are these 2 way or can they only be used with plugs?

plugs only-you would hook up positive to red, negative to black. (or one wire to each plug)

These are made for the USA market- I would not use these outside America. The plug and voltage are all made for the North American outlets.

It can work for and outlet with the 2 screws but for me i could only attach it with one of the 2 screws. This is designed for a plug with two outlets and one center screw holding it on.

I did not find any information about this, but there are only two plug-in prongs on this product. You may want to do some research online in order to get a better clarification about the safety of this type of product.

Yes. There is room for the other plug if you use it on top. You can plug in the bottom outlet and use a 2 pronged plug on top, but not a 3 pronged grounded plug.

Yes. These are not connected via plugs, they are hardwired. You can connect more than one to radio.

yes, I am using one of them on a double outlet, and the second outlet is left accessible.

No. They are used to convert the actual wires of a speaker wire into a solid plug. More efficient and stable connection

The plugs can be set both ways. I prefer flush to the side behind furniture, and angled if you just want keep plugs raised off the floor.

I never thought about using it this way. The plug is removeable so it looks like it might be possible. I have not tried it to confirm though.

no. While you can use them, you can also untwist the plugs and insert a wire. First you have to strip the wire back about 1/4 to 1/2".

Both ends are 3-prong plugs. A 2-prong could be plugged into it but need a 3-prong wall connect.

Only one female plug end. To use two tools, you would need some sort of splitter.

It more than covers one outlet so that the other one is almost, but not really usable. If you are putting a non-grounded plug in the other one you can kind of bend and maneuver it in place but not easily. Count on losing the 2nd plug 90% of the time. That being said, I love these things. If you use them to extend the sound from a main system that has a subwoofer in it, your whole house gets filled with rich, full sound and you can balance it via Remote App (AirPlay only) all throughout.

No, you can plug in any way. It doesn't matter. There is not a plus minus marking. Not needed.

I have not used them yet, but looking at them, each will only use one outlet. You will still be able to use the other outlet.

I believe you can if you solder to the wires on the opposite end of the power plug. The problem I had was hanging them. Mine were inside of some sort of silicone sleeve. Nothing would stick to them including the 3m tape that was supposed to be used for mounting. I also tried 20lb heavy duty 3m outdoor tape and no luck. If I had realized this I would not have ordered them in the first place! They were not like strip in the picture on Amazon!
