USB to DC Power Cord, [2 Pack] 0.25m USB 2.0 A Type Male to DC 5.5 x 2.1mm 5V Power Plug Connector Cable Power Charging Adapter (USB to DC 5.5 x 2.1mm)

Didn’t fully work for what I needed however it’s not the products fault. I bought a mini projector which when plugged into the wall it’s really bright however it has a second plug that you can plug a battery pack into so you can watch movies when your camping but the brightness isn’t that good, the specs from the plug were almost the same but the battery pack was just a bit short of what it required so I thought I would try using it to fake the device into thinking it was plugged into the wall but it didn’t work. If I bought a battery pack that had the exact requirements I’m sure it would work just fine. The cables that came still worked which I tried on some other stuff, they are well built and don’t feel cheap.

Works great… use it to power tiny video monitor off of a basic battery/power bar. No issues so far A++

Good.

This is a wonderful USB-A to power jack adapter cable. I have a powered speaker that I wanted to get power from a usb port on the computer and not have to plug in an electrical power adapter into the wall. So got this adapter cable to instead functionally use to power the speaker via the usb port -- and it fits and it works. Great price where you get two of these adapter cables as made by Yeworth. Thanks so much Amazon & Yeworth.

At least they fit and seem sturdy enough. Time will tell.

These are cables that require a definitive load on the device end in order for any type-C charger to work. These are simple cables with no built-in sensing chipset, so a lot of basic devices out there will not work with them.

Does what it says it does

I use this to power a micro-pc on my astrophotography rig. So it has sat outside overnight in the freezing cold and warm humid weather as well. I've had no issues with it and it continues to power the micro-pc nicely.
