Anker 2nd Gen Astro E3 10000mAh External Battery

Anker 2nd Gen Astro E3 10000mAh External Battery

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.

Q6.  Will the supplied Micro USB v2.0 cable compatible with the Micro USB v3.0 devices, such as Samsung Galaxy S5/Note2/Note3?
Yes, take a close look at the port and you will see the port is divided, insert the none Micro-USB 3.0 plug to the appropriate side and it will work fine.
Q7.  What's the output efficiency of the 2nd Gen Astro E3 10000mAh external battery?
The efficiency of this battery is around 70%-80%. The internal circuit board is 92% efficient, accounting for power lost through circuit heat and voltage conversion, which is up to 5% above the industry average. Energy is also lost within the charging cable and the device being charged (approximately 15-20%). Additionally, the efficiency can be affected by the cable length and the age of the device being charged.

To extend your battery's life, please discharge and recharge it at least once every 4 months.
Q14.  Can the 2nd Gen Astro E3 10000mAh external battery be used for international travel?

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.

How robust is the e3?
I am looking for a protable battery that I can use every day, and up on the hills - I spend alot of time on the mountains - to charge my iphone if it should run down. Is the E3 capable of holding its charge in cold temperatures? (Below freezing) and take some knocks?

I wouldn't try to push you into something you don't need but I also spend a lot of time in the mountains and I depend on my Anker chargers. I might suggest that you consider the E5. It's always better to have the extra power capacity if you get into a situation where you may be up there longer than expected. Anker can comment on this but I'm not sure if that seam around the E3 would be an issue in damp conditions. The E5 doesn't have it. As far as holding a charge, I have tent camped at 17 degrees F and also at 115 degrees F and my battery worked. Of course I didn't purposely expose it to weather, I tried to keep it snug in a backpack or jacket pocket.

To follow up on what TechToyWizard said, I took have used the battery camping and have kept it in dry bags with clothing when not in use. It seemed to protect it from the colder/damper weather so there was no problems when I went to use it.

The E3 has this safe operating temperature range:

Charge:0~45℃
Discharge :-20~55℃

We do design these batteries to be transported in backpacks so they're not going to break from a few bumps and knocks but we'd always advise avoiding any kind of impacts or drops if possible!

Thanks Anker Team. No piece of electronic equipment should be physically abused. I am sure that Joe J. and Mathew Shelby respect and appreciate that certain gear can save your life in the wilderness. An external battery is one of them. The nice thing is you can leave it in a protected area while you are using it to recharge your device.

Reeks of Quality
I just unboxed my Anker 10,000 mah charger that I had ordered from Amazon a few days ago.  To be honest I've yet to actually use it but that said, I have NO DOUBT it will perform with the same level of excellence I have experience with my two model 3000 "lipstick" chargers.  It was the positive customer experience I've had with those two units which led me back to Anker for a "big honking battery" such as the model 79AN7917 promises to deliver.  Straight out of the package it was obvious that Anker has a serious issue with attention to detail in both the construction and associated literature accompanying this product.  I expected a nicely designed and functional product.  What I am looking at is a piece of art.  The battery itself would not be out of place in a jewely store display case and the accompanying carrying bag is a joy to hold in my hand.  Great job on this one guys!  I'll pop back in once I've had more time to play with it, but I've no doubt it will exceed my expectations and if there is a problem I've no doubt it will be attended to with the same attention to service as you've given to the production side of the equation.  This website is a testiment to that in and of itself.  Keep up the good work!  Now you've got me slobbering over an ever larger "big honking battery".  LOL   Enjoy.

Quote From gherardini: LOL.  I am just guessing here, but I'm pretty sure the Anker team isn't going to be using "Gateway Drug" allusions in any upcoming advertising campaigns.  Pity that!  I'm reluctant to say I would have paid more, and I'm not saying it's aliens, but.....I may not even use this battery it's such a piece of art.  I'm thinking of buying a glass display case and just showcasing it in my home!  Seriously though, with all the cheap junk that's out there it's nice to get something that shows this attention to detail.  Will look good sitting next to either my iPad Mini or my aging 4S.  My application is as professional photojournalist and though I've been bodging by with the Model 3000, this is absolutely the 'pro' version!  Now I'm slobbering over the even larger ones!  Did somebody say gateway drug?   Enjoy.

Quote From AnkerMember431:I wouldn't be surprised since it's probably one of the cheaper Anker products.  My wife actually bought me the first two lipstick batteries.  I bet Anker has the data and could confirm your suspicions if they wanted to pop in here and give their two cents.  They work pretty well on their own accord but since I've expanded out into so many different portable devices it just seemed to make sense to try and shift to one bigger battery instead of trying to shuffle around a handful of lipstick units!  If I add up all the portable iDevices I currently own I'd supposedly have forty hours of power in the devices per day but in actual practice I seem to burn through the batteries in my devices pretty fast.  It's not unusual for me to be running my two ipad mini's side by side with one of my iphones locked onto Google search (with the screen lock deactivated so I don't have to constantlly enter my PIN code.  These bigger units are a godsend to me.  I'll pop back in here in a day or two and post a picture of my photojournalism kit to show everybody how tightly packed I have everything!   I've got the 10000 mah battery and one of the lipstick batteries packed.  I use the lipstick battery to keep my cellular wifi router up and running for extremly long periods of time when I'm out of the office and the new 10k unit for refreshing my more power hungry iPad minis and iPhone. It's certainly a great time to be alive!  Enjoy.

The cable is rated at least 3A as it will charge your devices with up to a 3A output. Just turn the cable around and plug the micro end into the battery and it will charge up to 2A [not limited by the cable] up to the output amperage of whatever charger you are using to charge your battery. HTH.

If you're in bright and clear sunlight then the Astro E3 will be charged in 5-6 hours.

Wire Gauge in Supplied Cable
Hi, I just bought one of these for my wife's tablet (I've had a first gen E3 for a year and it's still going strong). Can you tell me what the wire gauge(s) are in the USB cable you provide?  Is it 28/24 AWG, or something less (i.e. thinner)? I'd like to make sure I can charge my phone at its fast rate if needed, but that requires at least a 24 AWG cable. Thanks

She's got a Dell Venue 7 (Android) tablet, but I'm thinking about charging my phone off it, and in order to have it charge at its fastest I need a cable that's at least 24AWG on the charge side. I've used thinner cables with my 1st gen E3 and seen a big different in charge rate. I'm ust trying to figure out if I need to get another cable to keep with her E3 or if we can use the same one.

Her tablet will pull 10W or 2A from the battery leaving you with 1A left for your phone. Stock cables will work, both from the phone and the one that comes with this should do just fine. Personally, I buy spares to I don't have to carry that cable with for the different devices and Anker's or Amazon cables are of great quality & durability.If you phone needs more than 1A, with the two devices plugged in, they both won't charge at full speed obviously.

Please make sure that the charger you're using can output at least 5V/1.5A. If it isn't that powerful then the Astro may charge slowly or not at all.
