Amazon: Anker battery pack sale

Anker makes some of the most popular external battery packs out there. They are running a great sale right now, so if you were thinking about picking one up, now would be a great time.! 

 The 10,000 mAh Astro E3 is on sale for $22 (Make sure to select the Black E3 to get the best price - the white is more expensive)

I use the older model of E4 battery pack and it has been a lifesaver!  These are excellent prices for such highly-rated battery packs.


Another even cheaper option is a sale on the KMASHI 10000mAh MP816

On Sale for $14, but you can use coupon code GOQL7EVL to get the price down to $9.49.
I've never used a KMASHI battery pack before, but to get a 10,000 mAh pack for under $10 is impressive.




If you're wondering which size battery pack to get, as a reference, the iPhone 6 contains a 1,810 mAh battery.  So on an iPhone 6, you'll get about 5 charges out of the E3 and about 7 charges out of the E4.
