  • Wonderful Battery replaced my Car Charger
  • After using car chargers (which seem to overheat my iPhone), I now use this Anker 2nd Gen Astro2 9600Ah 2-Port 3A portable battery. It has worked flawlessly. The circular charging light coming on when the battery is moved has had no effect on my use.

  • best charger
  • I love this charger. Not only does charge my device quickly I did have to recharge it for almost two weeks of using it. Ive used other charger and found them slow. I love the charge indicator. Only negate the model I picked is a little heavier than I would have liked. This is the only reason I didn't give it 5 stars.

Q6.  What's the output efficiency of the 2nd Gen Astro2 9600mAh 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.
Q7.  Can the 2nd Gen Astro2 9600mAh external battery charge other devices while it is being charged?
No.
Q8.  My device charges at 1 Amp, will the 2nd Gen Astro2 9600mAh external battery’s 3 Amp output harm it?
No, the external battery will only supply the maximum charge current allowed by your device.
Q9.  Can the 2nd Gen Astro2 9600mAh external battery charge two devices simultaneously?
Yes, it can charge two devices simultaneously. But please note that when using 2 output ports simultaneously, the total output current will not exceed 3.0A.

Q11.  How long will the charge in a 2nd Gen Astro2 9600mAh external battery last without being used?
Generally, the 2nd Gen Astro2 9600mAh external battery's 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, please discharge and recharge it at least once every 4 months.
Q12.  Will the the 2nd Gen Astro2 9600mAh 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.  Can the 2nd Gen Astro2 9600mAh 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.
Q14.  Can the 2nd Gen Astro2 9600mAh external battery be taken on board airplanes?
Yes, all external batteries with a capacity lower than 27027mAh (100 Watt Hours) can legally and safely be taken on board airplanes. To calculate a battery's capacity in Watt Hours: (Battery Capacity(mAh)*3.7)/1000.

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.
Q15.  What should I do if the 2nd Gen Astro2 9600mAh 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.
Q16.  What should I do if the 2nd Gen Astro2 9600mAh external battery can not charge other devices?

flashing LED light?

I recently purchased the Anker® 2nd Gen Astro2 9600mAh. When I plug in my iPhone 5c to charge, the indicator light flashes continuously, even with different cords.  According to my phone's battery indicator it appears to be charging but the LED light flashes, rather than pulses. This was not the case on my first couple of charges. Is this normal and safe for both devices?

Is is compatible with galaxy note 4 ?

Hi,

I am always surprised about the anker's spectacular products. I have a galaxy note 4 with 3220 mah battery. I don't know what is the best option for a portable charger to use with it

- ankro 2nd gen astro 9600 mAh OR

-Anker 2nd Gen Astro E3 10000mAh OR

-Anker 2nd Gen Astro E5 16000mAh External Battery with Lightning Cable.

I need something to use it usually when i travel. Also i need to know bout the adapter because the electrics in some countries outside the U.S is 220 Volts

instead of 110 Volts. 
Thanks

Hi, 

First, YES, it is compatible with your Galaxy Note 4.

All the options are good, so choose the best for you. Remember that the lightning cable is just for Apple devices, so you can buy it without it.

Finally, do not worry about 110/220V, you could charge it on both.

If you want to be 100% sure, contact support@ianker.com.

You are welcome. ;)

All our batteries will be fine charging at almost any voltage so you needn't worry about that.

All those chargers will charge your Note 4 as fast as possible without Quick Charge so the decision really is yours about how much size and weight is convenient weighed up against capacity.

It may work with the G2 but we cannot guarantee it so we note it as incompatible. It would never cause damage to another device, we just can't confirm it will definitely charge.

And, every external battery can have those problem with the LG g2 phones or just the ANKER have something different? Sorry if I have a lot of question, I'm deciding if buy anyway or not, Thanks a lot for the support.

It allow Anker to focus on manufacturing and not on a sales website, website security and distribution. Those are big headaches to do yourself when there is someone else can take care of them for you and they have the infrastructure in place to do it.

Anker 2nd Gen Astro2 9600mAh

Hi,

I am interest in the Anker 2nd Gen Astro2 9600mAh External Battery as it is light, small, provides 2 usb ports and has excellent reputation.

I am planning on charging an external battery using a bicycle hub dynamo, that will have its output regulated by a Bosch and Muller USB Werk. This devide only provides up to 5V, 1A via USB connection.

Is 1A enough to charge an Anker 2nd Gen Astro2 9600mAh External Battery? If so, how will a lower current affect its charging?

Thanks

Alex

yes it is. however you will  run into a problem that the battery will not charge a device while it is being charged itself. Anker has started to limit pass-through charging in its firmware. so if you want to be able to charge a phone or light while your dynamo is charging the Astro2, that will not work.

Charging iPhone 6 plus

Hi, i was very happy finally i can recieve my Anker product order from my sister that live in the US.

I got high expectation on this product, especially someone else in this forum already ask how many many time this model charge iPhone 6 plus

the Anker team answer : around 2.3 times

but in my experience i left my iPhone 6 plus to 16% battery left and start charging with Fully Charged Astro 2 and the indicator indicates it is less than 50% of the Astro capacity.

so means : My Astro even can not charge 2 times of the iPhone 6 plus 

what do you think about this guys please let me know, Thanks

Hello Lasika,

Quick question for you.  Do you happem to have any "draining" application running in the background as you are charging your phone.  ie gps etc...   I realized that these type of applications hard hard on the backup battery as well.  Don't know if anybody ellse has encountered the same thing.

Reply Report as spam Feb 14, 2015 at 4:36 PM
ANKER Team
Charging your device is never 100% efficient.

The Astro's 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%).

To calculate roughly how many times the battery should charge your device you can use this formula:

(Capacity of the Astro * 0.7) / Capacity of your device = Number of possible charges

If you're finding your Astro has lower efficiency than this then give our customer service team a shout at support@ianker.com.
