I decided to purchase these ports for a power box that I am building and wanted something heavy duty. I saw that these had good metal barrels and figured I'd give them a shot. I was unable to upload pictures but the testing that I did did not disappoint. These will comfortably pull 9.5-10 amps all day long without issue. After 30 minutes on a load Tester the barrel itself was barely warm to the touch and cooled in under 30 seconds to room temperature when power was turned off. For $10.90 for a six pack, that is a steal! Highly recommend for any power box builds whether you're withdrawing power or inputting solar into it! Duration: 31 minutes 12 seconds continuous Power supply output: 11.5 volts @ 9.55 amps Load tester input: 10.4 volts @ 9.51 amps Delivered power: 98.904 watts Total dissipation: 10.921 watts End-to-end voltage drop: 1.1 volts Female barrel temperature: slightly warm to the touch (41–43 °C) 18 AWG PVC wires: warmth barely noticeable Male pin temperature immediately after unplug: completely cool to the touch Cool-down to room temperature after disconnect: <30seconds Connector: 5.5 × 2.1 mm nickel-plated steel barrel jack Date of test: November 08, 2025

Both make and female ends fit snuggly and work great to power my 8-port Netgear switch inside an outdoor enclosure for a light show. The wiring feels quality and it bends easily allowing these jacks to be used in tight spaces. I used a 13/32" drill bit and the hole was tight enough to screw the jack directly into my plastic case.

These work great for 48v battery’s over been using them for months now work great and last awhile

These are solidly built, would recommend. If you're designing a 3D printer enclosure for this, 12mm seems to be the sweet spot for your hole diameter. I'd say the only con is that you need a lot of clearance for the female receiver since the leads are heat shrinked and stiff, but you could always cut the leads off and solder on your own.

Easy to install. Nice fit. Are sized as promised. I do wish a split-ring locking washer was provided (like many similar devices), however, not a deal breaker.

Works great nice and compact great for any diy

I needed a new power input on my Casio keyboard. I bought this set of six power jacks for $10.90. They worked great. The Jacks use what seems to be high-grade steel with precision threading that was easy to work with. When mounted it was very sturdy. Transmits power.

Excelente!!!

The nuts in the kit do not match the size of the connectors, you can throw them away
