I have one too, but I used the amazon essentials version: http://smile.amazon.com/AmazonBasics-Portable-Power-Bank-000/dp/B00LRK8JDC

Kind of jealous of your extra 3000mAh though

I'm currently rocking the AmazonBasics 10,000mAh. I've been using it for about a year and it's awesome. I charge my phone, friends phone, lights, and gps. Hasn't faded with time, and the ports are all stable. It does not seem to lose it's charge over extended dead periods (not drastically at least). For the price, it's amazing.

I ordered the the charger that was mentioned by /u/phraust64 and got my code about a minute later.

Specifically, (10,000 mAh w/o cable).

This power bank also seemed to work, as it has the promotional tag, if anyone isn't interested in a game but would like a portable charger.

I have this one, EasyAcc 6000mAh, but this one AmazonBasics Portable Power Bank - 10,000 mAh is more powerful and also good, according to the review I read.

I do not think so. I think you can buy things sold by AmazonBasics tho.
