RockBros Cycling Running Light (Used) for sale. Used a few times, but I no longer need to charge devices during rides, so I'm selling it. You can connect it to other devices by taking out the built-in cable. Please check the images in the latter half of the photos for details. Please consider this item only if you understand that it is used. Everything in the photos is included. I travel frequently for work, so it may take a few days to ship. If you are concerned, please inquire about the shipping timing. Thank you.
