Way too heavy to carry in purse for all day sports event. I ended up going to wireless store and getting much lighter one. I hardly use this one because it is so big and heavy. But it works.

I haven't tested it yet. I guess I should. It is for a winter coat to keep warm longer than the 10,000.

I am disappointed, none of my OIS cords fit. There should be an explanation, or an adapter. I’m planning to return it!

I almost returned this. It's heavy and took 2-3 DAYS to charge the first time. I gave it a chance before giving up and I got several iPhone charges out of it. Next full charging too 1-1/2 days. That's still ridiculous, but rather than return and have no charger, I hope it charges faster each time. The red coating came scratched off at the plug even though it came wrapped and packaged as if new. I wonder if it had been returned once before.
