I bought this for a thru-hike on the Colorado Trail. I am a bit of a gram geek, but this thing will give you at least 10 days worth of full from zero charges on an iPhone 5. I am in the process of killing my phone and charging it back from 0 so that I can leave feedback on the amount of times it will charge from 0. I will update in a couple of weeks once the Anker Astro E7 External battery dies. I use my iphone 5 for my GPS, music, maps, cell phone, guide book and camera as well, so I can justify the added weight of the external battery.
I have recorded the weights here:
The unit itself (Anker Astro E7 External battery) weighs in at 481g or 17 oz (1lb,1 oz)
The Anker charger is 46g or 1.625 oz.
The anker charging cable is 17g or .625 oz
The apple 1m "lighting" charging cable is 17g or .625 oz
The black bag that comes with the charger is 12g or .375 oz
I am going to use a ziplock quart bag (6g)

Total weight for the charging package is 568g or 1lb 4 oz or 20 oz.

The Anker charger will work charging the iPhone 5, so you can eliminate the apple charger from your pack.

The external battery has a small LED on it that can be used for light in an emergency. I would not eliminate my headlamp, though. There are 3 USB slots on the charger, so you can charge a friends phone too if you are feeling generous with your amps. All in all, so far--I would suggest this charger if you are going to be on the trail-outside of towns for an extended length of time. I have had 10-14 days between overnight hostel stays, so I believe this will be a great addition to the pack. It will take a good 12-16 hours to recharge the battery pack using the dedicated 10w charger.

This battery pack is one of the most powerful rechargeable battery packs that I have ever tested and it is rated at 25,600 mAh. It had good test results. This is an exceptional charger with a feature that everyone needs. The feature is PowerIQ charging technology for each of the 3 ports 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. 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 and it looks nice but it makes it a fingerprint magnet. The battery weighs in at 17.39 ounces. The battery pack has three smart IQ output ports 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.

So I purchased this as a soldier, with the needs of one, and I will be reviewing it as so. For weeks, to months I can be very far from any source of electricity to power my personal electronics.

I've done my best to treat this "power bank" as instructed and to unlisted information but general knowledge of batteries of this type; In doing so it has not failed me once.

However, this power bank is clearly made for light travel. While it feels like it is very well made, so does an expensive phone and I feel like it could take as much from dropping it or exposing it to the elements. I feel as though items of this nature are of the adventurers and should have at least some dust protecting and maybe extended rubber corners.

As for its ability to hold is claimed power and charging abilities I am extremely satisfied. My Galaxy S4 charges at the same rate as it would connected to the wall and after my first charge I had gone down to 3 bars but it took two more charges to go to 2 bars. This is a large capacity battery and take some time to charge from the wall so my expectations for my 20 watt portable solar panel weren't the highest but with mild sunlight I did charge to full (or near full) within two days sitting near the gunners hatch of my vehicle.

Once again I do want to say that this item is not meant for adventurers abuse so keep it in a large sandwich bag and pad it when you can. However, these things can get warm so do not leave it in a sandwich bag while charging or out in the sun because it can greatly damage it.
