Need External Battery & Charging Cables

What kind of cables do I need to buy? Just Normal usb 2.0 to Micro? I have thin cables and they don't charge at all.

Here's what I am thinking.
Would this even work?
VOJO TRIM

AmazonBasics
Omaker

I am thinking about this power brick. I've heard Anker's external batteries are really, really good.
Anker 1600 mah

Thanks, guys!
