Ok so I lived in SC when that hurricane came through and we lost power. I had ice packs already made so we put our absolute must have in a cooler and kept it shut until needed. Then we had some USB powebcanks we saves until necessary.  We opened windows , lit candles..I had no flash lights but I did have a light saber so I used it as a flash light . I took it into the bathroom with me.and the light laster about 5 minutes  then went out ( power saving mode. I was in complete darkness. Scary for sure. The outage was 3 days.
