DAYKIT 10 Pairs DC Power Pigtail Cable, 12V 5A 2.1mm x 5.5 mm Male & Female Connectors for CCTV Security Camera and Lighting Power Adapter

I purchased these so that I could covert a battery powered "CHEAP" record cleaning device. The cleaning device ran on 4 D-Cell batteries, and after about 20 or so cleanings the batteries would start to show weakening. So I decided to convert it to AC/DC power. These connectors work great, straight out of the package, connected the positive to red and the negative to red/black, corresponding to tip being positive. Worked on first power up. Since the device is rate at 5V 500ma, any 5V wall charger for a phone will work, heck I did not even realize I could now use it with USB power and the package I received has 10 male and female connectors, so I created a male to USB adapter, now I have one that runs from the wall and one that I can run from any USB port. I do not why I did that, maybe it was that I could. These are good connectors. Well made and even if they fail they are so in-expensive they are easy to replace.

I'm thoroughly impressed with this item! The construction and build quality are outstanding, and it's been a reliable product through frequent use. I would wholeheartedly recommend this item to anyone in need of a top-quality product. This is my honest, unpaid review, and while the price could be more affordable, I believe that it's a worthwhile investment for anyone looking for a reliable, high-quality item.

I read the reviews of people who had problems mine were 100% to the good. I build my cables differently than the guy with the video problems as I create a straight cable than attach a (4 way) splitter on the end.

2 of the female leads didn’t work. All of the males function normally.

Ease of use, value for the money and size are all perfect for my needs.

They work fine. Female ends seem snug.

These are rated at 5 amps and they will do that fine just don't put more than that through them.

I bought 3 packs of these, from the one pack I opened so far 7 of 10 male connectors have some kind of internal break on the negative side. Gently pushing (less than 15*) or twisting the base of the connector where the wire joins causes the negative connection to open somewhere (tested by putting a multimeter across the negative wire and the outer metal part of the barrel with a multimeter in continuity mode). One of the seven didn't have a connection even when straight and unbent. This makes it impossible to use for any application where the cord can be moved or needs to bend at all. That said, 5 of the 5 female connectors I've used so far work fine. Additionally, as other reviewers indicated, the male and female connectors sometimes have an exposed gap when plugged together. TL;DR: Poor quality control, More than half the male connectors in a single package were defective.
