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.

Current when charging multiple iPhone 6s
Does the charger intelligently split the 4A of available output among the three ports?In other words:1. When charging two iPhone 6s, will each one get 2A?2. When charging three iPhone 6s, will each one get 1.33A?

Start charge process
i have some worry about the shake to view power left and shake to start charging. I hate my current external battery pack that I have to push a button every time I need to start charging. Even if I unplug device for a quick 2nd. Does this charger work the same way? What is the process to start charging? Shake then plug in device? Plug in device then shake? If I unplug device for a few seconds, next time I plug in will it start charging or I need to shake again? How intensely do you need to shake device, worried as well with the device being in my back pack if it will turn in continuously and run down my battery? If it turns on how long till it automatically turns off? I wish all your packs included the digital percent number like the pro pack u offer.

Safety features
How many and what kind of built-in safety features you have for the 2nd Gen Anker portable chargers. I never see you talking about safety features in your website. It is really important to protect the battery, the device and the user.

A little heat is to be expected but if you're noticing significant heat that is difficult to touch then stop using the battery and give our customer service guys a shout at support@ianker.com and they'll help you further.

We're developing the EU version of the 4 port charger right now!

The 2nd Gen Astro3 has a higher amperage output, an extra USB port but slightly less capacity.

Using GPS while charging
I want to use my phone's GPS to track long bike rides without the battery dying. Can I plug my phone into this and then just let the GPS run?

Yep! I have used my charger while hiking all day so that I can access maps or other information without the battery dying. You will need to supply your own phone charger cord, but otherwise it is just plug in and go.

Absolutely you can yes! Your phone will work as if it is on charge from a mains socket.
