This is my review of the Anker Astro Slim3 6000mAh but here is another review posted by Vectron http://xdaforums.com/showthread.php?t=2388894

Hey everyone. I just wanted to give a review on my experience with the Anker Astro Slim3 6000mAh portable external battery pack. I’ve had this product for roughly 2 weeks now and can definitely say that it is the perfect companion to the N5.

As we know, our N5 doesn’t have the greatest battery life when it comes to on screen time. I found myself having to charge the battery during the middle of the afternoon only after moderate use and then at night when going to bed. I have a handful of Anker battery packs but the reason that this particular one caught my eye was its thinness and the fact that it has a built in micro usb wire/plug. Also, the fact that this thing is rated at 6000mAh was the deciding factor that made me order it.

From the photos, you can see that the Astro Slim3 is very comparable (in all aspects) in size to the N5. It is a fraction thicker than the N5 (and I do mean a very small fraction as it is only .47in), a fraction shorter than the N5 and a fraction wider. Weight wise, it is just a little heavier than the N5, but then again, the N5 is very light to begin with. The battery is incased in a plastic like enclosure which feels very good and it also is a deterrent to fingerprints.

Charging wise (using the built in micro usb cable), this battery pack was able to charge my N5 from 20% to 93% in 60 minutes and to 100% in 72 minutes. I’ve tested this 5 times to make sure this was consistent, and it was. If that isn’t impressive, I don’t know what is! It has dual ports and each port is rated at 1A each. There is no question that this battery pack is capable of high speed charging. There are 4 LEDs on the case that indicates how much juice is left in the pack and it was able to charge my phone 2.25 times before needing a charge itself.

Pricewise, it was a little more expensive than the other brands out there, but as the saying goes, you get what you pay for. Bought it from Amazon for $38 ( http://www.amazon.com/gp/product/B00CEZJT2E/ref=s9_simh_gw_p107_d0_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=0T6WMDN41N069KZDC4BR&pf_rd_t=101&pf_rd_p=1688200382&pf_rd_i=507846) but it was still worth it given the specs and convenience. If these two things are what you are looking for in a battery pack, then this product is a sure bet.

Let me know if you have any questions about this product.

On to the pics!

Top view: almost identical!!!

This is when it is charging. You can see the 4 LEDs indicating the battery pack has a full charge and you can also see the built in micro usb cable that comes with it

Oh, one thing that I forgot to mention was that this battery pack has 2 ways of charging your phone! One way is to use the built in/attached micro usb plug that comes with it and the other is using your own micro usb plug. The second way will definitely work if you have a case!

From this pic, the right side is where you would plug in the micro usb cable if you can't use the one that is built in/attached to the battery pack.
