Battery backpack that clips onto the arm of the Unistellar eVscope 2. Should work with other models if they have the same dimensions of the arm that the eVscope 2 has.
This allows you to provide USB power to the scope that travels with the scope, so you don't risk a cable snag and breaking the USB power port.
I designed it to work with this Anker battery pack:

And this cable is the perfect length:
