Anker 2nd Gen. Astro 6000mAh External Battery Charger with PowerIQ™ Technology

Anker 2nd Gen. Astro 6000mAh External Battery Charger with PowerIQ™ Technology

9901 Bluetooth speaker

Product Description

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

Compatibility maximized.

Not all charging ports are created equal. Standard ports only communicate effectively with particular devices, like Apple OR Android, often limiting their recharge rate. But with PowerIQ™ technology, each port intelligently identifies your device to speak its unique charging language. So plug in any brand or model and enjoy compatibility that doesn’t limit your charging speed.

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

- 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.
- For simultaneous, max-speed charging of your Astro and other devices, check out Anker's new 25W 5-port wall charger or dual-port 24W 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.

  • This charger has charged my iPhone 4s 3 time to 100% from around 30% and had about 25% more to go on the charger. Very satisfied. The only reason I gave a 4 star rating is because the indicater light come on everytime you move it.

  • A great charger, at an incredible price point.Verified PurchaseThis review is from: Anker® 2nd Gen Astro 6000mAh (2A Output) Portable Charger External Battery Pack with PowerIQ™ Technology for iPhone
  • This device works great - it has a great reputation and deservedly so.The build is very rugged, and while it felt a little heavier than I thought it would, it is still light enough to carry in my pockets! In fact, I've had situations where I've been charging the phone and both are in my pocket without it sticking out too much.I get about 5 charges out of it before I have to re-charge the unit. Granted, I don't let it get under 20%. The charge is surprisingly quick - and is about the same as the on the wall charger that comes with my iPhone.To check how much juice the thing has, you shake it and a dial lights up. It is a very nice feature.Pros - great size, good construction quality, simple to use, extremely quick rechargeCons - only one usb can be charged at the same time.

Customer FAQ

Q1.  Can I use USB cables othan than those provided with my Anker external battery?
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.
Q2.  Does it work with the new iPhone 5s, 5c?
Yes. But the Apple connector is not included. Please use your device's original cable.
Q3.  Anker external batteries' efficiency.
ALL external batteries lose power due to voltage conversion and circuit resistance.

Approximately 20% of Astro 2nd Generation external battery’s total capacity is consumed, including power lost from circuit heat and voltage conversion within the external battery (approximately 6%) and the charging cable and your device (approximately 14%). This efficiency rate is 15% higher than the industry average of 35%.

Older Astro batteries have lose approximately 30%.

According to industrial standards, all external batteries are labeled based on their raw cells capacity not efficiency. Like others, we are following this standard.
Q4.  How long will the battery lasts while not in use?
Generally, most of our external batteries' static power consumption is lower than 100uA, which will take between 3.5 and 20 years to drain the battery completely.

However, the chemicals within the li-ion battery will gradually become less active over prolonged periods without use. Most will die in 2 years of inactivity.

To extend your battery's life:
1. Charge and recharge it at least once every 3-4 months.
2. Do not over-charge or over-discharge it. It is best to keep it charged between 5%-95%.
Q5.  Can Anker external batteries be used for international travel?
Yes. Be sure the USB adapter you bring with is compatible with the voltage of the country you will be traveling to. An adapter's voltage input is usually printed on the adapter.
Q6.  Can external batteries be taken on board airplanes?
Yes, all Anker external batteries can legally and safely be taken on board airplanes. Here are the relevant requirements:

Quoted from Federal transportation security rules (Effective January 1, 2008):
Lithium ion batteries (a.k.a.: rechargeable lithium, lithium polymer, LIPO, secondary lithium).
-Passengers may carry consumer-sized lithium ion batteries [no more than 8 grams of equivalent lithium content or 100 watt hours (wh) per battery]. This size covers AA, AAA, 9-volt, cell phone, PDA, camera, camcorder, Gameboy, and standard laptop computer batteries.
-Passengers can also bring two (2) larger lithium ion batteries (more than 8 grams, up to 25 grams of equivalent lithium content per battery) in their carry-on. This size covers larger extended-life laptop batteries. Most consumer lithium ion batteries are below this size.

