OK...So Anker was kind enough to let me test out this little Power Packed pistol, and this review is based on my opinion and that of a couple people in my house hold.
First off all lemme say. Im a dad with an ideal situation for testing. 3 kids and a wife. So I let them use it also and pretty much condensed their opinions into this review.
OK so now here we go. First of all the battery arrived in its typical Anker packaging. Which i might say is nice compared to many other Chargers I have owned, which tend to show up in a plastic bag, or plastic packaging. The only real negative to this(Really not a big deal), is the fact you have to tear the outer cover to get to the directions. I personally like having it there as it allows me to see right away whats in the box and its one less piece of loose paper. Included in the Box is a Micro cable (Always a bonus), and a pamphlet with some contact numbers.
The 18 month warranty is a welcome perk, and though i have yet to have an issue with any of my Anker products, its good to know they trust their products durability and construction.
So how did this lil Power bank hold up? Personally I own a Samsung Note 4 and I use it for emails, invoicing, phone calls, video conferencing, and a multitude of other things. If I drained my phone to just short of 4% i get a good one time charge to 100%, leaving very little for anything else. So if you are a heavy data user and do a lot of muti-tasking you might need something with a lil more juice to last you the day. However my girls own Samsung S5's and my Son an S4. They were able to get about a good 1 and Half charges from the Anker from just short of 4% also. However with a heavy user it might not last the day. And thats not the fault of charger, just the fact with HD streaming now and data demand its asking A Lot from what is still a lil work horse.
My Oldest is in college and really liked the idea of trying out this charger. Mostly i believe to avoid sitting on a wall and trying to charge her phone. She got really good use from it and was able to get a full days use out of it. The IQ charging capability was a plus, since she was going form 2% to almost 100% in the 2 hours of class while she let her phone sit. She did however get concerned as she said the charger heated up and she was worried that something was wrong. But that was a minimal issue.
My 2nd Daughter spends the day running around with my grandson and busy using taking photos and videos of him. Her biggest comment was, "I love how compact and sleek it is". She spend a couple days with it, in her purse, and was elated that she had it on day 2. As they had spent the day at the Zoo and as dawn came realized that her phone was almost dead. No worries tho, she just pulled out her Anker and it went right to work. Within 15 mins she was at 20 percent and it kept on working. I can only assume the IQ technology is true to its claim of giving a great charge. The one negative to this story, was that i had to ask for it back. She didnt want to give it up!!
Now last but not least is my 16y/o son, whom spends a rediculous amount of time on his phone, and between apps, music, streaming video and only God knows what else the 5200 had its work cut out for itself. Now it performed well, mind you he is in school almost 12 hours a day with after school activities. So the charger wasn't able to make it thru the evening, but that is not necessarily a bad thing. Considering how much juice he uses, and it still got him thru till the last couple hours That is saying A LOT, about this lil beast. Again his only concern was how warm it got. However the demand on the charger and its ability to keep a consistent charge still give it an A+ in my book.
So overall this lil beast performed very very well. I didnt bother testing it on any of my tablets since the demand on the Charger would have been asking a little bit too much. But with the Phones just recharging and letting them sit a good 90 to 120 mins you are gonna have 100 percent charge on everything from the Galaxy family and With the Iphone6. Charging while using the phone will greatly depend on the type of browsing you are doing. Streaming videos, or movies might not get you thru the day. However the casual user will love this charger, not just for its capabilities, but its construction and feel.

Reviews with images
Functionally simple.
I was given this particular product as part of Anker's Power User Program for testing, so here is my unbiased review of the Astro E1 portable charger.To start the battery bank is a true 5200mah, unlike other chargers that claim more than what they are. For example, the Astro E1 uses two 18650 lithium batteries inside in parallel, typically these are around 2500-3000mah, so if you have a battery bank claiming upwards of 6000mah of similar size, then more than likely they are overrating their product. From previous experience, Anker has been honest about their battery ratings which I highly respect as very few companies seem to do so anymore.The packaging was very nice, as I've experienced with other Anker products. As far as what's inside, you do not get much, just the battery bank and a usb cable, along with a promotional/support card.The functionality of the Astro R1 is very simple, one button to check the status of the battery level, and if you want to charge your device just plug it in (no need to push the button). One of the best feature about this battery pack that others do not have is the IQ charging feature which automatically detects your device and changes its charging speed unique to your device for optimal charging time/speed.The Astro E1 feels solidly made in the hand, it has a good weight feeling as well as ergonomics. On the outside, there isn't much to see, 4 L.E.D.S show the battery level and a button on the side allows you to check the battery level.If I had to change anything about this product, I would probably include a carrying case with the set. I ended up using another carrying pouch that I got with another Anker product and it fits and matches it perfectly, makes me wish they had included one for this unit. Also, the usb cable that was included with the unit has the usb logo on the wrong side? For example, if you have the battery bank facing up (led side up) the usb logo on the cable will be facing the opposite direction. This isn't a big deal but it was something that I noticed. However asides from that, the unit itself is already highly refined and there is nothing that I would change at this point of ownership.
