Product Description

Style: 2000 MAH - B

The UniCharge 10000 is a high capacity, aesthetically beautiful, portable power supply. The Power Bank will charge practically any device - iPad, iPad 2, iPad3, iPhone (3G, 3GS, 4, 4S), iPod (all generations), Galaxy Tab, Android, eReaders, Kindle and many, many more. Simply connect your device to the Power Bank via USB cable and that's it! The Power Bank has 2 usb input ports so two devices can be charged at the same time! This is unique to the Power Bank - no other portable power supply/battery supports dual charging. The high capacity, 18000 MAH Polymer Lithium-Ion battery provides a huge amount of portable charge - enough, for example, to charge an iPhone 4 from empty up to 10 times! And it does this whilst maintain a slim, sleek, ultra-portable design. The display on the beautiful mirror surface, shows how much charge is remaining. The UniCharge comes with a USB cable - allowing connection to any Apple Device as well as micro and mini USB compatible devices. This cable can also be used to charge the Power Bank itself. Standard USB cables (i.e. the ones that came with your gadget/device) can also be used with the Power Bank.

Good customer service. replaced defective battery immediately.
Raj
At first glance, it seems like just an "off-brand" made in china product, and the packaging and manual even has chinese alongside english.

Style Name: 2000 MAH - B
After using this battery pack for about a week, I make the following observations, in order of personal significance:

1. Build quality: The battery pack feels, in a word, solid. There is no flimsy plastic deflection if you press on it and no creaky or uneven seams.

2. Looks: The pack looks great. Yes it is a fingerprint magnet, but it also wipes cleanly to a beautiful gloss to match most smartphones out there.

3. Utility: Very versatile. One port for smartphone and most usb powered gadgets, the other higher amperage port for more power hungry devices, like tablets. I've even used this to charge AA batteries with a usb AA charger. There's nothing I've tried that this won't charge. Also has a built in led "flashlight," but more on this later.

4. Convenience: This pack will charge easily with any usb charger. Standard micro usb connector means you won't have to go searching for a special cable to plug this in and charge it. This pack will also charge as you are using it. This may seem silly if you're at home, plugging this into your computer or power supply, and your phone into the batter, but if you ever use this with a portable solar charger, as I am with the Goal 0 Zero 19010 Guide 10 Plus Adventure Kit Nomad 7 Solar Charger & 4 AA Battery USB Power Pack, then it is great to charge while the battery pack as per the available light, while still being able to charge your device with the battery pack with reserve and stable power. The led light is also very convenient.

Here is my unbiased review of Anker Astro 2 8400mAh external battery pack:

Charge Efficiency: Its rated at 8,400mAh as it's capacity. The lithium ion battery may have that capacity but it's ability to charge other devices isn't so hot. I understand the Anker power bank needs power of its own to operate and conversion from 3.7v to 5.0v takes energy. I wasn't expecting 100% of 8,400mAh to fully charge into other devices totaling up to 8,400mAh. But I was expecting it to be efficient. I did 5 charge and discharge cycles (though it may not be necessary on lithium batteries but I did it anyways to calibrate it) then I went on with my test to see how much it can charge my Kindle Fire, HTC Evo 3d, HTC Evo, Kindle reader, and portable speaker. Yes, the devices I were charging were completely off to preserve energy for charging only instead of also powering it on. The first charge cycle it totaled 5,425mAh (64% efficiency), 2nd is 6,032mAh (71.81% ), and 3rd is 5,280mAh (62.85%). This means ~28% - ~37% of its 8400mAH capacity is unusable. I predicted at least ~20% of 8,400mAh is powering itself which is 1,680mAh and perhaps some energy is loss through heat. I concluded that the circuitry work on it is not as good and/or the lithium ion battery isn't of "higher" grade technology (ie. Panasonic & Sanyo 18650). It fell somewhat below my expectations regarding its most important function. However, I do have an Incredicharge I-11000 with 11000mAh capacity and it is about 65-70% efficient but much bigger in size. Perhaps this is the best we can get with portable battery technology. Another alternative is to buy a high quality spare battery(ies) specifically for your cell phone as 100% of it's rated capacity will be used to power that device.

Lots of devices need more than 1A to charge but there are very few battery packs that will put out that much current. In fact there are few 12V-5V converters that will do that. This battery pack has both the capacity and current output (2A) to charge pretty much anything that takes 5V - phones or tablets. I like the charge indicators and also the flashlight, for emergencies. The instructions were in both chinese and english - and they were adequate. I tried the battery on an iPhone, Kindle Fire and HP Touchpad. All charged correctly. Note that there are two USB outputs - one is limited to 0.6A and the other to 2A. Use the higher current for tablets.

Purchased the Anker external battery pack for my Samsung Skyrocket 4G LTE phone. The battery pack has already saved me on 2 occasions when I ran out of juice before the day was over! I even plugged up my ipad to it and i still haven't had to recharge it.

The only function of the device that can be improved is the flashlight. It is difficult to turn on and off..and slow to respond so I wind up pushing the on/off button multiple times not knowing if I'm pushing it hard enough. Once you get the flashlight to turn on, it is difficult to turn off and I end up having to push and hold on to the power button for a long time before it will respond. But, this is no big deal as I bought this battery to backup my phone, not use as a flashlight. I can always use the flashlight on my phone.

Overall, I am very happy with the purchase and would recommend it to anyone looking for a portable battery pack for their power hungry smartphone!
