I ended up getting Amazon.com: Anker® Astro3E 10000mAh Dual 5V 3A USB Output External Battery Pack Charger for Smart Phones, Android Phones, PS Vita, GoPro; iPad mini, iPhone 5 (Lightning Cable not Provided); iPhone 4S, iPad; Samsung Galaxy S3, Galaxy Note 2; HTC Sensa
works like a charm so far. its a bit bigger than i expected. you can carry it in your pocket but its like carrying around another phone if you do.

Does anyone know what the difference is between the Astro3E and the Astro3 (besides $10)?

Also, I'm curious...when/where would you use something like this? I'm asking because I think I want one (I want to want one), but between car chargers and chargers at home and office, not to mention that my battery life usually gets me through the day already, I don't know when/where I would use it.

I'm often at all-day events in gymnasiums, convention centers, halls, etc where there isn't an outlet readily available. During these events, I often use an external battery pack to power my N4 which serves as a hotspot for our N7. If I didn't have the external battery pack, I wouldn't be able to use the hotspot through the whole day.

And recently, I was in a hospital waiting area (family member in surgery). Again, there weren't outlets readily available. I don't know how I would have been able to sit in the waiting room for over six hours if I didn't have my N4 streaming videos, surfing the web, etc. My N4's battery wouldn't have lasted the over 6 hours of screen time that day. Granted, this particular scenario is a one-off or rare, but I was certainly glad that I had my external battery pack that day.

Personally, I use RAVPower® 10400mAh RP-PB07 External Battery Pack Charger.

I picked the 5100mah Anker charger from Amazon a few weeks ago and am very happy. It is a great size and so far I've never come close to draining it. I do notice that recharging the backup battery is very very slow.

I purchased a ravpower also because of the holiday sales, it was too hard to pass up.
