I bought a two pack of handcranked lights for 10$ on amazon: https://www.amazon.com/Simpeak-Flashlight-Emergency-Rechargeable-Survival/dp/B01CS949OS/ref=sr_1_3?keywords=handcranked+flashlight&qid=1555159475&s=gateway&sr=8-3

I got them as a back up to my O-Light. I keep one in my Bugout bag and one at home (i prefer to not use my battery-powered ones unless necessary, these cheapos work fine for normal day tasks). Definitely not as good as battery powered lights and they are a little flimsy, BUT I have had them for two years and they have yet to break and haven't failed me yet.
