    Beautifully designed product that works well! This is the most powerful battery pack I have ever tested! This battery pack is simply the most powerful rechargeable battery pack that I have ever tested. It is also 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 aluminum that looks fantastic. The battery is the size of a 7 inch tablet and it weighs in at 1 pound 4 ¼ ounces. It is assembled with machine screws and the overall construction is the best I have seen. The battery pack has a USB output port that outputs 5 VDC at 2.1 Amps. It can also output 12 VDC at 4 amps, 16 VDC at 3.5 Amps and 19 VDC at 3 amps to charge many laptop and netbook computers. There is a voltage switch to set the output voltage for specialty charging so make sure that you set it to match your needs of your device. This is important.This is the first battery pack that I have seen that has enough power to charge an iPad 3 fully and in reality it could charge it 1.3 times according to my tests. I was able to charge my electronic devices for over 10 hours on a single charge of the battery pack which is amazing. Nothing I have ever tested has even come close to the performance of this battery pack. 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, set the voltage if required and press the battery pack power button and charging starts. The charging will stop automatically when your device is fully charged or the battery pack is depleted.There are 5 LEDs to indicate the amount of battery charge in the battery pack. Power levels are indicated by:* One flashing LED is 1% charge* 1 solid lit LED is 1% to 20%* Two lit LEDs is 20% to 40%* Three lit LEDs is 40% to 60%* Four lit LEDs is 60% to 80%* Five lit LEDs is 80 to 100 %In addition there are three LEDs to indicate the voltage setting of the specialty voltage output. 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 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 3 hours.This product is 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 this is the battery to own.Items in the box:* Powerful AC wall charger adapter* The battery itself* A charging cable for your laptop and 10 different styles of laptops* A phone charging cable* 5 mobile phone charging adapters* A user instruction manual* The 18 month warranty cardCharging my devices:I charged the battery pack fully before I started my test.

    I got this larger sized external battery for use with my iPad knowing I could also use it to suit other devices if need be. It’s a relief that I can use my iPad without worrying if I can get through the day before it dies or having to bring around my charger, I know the charger is not that big but it’s a hassle if I forgot it at work or leave it behind somewhere so it’s just much easier knowing I can charge on the go. The battery itself is nice, thin and sleek, it is very aesthetically pleasing compared to some competitor batteries that come in a glossy block which get covered in dust and fingerprints.

    I own the logitech wireless boombox speaker for the ipad. It delivers impressive sound when it is plugged into the mains. Outstanding sound! I was blown away! When you take it off the mains, it runs on a rechargeable internal battery at a 1/4 of the power(5 w). So the booming bass goes away. I have been looking for a way to keep this unit running at full power when it is plugged into the mains and I have been looking at various options. Today I found one! Beleive it or not I found the only external battery that is able to deliver the required 12V/2A power requirement for my boombox run at full power without a main socket. This is the Astro Pro 2. It comes with many adapters to connect to various laptops and devices. But I am amazed that I did not even have to use an adapter plug to connect to the boombox. The battery power cord fits right into the boombox input. Amazing. I plugged it in and wola!! Perfect sound! And this battery is 20000maH and 74whr. This is a lot of power to run the boombox at full power (20 watts) for at least 6 hrs. I am planning a trip to Africa and I will go to the village and I plan to throw a party with my relatives. This should be wonderful! The battery will also charge my iPad to full capacity with power to spare! The shipping on this item was extremely prompt. I was surprised at how fast this unit was delivered. I ordered it just this march 16. I got it today!!Update 1:I just had to come back here and update this review after what happened today. I have never bought a product online and the seller sent me a personal email a couple of weeks later to check on how the product is working for me. Today I received such email from Anker Direct and it was not some automated email. They were following up and the sender wanted me to share how the product was working and let them know if I had any problems. This is amazing! It gives so much confidence that I bought a quality product. This product is amazing! This is wonderful and reassuring customer service.
