Ok

Wow......i had not really realized how much better these would be than the previous ones i bought from elsewhere. However, these REALLY are WAY better when i came to compare them. And no....i dont have any link/association with the sellers......they just really deserve to do better because they ARE better, is the way i feel, and i will use them again next time. The wiring is better and the quality of the jack plugs is better. Thanks!

PERFECT

I ordered these connectors more than once. They are very convenient and work on every camera I have used them on.

Works well good quality

THESE CONNECTORS ARE SO HANDY WHEN INSTALLING WIRING. I USED THEM TO PUT IN A BACK-UP CAMERA IN MY SUV. I BOCHED A COUPLE OF THEM AND LEARNED 2 THINGS. GET A SCREWDRIVER THAT FITS WELL SO YOU CAN REALLY TIGHTEN DOWN THE SCREWS. AND, IF YOU HAVE TROUBLE INSERTING A WIRE INTO THE CONNECTOR, GET A SMALL SCREWDRIVER OR SOMETHING AND STICK IT IN THE CONNECTOR PLUS OR MINUS OPENING (WHICHEVER YOUR WORKING ON) AND FORCE IT OPEN SO YOU CAN GET YOUR WIRE IN. TOOK ME A WHILE TO REALIZE THAT SOME OF THESE TEND TO CLOSE UP A BIT, ESPECIALLY IF YOUVE BEEN WORKING WITH IT A WHILE. JUST FORCE IT OPEN, INSERT YOUR WIRE, TORQUE THE SCREW DOWN AND IT SHOULD WORK FINE.

Get this and youll never have to buy other parts for most interconnections in this very standard size.

I made a hobby out of making LED strip lights at home. I purchase these items constantly. Thiis time around, I got a bad batch. I has more defective plugs (male and female) in this a=batch than ever before. this was also the first batch that allowed me to use either a phillips head or straight screwdriver for connecting the wiring. The other plugs only worked with phillips. I had about 1/4 of them I had to throw away. I will very careful when ordering another batch of connectors

Great product excellent wires excellent manufacturing

Found these at a good price and needed some decent quality DC 5.5x2.1 connectors for the things I work on (Lithium Ion, Lipo, LiFeP04 batteries, COB LED’s, Power Supplies, Fans, Power Banks, etc) and at first I was satisfied with the set. The adapters are handy but the terminal block is just of average quality. Only had one that didn’t work. I rarely used the male and female DC connectors but after a year I’ve begun to notice a pattern. Now that I’ve used half of them it seems like 50% of the male DC barrel plugs don’t have a connection to the ground. More than once I’ve added one to a project and when I’ve tested it I get nothing from that connector. I check continuity and the positive side instantly beeps but the negative side shows OL or sometimes some extremely high Ohm readings sporadically. I was about to hand off a 70W COB LED panel with an A123 12V 20Ah battery to my mom for a camping trip when I realised I hadn’t tested that part of the circuit (it’s wired straight to the battery as an auxiliary input/output since my parents don’t even know what an XT60 is. In a pinch they could halfway charge the pack up with a 12V power supply or use the battery to power a 12V device with a barrel jack.) Sure enough another failure. I cut this one open to test the components and the connection between the black wire and the back of the jack look fine but have no continuity. This would be the 4th one I’ve encountered and I’ve used 8-9 at this point. Chop em off and waste some quality 3:1 heat shrink I had used along with the time I spent soldering this to the silicone cable coming off the battery. Now I know to test these before putting them on and I’ll also be testing all of the unused ones I have as they are right now since I should be able to find the failures. QC fail. I’ll look past a piece or two in a kit like this but one of the components has a 50% failure rate and that’s unacceptable. Classic You Get What You Pay For. Guess I’ll buy something more expensive from a name brand manufacturer off Digi Key for the rare occasion I need to use these to accommodate the boomer generation.
