In terms of price as well as size and weight, it seems like they are selling something worth 10,000 for 20,000. When I actually charge it, it doesn't seem to last even 10,000 ounces. The only thing I like is that it has an LCD that shows capacity.

Two or more devices cannot be charged at the same time. Display is defective. No action has been taken even after two weeks of requesting a return. Please do not buy crab seaweed until you are exhausted and run out of trash.
