We buy a lot of these and have not had trouble with any of them. Works well in temperature extremes, no issues.

Have a few devices that need a 2.5mm size connector, but could only find a wire that had 2.1mm connectors -- it seems nobody manufactures the type of cable I needed with 2.55mm connectors, but now I have the 3 I need for that, and 8 leftovers to sit in the bottom of my wire collection for an indeterminate amount of time.

For the longest time, I thought my 12VDC cables were faulty, since I could never find one that would work with my iOptron CEM40 astrophotography mount. I knew I had one, but could never figure out why only one worked until I realized it was a 2.5mm center post on the CEM40, not a 2.1mm. This adapter to the rescue! Not only does it work, but it works better than the straight cable itself - it holds the post of the CEM40 with more friction and is less likely to come out, and holds the 2.1mm power cable post with less strain, so it's less likely to come out, too. All-in-all, I'm 100% happy with the bulk pack of these adapters, since I know I'll need more someday!

Used 2 of them to hook into a Calix ONT and router to go from regular 5.5x2.1 mm jack to the 5.5x2.5 mm female jack the Calix have. Sufficient amperage rating for the Calix. Not sure why Calix decided to go with the 5.5x2.5 mm jack. But used these in conjunction with a Talentcell DC UPS that used the 5.5x2.1 female jack and cables that had 5.5x2.1 mm male jacks on both ends.

I bought these adapters because some of the small power stations I own have two different sized power ports. Why they have the input port a different size than the output ports, I am not sure but now I can use one wall charger for each power station and all my solar panels can plug directly into any power station. Ok, that is wrong... my Jackery has a totally different size like 8mm. But I charge it with the cigarette lighter power cord plugged into the 12v outlet of one of the other units.These adapters are big and bulky but sturdy - sheer they are not!
