This is a perfect product for anyone who travels or works long days. This powerful battery pack can charge your smart phone or extend the use of your smart tablet. It is beautifully designed, small and portable. It uses two top of the line Samsung 18650 power cells which will provide years of recharging capability. These are the same style of batteries used in many portable computer battery packs.

What I like is that the unit is priced well and it is so small and portable but can really carry a lot of power. You could recharge most smart phones from 2 and up to 3 times with this power cell. I have included a video of this review and I hope it is helpful to you.

Please note that the unit comes with two cables and you can charge the battery with your PC or with the wall AC adapter. The wall adapter will charge the battery pack twice as fast at 1 Ampere DC because your computer's USB port is limited to 500 mADC. The charging port requires a USB micro-B connector that comes with the unit.

The output current to charge your devices is limited to 1 Ampere but it still was able to charge my iPad 2 and iPad 3 which normally charges at 2.1 Amperes. Please remember that after you connect your device to press the power pack's "On" button one time to start the charging. Make sure to take note that your electronic device indicates that it is charging. The blue LEDs on the front that flash when the unit is charging or stay on to indicate the battery charge level are very bright. I had to cover them up at night as to not light up the ceiling of the bedroom, especially when they were flashing. (Very distracting)

Here are the product features:
* 5600 mAh capacity
* Compact and portable weighing in at only 4.

In terms of physical size and weight, I'd place this at about the same weight as a cell phone and a bit larger than a couple of 9-volt batteries stacked on top of each other. You can easily wrap a hand around it, or slip it into a pocket, and the weight is enough that you'll know it's there.

The main thing you should care about with a product like this is how much of a charge you can get from it. My cell phone is the Samsung Epic 4G, and has an extended battery installed. This pack was able to charge it from around 25% to 100% over an hour or so. It did that twice, and charged my brother's Motorola Droid once. Then, it provided maybe 20% of a charge to a 'New iPad' (a.k.a. an iPad 3). For the size, weight, and price, I was pretty impressed.

There are two "tricks" to using it. The first is that to initiate a charge from the battery to your device, you need to connect the cable and then press the button on the front of the battery to start the charging. Press the button twice quickly (like a double-click of your computer mouse) and the flashlight turns on (or off). The flashlight is a single, bright white LED and works well enough for basic needs.

I haven't measured the time it takes to charge the pack itself. When I've used it, I've just plugged it in and charged it overnight.

The charging port takes a standard micro USB cable. For my phone which charges with the same port, that's perfect. It means that all I need to carry is the wall plug and my normal USB charging cable for my phone to use it on the go. (Plus the iPad cable if I plan to use that.) The battery comes with a bunch of other plugs that, honestly, I will likely not use.

This little power saver is a great idea. I often worry about battery life and running out in an emergency. This little product is so easy to charge, and use. It holds a ton of power to recharge your cell phone and it is very portable, but also very well built and sturdy.

I never worry about my cellphone running low in a power outage or an emergency. I have two of these now and have recommended it to several of my friends! A well made, quality product that could save a life and also give you peace of mind for any emergency!! 5 Stars for sure!

Love this charger. Provides about 2 full charges and then some for my Iphone 4s. Although the description lists that it is a databank for the Iphone, it doesn't come with the adapter for the iphone. There are many others that I will never use though! It just has a regular USB port so you have to use your own cable.

This is a great product that comes with extra adapters and is great for charging the phone on the go. You should know that you have to use your own iphone cord to charge apple products. Apparently it is due to patent and I appreciate the product overall, but this was surprising and I was worried that it wasn't compatible with Apple products at first.

TLDR:

Love it. Charges my Google Samsung Nexus phone multiple times. Works with latest gen iPod.

Full version:

I was a little skeptical; I had another external battery (Duracell branded) that inexplicably would not charge my phone. It worked with my iPod, so I thought it might be my phone, but I decided to give this a try.

This charges my phone (and my iPod) with no problem. I actually purchased one for me, one for my partner, and we both love them. I was recently on a business trip in a suburb of a major city, and had to frequently take 1+ hour train rides. If I forgot to charge my phone, this handy-dandy device could recharge on the fly.

It is relatively compact and attractive. The LEDs indicate when it is being charged or when it is charging something - which is very convenient if you want to ensure it's doing what it should.

It comes with a handy built-in LED flashlight. This was great on my super-long plane trip, when I was fumbling around my bag for something.

It will charge my phone about 2.5 times, which is just freaking amazing. It is *so* handy to keep around.

Cons:

The carrying case, while a nice idea, is too tight to fit the connectors and feels cheap. I almost wish it wasn't included, because it makes me think how awesome a nice carrying case would be. The connectors and cables are, inexplicably, white. The main device is black; I can only assume this is due to iMania, but then why not make the whole thing white?
