USB 2.0 Female Pigtail Cable Extension Power Cable 22AWG 5V 3A -2 Pcs(0.3M)

Excelente producto

Easy connection to a USB-A to USB-C charging cable from a Ring Solar charger.

Just as advertised

CAUTION!!! This ruined a number of my devices. The red and black wires are randomly swapped! Red is always supposed positive, but on this it's swapped.

This is sold as a power cable. USB power is 5 vDC. For the majority of DC wiring, red is positive and black is negative or common. These are just the opposite. Be sure to confirm wiring with a continuity tester before connecting. As with many chinese components, these are probably seconds or from the reject bin.

It's a good thing I tested these before trying to put them to use. The polarity of the wires is backwards. Had I connected something to one of these, it would have been destroyed immediately.

lucky I didn't blow anything trying to troubleshoot tho. works well otherwise though.

Wires are backwards red negative black positive but worked fine if hooked up correctly.

Buen producto. Lo que necesitaba.

This was a great help and enabled a wired USB Device to be connected to a 6v terminal source

All items arrived quickly and in good condition.

Does not work even reversed polarity.. bad

This is a pair of 2 wire USB power cord cords with female USB A sockets. I had read that others had reported that the black wire was carrying the +5V DC rather than the red as you'd expect. However, you never know if this was a bad batch that was since corrected, so I tested with a USB tester and sure enough the problem persists. Cable works just fine as long as you wire it up correctly.
