Anker 2nd Gen Astro Pro2 20000mAh Quad-Port External Battery

60W wall charger - product

Product Description

Tablet & phone compatibility? Universal max-speed charging? Power-packed & portable? The reinvented Astro Pro2 has it all.

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.

Uber powerful.

20000mAh of power keep you and your gear going, and going - and going. Add 1000% more battery life to an iPhone, 600% to your large-capacity phone (like a Galaxy S4), or 130-300% to your tablet (depending on its battery capacity) - all away from an outlet. What's more, the added energy efficiency gives you 10% more usable power than the previous generation and many standard alternatives.

Brilliant display.

Interacting with the all-new aluminum-cased beauty couldn't be easier. The LCD simplifies everything - displaying the remaining power (with precision down to the percent), output, input and voltage selection.

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.

Customer FAQ

When the battery is being charged, the LCD display will display the battery's capacity throughout the charging process and remain lit after fully charging.
Q11.  What voltage setting should I select to charge my phone or other USB-charged device?
All USB ports have an output of 5V so you don't need to select the voltage for charging USB devices. The voltage selector is for the DC output port.
Q12.  How long will the charge in the 2nd Gen Astro Pro2 20000mAh external battery last without being used?
Generally, the 2nd Gen Astro Pro2 20000mAh 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.

Compatable Solar Charger

Can you give advice as to which portable solar charger I could use to charge the Anker 2nd Gen Astro Pro2 20000mAh Quad-Port External Battery.

It only take 2A input, so any solar charger with a 2A output should suffice.

Thank you for coming to Anker with your query!

The 2nd Gen Astro Pro2 is a very high capacity external battery. You will want the solar charger with the highest possible output current, which would be the Anker 14W Portable Foldable Outdoor Solar Charger with PowerIQ™ Technology.

Please feel free to contact us again in the future with any questions or concerns at support@ianker.com!

If it's been less than 18 months since purchased, the warranty should cover it.

Cable to power MacBook Air?

What cable is recommended / supported for the MagSafe connector of a MacBook Air, using the barrel connector of the Anker 2nd Gen Astro Pro2? I bought the cable recommended below (http://www.amazon.com/dp/B00OL9QO6U/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=1LHMKH822FWEU&coliid=I2NG9MHQKRZH37#sthash.pkFIlOxP.dpuf) but the barrel only fits in the Anker Pro2 charing port.

Any help would be appreciated, even if someone can tell me that I'm doing something wrong and this cable will work.

Thanks,
- jason

External battery with 7.5V output?

I'm looking for a external battery to power my Sony a7II camera.  Do you offer a battery with a 7.5V output?

Thanks,

Difference with the Astro Pro2 First Gen

I have the first gen of this device and I got it to work with my Macbook Pro Retina using this cable http://www.amazon.com/dp/B00OL9QO6U/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=1LHMKH822FWEU&coliid=I2NG9MHQKRZH37 plugged directly into the output socket.

I am interested to get this newer version but I want to be able to properly use it.  I noticed that the sockets are of different sizes...What are the sizes of the sockets now?  If the output is different from the earlier version, what adapters do I need for me to get the above mentioned Macbook magsafe 2 connector to work with it?  

Lastly, can I plug this to a car charger?  if so, what kind of male plug should I use?

this has lower voltage than the Astro Pro 

you should be able to charge using the same connector

I don't know if this cable worked with the 1st Gen Anker Pro2, but it does not work with the 2nd Gen. The barrel connector only fits in the charing port and not the "output" port. 

Does anyone know of a cable that's compatible with the 2nd Gen and has the MacBook Pro MagSafe connector?

Hi there,

I have a new Macbook 12inch Retina. What battery charging solution would you recommend for the new USB c connector?

Kind regards

Any Wall Poower would work 

Recommend Power Port6 with 3Amp output 

and get a anker usb 2.0 to usb C

You have to keep in mind that your Macbook will charge slower when using a 5V charger. Otherwise, the PowerPort 6 will be great to charge your Macbook and other USB-charging devices.

Do any of your external batteries work with Dell XPS 2015 15 inch?   Which port is used to charge them?  Do you need a cord or is it included?

Sorry, we are not so sure whether we understood correctly. If you were just asking if the Astro Pro 2 will charge a device even when it normally should use ACDC or AA LR6 - that will work.

please tell us more about thequestion 

this will only work with the Ac or USB cable 

H6 works but not sure about the yamaha

Reply Report as spam Aug 8, 2015 at 10:08 PM
Alison Scott

The H6 describes one of its power options as USB bus, so I think you will find that will work. However, the PDX-11 is powered by 6AA batteries, so draws 9V and does not have a USB bus. So it's definitely not intended to work! You might be able to get more information from support@ianker.com . 

You might consider buying one or two USB AA battery chargers, which would definitely work with the power bank, and could be charging up a set of AA batteries while you were using the speaker with a different set.

Sorry, I think my previous answer was just plain wrong -- the Astro Pro 2 will supply 9V/2A DC. I don't know whether it will work with your PDX11.
