MOBOREST 12V 5.5mm x 2.1mm DC Power Connector Adapter, 12/24V Female to Female Power Jack Socket for Led Strip CCTV Security Camera Cable Wire Ends Plug Barrel -2PCS

Read my review on the 5 x 2.5 version. Love these things.

Nice

Solid product. Works as it should. Simple and easy.

Works perfectly!

I have an old turntable in an old stereo system. It was powered with a plug-in. Having a 12 v transformer, I used this to connect the two. I still have some old vinyl and this beat buying a new unit. Based on some of the reviews, this component seems sturdier than mentioned. The original output to the turntable was 7 ma, so it should last fine.

They work fine.

This item is just what I needed to hook up some wired cameras.

These adapters are well-made, and fit my equipment correctly. I am happy with the performance, and wish that they had not been sold in a package of 10. I doubt that I will ever use 10 of these but I understand how small a price difference it is between one and 10.

A couple years ago I bought a couple Plug Adapter Connectors from another supplier (dont remember brand) for relocating a surveillance camera using a pre made bnc cable extension connected to the existing RG59 siamese cable. Never had a problem with the power to this camera since installation. Last April I purchased these MOBOREST connectors to similarly extend another camera using bnc extension cable and I have had to make a gazillion trips to the attic to redo the power connections. The fixed connections last anywhere from a few hours to a week or more, but always fail. I have tried every possible way (other than tinning) to insert the stranded 18/2 into the connectors terminal slots and various levels of tightening the terminals screws and have used all three of these Moborests hoping that one might work. Based upon my experience with fine power conductors in a previous life, I suspect ambient temperature changes might have something to do with the connection failures. I really hate to cut into the extension cables power to make the connections with a simple splice but if this mornings fix again fails that will be my next attempt at a fix. FOLLOWUP -- Failed again. In examining the adapters slots, they both contain tiny bits of the AWG18 strands and in examining the conductor itself the several of the strands are broken. In playing with the conductor and the adapter on the well lit workbench instead of in the attic it is very difficult to insert the stranded AWG18 into the cleaned out slots. So, tried a different tactic. Took one short strand from a copper AWG8 conductor (appeared to be close to what a solid core AWG18 would be). and inserted it into one of the adapters slots. Had to force it a bit, but it did go in and the slots screw tightened it in securely. So, repeated this with the adapters second slot. Then used wire nuts to connect the solid core conductors to the stranded conductors. Reconnected the plug and it worked. If this power connection fails Ill edit again.

I used these on my motorcycle to connect my heated clothes to the 12 volt battery. It could not take the load. Not worth returning.