Anker's largest external battery is currently the Anker Pro 20000mAh (74 wh) which is lower than the above 100 wh limit.
Q7.  What can I do if I lose the provided accessories?
Please check to see if you have extras or contact us via email at support@ianker.com for help.
Q8.  Anker external batteries' compatibility
Anker external batteries are compatible with Android and Apple smartphones and 5V USB tablets including Google nexus 7 (Asus 15V tablets not supported. Apple connectors are not included, please use your devices original cable).
Q9.  Will the Astro 2nd gen unintentionally activate if I keep it in my bag?
Possibly. However, the Smart LED's power consumption is extremely low, so unintentionally activation (like bouncing around in your bag) will not noticeably detract from the battery's capacity.
Q10.  How can I identify the voltage specification for my device?
Please refer to your device's instruction manual, product labeling, or adapter to find this information.
Q11.  What if the Astro 2nd gen fails to charge my devices?
a. Check that the connection between the Astro 2nd gen and the electronic device is secure.
b. Check that the Astro 2 2nd gen still holds a charge, and recharge it when the remaining power is low.
c. Check that the Astro 2 2nd gen's voltage is compatible with the electronic device's.
d. Make sure that the charging cable is working.
e. Please email us at support@ianker.com duiring your 18-month warranty period if the provided acessories or the external battery have problems.
Q12.  What if the Astro 2nd gen fails to recharge?
a. Check that the adapter is connected securely, or replace it if the current one is not functioning normally.
b. Check that the USB cable is connected securely, or replace it if the current one is not functioning normally.
c. Please email us at support@ianker.com duiring your 18-month warranty period if the provided acessories or the external battery have problems.
Q13.  Can it charge the Samsung Tab?
Yes. The smart port does support charging Samsung tablets.
Q14.  How long does it take to fully charge this Anker external battery?
It will take 5-6 hours using a 1A output charger.
Q15.  Do I need to press the power button when charging other devices?
No. There is no power button on this external battery, instead, please give it a quick shake to start your charge.
Q16.  Can it be charged and charge other devices at the same time?
No.

Power Meter stopped functioning
After a few days of use, I found it so great that I ordered a second one, for my wife. But after using this one less than a week, the Power Meter stopped functioning, be it after gentle or stronger shake. I've tried recharging it the whole night, but it didn't change anything. Is there any way I can get it to work again ? It's a big trouble, not being able to know how much power is left in this device. If at all…

Input Specs
While looking at the different colors I noticed something rather strange. On the yellow and green Ankers the input is listed at 5V/1A. While the black color lists the input at 5V/1.2A. SO which one is it?

The optimum charging input for each of the Astro 6000 colours is 5V/1.2A.

The Astros were recently upgraded so we're working on getting consistency across the board for charging levels.

Probably not if you discharge your Nexus to zero but as that isn't advised and you would probably charge it earlier. It would probably charge it to around 100% twice.

Why doesn't my Anker work anymore?
I received this Anker External Battery for Christmas (2013) and used it successfully for a few charges.  It no longer works.  I've tried charging it by using different USB ports on my computer and via an A/C adapter, but if I try to charge my phone, the battery power actually decreases.  This was advertised to be a much better product than this, and I'm not satisfied with it.

Won't Charge
I received this as a gift for Christmas 2013.  It was purchased through Amazon and was new when I received it.  As of about 2 months ago, I noticed that it did not have a charge.  I figured since I had not used it for a couple weeks that maybe from being in my bag, that it lost its charge with all the movement since the light turns on when you move it.  Come to find out, it will no longer charge.  It was half a year old and no longer works.  I really liked it while it worked, but I am beginning to see that this is a common problem.  I guess I will try and return it, but that seems to be a pain since I asked for one of these so that I could use it, not spend several weeks returning it and waiting to get a replacement.

Too sensitive motion sensor
I recently purchased a 2nd Gen Astro 6000 mAh. I just received it in the mail today. However, the motion sensor is really sensitive and I'm worried about the device being activated too often. I just set it on the counter and it's lighting up when I walk across the room. Is that supposed to happen? I'm planning on having it in my bag when I'm out of the country next week and I'm concerned the battery will drain from lighting up non stop. Thanks for your time!

The Astro's shake-to-wake mechanism can be a touch sensitive from time to time.

Don't worry about it draining the battery though, it would take over 100,000 shakes to drain even 1% of the battery's charge level.

If you need a cable right away, several electronic stores carry those cables, or if you don't mind waiting a while...amazon usually has a lot of those cables at a lesser price.

Do you need a new Micro USB to USB cable or a wall charger?

We don't sell the Micro USB cables but they're available from all sorts of shops and electronics retailers.
