Wow, what powerful battery!
By jjceo (jjceo@comcast . net)
Watch Video Here: http://www.amazon.com/review/RYFZV847UCOP2 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. The unit also has an LED flashlight in it for emergencies. It uses Lithium-Ion battery technology and carries a 15000 mAh capacity. It has five powerful high quality batteries rated at 3000 mAh each. This is a large sized battery pack and it weighs in weighs in at 10 3/4 ounces. This battery pack will fit easily into a brief case, back pack or a computer bag or a large purse. I have included a video of the batteries features and I hope it is helpful to you.
When I test a battery I do an extensive set of tests that fully charges the battery and then I use it to charge devices and make sure that it is fully depleted when my tests are done. I time each test and document the results as the test progresses. I then calculate the mAh of capacity that the battery supplied and I then calculate its charging efficiency. This process takes from 3 hours to, in very large batteries, about a day for testing. I don't take any short cuts or guess and every battery has these tests performed on it and documented. This is to assure that the battery is tested and it performs well. If a battery has performed poorly I then run the tests again to verify the results.
What's in the box?
* The Anker 15000 mAh black battery pack
* The battery pack comes with an instruction manual
* The battery does not come with an AC wall charger. Use the Micro USB charging tip for charging the battery. You can use a computer USB 2.0 port to charge the battery pack but it is 15000 mAh and it will take between 27 to 30 hours. The manual states to use a 1.5 Amp USB wall charger and it will take 9 to 10 hours but I recommend using a 2.1 amp AC wall charger if you have one.
* There is one charging cable for the battery pack or your smart devices. It is 27.5 inches long.
* 4 various smart phone and device connectors like a Micro USB plug, a Mini USB plug, a Samsung Galaxy Tab 30 pin plug and an Apple 30 pin connector.
* A nice carrying bag
This is a very good product and below I have listed its features and benefits as well as my test data for your review. Please take the time to quickly watch the video and if you have any questions send me a comment and I will try to help you.
The Anker 15000 mAh battery pack features:
* Powerful 15000 mAh capacity specification
* The unit is compact in size and weighs in at 10 ¾ ounces this is the smallest size 15000 mAh battery pack available.
* It is attractively designed in black plastic. The front has a push button for starting the charging of your device or to read out the battery's charged capacity using LED lights.
* It has LED lights that show the battery charge. When 1 LED is flashing the charge is 0 to 25%, 1 LED steady on means 25 to 50%, 2 LEDs on means 50 to 75%, 3 LEDs on means 75 to 99% and 4 LEDs on means 100%.
* There is a built in LED flashlight you can turn on the flashlight by quickly pressing the on button twice and you can turn it off the same way.
* I was able to charge an iPhone 4 and a second iPhone 4 simultaneously while charging the Anker battery pack. I am asked all of the time if this is possible and it is; but I would not recommend using the battery this way. You are charging it with 1.5 amps for example and outputting 2 amps which can make the battery get hot. If you have access to AC power then charge your smart devices with their own AC wall charging adapters and conserve the battery for times when you are without AC power. This will extend its usable life.
* There are two USB power output ports. One USB is rated at 5VDC at 1 Amp and the other USB port is rated at 5 VDC and 2.0 Amps. I could charge my iPhone 4 in one port and my iPad 3 in the other port.
* You can charge two items simultaneously.
* Press the ON button when you plug in a device and that begins the charging process of your device. It is recommended that you unplug your device when it is fully charged.
* The battery uses Lithium Ion battery technology and uses 5 high capacity cells rated at 3000 mAh each.
* The battery pack can be recharged 500+ times
* Warranty is 18 months
Test charging an iPad 3 to measure the output capacity:
Test results summary:
Start iPad 3 at 5% and the Anker 15000 mAh battery at 4 LEDs
* 30 min 13% and the Anker battery at 4 LEDs
* 60 min 20% and the Anker battery at 4 LEDs
* 90 min 27% and the Anker battery at 3 LEDs
* 120 min 35% and the Anker battery at 3 LEDs
I went to bed
The next morning the iPad 3 was 100% and the Anker battery still had 1 LED lit.
* 95% x 11560 mAh = 10982 mAh capacity used
* I used the cable and connectors supplied with the unit for my testing.
Test charging an iPad 2 to measure the output capacity:
Start iPad 2 at 63% and the Anker 15000 mAh battery at 1 LEDs
* 30 min 75% and the Anker battery was dead
* 12% x 6944 mAh = 833.28 mAh
Test results summary:
* Charging the iPad 3 = 95% x 11560 mAh = 10982 mAh charged.
* Charging the iPad 2 = 12% x 6944 mAh = 833.28 mAh charged.
* Total mAh capacity consumed was 11815.28 mAh/15000 mAh = 78.77% of the battery's rated capacity. This is an outstanding result! Not only was it a very powerful battery it charged my devices very quickly.
Here are some of the mAh charging requirements for common devices:
* iPhone 4 battery 1,420 mAh battery capacity
* iPhone 4S battery 1,432 mAh battery capacity
* iPad 2 battery 6,944 mAh battery capacity
* iPad 3 battery 11,560 mAh battery capacity
* Kindle Fire battery 4400 mAh capacity
* Kindle Keyboard battery 1750 mAh capacity
* iPhone 5 is 3.8 VDC at 5.45 Wh = 1434 mAh battery
* iPad 4 battery is 11,486 mAh 3.7 VDC at 42.5 Wh
* iPad Mini battery is 4490 mAh at 3.72 VDC 16.7 Wh
As you can see the Anker 15000 will fully charge a totally dead iPad 2, 3 or 4 because it contains 15000 mAh of capacity. You still have to consider the losses in the charging circuits of both the battery pack and the device you are charging. Energy is lost during the voltage conversion, used by the electronics of the battery pack and your device and by the generation of heat.
Anker 15000 mAh battery pack device charging real world experience:
* iPhone 4 or 5 approximately 8.32 full charges out of a fully charged Anker 15000 mAh Portable Power Bank
* iPad 2 approximately 170% of a full charge
* iPad 3 or 4 approximately 102% of a full charge
* iPad Mini approximately 263% of a full charge
* Kindle Fire approximately 269% of a full charge
* A normal estimated usable storage is 70% of capacity or .70 * 15000 mAh = 10500 mAh charging capacity available for your electronic devices.
* In my testing I was able to use approximately 11815.28 mAh of capacity or roughly 78.77% of the 15000 mAh capacity. This is an outstanding performance for this battery an especially after testing it on a power hungry iPad 3 and iPad 2.
This is a great product and deserves a 5 Star rating!
I received a sample product for evaluation and I promised to provide a fair and honest review.

Tips for the Non-Techies
By R. J. Atkinson
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.

Great source of power. Poor switch design.
By BWDscott
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!!!
