Anker 2nd Gen. Astro 6000mAh Portable External Battery

Anker 2nd Gen. Astro 6000mAh Portable External Battery

Charger- 40W 5-port desktop charger

Product Description

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

- 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.

Customer FAQ

Q1.  Can I use USB cables other than those provided with my Anker external battery?
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 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 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 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?

samsung galaxy S4

I am looking for an external charger for my son to take on a trip. Which is the best for a Samsung galaxy S4?

How big of a battery do you want to carry? I love the Astro Pro 2, it holds a LOT of charge, probably almost 2 weeks worth for your phone, but it is quite larger than the other offerings. If you want smaller the Astro 6k, 12k offerings are much smaller and quGte a couple!ite nice. But nothing beats having a full phone charge in the size of a lipstick case in the Mini 3000.

Did you fully charge this battery before using?

This can charge an ipad mini about 150%

Yes I did fully charge the battery. I also noticed that the battery did drain very fast. I know there is an difference in the battery capacity of the iPad mini and iPad mini 2, but you say that the battery can charge the second gen iPad mini for 150% ?

IT Owl is absolutely correct. Just like breaking glass, only not glass. Or breaking. But it is the sound vibrations that are causing it to light, whether it is the case, platform or switch that is being affected.

Acoustics of the high note are on the same frequency level as the surface your battery is on or the plastic molding of the battery exterior causing micro-vibrations on the surface thus triggering the activation of the Light Emitting Diode.

I just purchased an Anker Astro 6000mah external battery and I was wondering if anyone out there had any knowledge on how many times the battery would charge an iPhone. The Anker site says 3+ but I was wondering if anyone was getting slightly more than that?
Replies(6) Collapse Report as spam Mar 7, 2014 at 11:46 AM
Nope. That sounds about right. You're not going to squeeze 4 full charges out of it. Of course that also depends on how much you let the iphone battery go down before connecting the charger, but you can count on 3+
Reply Report as spam Mar 7, 2014 at 11:57 AM
I get 3+ charges on mine, tested with battery within 8-14% left.

Anker does a hefty amount of testing on their products. If they say something, you can usually stand by it.

No, Anker is normally accurate on things like that.
Reply Report as spam Mar 7, 2014 at 5:03 PM
Just curious, under what conditions would it be necessary to get more charges than that without simply plugging in the charger to top it off? I'm sure there are times that would happen, in my case I consider my charger as a lifeline so it's always fully charged.

3 charges on an iphone should last you at least 3 days.

Plenty of time for a weekend excursion then you can charge it again

Can I use my iphone 4 while it is being charged? When I tried doing it, the charger wasn't charging the phone
Replies(3) Collapse Report as spam Mar 4, 2014 at 4:13 PM
Yes. But whether or not it indicates if it is charging shouldn't be a problem. When my phone battery is low and I attach one of my Mini 3000s, I use the phone with no problems while attached to the battery.
Reply Report as spam Mar 4, 2014 at 6:26 PM
U can use the phone while charging. But if the drain from the phone battery is more than the rate of charge it won't show as charging the battery. Use galaxy charging current app on ur mobile and u will know drain versus charge current.

You can, but that isn't good for the battery.

It would work if the input amperage is correct.

I don't see why anyone would try doing that though as that's just inefficient.

You'll lose battery power transfer and storage efficiency both ways. You'll lose some on transfer from one battery and lose more on storage in the other.

I don't see why you would want to push power between 2 batteries when you can just use the other battery that has power to charge your devices instead of using a battery to charge another battery to then use to charge your devices

Interesting question. I see it as trying to fill one balloon from another balloon. It's possible but all you're doing is depleting the air from the first balloon to fill the second one.
Reply Report as spam Feb 26, 2014 at 1:19 AM
But yes, you can do this. I do it when I need a faster charge in my smaller batteries than the wall charger gives.

Anker 2nd Gen. Astro 6000mAh
My Anker 2nd Gen. Astro 6000mAh Portable External Battery dies quick when I use it to charge my tablet, and also when i use it for my phone (2010mAh), is it that the tablet and phone is drawing a lot of power from the device, or is the device itself faulty, because if it's 6000 mAh, it should last for a while, right?
Replies(2) Collapse Report as spam Feb 20, 2014 at 9:18 AM

6000 mAh can charge your tablet and phone once.
It isn't dying quickly, you're transferring the power from the battery pack to the tablet and the phone and if the phone and tablet's capacity is high, then you just subtract whatever the sum is from 6000

So if the total capacity of your tablet + phone is 4000 mAh, add a little for transfer efficiency loss = 4300 mAh,

Subtract that from 6000mAh, you get 1700mAh left which is enough for one more phone charge
Reply Report as spam Feb 20, 2014 at 2:22 PM
If you are using the devices while it is charging, then it would be dying fast. It should charge your phone and tablet once.
