There's not really much to say about these. They connect two male 5.5x2.1mm (5521) barrel jacks together perfectly. I didn't see any excessive resistance/voltage drop with them in place, either. Quality is good but nothing to write home about, with a little of sprue on the plastic overmold. Nothing excessive, though. Each socket has a sort of basket-looking thing, like an inverted banana jack. It rattles when nothing is plugged in.They're exactly what I needed, and are quite inexpensive.

These are a must-have for extending or adapting 5.5mm power connectors like you find on a lot of solar panels, Starlink minis, battery packs, and many other low voltage DC applications. They work well, fit well, seem to be well made, and inexpensive. Well worth stashing a pack of them with anything you might possibly need to add an extension onto, along with the typical male-to-male cables that are much easier to find than traditional extensions for 5.5mm.
