Lsgoodcare 10Pack 5.5 x 2.1 MM 8A-10A DC Power Jack Socket Threaded Female Mount Connector Adapter with Dustproof Plug

I have several small items that run on 12VDC for my travel trailer, but no convenient way to power them. While the rig is winterized in the back yard, I'm adding these jacks in places I want to add LED lighting, Wifi routers, fans, etc. These are perfect for that use! I also bought a pack of plugs that match, and some in-line fuse holders for circuit protection. I'm mounting 2-4 of these on a hand crafted aluminum plate, soldering the connections and fuse holder and mounting them in places where the wiring is (overhead cabinet bottoms etc). Now instead of 120VAC wall warts, I just put a plug on the cord and plug in where needed, and leave the inverter off most of the time now!

Purchased these 5.5 x 2.1 mm jacks to use on my low voltage solar controller board. I think these jacks are typically used in security camera systems, so my application is a little different. I’m using mine in a circuit controlled by a 12 volt timer through a SPST switch that is wired to my jack. I chose to use these jacks instead of hard wiring to my load so I had connection flexibility with different lights. Since each of my low voltage lights draw less than 7 tenths of an amp these jacks rated at 5 amps work fine. I do wish the rating were higher, say 10 amps so I could use them with an exhaust fan (mine requires 7 amps). These jacks seem to be well built and handled my soldered connections just fine. Recommend

Using in solar power supply’s that I’m building. These work great for plugging in lights, or for charging from a lithium charger.

The rubber caps fit so tight, that they are very hard to remove without tearing the strap off. Except for that they work fine.

Excellent replacement connectors or new installs. Quality is way above average. I didn't use any of the dust covers, but they are there if you really need. I used the first to replace an old legs massage/stretcher device. Had to drill a 11.5 mm larger hole, but installation couldn't have been easier. Terminals take soldering very well and the connector is really sturdy. Besides the dust cover, it comes with washer a nut (a 14mm did the trick).

Perfect for what I needed

Using these in an outdoor setting. The nickel plating has held up over a year now with no staining, and the rubber boots keep the rain out. Not bad!

These are bigger, more robust, easier to solder wires to. I am ashamed of myself for not getting these sooner. If you are looking for good 5.5 x 2.5mm DC jacks these are it. Can probably find cheaper elsewhere but it is worth mentioning that the rubber stoppers were noticeably thicker (less likely to tear) than aliexpress ones I have bought in the past!

All works but rubber bung could be a better fit

Decent amount of Jack Sockets size 5.5 x 2.1 mm. Chasis mount with Dustproof Covers and at the current asking price work out at just 40p each...a real bargain. Good quality and a good price, what's not to like. Recommended.

This pack of power jack sockets are an absolute steal at a price of £7.99 for 20 pieces. They do the job, so I really can't complain and find them very easy to recommend.
