 +===== Tear down =====

 +
 +  * The case would be water resistant, but would not survive being immersed in water, it is not water proof. 
 +  * The battery in my sample is rated at 4000mAh, not 8000mAh as stated (and printed on the case).
 +  * The solar cell is not really a practical way of charging the battery.  In the best conditions, with 100% efficiency it will take 40 hours to charge a 8000mAh battery.  So under the best condition, with 8 hours of strong sunshine a day, it would take 5 days to charge.   Perhaps if you were marooned on a desert island near the equator, it would be useful, ... if there was also cellphone coverage there ...
