Uber powerful.
20000mAh of power keep you and your gear going, and going – and going. Add 1000% more battery life to an iPhone, 600% to your large-capacity phone (like a Galaxy S4), or 130-300% to your tablet (depending on its battery capacity) – all away from an outlet. What’s more, the added energy efficiency gives you 10% more usable power than the previous generation and many standard alternatives.

Brilliant display.
Interacting with the all-new aluminum-cased beauty couldn’t be easier. The LCD simplifies everything – displaying the remaining power (with precision down to the percent), output, input and voltage selection.

    Beautiful design with fantastic efficiency test results! This battery pack is one of the most powerful rechargeable battery packs that I have ever tested. It is also matches the highest quality design and construction that I have seen in any battery pack. 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 brushed black anodized aluminum that looks fantastic. The battery is the size of a 7 inch tablet and it weighs in at 1 pound 1 and 1/2 ounces. It is assembled with machine screws and the overall construction is the best I have seen. The battery pack has three USB smart 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. It can also output 12 VDC at 1.5 amps and 9 VDC at 2 amps to charge many other higher voltage devices. You press the ON button and hold it for 2 seconds to select the 9 or 12 volt output voltage for specialty charging so make sure that you set it to match the needs of your device. This is important.This battery pack has enough power to charge an iPad 3 fully and in reality it could charge it 1.33 times according to my tests. I was able to charge my electronic devices for over 13.5 hours on a single charge of the battery pack which is amazing. During the testing the temperature of the battery pack never even exceeded ambient room temperature. I used the USB port to charge my devices during this testing. To start your device charging connect it with the proper cable and power adapter (You will probably have to use your own charging cable that came with your device.), set the voltage, if required, and press the battery pack ON power button and charging starts. The charging will stop automatically when your device is fully charged or the battery pack is depleted.The battery has a beautiful backlit LCD display that measure the battery’s capacity from 0 to 100% and there is a battery symbol shown that also has 5 bars for a fully charged battery. The display will also indicate which higher voltage is set. The battery display is not always linear to the amount of the battery’s remaining capacity and I think that is due to the fact that the circuit is measuring voltage and not true mAh capacity remaining.The Lithium Polymer battery can be recharged over 500 times during its life cycle and if you are a power user of a tablet, laptop or any electronic device that uses these voltages then this is the battery pack to own. It comes with an 18 month warranty. The unit comes with a powerful AC wall charger that quickly recharges the battery pack. The specs claim that it can recharge the battery pack in about 4 to 5 hours and in my testing that is what I saw when the battery was fully depleted. This product is one of the best I have tested and I rate it at 5 stars. If you are a business person or a student and have to depend on your tablet or laptop for long periods of time without the ability to get to an AC power source then get this battery.Items in the box:* Powerful AC wall charger adapter that will operate on 100 to 240 VAC at 50 to 60 Hertz.* The battery itself* A charging cable for your laptop and higher voltage devices that is 4.3 x 1.6mm to 5.5 x 2.5mm multi-voltage cable with pin connectors. This cable is 31 inches long.* An USB to Micro USB charging cable that is 28 inches long* A user instruction manual* A velour carrying bag* The 18 month warranty cardCharging my devices:I charged the battery pack fully before I started my test.Anker 20,000 mAh Battery Pack efficiency test:iPad 2 at 4% and the Anker battery pack was fully charged with 5 bars – 100%* 30 min iPad 2 at 14% – battery 100% 5 bars* 60 min iPad 2 at 23% – battery 97% 5 bars* 90 min iPad 2 at 32% – battery 93% 5 bars* 120 min iPad 2 at 41% – battery 89% 4 bars* 150 min iPad 2 at 50% – battery 85% 4 bars* 180 min iPad 2 at 59% – battery 81% 4 bars* 210 min iPad 2 at 68% – battery 78% 4 bars* 240 min iPad 2 at 76% – battery 74% 4 bars* 270 min iPad 2 at 85% – battery 70% 4 bars* 300 min iPad 2 at 90% – battery 68% 3 bars* 330 min iPad 2 at 94% – battery 66% 3 bars* 360 min iPad 2 at 100% – battery 65% 3 bars* 96% of 6944 mAh = 6666.24 mAhiPhone 5S at 21% battery pack at 65% with 3 bars remaining* 30 min iPhone at 56% – battery 62% 3 bars* 60 min iPhone at 91% – battery 58% 3 bars* 90 min iPhone at 100% – battery 57% 3 bars* 79% of 1560 mAh = 1232.4 mAhiPad Air at 38% – battery pack at 57% with 3 bars remaining…
