ordered 4 of these for my arlo pro 2 rig to keep them powered at all times. The micro-USB ends are tight but provide a solid connection. I had to mount some cameras upside down because the cable lugs tend to get in the way if you tilt the cameras too far. However, the software settings allow you to invert the image to accommodate this, so no big deal. So far there are no problems. I will update if anything changes. Enquiry: I would like more cable length. From 6 feet to 20 feet.
