Bought two of these. Anker is pretty good quality. What we found with this model is that is DOES hold a large electricity supply, but it has very poor shelf life. That is, if I fully charge it, then keep it on my desk for a week or two without using it, it DISCHARGES completely. While in use, yes, it can power a phone or two quite well. But it is not reliable as a backup if it has been sitting around more that a few days.
EDIT:
Dec. 9, 2016: The seller noticed my poor review and felt that they wanted to help me out. They sent me another battery FREE, postage prepaid. It works perfectly-- good shelf life, not like the first two. When I told the seller, then they sent me ANOTHER one... free. So now I have two GOOD ones which do hold the shelf life, from a company who really cares about making the product right!

This battery pack is ideal for your purse, pocket or backpack and it is one of the most portable batteries that I have tested. It had good test results. This is an exceptional charger with a feature that everyone needs. The feature is PowerIQ charging technology for the charging port on this battery charger. That means that you can plug in any type of device and this smart port will set the charging current to match the maximum charging rate that your device can safely handle. The port is rated at 5 VDC and up to 2 Amps but in my testing I was able to charge and Apple iPad Air at 2.1 amps.

Many people don't realize that device manufacturers play games by wiring their devices and cables differently so that a charger that is designed to charge an Android device will not quickly charge an Apple device. Manufacturers like Apple, Samsung, Android devices and Chinese smart devices have different circuitry in them and if the charger doesn't match their circuitry they can charge at a much slower rate. The IQ port doesn't care what type of device you plug into it because it adapts its charging rate to match what the device wants by sensing what type of device is plugged into it. I was so impressed that I put together a video of the unit and the test results for your review.

The construction of this battery pack is simply beautiful. The exterior shell is glossy black. The battery weighs in at 4.23 ounces. The battery pack has one smart IQ output port that output 5 VDC at variable current to meet the charging requirements of the device you have plugged into it. It is called a Smart Port or an IQ port. It uses a chip to help select the proper current to allow the maximum safe charging current for the fastest device charging.

No wonder this is the top rated portable power bank. I've had this thing for a few months now and wow am I impressed. The charge that this power bank holds is incredible given its size! I use an iPhone SE and I've gotten 2 full charges out of this with extra battery to spare! It's obvious that the folks at Anker really care about giving you a quality product at an unbeatable price. The prices of these things elsewhere are insane. Before purchasing this I looked at Walmart and the ones they had at this price looked horrible. The charge cord was very sturdy and the carrying bag fits the charger and cord perfectly. I also love that it has a battery level indicator. I carry this with my every single day. Would recommend for literally everyone. There's not a smartphone user on this earth that wouldn't benefit from having one of these.

Hi,

This is my review of the Anker Astro E1 5200mAh External Battery. I have evaluated it for a few days to provide my personal review and user experience. For my test, I have used an iPhone 5s and iPad Air.

First Impressions:

This product arrived in a plastic cover wrap that protected the exterior boxing and cover which I appreciated.

Upon first look, there’s the top side which shows the Astro E1 picture. The front side provides a customer service phone number and e-mail to contact Anker if product support or returns are needed. The backside has the serial number for the product. The bottom side has the IQ technology brief summary to learn more about it.

In order to view the Welcome Guide, you have to tear to open the front side to reveal it on the opposite side of the cover. I didn’t personally like this idea because once you tear part of the cover up, it sort of dangles around in which makes it hard to put away. It would’ve been better to have the traditional method of including a small pocket sized Welcome Guide inside the box.

Inside contains the following information:

- 4 LED dots lit on the Astro E1 represent 100% charged capacity, 2 dots is 50% charged capacity, and 1 dot is 25% charged capacity.

- Anker provides a 30 day money back policy and 18 month warranty, which is something that I’m happy about. Most competitive electronic companies these days offer 18 month warranty, so I am glad to see Anker provides that as well. That gives ample time to evaluate the Astro E1 through many recharging cycles to evaluate for defects.

The cardboard construction of the box is sturdy and useful for shipment and travel purposes.
