I'm using this one:

It's fine for charging my Nvidia Shield, iPod or iPhone and the likes.
But for tablets, I found it problematic.
For one, lots of tablets don't charge via USB but have some §&(/))=" proprietary connectors. (Let's hope, the EU attempt re. standard connectors will change this asap). And last but not least, most tablets simply consume too much power. You can charge your iPhone at least twice with such an external battery. But a tablet only can be charged by 50% or so...
If I take, let's say, my Nvidia Shield, iPhone and Surface Pro with me on a trip, a single external battery won't help much...
