It’s blue. That apparently was the most important feature. However, it’s also got 2 outputs to charge a couple of devices simultaneously, and enough capacity to do it a few times before recharging.

This is a small size and light weight power boost. It works very well and I do like it.

Would have been useful to know the weight - i think I'd have bought two 10000s instead

This battery is heavier and larger than my phone, but it quickly charged my phone and could have done it 3 more times easily. It has a nice feel and no sharp edges, making it easy to carry in hand or in a bag or backpack pocket. I only just received it and used on a 4-day getaway, but I am hopeful the battery will recharge multiple times and last a long time.

It's doesn't have the C port

Love this

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.

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

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

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.
