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.

DC output connection - 4.3mm??

Below, it says the DC output connection is 4.3 x 1.65mm. Is this definately correct? I can't find any connectors of this size. I'm aware the battery comes with it's own cable, but I need to make a custom lead for my camera. Many thanks.

That is the size of the (female) DC output port.

The cable that is supplied has a 4.3*1.65mm to 5.5*2.5mm male outputs.

This particular battery does not come supplied with adapters for the DC output cable.

However, you'll certainly be able to find adapters that accept the 5.5*2.5mm output.

Battery after fully charged.
I was wondering how long does the display and the backlight of the battery stay on after it's fully charged and leaving the battery plugged in. It says on the manual that the display will remain on after fully charged but doesn't says anything about how long the backlight will stay on and if eventually the display will turn off after certain time after it's done charging. Thanks.

charge from the car?

Hi,

I'm looking to be able to charge my 2nd Gen Astro Pro2 from the car. Do you carry, or can you recommend a cable that will do that sufficiently from the cigarette lighter?

Thanks,

The Astro Pro2 line of batteries cannot be charged from a car charger unless you are using a 12v/110v power inverter with the 110v/220v charger that came with the Astro Pro2.

Anker recommends only using the supplied AC adapter

We do not manufacture a charger for this.

If you have a charger that has a 5.5*2.1mm 12V/2A output then it'll work just fine with the Astro though.

Will Anker 14W charger charge AstroPro2

I recently purchased the pair in hopes i could use the Anker 14W Solar Panel Foldable Dual-port Solar Charger (Output 5V / 2A)

to power my Anker 2nd Gen Astro Pro2 20000mAh Quad-Port External Battery ????

Is this doable? What cord to use from usb?

Are there complications/warnings i should know of?

Can it damge the battery?

Sorry to say that this will not work. The max output of the solar panel is 5V/2A but the minimum input of the Astro Pro2 is 12V/2A.

We do have batteries with a higher capacity (the Astro E6 and E7) which will work just fine with the solar panel though!

The Astro Pro2 line is the only set of batteries that these chargers will not work on. Astro Pro2s require a 110/220v charger. But look at any other battery and you are good to go.
