Anker Astro Mini 3000mAh Review
I recently received the Anker Astro Mini 3000mAh External Battery for free from Anker in return for my open and honest feedback...so, here it is!
Anker Astro Mini 3000mAh External Battery
The Astro Mini best served my purposes as I spent the last 2 weeks in the hospital visiting my brother. I used the Astro mini to recharge my completely discharged 0% Anker battery in my Galaxy S4.
After extensive testing, I have determined that the Astro Mini provides roughly 1900mAh or 73% of a charge that makes it to the battery in the GS4. Anker states in the manual that 30% of the battery capacity is lost to heat and voltage conversion...which would effectively make the battery 2100mAh. I found this to be relatively accurate, given the fact that the GS4 can also lose some of the charge capacity through heat dissipation. It's within the realm of possibility that the GS4 wastes another 200mAh of capacity in the charging process.
The Astro Mini is GREAT for use as an emergency backup battery! It consistently provides a 73% charge to my GS4. At $22 on Amazon, it's a great value as a quality external battery. It also comes with a short micro usb cable, a micro usb to Apple (up to 4S) adapter, and a quality bag to carry it all in. For my purposes, I choose to carry a backup battery in my pocket at all times. However, this external battery has come in quite handy on the few days at the hospital that I depleted both batteries and fits perfectly in my pocket in addition to my spare battery.
As a side note, I'd HIGHLY suggest that you purchase Anker replacement batteries for your GS4, as I did, as they most certainly outperform the Samsung factory batteries. NFC is fully functional with these replacement batteries as well.

I also purchased the Anker 18W car charger for my vehicle and it seems to perform far superior to any car charger that I've had before. I'm quickly becoming an Anker fan, after seeing and experiencing the quality of their products...and this is currently the only Anker product that I've received for free...I have purchased all of my other Anker products.
