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.

To extend your battery's life, please discharge and recharge it at least once every 4 months.

Yes, all Anker external batteries including the 2nd Gen Astro Pro 20000mAh external battery can legally and safely be taken on board airplanes. Here are the relevant requirements:

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 Pro2 20000mAh (74 wh) which is lower than the above 100 wh limit.
Q15.  What should I do if the 2nd Gen Astro Pro2 20000mAh external battery can not be charged?

Solar charging with 12V-26W panel
Can I charge this device with a 12V - 26W solar panel?At present I use my solar panel to power a car-style 2.1A USB charger which in turn charges a 14KMah battery. However if the voltage changes (e.g. the sun is behind the clouds for a while) I have to re-insert the USB cable on the battery before charging resumes.Will this device trickle charge (take in any power it can get) or does it strictly require a constant 12V - 2A input?I'm sure the connector will fit and my solar panel is powerful enough.Best wishes - See more at: http://www.ianker.com/product/79AN7905-BA#sthash.n2Y0cNYS.dpuf

Charging problem
I recently bought an Anker 2nd Gen Astro Pro2 20000mAh Quad-Port External Battery with PowerIQ™ Technology, off Amazon and there seems to be a problem with it charging. I left it in a drawer for 5 days (after charging my phone) and it had about 75% charge left in it. I have just tried to charge my phone again, only to notice that my Anker battery is showing 00%, even when i tried to recharge it. I left it plugged into the mains for 5 hours and it is still showing 00%. The battery indicator bar is also empty. The voltage indicator is also showing 0v.Please could someone let me know if i need to contact the Amazon seller for a replacement / refund, or if there is a way to fix this issue.Thanks

See if you can find a 1st gen Astro Pro2 20000mAh, that device will. It was made for powering laptops and came with a variety of adapters for the power cable. They are getting difficult to find, but some are out there.

The ports are for charging USB devices, so you could charge an iPhone or an iPad, but not a MacBook laptop, as this would require a wall charging cord.

Maximum output from a single usb port?
I have a device that requires 5v/3amp output. Can a single usb output on this battery support this current draw?

USB output: 4.5A (max)PowerIQ works well, so I'd assume it can do 3A.Worse is it would charge a little slower with at minimum the 2.1A that the ports support giving to Apple devices

Justin is right. It shouldn't be a problem for this baby! Might just charge a little slower than expected.
