DZYDZR 2PCS 1 Meter 2.1mm x 5.5mm DC 12V Adapter Cable DC Plug Extension Cable Male to Female Black, for LED, CCTV, Car, Monitors, and More (3.3ft)

Works good, seems like it was built good.

Was able to get this to work with my ring base station to mount it on the wall where my old adt alarm siren was. Cable was just long enough to reach the plug in my attic.

Two power cables, as you'd expect power cables to be. Not great, not bad, a decent pair of cables.

From tip to tip, the exact length of the cord is 40 3/16th inches - just shy of 40 1/4 inches.

Pretty convenient set up. I pretty much just needed the extension so haven't used the splitter but it appears to be of good quality just like the expansion.

I bought this mainly to cut, strip, and place a 12 volt led rocker switch between my power source and 12v fans. The inner wire was indeed 22 AWG and was easy to work with. The inner wires are red and black.

Works as described. No issues.

The splitter cable and the extension work well but the male and female terminal adapters are junk. The screws in the terminal adapters are very very difficult to turn making it excessively harder then it needs to be to tighten them securely to your wires.
