If you want Butter to work completely off-grid and without electricity, it can! Butter Boxes can be powered by a wall outlet, pre-charged battery pack or solar powered battery pack.
* **Solar Panel (with Power Bank):** Use a small solar panel to recharge your power bank. This is a good option to keep the box running continuously in off-grid locations. Using direct solar panel without a battery is possible, but unstable if the sun dips in/out.
