MILAPEAK (Real 18AWG 43x2pcs Strands) 10 Pairs DC Power Pigtail Cable 12V 5A Male & Female + 10 Pairs DC Power Jack Plug Adapter Barrel Connector for CCTV Home Security Surveillance (2.1mm x 5.5mm)

Perfect for making easy to connect and disconnect 2-way sources

First got them for Christmas lighting, and have found they work well with many other small electronic devices Ive designed and built.

Good product, excellent seller.

I didnt measure the wire size but everything seems really good. Insulation is heavier than I would like but not an issue. Connectors fit nicely. I havent done any measurements on losses or conductivity but they are working fine.

I use these for connecting various electronic devices to various DC power sources. The work well and there is a good variety of methods to use

I stripped some of the wire and measured the strands with a micrometer, and counted the strands under a microscope. There are indeed 43 strands as the seller describes, but theyre each only 0.113mm diameter. This equates to about 20 AWG or thinner, with an ampacity of 5 amps, not even close to 18 AWG. Ive gotten similar results on import red-black bulk hookup wire imported from the land whose capital is at geo coordinates 40N 116E. So its the typical result with random electronic parts from Amazon: no brand, no markings, no identifiable source, samples deficient, not to be trusted. For a final test I assembled a loop-back out of one pigtail receptacle and the mating plug screw connector, pushed 5 amps through that, and metered 290 mV at the pigtail. So theres about 58 milliohms in the receptacle/plug combination. The pigtail wire was hardly warm, but the connectors were warm to the touch. So I found theyre OK for 5 amps.

Cant beat it when they work as they thought they would. Would buy again !

If you need 5.5 x 2.1 DC connectors, look no further - This is the best deal to be had. High quality components, cant go wrong here. Making some customizable shop lights and these fit the bill perfectly! Highly recommend & will purchase again.

I just got these and have already put them to use power one of my soldering projects. I bought these with one end open so I could make my own connections: very useful. I also bought another set with both sides done with two female wire bolt down connections. You will always find a use for these and they worked fine for me.

Does what they are designed to do. Buy yourself a bulk pack of these and keep on hand for when you need them. Most recently I used one when I cut a power supply cable only to discover that the negative lead was not insulated, but was bare copper. So, chunked that PS and used another one with this pigtail to give me 2 clean leads to plug into my microcontroller.
