With such massive capacity, in such a compact package, the Anker? Astro E4 is perfect for flights, road trips, or just any time you're away from an outlet. Enough power to go around. Marooned? In transit? Forget your OEM adapter? With the Anker? Astro E4, prolong your battery life multiple times, wherever you are. Holding enough power to charge a smartphone 3-6 times (depending on your phone's battery size), keep your gadgets going for days and still have juice left to share. Strong but never slow. In addition to capacity, the Anker? Astro E4 sports two concurrent, high-speed ports. So whether you're charging an Apple or Android device, you'll get the most out of your technology. We've also included connective adapters to ensure compatibility with most devices. Designed around the details. Just because the E4 packs a punch, doesn't mean it can't look nice. We went with a smooth, ebony finish to keep you traveling in style. Simple, unobtrusive features, such as one-touch status LEDs and a built-in flashlight, give you everything you need out of a battery without sacrificing aesthetics.

Really useful on long drives and flights.
I am not a light user. I don't understand how people with Iphones even function. My screen brightness is always up, consuming media-youtube, torrents (video), documents from work, Team Viewer controlling my desktop from mobile (lol), bluetooth & headphones-spotify, GPS-maps for transit times, and LTE. I read entire Kindle books on full brightness, I administrate online groups and am in constant contact with people, ect.
So, I went with this (It has a 3 amp output), and surprisingly it charges my device noticeably faster than my after market 2.5 amp charger at home. You will notice it. This is perfect because I am always busy, and only get 30 or so minutes at the most between my commitments where I have the time to plug it in. It would be good for someone taking city transit too. This is sufficient time to restore a huge portion of the battery, even for larger devices with an already large capacity like mine. Looking back this was the superior choice considering my usage and my device's battery design.
There is a lot more to say but I think the other reviews on here have already touched on it all.
Has been working very well for a few years now.
It isn't the smallest brick, but a good size for a laptop bag and packs a lot of power.
Holds its' charge well and charges an iPhone 4S quickly.
Only drawback is the on/off/setting switch is a thumb-sized push-button that can easily be activated when bouncing around in a backpack/bag.
Very good charger. Love the pouch for carrying it around.
I was immediately impressed with the solid build quality of the unit; it has a very pleasing weight and I feel very comfortable tossing it in my bag for travel. The glossy finish of the body does show fingerprints but at the same time makes it easy to wipe any dirt or dust and I feel the unit looks very sleek. It comes with a mesh protective pouch which I like because it allows the unit to breathe to avoid overheating, and you can see the 4 charge LEDs through the pouch. The capacity of the battery is really impressive; I'm able to charge my HTC phone several times before it runs out and it's fantastic if you need to run your E Cig on the go. The battery pack also has a small LED on the front that you can use as a flashlight which is really handy for camping.
My one complaint is that like most units on the market this battery pack does take quite a long time to re-charge; especially if you're using a low output charger like a typical PC USB port or small phone charger. I was needing over 8 hours until I switched to a more powerful 2A outlet like the ad recommends. That being said this is not a problem unique to the Anker battery packs I've had ones with less capacity that take even longer. All in all this is a very impressive battery pack and I would recommend it to anyone who needs one.
