Chanzon (10 x Male) 12V DC Power Connector 5.5mm x 2.1mm 24V Power Jack Socket for Led Strip CCTV Security Camera Cable Wire Ends 10Pcs Plug Barrel Adapter

These are well made connectors that I bought for replacing the power supply connectors used for my LED experiments. I deducted a star because not all the barrels have the same amount of hold (friction/tightness). They vary on some connectors.

These are very easy to work. They have a solid connection and no slop when in use. Ive built a bunch of extensions for my multimeter and for my power supplies. Makes change overs so much quicker & easier.

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.

really easy to use and figure out

Was exactly as described. Great adapter for the price.
