High quality adapter is, don't fall off their included rubber carrying kit. They connects to my 5.5x2.1 mm USBC to DC adapter cable snugly, and transmit enough USBC-PD power to use a 27-inch 19.5 volt 60 watt HP screen.

I bought this kit of adapters to see if I could salvage a UPS ATT had provided with one of their modems to provide internet service to me. ATT no longer provides the UPS routinely so when I was requested to replace my current modem with new one, the power plug from the UPS no longer fit. Since the cord from the UPS is hardwired on the UPS end I couldn't just replace the cord so an adapter was the only solution possible. I would have only purchased the one I needed but that option wasn't available. I found one that worked and my UPS is back on the job. Although it only powers the modem, it does keep my wifi connection up if the power goes down. And I've got a bunch of other adapters that probably cover any other adapter requirement of similar nature in the world.

I liked the many options of connectors especially since I have a few different items that the original cords have either been lost or ruined now I only need one just have to switch out the plug-in piece for what fits the equipment.

Arrived missing one piece so I docked one star. I haven't bothered figuring out which yet. Would be a nice coincidence if it was a 5.5x2.1 or 5.5x2.5, tons of those lying around. Bought this to connect various barrel jacks to a 10a variable linear power supply's banana plugs. Looks like it'll work out, pretty cool. Looks like the laptop charger tips for brands that typically require a certain resistance between a center pin and ground, those types all look bulkier than the rest so I assume they include a resistor of an acceptable value. I'll test 'em with an LCRZ meter later & update if I run into any problems.Would buy again... Mostly just to figure out what the missing piece in this batch was hehe

If you can't find the electric attachment for whatever you using cell phone tablet that weird piece of whatever you found somewhere this is the product to use you have to have your own adapter so pay attention to volts and amperage for your product if you have the right adapter this will be the right connector this is the product you want to get, I had a security camera bought off eBay didn't have the connector would have cost $50 to buy one from Sony I bought this put it on an adapter and saved 50 bucks, had a tablet didn't have the plug for it this one had it now I can use them perfectly this is what you want to get believe me I've been searching through Amazon all those choices as well the same product different description same picture different product they try to confuse you but this one is the one you want to get it's sturdy it's well-made it's not some piece of flimsy crap that we get tricked into getting this is the one

Bought this to try and trick my HP laptop. the plugs that fit into my HP laptop doesn't have the right resistor to make it function correctly even if it does plug in. Does nothing.I used a couple of the standard barrel jack ones out of this kit and they work fine. So sticking with 3 stars.

Although I've only used four or five, they were all for odd sized adapters that I couldn't find elsewhere. They seem to work great, at least those I have tried.

I needed a custom power cable, but with Radio Shack out of business, what to do?This assortment is a great value! It includes a heavy duty resealable pouch. The individual tips are not marked with their size, but they include a sheet of paper identifying each tip on the strip. Hence, keep the tips on the strip in the same order.Buy it with a 5.5mm x 2.1 patch cable male to male, and you have everything you need to make a custom power cable.There are plenty varieties of these tip kits for sale on Amazon. I chose this one because it had the most tips. There are also some kits that have less tips but also include a cable.You do not have to take the tips off of their strips in order to see if they will fit your application (it sure speeds up figuring out which tip you need).
