Anker 2nd Gen Astro E3 10000mAh External Battery

60W wall charger - product

Product Description

The next generation Astro E3. Refined to power the mobile, connected life even better.

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.

Grab-n-go ready.

With the importance of staying connected ever increasing, eliminate low-battery fear with the grab-n-go Astro E3. Power your iPhone 4+ times, a large-capacity phone like the Galaxy S4 more than twice, or a tablet once (depending on your model).

Simple, reliable power.

Designed to be functional and efficient - nothing else. At 0.59in thin, the E3 comes ready to serve as an unobtrusive, lightweight solution to your daily power needs. And, increasing the new Astro E3's recharge rate from 1.5A to 2A, we've reduced the recharge time 25% to just 6 hours (with a 2A adapter).

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.

  • good cheap portable power
  • Works great so far, charged my iphone5s 6 times fully.Output USB ports were tough to put plugs in, after several uses they work ok now.Input USB works well, needs to be on 2a charging or it takes For-ev-er.The faceplate was slightly peeled off. Does not seat fully into space provided for it. This does not affect performance, or my review.I will update after 3 months to tell battery life.

You appear to be asking for a replacement internal part, not a micro USB cable of course. That would not be a user replaceable part. The good news is that if you puchased it from Amazon or another authorized Anker source you likely are still covered by the 18 month warranty. No additional proof of purchase is required, just drop an email to the warranty service team exlaining the situation to get their feedback. They can be reached at support@ianker.com

Most li-ion have a life cycle of, at most, 1500 cycles. They will also degrade down to 70% of their original capacity after 500 cycles.

How do I use it? (Astro E3)

Hi, I bought this a while ago but have hardly used it but would like to. When I turn it on (using main (round) button, all 4 lights go on. Does that mean it's fully charged? How is this possible if i haven't used it for over a year? How do I know if it's charging / charged, or how much power is left when I take it somewhere with me?

Thanks.

plug and charge 

its simple 

if the device starts to charge you will see LED turned on 

If you want to see the battery left press button

Yes, if the 4 lights are on, this means your external battery is fully charged. When being recharged, one LED will start blinking. If the battery is partially discharged, the equivalent amount of LEDs will switch off.

Charging Question

Hi -

I recently purchased the Anker external battery charger (model 79AN7917) from Amazon.  Today is the first time that I'm charing the battery. When I plugged into my computer using the USB cord provided by Anker, the charging seemed to take a while.  I then tried using the UBS cord provided by Anker and then connected to the white adapter from my iphone 6 and plugged into the outlet.  I thought this might speed up the charging.  Is this correct?  I noticed that after 10 min or so, the blue lights on the Anker turn off even though the battery is not fully charged.  If I plug back into my computer, then the blue lights are back on and one of them is flashing.  Is there any reason why the blue lights on the Anker turn off when plugged into an outlet via iphone 6 white adapter?  I don't think it is charging if no blue lights are on.  Correct?  Is there a problem with my Anker device?   Thank you for your time and help in this matter.

I have this exact same model. When I got mine and plugged it into a wall outlet it would only charge until 2 lights were lit. I tried all sorts if other options Different outlets, different usb cables, etc... What finally worked was a completely different charger. I have a Samsung S4 and when I used that the battery charges right up to full capacity.

If you continue having issues try contacting Support@ianker.com
