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.

  • Anker astro e3
  • The charger is about the size of your average 5 inch smartphone, maybe just a little taller and thicker. It definitely is heavier than most smart phones but overall it's not too bulky. The button on the front if mine that you push to see how much charge it has left does tend to stick occasionally after being pushed. The build quality as a whole though seems good. The shiny black looks very good, but definitely gathers fingerprints very easily and seems pretty easy to scratch, mine has some scratches on the back just from setting it down on my desk. The mesh bag that it comes with is great. You can still see the blue lights on the front when it is in the bag and you can charge your devices while the charger is in it's mesh bag. The charging cable included is about 2.5 feet long. The one that came with mine was pretty loose on the micro usb end when connected to my phone, but I contacted anker and they sent a replacement which is much better. Anker has excellent customer service. The IQ charging seems to work well and has had no problem with any device I have plugged into it. Overall this is a good charger that does what you need it to do.

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?

Absolutely. I charge my ForeRunner 610 and Edge 810 with several of Anker's batteries all the time. Even mounted a Mini 3000 battery to my bike stem to keep the 610 charged when I was out for rides longer than it's 5 1/2 hour battery life.

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.

No, the supplied cable should be fine.

The cable will handle anything a USB output can give.

Astro E3 with 14W solar charger
   Hello,I have the 14W solar charger and would like to know if the Astro E3 would work well with the solar? How long is an average charge take with solar considering full sun? And which battery would you recommend that works well and charges relatively quickly with solar to be used for charging iPhones and iPads? Thank you in advance.Allen

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

The E3 is also a great choice to be used with iPhones and iPads as well as with the solar charger.

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.

Anker Recharging Issues/Questions
Hello, thank you for taking the time to read my post. I just bought this product and had concerns with recharging the power bank. I plug in the power bank to charge overnight (12 hours) and it tends to stay at the same circle power range or only rises to the next power circle (25% more). How do I get the optimal charging conditions? Im using the usb/micro usb cable the anker came with and a usb wall adapter. And when I plug in the power bank does the circle need to keep blinking to signify its charging? Or does it only need to blink 3 times then stop? Im afraid my device's recharging capabilities are slow or defective. Thank you.

The leds will blink indicating the charging process. See if you can find another AC adapter preferably a 2A one for fastest charging.

Please make sure that the wall charger you're using can output at least 5V/1.5A, if it can't then you may find the Astro charges slowly or never reaches 100%.
