Anker 2nd Gen Astro Pro2 20000mAh Quad-Port External Battery with PowerIQ™ Technology

9901 Bluetooth speaker

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

- 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.
- Compatible with all Apple and Android smartphones, tablets and other USB-charged devices. The iPod nano, Asus tablets (not include the Nexus 7), the LG G2 and some GPS and Bluetooth devices are not supported.

Customer FAQ

Q1.  Can I use USB cables othan 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.

The Xperia has a battery life of 3,200mAh so if we take efficiency loss into account then you'll get almost dead on 5 charges.

Supposedly a lithium ion battery will last longest if you don't run it down to 0% nor charge it to 100%.

It won't matter if you run it down to 0% on occasion but we'd recommend trying to keep it between 5%-95% to give a maximum potential lifespan.

Thank you for both the responses, now i can recharge my battery without paranoia. I just wanted to make sure it was okay to charge my device when it was around 20 percent because I know some people who drain it while I leave some life in it. Once again thank you both !

Mr. Wayne Ross
Is the 2nd Gen Astro Pro2 20000mAh Quad-Port External Battery compatible with the 15" MacBook Pro w/Retina display and do you supply the MagSafe 2 adapter that plugs into it? Or do you have another external battery pack that is compatible.The label on the AC charger unit that came with my MacBook Pro w/Retina states: 20v === 4.25A max. They claimed about 8 hours use from the internal Lithium-Polymer 95 WH battery, but I'm lucky to get 3-4 hours with my configuration and use. Help!

The max output of the 2nd Gen Pro2 is 12V/1.5A so that will be very far underneath what the MacBook requires. It probably wouldn't work.

Our most powerful external battery (1st Gen Pro2) can output 19V/3A so it doesn't look like that would be enough either.

Mr Chris Brumwell
I'm looking for a portable 12v power source to power photographic equipment in the field. The equipment has no internal battery, can this device be used as a battery or does the on board electronics only allow it to be used as a charger?

You'll be able to use this to charge devices that don't have batteries but you'll need to ensure that there is a constant power draw to prevent the Pro2 from switching off.

If the power draw goes below 0.05A for more than 50 seconds then it'll power off and you'll need to press the button to begin charging again.

First time use
I just took it out of the box. So what should I do first? Should I charge it? Or should I just use it to charge my phone?

Feel free to do either!

If you're going to need to rely on it for something important then get it charged up to 100% but you can use it from its current percentage with no problem at all.

iPad air charge
Hi another questionipad air charge would be quicker through the DC output yes? (sorry not very good with electical knowledge) does it come with a suitable adapter and if not what adapter is needed?

The iPad Air will take a 5V input so you'll be much better charging from the USB ports.

Just use your iPad's original cable in the USB output ports on the Astro.

How did this model get a 74Wh?
To get watt-hour its ' Ah x V = Wh' Ah in this case is 20 (20,000/1000=20Ah) so 20Ah x 3.7v = 74Wh however I dont see 3.7v in the product specification i see 12v and 9v. Please could you kindly correct me as I will be purchasing this product soon!

We don't really use the 74Wh figure in our listings or on our website.

If you could get in touch with our customer service team at support@ianker.com and let them know exactly where you've seen these calculations then they'll be able to get some clarification for you.

I read on your FAQ under the question is the product allowed onboard airplane. You claim and i quote "Anker's largest external battery is currently the Anker Pro 20000mAh (74 wh) which is lower than the above 100wh limit" What exactley is there watt hour for this model and the astro e4's?

macbook charger?
hiwill the Anker 2nd Gen Astro Pro2 20000mAh charge a macbook? like the 1st gen does?

The max output of the 2nd Gen Pro2 is 12V/1.5A, you'll need to confirm the MacBook's power requirements from it's original charger (should be written somewhere on the charger itself) and if the number is lower than the output of the Pro2 then it should charge fine.

Remember, the max output of the 1st Gen is 19V/3A so that's a fair amount higher than the 2nd Gen.

Solar chargeable?
Hi!i just want to know if your Ankar Solar charger 14 Watt can charge the external battery, Pro 2
Replies(1) Collapse Report as spam Jul 15, 2014 at 3:34 AM

Unfortunately the Pro2 needs an input of 12V/2A and the solar charger just isn't capable of outputting this.

To provide a larger amount of charge the solar panel would need to be much bigger and it would be very difficult to keep it convenient to use.

The solar charger will charge some of our smaller capacity batteries though, like our 2nd Gen Astro range and our E3, E4 and E5.

Google Chrome Pixel
The Pixel appears to use a 12V charger. Your device came with a cable for DC Output. But, the connector on the end that is to plug into a 9V or 12V device does not fit my Pixel. Do you sell a cable that will work, or can you please refer me to a source? Thank you.

Unfortunately we're not sure exactly what you mean by Pixel. If you could give our customer service guys a shout at support@ianker.com and let them know exactly which device you're looking to charge then they'll be able to help you out.
