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.

  • Backpacking power pack
  • I bought this to take on a 9 day backpacking trip in CO to keep my phone charged so I can use the camera. For lightweight backpacking this is definitely a luxury weight item at half a pound, but for everyday use it's not bad at all. I chose it because it had the most capacity while still being quite a lot lighter than a solar panel and batteries. It doesn't rely on having sun to charge and doesn't have the hassle of setting it up and taking it down like a panel. I will only be using it for one device but the extra port is nice for redundancy and in case someone else needs a charge too. The capacity is GERAT! I can get 3 full charges from a 20% battery on my Galaxy S5 which will easily last more than 9 days with the phone in power save and airplane mode. I tried a friend's Goal Zero and only got one charge from 20%. If you are thinking of buying know that it is heavy, but it seems to be a great product and does what it's supposed to. I will post an update after the trip.

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.
Q16.  What should I do if the 2nd Gen Astro E3 10000mAh external battery can not be charged?
Please try a different AC adapter and Micro USB cable to see if that helps. Email us at support@ianker.com during your 18-month warranty period if this doesn't fix the issue.
Q17.  What should I do if the 2nd Gen Astro E3 10000mAh external battery can not charge other devices?
Please try a different charging cable between the Astro and your device. Email us at support@ianker.com during your 18-month warranty period if this doesn't fix the issue.

Discharge time for light indicators?

Dear Anker Team,

I am an LG G2 D802 user and I mostly use my Anker 2nd Gen Astro E3 (Model 79AN7917) to charge my G2 mobile handset. I have observed that the time taken to discharge (in light indicators going off) seems to be different for these 4 light indicators. The first two (or top 2) get discharged relatively quickly than the remaining two.

 

Is my observation correct or not? If the discharge time is different, then how much time each light indicator takes to charge?

Regards,

CA. Kunj Agrawal

Sorry to hear you're having issues.

Unfortunately the G2 is listed as an incompatible device on all our sales pages. This means that we can't vouch for performance when the Astro is used with the G2.

If you could try the E3 with another device and see if the performance is still erratic then our customer service guys will be able to help further at support@ianker.com.

I recall Anker saying they changed the sourcing for their batteries recently and have gone with name-brand cells. It appears that the cells themselves are all of one type, as g details above.

Well, if I go read the FAQ for the E3, I find that Anker explicity states that the batteries are Li-Ion. Q13. If you have such a big desire to find out, maybe spend more than 30 seconds reading some other review and actually read the manufacturer's product page.

This specific one is Li-ion but we do have some that are Li-poly.

Always try changing all the charging components first, the cable and the charger, before blaming the battery. But once you have verified that it is, indeed, the battery misbehaving, send a message to support@ianker.com and they will get you sorted.

Power IQ charging iphone 5s

Hello. I have a question about this battery. When I charge my iPhone 5s overnight with this battery it still charges my phone the next morning. The battery does not shut off automatically. Does power IQ supposed to have this feature? I once had an older model the astro 5400 mah and that battery actually shut off automatically. As far as I know to my knowledge of power IQ it supposed detect when your device is done charging. Sometime last year this battery was sold out on Amazon. I'm a little confused about this. Was this feature removed? Can someone explain this? By the way I actually bought this around January 2015 when this item was in stock again. I wonder if these newer ones that you got in stock might have some wrong. Thank you

>> The battery does not shut off automatically. Does power IQ supposed to have this feature?

Of course, it does.
My E5 2nd gen shut automatically down after complete charging.
The only doubt could be about the integrity of the 5S battery, means to be still able to charge fully, but if you said another battery shut automatically off after charging, maybe it's a powerbank issue.

This may be because your phone is still drawing more than 0.05A when it is fully charged. Please try with your phone switched off and see if that helps.

Dell Venue 11 Pro Compatible?

I am interested in buying an Anker external battery to be backup power for my Dell Venue 11 Pro model 7130/7139.  Would the Astro E1 be compatible with that tablet (even if it may not do a full charge)?  How about the 2nd Generation Astro E3 or E4?

Fully drain before recharging an E3?

Should I wait until the E3 is fully-drained to recharge it, or can I top it off whenever it's convenient?

Replies(4) Collapse Report as spam Feb 21, 2015 at 8:12 AM

Hello,
modern batteries does not keep a "charge level memory", so you are free to charge it when you are comfortable.
The life of a battery is measured by "charging cicles", calculated not simple basing on the number of charges (partial charges), but on the number of "complete charges" instead.
I don't remember exactly the number of cicles declared from Anker before the battery begin to lost efficiency, but it seems about 1000 (that are more than one COMPLETE charge per day, for 3 years).


So, if you do, for example, 2000 "half-charge" it sould be the same of 1000 "complete charges".

However, it's a good practice to do a complete discharge and subsequent complete charge one time per month.

Not complete though, LI batteries last longest if you run down to 5% and charge to 95%.

Good answers above. There are as many answers about Lithium batteries as there are questions. But the OEM manufacturers suggest a 100% drain at least once a year.

Just whenever is convenient!

We'd just suggest not leaving it at 0% or 100% for extended periods.

Pass-through charging is NOT recommended by Anker, and in fact they are looking to disable this capability in the firmware of their batteries. It does not good things to battery life.
