Product Description

Color: Black

The all-new 2nd generation Anker® Astro recasts the possibilities of mobile power.

PowerIQ™: Full speed charging. Every device, every time.
Not all charging ports are created equal. Standard ports only charge Apple OR Android devices at full speed. Our solution? A smart port, powered by PowerIQ™ technology, intelligently identifies your device and speaks the language it needs for full speed charging - no matter your device.

Power through your day.
We packed 6000mAh of power into a candy-bar shaped pack ideal for grab-and-go use. What's more, we realized an energy efficiency rate 10% above previous generation Astros and many current standard alternatives. This energizing combination charges the iPhone 3 times and large-capacity phones like the Galaxy S4 almost twice.

Double take.
Chic and minimalistic, the new Astro may feel reserved at first. But, a friendly "shake" reveals its warm inner light to display the power level or begin your charge. Generous, cool, and delightfully intuitive, the new Astro is perfect for your next adventure, or just the daily grind.

For optimal use.
• For simultaneous, max-speed charging of your Astro and other devices, check out Anker's new 40W 5-Port Wall Charger or 24W Dual-Port Car Charger.
• Compatible with all Apple and Android smartphones, tablets and other USB-charged devices. The iPod nano, Asus tablets (not include the Nexus 7), the LG G2 and some GPS and Bluetooth devices are not supported.
• To ensure complete safety and best performance, we strongly recommend using your device's original cable, a third-party certified cable (such as MFI) or our included cable.

Customer Reviews

The initial charge was quick and it charges his phone in no time.
M. Butler
Product quality is very good, nice size, especially compared to other brands, like the feel of the somewhat rubberized coating on the device.
Lorin Klein
Size of this charger is just perfect, small enough to fit in a pocket, light enough to carry around all day.

This battery pack is beautifully packaged with a black rubberized coated case. The black rubber coating is slightly textured so it is not a fingerprint magnet and it improves the looks of the case and your grip. It is a powerful battery pack rated at 6000 mAh of capacity and the test results were spectacular! I put together a video of the unit and the test results for your review.

The battery weighs in at 4 3/4 ounces. The battery pack has one USB output port that outputs 5 VDC at 2 Amps. It is a smart USB port whose output current will never exceed the capacity of your smart device's current charging capability. The battery is extremely energy efficient and its performance is 10 percent or more above the standard performance of a normal designed external battery. This is because of the superior quality of the battery cells used and the advanced control circuitry within the battery.

During the testing the temperature of the battery pack never even exceeded ambient room temperature. To start your device charging you connect it with the proper cable and the battery pack charging starts automatically. To check the battery pack charge status you have to shake the battery and the LED ring lights up.

This product is outstanding and I rate it at 5 stars. If you are a business person or a student and have to depend on your tablet or smart phone for long periods of time without the ability to get to an AC power source then this is a good battery to own. This is good for those who travel a lot or camp out. Now you can watch your movies or listen to your music on those long airline flights. While this battery pack can put some charge into your tablets it is more ideal for use in recharging your smart phone.

After rolling out new 2nd generation versions of Astro 3 (3 outputs) and Astro 2 (2 outputs), now is a turn for Astro with a single charging output. While Astro 3 was very impressive with three outputs and 12000 mAh capacity, it was a relatively large and heavy device, which is expected. Astro 2 shrunk it down to 2 outputs and 9000 mAh capacity with a more pocket friendly footprint. Here with single output Astro and 6000 mAh capacity the size was reduced down to an awesome compact size which you can store even inside of a very small purse. But don't let the small size fool you - you still get all new 2nd gen design with every bell'n'whistle of Astro 2 and 3. So let's take a closer look.

Continuing with their environmentally friendly packaging, battery came inside of a neatly packaged box which contained a battery itself, a manual (always very detailed), and accessory box with usb to micro-usb cable and a mesh draw-string storage bag for a battery and a cable. Now let me tell you about the size of this battery - its is SMALL!!! Weighting around 130g and with a size of 90mm by 45mm and thickness of 25mm - it will easily fit in a palm of your hand where you can make a fist hiding it inside. That's how compact it is. With a new rounded design and smooth edges, the hard plastic shell is lined with a soft touch rubbery finish. You get one micro-usb battery charging port (1A speed to charge the battery itself) and one full usb smart output port for any Android or Apple device. The output supports a maximum charging speed of up to 2A. In my quick test with OEM usb cable I confirmed a charging speed of 1.5A using my Note 2. The speed will obviously vary depending on the cable you use, so keep that in mind and use usb cables with thicker wires.

Color Name: Black Verified Purchase
I bought this battery pack from prime with two day shipping. Th battery pack looks gorgeous and it feels nice and rigid. doesn't feel cheap at all. I bought this for my Samsung GS4 which has a 2600 mA battery. having 6000 mA on the battery, I can charge my phone from around 5 % to 100% using around 60 % of the battery pack. The shake to check works really well however, I use this battery pack a lot on the go around college and I noticed that every time I walk the battery will detect that it is shaken and it will light up every time I walk. I'm not sure how much energy is consumed every time it lights up but it didn't seem like it consume too much. I would like to see a physical button instead of a shake because it annoys me to know that it lights up every time I walk.

After a week of usage, the usb cable's plastic housing came off. It can still charge normally, but it was a let down to know that the quality of the cable is not that good. Amazon can't replace the item but can return it. Since it still works I didn't bother doing so because I use this every now and then.

Overall it is a great battery for the money. If you're looking for a nice battery pack and the shake thing doesn't bother you. This battery is for you.

Product exterior -
Main Unit - overall the finish has a great feel to it. A very smooth soft plastic that might show some smudges from skin oils if you look really hard but easy to clean off. It has a good weight to it considering it fits in the hand very comfortably. The ends are very glossy and while the end with the usb ports (input and smart) is perfectly clean, the other side with the imprint saying 'Made in China, model number' was a tiny bit scratched up but nothing really noticeable. It does say over here that input is 1A and output is 2A. Ironically the serial number is not listed on this side at all or on the unit. ****The serial number is actually on a the short charging cable. ***Important, for warranty purposes do not remove this sticker..... I admit that I don't like this because usually any large stickers on cables I usually cut off, and also because the serial number should be on the unit itself rather than just the microusb cable.
Microusb Cable - The microusb is a very good quality 1ft charging cable. Some people might prefer longer but fortunately it has the high-quality shielded ends that Samsung OEM Cables have. There is a plastic covering over the ends protecting the finish that you can peel off.
Carrying Pouch - an interesting sports-like carrying pouch that is double layered and has a closing elastic mechanism. The microusb cable does fit inside with unit while pouch is closed.

Description of use - Very easy to install. I simply connected the microusb input on unit to an Anker 2A USB charger (1A or higher is great). I found it was like 80% charged and it charged up to 100% fairly quickly. It works very simply and great.
