ROMOSS battery bike frame mount

thingiverse

I mounted the ROMOSS 10000mah battery pack on my bike's seat post in a customized orientation that worked perfectly for me. Since it's designed to fit standard size 28.6mm seat tubes, I had no problem accessing the USB ports on the bottom side of the pack. The power button and charge level indicators remained easily accessible as well. To remove the battery from my bike, all I had to do was rotate the pack and slide it out. This setup has been working great for me, allowing me to keep my phone charged while on the go.
