He Tek fans as the title says I'm looking for a good battery pack, Like most of the world I've been playing Pokemon Go and that game eats up the battery of my Moto X so I might as well get a battery pack. It'll also be useful when I'm low on battery when I'm out and about for other reasons. The only requirement is that it is pocket-sized (around the size of the moto X) I'm asking this because my search on Amazon has me deer in the headlights, I don't know what brand is decent and what brand is poop. Y'all's help would be awesome. Thanks.
The game really drains battery life in a short period of time. I've also been looking for a good power bank because we can't let the battery kills the fun. There's a good list of battery packs I found in this site https://www.top9rated.com/best-pokemon-go-battery-packs/
I haven't decided yet which one to choose, I just thought you'll find it useful.
What to buy? The biggest one you can deal with. More capacity > more 18650 cells in parallel = lower discharge current per cell and as such the efficiency of the discharge improves slightly, especially towards the end.
These manufacturers aren't going to be using any high discharge current cells in these, I'd make a guess and say most will be using Samsung's INR18650-26H these days for their 2, 4 and 6 cell banks with advertised 5200, 10400 and 15600 capacities, while the big 20000 packs will be using six of the Panasonic NCR18650-somethingsomething.
If I were to purchase a power bank right now, I'd probably be looking at the usual suspects, Anker and Tenergy, RAVPower and Aukey and so on and so forth.
Maybe I'd pick up this

But do stay away from the small cylindrical ~2600-5000mAh power banks, they have just a single cell so they're no good. Go for at least the ~10000mAh banks.
And in regard to the capacities, deduct at least 20% for the step up and step down inefficiencies.
And if your device and/or power bank doesn't have Quick Charge then make sure your USB cable is nice and thick!!
Preferably at least 24AWG and not longer than necessary.
If you have a 1 meter 28AWG USB cable you would waste 17% of power if the power bank outputs 5V 2A!
Right off the bat with a 10000mAh bank > 8000mAh for the stepup/stepdown and then down to 6600mAh because of a bad cable..
24AWG gets you down to less than 7% loss while 20AWG gets it down to 2.6%.
How do I know that? It's just simple math.

That is some damn good info!
That wall of info is why I love this community. Thank you guys a ton for the help I'll be making this investment as soon as I have some spare cash. My little moto X isn't a fan of my pokewalks/pokehunting.
