Anker 2nd Gen Astro3 12000mAh External Battery Charger with PowerIQ™ Technology

Anker 2nd Gen Astro3 12000mAh External Battery Charger with PowerIQ™ Technology

9901 Bluetooth speaker

Product Description

The all-new 2nd generation Anker® Astro3 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.

Packed with power.

We figure, the more power, the better. Packed with 12000mAh of juice, and featuring an energy efficiency rate 10% above previous generation Astros and many current standard alternatives, the new Astro3 charges the iPhone six times and large-capacity phones like the Galaxy S4 almost four times.

Double take.

Chic and minimalistic, the new Astro3 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 Astro3 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 25W 5-Port Wall Charger.
- 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.
- 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.

  • works fine, but the power juice ratings may be over rated, I am not sure, hope someone can measure it with instrument. also the recharge needs to notice, it must use high output USB plug to push the new juice in, you can't use anything like iphone charger to do the job, it won't work even overnight.

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.

Hi, I bought this device to use it in the library while Im out of charge for my devices. Although it takes at least 10 hours for this device to be charged , but it will give you a lot juice for your electronics devices. To be honest, so far, this is the the only device that can charge my note 10.1 among other power banks that I bought. If can charge my I pad 2 2.5 times from 5 percent to 100 . It has a nice LED that indicates the amount of charge that left. By shaking it , it will show you the amount of charge that remained in it. The body is made of sturdy plastic material and the white color one is so gorgous.It came with a nice pouch. I use the Pouch for my other stuff too.

If you use a charger that can output 5V/2A then it should charge in as little as 6 hours!

Max output current per port?
I see total output capacity over all ports is 4a but what is the maximum output current possible for a single port?  Specs on Amazon say that a single port will output up to 4a but this would be the first pack I've seen capable of such current.

That is correct, one port can output 4A.

all good things...
I've had 2 Anker Astro 3s (10000mAh) now: the first stopped charging after a couple of months and I was sent another by you (thanks)  and now that's stopped charging too. Same charging system/output as when it worked: cables, plug etc etc. Oh well, nothing lasts forever, and it was so good I'm ordering another (the 12000 I think). Anybody got any reasons why this happens though? I think I got 3 years out of it, so no complaints really; just would like to know.

The Astro3 is a very reliable device so its incredibly strange to see two defective with the same customer.

If the charger you're using is capable of outputting 5V/2A then it should be charging no problem.

We'll be more than happy to get you a refund for the original order or provide another replacement if you'd like to try again? Give our customer service guys a shout at support@ianker.com and let them know.

It does sound like it may be playing up. Could you change the charger and the cable first to see if that brings any joy?

2nd Gen Astro3 all Smart port capacity
Hi, I recently bought a 2nd gen Astro3 from Amazon. I understand that you can't get all 12000mAh because of resistance, heat loss, etc but mine (fully charged) has managed to charge just an iPad mini Retina fully (6471mAh) and 80% of an iPhone 5 (about 1200mAh). It amount to barely 7700mAh, is it normal?

First, according to iFixit the iPhone 5S has a battery capacity of 1560mAh. Second, assuming that you were charging both at the same time, and that they were both very close to dead, this does (mostly make sense). All apple devices I have dealt with ( I own both a Retina mini iPad as well as this battery) will not utilize the full amperage they are asking for below 10% or over 80%. Outside of these ranges Apple devices trickle charge (it says so in the manuals). Other devices trickle charge as well, but at different percentages of battery power. These are all Lithium Polymer devices. You got just over 8000 mAh of power out of your battery. This is a little low, I will admit, but it is within reason. When I change my iPad alone it uses about 80% of the battery, (2 or three lights remain). That would leave 2400 mAh for the iPhone, and you have to remember that the battery too has to stay conditioned so likely only will output about 11000 mAh of power (If Lithium ion battery's die completely they will not hold a change any longer).

Tl;dr iPad's use a lot of power, batteries trickle charge, and Lithium ion batteries cannot be completely discharged.Sorry about all the paraphysis, I know it drives some people crazy.

Thank you for the replay but I need to correct you, I have an iPhone 5 not 5S, it's battery is 1440mAh and my Anker charged it at 80%, so 1200mAh to be generous. The total amount of power recharged was 7700mAh. If what you are saying is correct that amounts to a 4300mAh not utilizable over a12000mAh battery... Wow, I didn't expect that, now I'm waiting for the Anker team to give a confirm. And no, I didn't charge them at the same time, first iPad then iPhone. Yes, they were fully discharged.

My iPhone 5 is not new, it's a year old, so the battery does not even hold 1440mAh anymore. That implies that even less mAh were extracted from the Astro3. The iPad mini is brand new.

I own one of these battery packs and unfortunatly it sounds as if yours has a problem, i can charge my LG G2 about 3 times from around 25%-30% to full. Mail them and i'm sure they'll be happy to help!

This is lower than we would expect from the Astro3. A reasonable estimate is that 70-80% of the power is transferable.

If you could do a couple of recharges and discharges and you're still having problems then give our customer service guys a shout at support@ianker.com and let them know. Remember, all our products have an 18 month warranty.

Using wall charger with Astro 3
I have the 2nd generation Astro 3 and when I plug it into the wall charger using the cord provided, the results are inconsistent.  Sometimes, it will charge completely, other times it will charge partial or not at all.  I get mixed results on the same outlet.  Thanks for your help!

The Astro3 is a fairly powerful battery and so it needs a fairly powerful input. Can you confirm that your charger is capable of outputting 5V/2A?

If it is and you're still having trouble then give our customer service guys a shout at support@ianker.com and let them know. They'll be more than happy to help you out.

Currently it doesn't support the Qualcomm Quick Charge technology.

In fact, unfortunately the Astro3 can be prone to compatibility issues with the G2. If you're interested in one of our external batteries but you're mainly looking to charge the G2 then the E4 or E5 might be a better choice.

Samsung Galaxy Note 10.1 2014
I've noticed that many, if not most, external batteries are not 100% compatible with the Samsung Galaxy Note 10.1 2014 edition.  Either the batteries won't charge the Note 10.1 at full amperage (and speed) or the batteries will not charge the tablet at all.Is the 2nd Gen Astro3 100% compatible with the Galaxy Note 10.1 2014?
