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)

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.

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.

You get so many, Very tight connections Hole up well 12v 1amp draw

Not

I liked that it included a nice variety of parts to extend or make power supply connections. Wires are a bit thick.

Meets expectations.

For whatever reason I constantly need these things. Buck and boost converters, running stuff off old computer power supplies and so on and on. Easy connection to power supplies for all sorts of purposes. The connector is almost THE standard size for all wall-wart type power supplies, particularly the ubiquitous 12v variety. I used up a pile of these already and am delighted to replenish to stock.

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

Well made pigtails and jacks that I have had no problems or issues with. good value for the money.

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