zdyCGTime 90 Degree Angle DC5.5x2.1mm Male to Female Adapter 5 Volt DC Barrel Power Jack Charging Cable Connector for Tablet (DC5.5x2.1mm)(2pack)

Worked as expected.

Fit perfectly in the 12v 10a output port on my 600w solar power station. I use my power station as the main power source for my robot and gave me a tight connection adaption for my barrel Jack's. Well made and a tight flawless connection. I recommend highly

Bought these for my guitar pedalboard. A 90° angle before the plug adds stability. The walls on these are pretty thick so as you can see I shaved them down to size. Added some electrical tape to make up for some lost insulation. They work and fit great now.

Well made. Searches and searched and this was perfect!

The only caution I would add is making sure that the power output of your AC/DC converter matches the power input required by the device. I was able to connect using this adapter, but the power wasn't sufficient.

Both my wife and I have Lectric XP 3.0 folding electric bicycles that we take camping with us. We keep them in a large plastic tote in the back of my truck. After a ride, I would remove the batteries before we placed the bike in the totes, then I would recharge the batteries back at the campground. Once, we almost left the batteries at the campground prior to a ride because we forgot to put them back in the truck. I did not like removing the batteries from the bike after every ride, and potentially damaging them transporting outside of the bike.I thought that a right-angle adapter placed into the charging port might fit in between the folds of the bike frame and still allow the charging plug to fit. Well, it works, after a ride, I just insert the adapter into the charging port then fold the bike. Back at the campsite, I insert the charging plug into the adapter.I can now charge the batteries in the bike while they are in the tote in the folded position.

These are excellent quality 5521 angle adapters. They have a solid inner barrel compared to some which have a "tuning fork" pin connection. They are a legit 2.1mm and NOT 2.5mm. (They will not fit a 5525 jack.) This is good as the connection is solid and reliable.The barrel length is 12mm before you hit the plastic. I've had some which are only 10mm, and, if you have equipment where the jack is even a little bit recessed, those fall out. These are plenty long and secure.My only comment is that if you EVER think you will need more than two, get these from Longdex (https://amzn.to/3TIpeno). They are 100% the exact same product just a four-pack for about a dollar and a half more. Those also come in a variety of other sizes, too, like these zdyCGTime angle adapters.

SHORTS, WINK OUTS, FIRES, PLASMA FIREBALLS not only possible but probable in very common cases during installation and use. My 5A PTC self-resetting fuse did not help much. If you don't use ANY other fuses use a 2-5A fast blow.Or be absolutely certain you unplug your power source, if only at the female end of this connector.If you study the photos very closely you can see why.I was thinking these things were pretty handy, if overpriced. Little loose maybe, 4 or 5 stars.Then I was tinkering around with my POE setup on the back of my HTPC. About when I started to wrap it up I thought I saw a little spark jump from the back of the chassis. Almost ignored it.Brushed it again another spark. Sometimes yes, sometimes no. Check the other one. At first I thought it was different. I thought one was wired backwards. Impossible right? No wires in there I bet, more like bent straws of thin sheet. I thought it could be polarity reversing for guitar stomp boxes too.A lot of them reset the system.I got some big ones too. In the end my PC refused to start if I held the connector in such a way as to guarantee the short.I determined that if the connector touches a metal surface at an angle higher than about 70 degrees, say during installation there's a hard short of the CENTER receiving sleeve to that metal surfacing. If it is grounded or even just bonded to other parts of the system, and it usually is, you'll get a sort of "ground loop". If it's not bonded it will be elevated to 12V.Don't misunderstand. The sleeve is "grounded" as normal. It's the potential for the inner pin/cup/sleeve that's the hazard because the sleeve is not recessed far enough behind the insulating plastic ring: "hot face" connector. Big no-no like ALWAYS! That's why 1/4" stereo plugs are "never" used for power: tip hits ground BOOM!. Sadly in fact 1/4 is used to carry speaker wiring for some stage gear.Used with a switching wall-wart or line rat of anything less than 5-10A (far over its continuous rating) you'll probably get lucky and the PS will wink out.At the other extreme, if you are fiddling around under the automobile hood or in a solar battery installation and don't follow best practices: say you attached directly to battery hot, if you get a bit of momentum behind it flopping it around, or forward tension into an aluminum block or something, I can almost guarantee you a large, hot flash of metal plasma if not a white hot flashbang of the thing all at once.In between are all sorts of use cases including older transformer DC supplies, old CATV 24V AC power supplies.. they usually do not shut off even when highly overloadedIt appears many plugs from this maker, or whoever makes these, suffer from the same problem.No more 5.5 x 2.1 sleeve barrels for me... I'll take 2.1 or 2.3 spade spring type. They often have yellow tips.
