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

78APIPADMNI2-02USA

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

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?

The 3 USB ports share an output of 4.5A, the Power IQ technology means that they can predict your device's required power level and supply it accordingly. It won't be enough to power a laptop though, the max output if only 5V and laptops often need much higher than that.

The DC output port on the other hand (max 12V/1.5A) may be powerful enough.

Overload and short circuit protection
Overload and short circuit protection are very important when buying a item like this, for me it could make the difference between buying or not. Why are they not on the specifications of the product if it does have them? Do you have adapters for the power bank charger?Does it charge at 110v or 220v?

Yes, it does have short circuit and overload protection. We don't mention it on our listings because we have to cram as much information as possible in there and people asking questions regarding these protection circuits is actually still somewhat rare.

We don't actually have dedicated chargers for each of our external batteries but do sell many wall chargers and car chargers that work very well.

Our external batteries will charge at both of those voltages.

Charge device while plugged into wall?
Great looking product! If my laptop is dead AND the Anker battery pack is dead (but is plugged into the wall), can the anker battery still pass appropriate current to the laptop, or, does the Anker battery need to be charged from the wall first, before it can pass the necessary current to the laptop?seems like a redundant question I know, but i plan on purchasing this for a very soecific situation and I need the answer to this question. Thanks alot!

The 2nd Gen Pro is capable of pass-through charging but it is very bad for battery life and could severely shorten the lifespan.

You'll need to confirm the power input of your laptop as well, you can do this by checking its original power supply. The 2nd Gen Pro2 outputs 12V/1.5A, if this is higher than your laptop then it should work but if you're using pass through charging then the Pro2 will only charge very slowly if at all.

Is this external battery capable of charging a surface pro 3?

The max output of the 2nd Gen Pro2 is 12V/1.5A, you'll need to confirm that your Surface's native charger put out less than this. If it does then you'll be absolutely fine.

If not then our 1st Gen Pro2 is actually a little more powerful (19V/3A) and might work.

Solar Panel Charging?
Hi,I purchased this external battery and absolutely love it! I'd really like to be able to charge this via a solar panel, but it doesn't look like you carry a panel that is compatible. Do you have a recommendation on a solar panel to use? Does this battery absolutely need a full 2A at 12v to charge, or will it still charge (although just not as fast) at something like 1.3a or 1.5a?Thanks!

Glad to hear you're enjoying it!

The 2nd Gen Astro Pro may charge from a charger with lower output but we cannot guarantee it. If you have a solar panel that can output 12V/2A then it'll work no problem.

Sorry for the lack of information!

Yes, it does have that protection and the USB ports output 5V. And you should be able to select what output voltage you want from the DC output port.

Can this charge an Acer Chromebook C720?
I'm looking to purchase one of the new i3 Chromebook C720's. The battery on those is 3-Cell Li-Polymer Battery (3950 mAh) but I'm not sure what kind of power it takes. I was hoping to use this to provide some extra life to my Chromebook, among other things. Can this do it?

The max output of the 2nd Gen Pro2 is 12V/1.5A. You'll have to confirm that the Chromebook's requirements are lower than this, if they are then it'll work no problem.

The max output of the 2nd Gen Pro2 is 12V/1.5A. This probably won't be enough to charge your laptop but you can confirm the figures on your MacBook's original charger and if they're lower than that then you'll be good to go.

Unfortunately we don't manufacture a charger that is capable of powering the Astro Pro2 but if you can get a 12V/2A DC charger then it should charge up fine.
