Anker 2nd Gen Astro Pro 15000mAh Triple-Port External Battery with PowerIQ™ Technology

Anker 2nd Gen Astro Pro 15000mAh Triple-Port External Battery with PowerIQ™ Technology


Product Description

Tablet & phone compatibility? Universal max-speed charging? Power-packed & portable? The reinvented Astro Pro 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.

Up your power.

15000mAh of power keep you and your gear going, and going - and going. Add 700% more battery life to an iPhone, 400% to your large-capacity phone (like a Galaxy S4), or 100-200% 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

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 for help.
Q8.  Can it be charged and charge other devices at the same time?
Yes, this battery can simultaneously charge and discharge. However, constant pass-through charging may affect the battery’s lifespan. Note: When the battery’s power level is below 30%, the multi-voltage port will not charge another device while the battery is being charged. The USB charging ports are not affected by this limitation.

Straight 12v power supply
I see that teh info says this external battery will talk intelligently to a device being charged such as a phone but I simply want to use it as a 12v supply power to some electronic instruments that do not have their own battery and are therefore not being charged. Can it be used to do that (power rather than charge) or will it be confused by not being able to identify the item being connected?

As long as there is a consistent power draw over 0.05A from the device that you're trying to power then it'll work no problem at all.

It is compatible with the LG G2. I don't know what the net weight would be for the package. I would assume about a pound
Reply Report as spam Aug 8, 2014 at 6:54 PM

Unfortunately it isn't compatible wit the LG G2, the G2 has unusual charging technology and isn't compatible with a large number of chargers or external batteries.

Net weight is 13.6 ounces.

Can you charge via micro USB?
I've had the 15000mAh Astro E5 for a while now, and one of the things that's great is as well as charging from a wall plug, I can also charge from the fast charge port on my laptop or by using the USB charge hub to save on power outlets needed; is this possible with this version?

The 2nd Gen Astro Pros all come with their own AC charger as they're just too high capacity to be able to receive a charge from 5V chargers.

USB port max voltage
My device requires a 9VDC/3000mA and doesn't charge via USB, but rather the other type. Does the Anker product's USB port provide 9VDC, assuming I can find a USB to barrel(??) connector? I'm assuming the Anker's 9VDC/2A won't be powerful enough for my device
Replies(2) Collapse Report as spam Jul 16, 2014 at 10:47 AM

The 2nd Gen Pro will output the 9V DC power but it won't do the 3A.

Take a look at the 1st Gen Pro2 (max output 19V/3A), that'll be able to charge your device. You may need an adapter for the DC output cable though.

Since the device I want to charge is 9VDV, will the 12V min of the 1st Gen Pro2 damage my device?

En réponse à votre questions, nous vous informons que seul nos Batteries Externes Astro Pro 2nd Génération qui sont munie d'un port multi-voltage 9V / 12V sont compatible avec les tablettes Asus en raison du voltage requis pour alimenter ce genre d'appareils (plus de 12V).

Yep, the 2nd Gen Pro is able to output 12V/1.5A so it'll work fine!

Anker with Blackmagic Pocket
Is it possible to power up Blackmagic Pocket Cinema Camera ( with Anker 2nd Gen Astro Pro using such ( or similar cable? Theoretically it should work since Anker 2nd Gen Astro Pro provides 12V DC output, but I'm not a tech guy, so just want to be sure. Thanks.P.S. There are hordes of filmmakers out there looking for convinient power solution for the BMPCC.

If the Pocket Cinema's power requirements are lower than the 12V/1.5A output of the Pro's DC output then it will have the necessary power to charge it.

The DC output port on the Astro needs a male plug of 4.3*1.65mm so your adapter should have that at one end and then the Pocket Cinema's size output on the other.

Please do get in touch with our customer service guys a and let them know if you have any further questions.

You should be able to get a replacement cable at any small electronics shop in the UK.
Reply Report as spam Jun 14, 2014 at 11:43 AM

Unfortunately we don't have a warehouse in the UK that is able to provide replacements for the AC chargers.

You should be able to find a replacement charger easily enough, the input size is 5.5*2.1mm and it needs to output at least 12V/2A.

Battery protection from draw to empty.
Since the batteries inside of the Anker Astro Pro is on Lithium tecnology, is there a protection for over discharge when using 12v port?
Replies(3) Collapse Report as spam Jun 3, 2014 at 8:27 AM
Hi, can I just ask when you say 'over discharge' do you mean 'over charge' as in cut off protection from the battery (hitting 100% full) over heating?going off my 2nd gen Astro 3 then yes there is, the battery turns off when it hits full, the LEDs do not stay lit and it will only be drawing a trickle charge if anything at all
Reply Report as spam Jun 3, 2014 at 10:42 PM
No, I mean over discharge. I used it on an DeWalt Heated Jacket, and I forgot to turn it off and leave it for a day. When I take the Astro Pro to charge I saw the lcd display showing 1% but it still light up the screen. So knowing that the batteries on lithium are dangerous if over charge AND over discharge, I asked if there a protection to the mentioned over discharge.I think is pretty weird that with only 1% of charge, the battery can turn it on the 12v output. Is it not like when you charge the battery and automatically shut off when 100% charged? Stemcgoo, I think that there is no trickle charge on lithium battery as you mentioned because the tecnology is different from a car battery. As I know is dangerous to trickle charge a lithium battery.

Absolutely there is. Please use it to charge any device with any capacity with total peace of mind.
