outlet and works extremely well for working on electronics especially any electronics that have any MOS devices including CMOS, CPU, GPU etc., onboard the PCB. These devices will be damaged or killed outright if there is any static charge applied over 50 Volts static. Since at a minimum the human body has at least 5,000 Vs on the skin an could easily be more than 100,000 Vs, exposure to these voltages can kill the devices or damage their junctions causing premature failure. This plug in grounding plug takes a banana plug input. The body appears to be made of glass-filled polycarbonate that is very ideal electrically and costs more to make. It is an excellent insulator and is perfect for supporting the metal ground terminal. I bought two of these and they work great!

Love this because now I don’t have to sketchy stuff to ground myself. Much easier.

I have my Roku remote connected to a Bluetooth transmitter so I can hear "Home Theater Sound" when I play anything on Roku. This was my problem: most of the house is carpeted, so we're always picking up a lot of potential static electricity as we shuffle through the house. Most often all it meant was annoying static shocks when we touched a door handle. But when the Roku clicker is attached the Bluetooth transmitter, the shock goes through the Roku remote into the Bluetooth transmitter, breaking the Bluetooth connection and doing who-knows-what to the internal wiring of my fancy electronics. I found a solution and this is half of it! This "StaticTek Banana Jack Outlet Plug Adapter" gizmo (both these things have such great names), has two plastic prongs that go down each of the hot bars in one of the electrical outlets next to the couch in my den. Now class, you must believe with all your hearts that plastic does not conduct electricity for this experiment to work. The metal tube that goes into the ground hole of the outlet is the real deal: it conducts electricity. That tube goes through the plastic tunnel on the outside of the adapter, and you can see the end of metal tube just inside tunnel. Know this, my young scientists and believe it with all your hearts: the grounding port of an electrical outlet takes electricity in, only. Electricity will never come out of it. Now to partner with this, I bought these fun, little colorful, "Body Static Eliminator Discharger" sticks. https://www.amazon.com/dp/B0792VB871?ref=ppx_yo2ov_dt_b_fed_asin_title All I do when I sit down on the couch, before I reach for Roku clicker, is I take a discharger stick and touch it to the end of the metal tube, accessible within the tunnel on the outlet plug adapter. I feel nothing, but a tiny bolt of lightning is visible within the colorful window of Body Static Eliminator Discharger Stick, and then my Roku clicker is safe from my touch. If you are frying your electronics with your own personal static, this might be a fun home science project for you to participate in, as well! (My excellent 1982 NAD stereo receiver is made so the case is grounded by the plug. That's the other way I ground myself. I touch a different colored discharger stick to one of the screws on the outside of the receiver box!)

This is a very handy item and I appreciate that it's rather a specialty device. It's nicely made and works just fine. My only gripe is that I think it's kind of pricey for such a simple minded gizmo. Oh well, everything seems to be too expensive these days....

I don't see any problems with it

Solid little grounding plug. Pros: Plugs in without issue. Easy to plug a banana plug into. Cons: Can't really think of any.

Great little addition to my bench and wrist strap. Simple device that does what it promises.

The plug arrived exactly as described. I use it to ground a household ethernet switch. Lots of lightning strikes here in Florida, and you can’t be too careful.
