Brilliant display.

    Customer Video Review Length:: 8:13 Mins

    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 card

    If you are looking for a good Lightning cable to use with this battery here is one released by Anker that works very well with my iPad Air and iPhone 5S.

    [Apple MFi Certified] Anker® Lightning to USB Cable 3ft / 0.9m for iPhone 5s / 5c / 5, iPad Air / mini / mini2, iPad 4th generation, iPod 5th generation, and iPod nano 7th generation

    External battery that works with the Galaxy Note 10.1, September 27, 2013

    This review is from: Anker® 2nd Gen Astro Pro2 20000mAh 4-Port Aluminum Portable External Battery Charger with 9V/12V Multi-Voltage Port and PowerIQ™ Technology for iPad Air mini, iPhone 6 5s 5c 5; Galaxy S5 S4, Tab 2, Note, Nexus, MOTO X, G, LG Optimus, HTC One, PS Vita and More (Electronics)
    Great product. I had a difficult time finding an external battery that didn’t cause a red x appears over the battery icon on the Galaxy Note 10.1. With other external batteries I was able to resolve the issue with an adaptor, but it’s great not having to worry about one extra peripheral adaptor. Anker’s USB output S, (which stands for Samsung), with circuitry designed for the Samsung Galaxy Tab worked perfectly! Hope this helps other Note 10.1 users!

    This review is from: Anker® 2nd Gen Astro Pro2 20000mAh 4-Port Aluminum Portable External Battery Charger with 9V/12V Multi-Voltage Port and PowerIQ™ Technology for iPad Air mini, iPhone 6 5s 5c 5; Galaxy S5 S4, Tab 2, Note, Nexus, MOTO X, G, LG Optimus, HTC One, PS Vita and More (Electronics)
    Anker is obsessed with customer satisfaction, and they are clearly achieving it with products that are priced very competitively and customer service that is prompt, thorough, and efficient. This is my 7th Anker battery pack purchase, though I have given four away as gifts. All units work great, but each unit has its specific “specialties” so read the description and specifications carefully to ensure you get the unit that is best for you. This is the first unit I’ve purchased that is recharged with its own AC power cord that comes with the unit. (All others are recharged with a common micro USB cable that is included, though you need your own USB power SOURE such as a computer USB port or an AC wall USB adapter. The wall adapters are available on Amazon for around $10.) THIS unit MUST be recharged from AC power which reduces its flexibility slightly, but the upside is that it recharges itself about 2.5 – 3.0 times faster than the other units. A 30 minute charge of this unit provides sufficient power to completely recharge my Blackberry Z10, so if you have limited time to recharge equipment, this can be extremely handy. It takes about 4-5 hours to fully recharge a depleted unit. As advertised, it charges all my 5 volt devices including my phones, Zune, electronic reading magnifier, Bluetooth devices, and other similar gadgets. Since it can charge 9 and 12 volt devices it also powers/recharges my portable DVD player (adding seven hours of playback time) along with just about all my electronic devices that can be powered with a 12 volt power cord designed for use while in a vehicle, including lights, games, radios, GPS units, etc. (This is beyond the stated design intent of the unit, but it works fine so long as you ensure the proper voltage is used and no more than 2 amps are required.) A generous assortment of tips/adapters is included to fit most needs, though one additional adapter that would be extremely useful is a 12 volt utility plug receptacle that would allow users to plug items designed for vehicle use to be plugged directly into the Astro Pro 14400 Power Bank. (I made one myself in about 10 minutes from components of “dead” electronic devices that I keep in a junk box for such purposes.) The user manual says approximately 30% of the power bank’s capacity is consumed in the operation of the unit from inherent inefficiencies of voltage conversion and heat generation. That’s probably a bit overstated, but it leaves the user with a “net supply” of more than 10,000 mAh for recharging other devices. It provides more than six charges from 5% to 100% on my Blackberry Z10. This unit would easily fit in the inside pocket of a suit but it too heavy for a shirt pocket. If you don’t need the versatility of the 9 and 12 volt options, I’d recommend looking at the Astro 3E (it’s about half as thick as this unit, and has a total 10,000 mAh capacity) or the Astro E5 with its whopping 15,000 mAh capacity and built-in emergency LED that provides light for hundreds of hours to outlast just about any emergency. Both the alternatives are recharged with the micro USB cord which gives them a little more versatility, but charging times and be 10+ hours. If you don’t need 5-8 phone recharges from your battery bank, then look at Anker’s line of smaller (and less expensive) units that are extremely portable and typically provide 1-4 recharges of your device. One of their smallest units will provide at least one full recharge for any currently available smart phone and is roughly the size of lipstick so it fits well in a woman’s purse. Just type “Anker battery” in Amazon’s search box and you’ll begin to see the extensive line of products they have available. Have fun!
