We lost power for 3 days after a tropical storm in Florida. The Crankoax kept our phones fully charged and provided continuous NOAA updates. The table lamp made our living room comfortable at night. Absolute game changer!

After surviving recent Texas winter grid failures, I bought two of these for our family. The 10,000mAh battery is enormous compared to flimsy crank radios. The hand crank works smoothly and the torch is super bright.

I pack this in our evacuation bug-out kit and take it camping in the Blue Ridge Mountains. The weather reception is crystal clear, the compass is helpful, and having solar + crank backup gives immense peace of mind.
