I love this charger but here are some tips for those who aren't techies...
#1: This does not come with a wall charger - BUT - if you have an iPad or similar device with a USB port, that will work just fine. Save the 10 bucks and don't buy one separately.
#2: You must push the power button to charge. I know, I know, it seems like a no brainer but I don't have to push a power button on my wall plug so it doesn't come naturally to me to think to push a power button to charge something.
#3: To re-charge the Anker, you plug the connector into the small port on the side labeled 'In'. I felt like an idiot for thinking I should plug into the USB slots in the front to re-charge the Anker but hey, the 'In' and 'Out' are the same slot on my iPad so why would I look for an 'In' and an 'Out' on the Anker?
#4: The Anker comes pre-charged... mostly. I ordered this rush for a trip and didn't have time to charge it before I left. It powered my iPad to 74% straight out of the box. Pretty awesome for last minute folks like myself.

Once again, I'm sure this is low-level 'no-duh' info but I know there are a few non-techie folks who might appreciate knowing this stuff.

This review is on Anker 15000 mAh black battery pack. This battery pack is a real powerhouse of energy and in my test results it performed extremely well in supplying a charging current to an iPad 3 and an iPad 2. It is also designed to allow you to charge two items at the same time. I also tested the battery pack charging and iPad 3 and an iPhone 4 simultaneously. It comes with connectors and other accessories that you need to make it more useful. I was also able to charge the battery and charge two devices at the same time using the battery while it was charging. (This is not recommended to do) You may need to use your original charging cables for some devices so take them with you if you need them.

It is a great power resource to keep your USB recharged devices operating on those long work or school days or while you are traveling. This battery pack is a powerful source of power and many people like me are power users of their smart phones and tablets and need a battery like this. If you are constantly using your phone or tablet then you know that they will run out of power sometime during the day or evening. If you are not near an AC wall outlet with your charger or in your car with a charger what can you do? It is especially important to have some way to recharge if you are traveling in a plane, in the middle of a school classroom or on a bus or train. In addition many of the newer tablets are real power hungry devices and it takes a lot to recharge them.

Here is a powerful battery pack with two USB ports. It can charge your tablet devices or charge your smart phone and if you want it can do both of them simultaneously. I charged two iPhones at the same time in my testing. One USB output is rated at 5 VDC and 2 Amps and the other is rated at 5 VDC and 1 Amp.

This unit provides a tremendous amount of power for phones, tablets and cameras when they start to run low. I have used it to charge my Samsung Galaxy Note 10.1 and Moto cell phone simultaneously. Both charged from near-empty to full with power to spare. This unit also makes a great field charger for GoPro cameras. My issue is with the poor type and location of the switch. The touch switch is on the large flat top of the unit and is very easily turned on by mistake. This would not be an issue, if not for the built-in flashlight that turns on and uses the on-board battery. When traveling power is a premium, the flashlight is wasting the precious commodity. Move the switch to the side and use a switch that does not activate so easily. Redesign the switch... This unit would be 5+ stars!!!

First I will state that Anker sent me this product to review for my honest personal opinion on the product.

I received the Anker Astro E5 in the mail just in time for a scheduled meetup with Ingress friends. For those of you not familiar with this, it is an Android phone based game that combines augmented reality and geocaching. The game is VERY HEAVY on battery usage on the Samsung GS2. During these meetups, I usually end up switching a battery out or leaching off of someone elses battery pack. So when Anker offered this to me for testing, I was all over it.

The pack came precharged about half way. As soon as I got it, I put it on to charge and it was fully charged within the 4 hour timeframe prior to the meetup. The device is charged using a micro USB port on the side. It did not come with a wall charger, which I found somewhat weird. What if I didn't have a USB option to charge it with? It did come with a USB cable that had multiple options for connectors at the end. I only used the micro USB for my GS2 during my review time.

The device is very well built. It has a very nice little LED flashlight which came in handy during the late night meetup while walking down the streets of town. The device shows it's charge through 4 lights on the device. When they are fully lit, it has that much charge (think 25% per light). When I started, all 4 lights were lit. I will say that my use of the external pack is probably different from many. I believe it is meant to recharge your device when it gets low. I personally use it as battery for my phone. So Ingress was running on my phone the entire time that the meetup was going on. We walked around town for about 4 hours or more.
