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.

  • Bought this in a hurry so I could use it on a camping trip. I also wanted it for emergencies when power goes out and I need to charge a cell phone. It's performed extremely well. I can go an entire week using my phone based solely on the external battery.The only downside was that it didn't come with a wall charger. It only had a USB cable and at the time, I didn't have a method for using that for charging. So, I wasn't able to get a full charge before my camping trip. Eventually I found that one (and only one) of my phone chargers was able to deliver the full charge. IF you have to buy a charger, either go with the manufacturer's one or pay close attention to the characteristics of whatever you do decide to purchase.I definitely recommend this product

Customer FAQ

Q1.  Can I use a different USB cable rather than the cable that comes with the 2nd Gen Astro3 12000mAh external battery?
Yes, you can use other cables. However, to ensure compatibility and best performance, we strongly recommend using your device’s original cable, a third-party certified cable (such as MFI) or the included cable.
Q2.  What kind of wall charger should I use to charge the 2nd Gen Astro3 12000mAh external battery?
The battery can be recharged from any PC or laptop USB port or any USB AC adapter. A USB AC adapter with 2A or more output current will maximize charging speed. Lower currents will prolong charge time.
Q3.  What devices are compatible with the 2nd Gen Astro3 12000mAh external battery?
The battery is compatible with Android, Apple and almost all other devices charged via USB. It has a maximum output of 4.0A shared between the ports with each port able to deliver the full 4.0A.
Q4.  How long will the 2nd Gen Astro 3 12000mAh external battery take to be fully charged?
It takes alomost 9-10 hours to fully charge the battery with a 5V/2A wall charger.
Q5.  Does the 2nd Gen Astro3 12000mAh external battery work with the new iPhone 6 and iPhone 6 Plus?
Yes, but the Apple cable is not included. Please use your device's original cable.
Q6.  Will the supplied Micro USB v2.0 cable be compatible with Micro USB v3.0 devices, such as Samsung Galaxy S5/Note2/Note3?
Yes, take a close look at the port and you will see the port is divided, insert the none Micro-USB 3.0 plug to the appropriate side and it will work fine.
Q7.  What's the output efficiency of the 2nd Gen Astro3 12000mAh external battery?
The efficiency of this battery is around 70%-80%. The internal circuit board is 92% efficient, accounting for power lost through circuit heat and voltage conversion, which is up to 5% above the industry average. Energy is also lost within the charging cable and the device being charged (approximately 15-20%). Additionally, the efficiency can be affected by the cable length and the age of the device being charged.
Q8.  Can the 2nd Gen Astro3 12000mAh external battery charge other devices while it is being charged?
No.
Q9.  My device charges at 1 Amp, will the 2nd Gen Astro3 12000mAh external battery’s 4 Amp output harm it?
No, the external battery will only supply the maximum charge current allowed by your device.
Q10.  Can the 2nd Gen Astro3 12000mAh external battery charge multiple devices simultaneously?
Yes, it can charge three devices simultaneously. But please note that when using 3 output ports simultaneously, the total output current will not exceed 4A.
Q11.  What do the LEDs indicate when the 2nd Gen Astro3 12000mAh external battery is charging itself or other devices?
When the battery is charging your devices, the smart LED indicator will respire; displaying its remaining power. It will shut off automatically once your device has completed charging or ceases to draw a current.
When the battery is being charged, the smart LED indicator will light up. The constantly lit portion of the LED circle shows the current level of charge while the cascading LEDs display the portion still charging. The LED display will shut off once battery is fully charged.
Q12.  Will the the 2nd Gen Astro3 12000mAh external battery lose power when it turns on unexpectedly in a back pack or pocket?
Although it may activate occasionally when in your bag or pocket , the power usage of the LED indicator is negligible. It would take over 100,000 activations to drain even 1% of the battery's capacity.
Q13.  How long will the charge in a 2nd Gen Astro3 12000mAh external battery last without being used?
Generally, the 2nd Gen Astro3 12000mAh external battery's static power consumption is lower than 100uA, which will take between 3.5 and 20 years to drain 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, please discharge and recharge it at least once every 4 months.
Q14.  Can the 2nd Gen Astro3 12000mAh external battery be used for international travel?
Yes. Please be sure that the USB AC adapter is compatible with the voltage of the country you're travelling to. The input voltage of an adapter is usually labeled on the adapter.
Q15.  Can the 2nd Gen Astro3 12000mAh external battery be taken on board airplanes?
Yes, all Anker external batteries including the 2nd Gen Astro3 12000mAh external battery 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 Pro2 20000mAh (74 wh) which is lower than the above 100 wh limit.
Q16.  What should I do if the 2nd Gen Astro3 12000mAh external battery can not be charged?
Please try a different AC adapter and Micro USB cable to see if that helps. Email us at support@ianker.com during your 18-month warranty period if this doesn't fix the issue.
Q17.  What should I do if the 2nd Gen Astro3 12000mAh external battery can not charge other devices?
Please try a different charging cable between the Astro and your device. Email us at support@ianker.com during your 18-month warranty period if this doesn't fix the issue.

Yes, unfortunately that is right.

The LG G2 has unusual charging technology so it isn't compatible with a huge number of 3rd party external batteries and chargers.

How are you charging it?30% of 12000mAh is around 3600mAh which if you are charging from a PC USB port at 0.5A per hour is gonna take 7 hours ish, and off a 1A plug adapter is still 3.6 hours so this doesn't sound too slow.  It's just how long it takes to charge such a large battery. They do recommend using a 1.5A adapter as minimum.perhaps consider getting the Anker 40w 5-port charger with powerIQ which will charge at 2.1A

To charge a 12000mAh powerbank can take a long time, firstly the charger you are using can impact on charging time if the charger only has a low output, also not all cables are equal, some lose some of the power over the length, and is refered to as lossy.

Please make sure the charger you're using can charge at 5V/2A.

If it is lower than this then it may charge slowly or not at all.

Ability to charge unrecognized items
Hello,My last post seems to have been deleted?  I was wondering if anyone would be able to help me.  Will the Anker Gen2 Astro3 charge items that are "not recognized" by the IQ system?  I am thinking along the lines of a GPS or maybe even an iPhone 6?Thanks

We did respond to this question, not sure what happened!

Yep, it'll charge basically anything which takes charge via USB. We fully expect the iPhone 6 to be compatible.

Dear SirsI am considering either Anker 2nd Generation Astro E series or the 2nd Generation Astro 3.series but find my self going backwards and forwards between the two, unable to decide. Apart from dimensions,weight and mAh is there any technological or other difference between the two catagories, knowledge of which may help me decide.. I am in the UK in case that has relevance.ReagrdsPaul

Besides the size, weight, and the LED on the Astro E series. There is no functional difference otherwise with power IQ

ANKER Team


The power output is the same over both products, they both have Power IQ and will charge your devices very quickly.

The differences emerge with the 2nd Gen Astro3, it has the three USB ports and a very high potential amperage output from each port. The 2nd Gen E range have a 3A max output where as the Astro3 has a potential 4.5A to play with.

Also, it's worth considering how much weight you're willing to accept for your capacity requirements!
