I never write reviews but I'm really upset about this as it was for my emergency bag. That does not work. waste of money. Took me a while to open it up and try. Doesn't charge any device. DO NOT BUY! Received a replacement, thought it might just be defective but no new ones came in the mail today and it doesn't work either! LEMONS

All adapters have barrel (round) shaped connectors. The supplied cable has a USB Micro B (square) connector. I bought it to use my power station to charge my electronics while camping. It didn't work that well. It is very unfortunate that such an obvious mistake can happen.

This is an amazing set of general purpose DC 5.5V BARREL adapters. I love the length of the cable and the 5.5 to USB-C, MICRO AND MINI ADAPTER. YOU have so many connectivity options to power products that lack original OEM power supplies and/or connectors. As a PHE repairer, inventor repairer, scavenger and recycler, I will benefit a lot from this product.

I bought this cable to make my LED reading lamp fully functional. This cable was expensive but noticeably heavier than the original, which became unstable after a few months of use. I also appreciate the clear dimensions, which helped me decide that this was the right plug size for the reading light. Recommended if you have a similar issue and want to upgrade.

I lost the charging cable from a very old cell phone (20+ years old) and couldn't find anything suitable until I saw it at Revain. So I ordered it and it was delivered to me the next day. Bingo worked! Now I don't have to buy a new phone and lose a payment they no longer have. They saved me $250 a year. Many Thanks. It's worth the price, which was a lot less than I expected for all the different uses.

I have a Philips Hue Bridge and don't want to use its bulky charger and it's literally one of the only options on Amazon for a 2.5mm jack. There were a few more, but they were all very short, about 3ft, so I couldn't reach my desk from the outlet. This works great, captures the Philips tone well and is long enough where I need it.

Just what I need to power my external DVD/CD drive. Worked with one of the additional attachments they provided. I appreciate that it comes with multiple attachments, making it useful for a wide range of USB and plug-powered products. Definitely recommended, but you should definitely check the barrel size of the desired fork. I expect this product will cover most of the bases, but don't assume it will fit your product until you know the size you need.
