I am very impressed with the quality of these. I think you will be hard-pressed to find anything missing here. These likely have everything you will need. This is a large assortment of adaptors that fit standard 5.5mm barrel connectors. Excellent value for the price.

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.

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.

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

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 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.

These plugs work exactly as advertised, and the detailed description of the item is very helpful and accurate. It does not contain every plug you might need nor does it handle polarity differences on it own, but this is a great set of adapters that are just as described. It contains the majority of common plugs, but most importantly just exactly what is contained is clearly described. I cannot comment on durability yet. Good value for the money,
