CHANZON Female 10 Pcs 12V DC Power Jack Connector 5.5mm x 2.1mm

I sell automation equipment and I have a bunch of demo equipment that I use these on. I love these connectors because it makes it super easy to connect a 24V power supply 5.5x1.5 power supplies for quick testing or to do a demo at my customer. I have used a few different ones and found these to be the best quality. I also like that these can handle 5A.

You can just see and feel the difference in quality. Chanzon power connectors are so durable and sturdy. In the second picture I compared the chanzon connector with a power connector that came along with a power supply I ordered thru Amazon. The cheapy one is all bent up and I can’t even connect a male DC Power connector — so that one’s going in the trash. If you need power connectors, BUY THESE!!

I used to make different hookup leads for my little power supply. Worked great. Easy to connect wires.

great product. Highly recommend

The power jack works as intended the quality is good and at a bargain! I am very happy with the power jacks, I use them to power up devices that would otherwise be hard wired like my fish finders so I can update them in the house while they are put up for winter storage.

Giving 5 stars because these are quality parts BUT I did find something better if you’re like me and have pre-existing ends that you don’t want to cut or use other adapter for. Copy / Paste into Amazon the below and thank me later :) Brand: ESUMIC DC Power Female to Male Splitter Adapter Cable for LED Strip Light, 1 to 2

I used these (and their female counterparts) for connections between my 12 volt transformers and my balancing LiPo chargers that I use for 3S 11.7 Volt batteries. I was charging 2 batteries at the same time, putting about a 4.2 Amp continuous draw on the connectors for about 1-1/2 hours. I checked the connectors for heat-up, and found none. Some have commented that it is hard to get wires in. I loosened the screws a bit and stuck a scratch awl into the holes to push the metal shrouding open and the wires slipped right in. I like the fact that by design, the screws do not screw into the wires. They screw down onto the metal connector material, which in turn, presses down on the wire. That way, there is no damage to the wire from the rotating action of the screw. It would also be advisable to "tin" the wire ends to make them easier to insert, but I did not do that with the 14 Ga. wire that I used. It was a tight fit. The product description says 16-26 AWG, but I did get it to work with 14 AWG. These connectors are also considerably large and heavy. So you may want to use a different option if you need to use them in a tight space.

The product description is no lie! These are far better than some of the crap ones I've encountered. They are solid, and the set screws are well formed and lend to a secure bite from the screwdriver. They cinch down tightly without failing [unlike others I've used, that fell apart under the pressure]. High quality! Highly satisfied!!

Satisfait de ces connecteurs et font le job pour lesquels je les ai acheté.

arrivé rapidement bien emballé. Le produit semble être de bonne qualité. A confirmer au fil du temps. Pratique pour mon spliteur POE pour ma carte relais domotique connecté en RJ45 ( toujours plus stable que du wifi).
