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.

Maria, this has been a continuing problem at this forum for a long time and Anker has done nothing about it. People are regularly posting their private personal information thinking that this goes directly to Anker not knowing that this is really a public opinion forum that is seen by tens of thousands of people all over the world. Your request probably won't get seen by anyone important because it appears that the "moderator" is just another Anker customer. Try calling them at 1-800-988-7973 Mon - Fri 9:00AM - 5:00PM PST and asking for the owner (they're not that big) and letting him know how serious this issue is.

Barry Question

I bought my 79AN7917 a year ago. I used it a lot last summer, then not much during winter. I charged it up to four lights at the beginning of summer. Now I charge it for more than six hours, but it never shows more than two lights of charge. First the right-hand light comes on, then the second to right-hand light flahes, but never the third nor the left-hand light. What has gone wrong ?

I was thinking the same thing.  Also does it charge other devices as long as it should?  It's a slim change the two lights don't work.

This device is great so far, just got it from Amazon this morning, thoroughly pleased with it, it will be handy for when I forget to charge my phone, a bit larger and heavier than I expected but that's okay

Charging a Kindle DX Graphite

Well today I'm excited after having received my first external battery, the Astro E3.

The Astro was fully charged so I plugged it into my Kindle DX Graphite to charge that up. The instructions on the Astro E3 say that it will automatically shut off when the device being charged has been fully charged. After charging for about 40 minutes or so, the Kindle showed a green light (which is indicative of full charge) but the Astro didn't shut off. After about another 20 minutes after my Kindle showed a full charge I went ahead and unplugged it from the charger even though the Astro was still lit up (indicating that it's charging). 

Should I just wait for the Astro to shut off or should I wait for the device being charged to show full charge?

Sincerily,

Cole Thompson

The Astro will only shut off when the power being drawn is less than 50mA. It is possible that your Kindle needs more than that to keep charged at 100%. The Astro will therefore not switch off.

Not fully charging

I have my original iPhone 4s 5V/1A charger to charge external battery. According to User manual the 2nd Gen Astro E3 should take 9 hours to charge. I've had it charging nearly 24 hours and can't get more than 2 blue dots. External battery came fully charged and I have fully discharged before recharging. 

What might be wrong?

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
