Short Micro USB Female 2 Pin Bare Wire,30cm/11.8in Micro USB to Open End Pigtail Power Cable Easy Soldering,Micro USB 22AWG 3A for Micro USB Equipment Installed or Replace Repair DIY Cable(4Pcs)

I tried to use these to repair a portable Bluetooth speaker. They work as described, but unless you simply need a solid source of power, repairing electronics that regulate the charge is a bit more complicated than just two wires. Not the cable's fault.

Had a Raspberry Pi that had a broken power socket. Replaced it with this on and it works great.

This allowed me to check the output of USB solar panels before plugging it into a Camera.

Easy to solder to electronics. I attached one to a AA battery pack and it worked as intended.

The USB micro pig tall cables are of good quality and are about 11.8" long. You get 2 male and 2 female Cables with this package. The cables are made of 22AWG stranded wire and have a rubberized shell and a very small strain relief. My use was for construction of various adapters and low current connectors for a few small projects. They worked well for those applications. The connectors would generally work well for most low to moderate usage environments.

Used this on my raspberry pi connected to my 3d printer using internal power supply of printer. One less wall wart to deal with.

Cables seem well made, heavy gauge wire, good insulation.

I did not wish to cut the solar panel wires to upgrade my Ring doorbell. This was an elegant solution that allowed a rapid modification, and it immediately worked.
