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

78APIPADMNI2-02USA

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.

• Please use your device’s original cable or a third-party certified one (such as MFi).
• Compatible with all Apple and Android smartphones, tablets (including the Nexus 7) and other USB-charged devices. The iPod nano, iPod Classic, HP TouchPad, LG G2, Asus tablets and some GPS and Bluetooth devices are not supported.

  • Great charger with incredible outputVerified PurchaseThis review is from: Anker® 2nd Gen Astro3 12000mAh (4A Output) Portable Charger Triple USB External Battery Pack with PowerIQ™ Technology for iPho
  • This is an amazing charger if you got several devices to charge and/or are out without outlets for a lot of time, it is about the size of an external hard drive.The thing that really sets this charger apart (compared to, for example, a mophie powerstation i own) is the charging speed, the Astro3 will charge everything at full speed without overheating batteries.

Customer FAQ

Q1.  Can I use USB cables other 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.

Yes, that is the recommended port. It should take around 7 hours to be fully charged using that port.

Fully Discharge
is it advisable to fully discharge lithium batteries at least once after every how many number of months ?

I've always found that it's not advisable to fully discharge LI batteries. Nor is it advisable to fully charge them. Go to 5% and 95%.

just on a side note, what fries a battery are fast discharges so for example, you are playing a super demanding video game, that drains the battery quickly, keep it conected to the charger...

We'd recommend charging it and discharging it at least once every couple of months.

If you bought it that long ago then it may not.

If you send our customer service guys a mail at support@ianker.com with your order number then they'll be able to confirm definitively for you.

Thanks for your questions.

1) It should have some charge but we can't guarantee exactly how much!
2) It may have lost some charge but as we won't know how much was there in the first place we can't say how much!
3) It may have caused some issues, 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 2 months.
2. Do not over-charge or over-discharge it. It is best to keep it charged between 5%-95%.

Charging unsupported products
Hi There,Quick question,Will this battery pack still charge items that are not necessairly supported but still charge by USB?  I'm thinking of items like a GPS or possibly the iPhone 6?

Yes, it'll pretty much charge anything that takes a USB charge. We fully expect it to be compatible with the iPhone 6.

You can charge the 2nd Gen Astro3 from almost any charger as long as it'll output 5V/2A (this includes car chargers and different branded wall adapters).

All the USB ports on the 2nd Gen Astro 3 'll charge the S5 at the same speed.
