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 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.

really easy to use and figure out

Was exactly as described. Great adapter for the price.

this connector works well once its hooked up - my only complaint is the holes for wires are tiny and too close together - I had to wrap tape between to keep the sparks from arcing - other then that they handle36 - 48 volts without burning

Works great!

Ive been using similar connectors for a decade, but recently they all changed to a new design that doesnt work with thin wires and doesnt hold large wires securely. THESE are NOT the same junk that is seemingly identical in every similar product listing... the openings arent blocked by the clamping strip, the barrel metal is thick, and the set screws seem not to strip out. If any of that changes as I use more of them, Ill update this review.

I needed a quick interface and this not only had the male but female WHICH turned out I needed both by accident. The battery backup for my CPAP said 5.5mm and this was the ticket. HOWEVER, the input for the solar charger was slightly smaller than the 5.5, more like 5.4 - I suspect they wanted to use a proprietary plug to sell their panel. I cut off one of their charging interfaces that fit the input and spliced it to my female plug, which in turn was one of the male plugs to the bare wires from the panel. Had some Harbor Freight shrink wrap and tradaaaaaaaa. works great. put some paired spares taped the underside of the panel for future problems and off to the races. DELIGHTED.

Easy to use.

I used these to connect a power cord to a Lithophane I made.

Just what I was looking for
