Anker 2nd Gen Astro E3 10000mAh External Battery with PowerIQ™ Technology

Anker 2nd Gen Astro E3 10000mAh External Battery with PowerIQ™ Technology

9901 Bluetooth speaker

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.

• Compatible with all Apple and Android smartphones, tablets (including the Nexus 7) and other USB-charged devices. The iPod nano, Asus tablets, the LG G2 and some GPS and Bluetooth devices are not supported.
• To ensure complete safety and best performance, we strongly recommend using your device's original cable, a third-party certified cable (such as MFI) or our included cable.
• The included Micro USB cable is compatible with the Samsung Galaxy S5, Note 3 and other Micro USB 3.0 devices. To connect, insert the cable's Micro USB tip into the larger of the two connection ports on your device.

  • Well designed product, charged two power hungry devices to full easily (Android tablet and phone). One thing to note is charge times, it will take ages to get off that first LED, at least it felt like it, I thought I received a bad battery but low and behold the next LED started blinking. Be patient.Comes with a charging cable but no adapter, you can use another device's after your main device is done charging, their spec sheets provide nice reference guide for amp output to charge time:Adapter Current Output | Charging Time5V/1.5A = 6-7 Hours5V/1A = 9-10 Hours5V/0.5A = 18-20 Hours

  • Recently used this produce on a trip to the UK and it worked exactly as intended. The two days I used it the most I got 3 full charges and a few top offs on my HTC M8. The only con I have is the length of time needed to recharge the pack. I would suggest that you use a charging block that is at least a 1.5a charger. I used an old one that I found in my drawer and it took over 10 hours to recharge it, but once I saw I used a charger from an old phone, the second time I recharged it I used a 1.5a plug and it charged it in half the time. I was able to plan out the recharge times to be overnight so in reality, it was a non issue. Great product, worth the purchase.

  • Great Product, Worth the BuyThis review is from: Anker® 2nd Gen Astro E3 10000mAh Dual-Port Ultra Compact External Battery Portable USB Charger Power Bank - PowerIQ™ Broad Compatibility, Fast Charging
  • This is about the size of a smart phone, only it is a little thicker. It's not pocket friendly but works fine to put in my purse and charge my phone with. I bought one at Walmart for $10 cheaper and it was a P.O.S. This one takes awhile to charge but lasts for at least 3 charges of my cell phone. I was going on a trip and wasn't sure how accessible charging my phone would be so this worked perfect for that. Definitely worth the money if you need it for a camping trip or something! Overall, I'm happy I bought this!

battery doesn't charge
The battery doesn't charge after a day (at least 10 h) in charge, with the original cable.  It was before attached to the pc and after to the normal electric plug but still just one light is blinking. When I try tocharge a device, one light is blinking but nothing happens. What I have to do?

The 2nd Gen E3 is a fairly powerful battery so it requires a fairly powerful input. Please make sure the charger you're using is capable of outputting 5V/2A.

If you're still having problems after this then do get in touch with our customer service guys at support@ianker.com, they'll be able to help you further.

I have noticed when charging power banks that the cable can have a significant effect on the charge going to the device.Not all cables are equal, some are quite lossy(loose power), I have found that a very short cable 12" gives a great charge to my powerbank, however my kindle cable, which is about 3 foot long looses a lot of the charge throughout the length of the cable.Try a short USB cable

Asus Transformer T100
Hi,I'd like some confirmation that this device (2nd Gen Astro E3 10000mAh with PowerIQ™ Technology) can work with the asus transformer T100.The T100 seems to be able to charge with any 2A to 3A charger outlets and fastcharge mode from desktop computer.Oh, and while i'm at it, what's the highest throughput ? 2.1A or 3A on a single port?Regards,Quentin "seedz"

We cannot confirm compatibility with the 2nd Gen E3 as Asus tablets can have issues with a lot of external batteries.

The max output from the E3 is 3A and this can be delivered from a single port or shared between them.

Compatibility with Galaxy Note 10.1
Can the 2nd Gen Astro E3 10000mAh be used to charge a Samsung Galaxy Note 10.1 (original version)?I keep finding conflicting answers online, so would like to get the official Anker opinion! I've looked in the online manual, but can't see anything about this in there...Thanks

LG G2 , Why Not?
Can you explain to me why the LG G2 won't work?  I'd like to buy a couple of the Astro E3, but I notice it said it's not supported.  I really don't understand since it's just a Micro USB? Can you recommend one that would work?  I really like the 10000 range and being able to charge two phones, but both of ours are G2s.

Unfortunately, we're not exactly sure why the LG G2 won't work! It is something to do with the LG G2's charging technology and it can be temperamental with quite a few external chargers. We are working on a fix for this and hopefully we'll have some updated products very soon!

Our E4 and E5 batteries will both work with the LG G2, no problem at all.

Tav

Some questions re cycle touring
Firstly, is it safe to assume that this external battery can be used with either of the Anker solar panels (8w / 14w)?Secondly, is it possible to charge the battery and have it feed power to a device such as a gps or iPhone whilst charging?Thirdly - for overcast days / evening can I use the output from a Son28 hub dynamo  instead of the panels to charge the battery? - I assume not as the output is 6v rather than 5v.Fourthly, in which case, would the battery still charge (albeit slowly) if I use an intermediate device the does output 5v such as the Tout Terrain The Plug III (5v / 500mA)?ThanksGadget links here for reference:http://www.nabendynamo.de/produkte/son_28_en.htmlhttp://www.en.tout-terrain.de/accessories/electric-power-supply/the-plug-ii/

1 - It will be possible for the Astro E3 to be charged with the 14W solar charger but not the 8W (it's output is just a little shy of the required input of the E3).

2 - Yes, it can charge and be recharged at the same time but remember if you do this continuously it could shorten battery lifespan.

3 - The battery requires an input of 5V/2A so if you have anything that can output this or higher then it should work fine.

4 - The Tout Terrain probably will not work as the amperage output is too low. The 3E needs 2A input.

If you need any further clarification or help then give our customer service guys a shout at support@ianker.com.

Awesome Battery
I have a decent stack of batteries in my desk drawer as I've been evaluating them for use at the resort I work for.  We've got an ever growing reliance on portable devices for everything from work order management to activity tracking.  This means a good number of our deployed Ipads and smart phones often end up dying by 3-4:00 in the afternoon.  This battery has been sent out for testing with our event department and has had no trouble keeping 4-5 devices alive all day and night long.While described by many as "Heafty", compared to the other 10,000mAh batteries I've evaluated, this device is sturdy, charges faster then any of the others and weighs less then the poweradd, breett, monoprice, intocircuit , etc that I have tested.

Any improvement in efficiency?
The 2nd Gen Astros and 2nd Gen Astro Pros are all claiming a 10% improvement in efficiency, over the previous productsWill this 2nd Gen Astro E(3) also show the same 10% improvement in efficiency? I don't see the claims anywhere.
