Conwork DC Power Converter Plug, 10-Pack (5.5mm x 2.1mm to 3.5mm x 1.35mm) Tip Size AC/DC Adapter Barrel Plug Connector for Wall Chargers

Worked great to add an on off switch to my Roku. Wich gets hot even when not in use.

Does what it says it will do and works where I need it to

I miss Radio Shack, I could walk in with an example of what I need and they'd either have it or not. They have these connectors categorized with a letter system. I needed a size M. These adapters aren't what I needed but the cost of returning them is above their price, so I have them collecting dust in a drawer, in case I find a use for them. I don't know why manufacturers cannot standardize the sizes so problems like this can be avoided.

Good quality. Great for bench work where you need to switch between projects and need a different size connector.

Product is just what I needed

Arrived quickly. Will be able to put extra cord on my security cameras.

It fried my Rock64 boards.

Not what I was looking for but that's my own fault not the company's But still a good product
