Anker Astro E5 15000mAh External Battery

9901 Bluetooth speaker

Product Description

With such massive capacity, in such a compact package, the Anker Astro E5 is perfect for flights, road trips, or just any time you’re away from an outlet.

Enough power to go around.

Marooned? In transit? Forget your OEM adapter? With the Anker® Astro E5, prolong your battery life multiple times, wherever you are. Holding enough power to charge a smartphone 4-7 times (depending on your phone’s battery size), keep your gadgets going for days and still have juice left to share.

World's most compact 15000mAh Battery.

Innovations in battery cell technology allow us to pack more power into less space – making this the most compact ever 15000mAh external battery. In addition to portability, the Anker Astro E5 sports two concurrent, high-speed ports. So whether you're charging an Apple or Android device, you won’t need to wait around.

Designed around the details.

Just because the E5 packs a punch, doesn't mean it can't look nice. We went with a smooth, ebony/ivory finish to keep you traveling in style. Simple, unobtrusive features, such as one-touch status LEDs and a built-in flashlight, give you everything you need out of a battery without sacrificing aesthetics.

For optimal use

- 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.
- For simultaneous, max-speed charging of your Astro and other devices, check out Anker's new 25W 5-port wall charger or dual-port 24W car charger.
- Compatible with all Apple and Android smartphones, tablets and other 5V input USB-charged devices. The iPod nano and some GPS and Bluetooth devices are not supported.

Customer FAQ

Q1.  Can I use USB cables othan than those provided with my Anker external battery?
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.
Q2.  Does it work with the new iPhone 5s, 5c?
Yes. But the Apple connector is not included. Please use your device's original cable.
Q3.  Anker external batteries' efficiency.
ALL external batteries lose power due to voltage conversion and circuit resistance.

Approximately 20% of Astro 2nd Generation external battery’s total capacity is consumed, including power lost from circuit heat and voltage conversion within the external battery (approximately 6%) and the charging cable and your device (approximately 14%). This efficiency rate is 15% higher than the industry average of 35%.

Older Astro batteries have lose approximately 30%.

According to industrial standards, all external batteries are labeled based on their raw cells capacity not efficiency. Like others, we are following this standard.
Q4.  How long will the battery lasts while not in use?
Generally, most of our external batteries' static power consumption is lower than 100uA, which will take between 3.5 and 20 years to drain the battery completely.

However, the chemicals within the li-ion battery will gradually become less active over prolonged periods without use. Most will die in 2 years of inactivity.

To extend your battery's life:
1. Charge and recharge it at least once every 3-4 months.
2. Do not over-charge or over-discharge it. It is best to keep it charged between 5%-95%.
Q5.  Can Anker external batteries be used for international travel?
Yes. Be sure the USB adapter you bring with is compatible with the voltage of the country you will be traveling to. An adapter's voltage input is usually printed on the adapter.
Q6.  Can external batteries be taken on board airplanes?
Yes, all Anker external batteries can legally and safely be taken on board airplanes. Here are the relevant requirements:

Quoted from Federal transportation security rules (Effective January 1, 2008):
Lithium ion batteries (a.k.a.: rechargeable lithium, lithium polymer, LIPO, secondary lithium).
-Passengers may carry consumer-sized lithium ion batteries [no more than 8 grams of equivalent lithium content or 100 watt hours (wh) per battery]. 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 Pro 20000mAh (74 wh) which is lower than the above 100 wh limit.
Q7.  What can I do if I lose the provided accessories?
Please check to see if you have extras or contact us via email at support@ianker.com for help.
Q8.  Anker external batteries' compatibility
Anker external batteries are compatible with Android and Apple smartphones and tablets except Asus devices ( Apple connectors are not included, please use your devices original cable).
Q9.  Can it be charged and charge other devices at the same time?
Yes, this battery can simultaneously charge and discharge. However, constant pass-through charging may affect the battery’s lifespan.
Q10.  Do I need to press the power button when charging other devices?
Yes.
Q11.  Do I need a certain type of charger to recharge this Anker external battery?
No, most USB AC chargers or a laptop or PC's USB port can recharge this battery. A minority of USB AC adapters are not compatible. If you find your charger is not working, please try a different charging option.
Q12.  How long does it take to fully charge this Anker external battery?
9-10 hours with a 1.5A output charger. Using a charger with a lower current output will prolong the charge time.
Q13.  How to turn the flashlight on and off?
Please press the power button twice to turn the flashlight on or off.
Q14.  Can I charge two devices at the same time?
Yes. But please note that when using 2 output ports simultaneously, the total output current will not exceed 3A.
Q15.  Can it charge Samsung or Asus tablets?
No.
Q16.  What if the Astro E5 fails to recharge?
a. Check that the adapter is connected securely, or replace it if the current one is not functioning normally.
b. Check that the USB cable is connected securely, or replace it if the current one is not functioning normally.
c. Please email us at support@ianker.com duiring your 18-month warranty period if the provided acessories or the external battery have problems.

c. Check that the Astro E5's voltage is compatible with your device's.
d. Please email us at support@ianker.com duiring your 18-month warranty period if the provided acessories or the external battery have problems.

Anker do a wall charger,  the battery has a 1.5amp input,  in order to charge the unit quickly,  the charger needs to be able to supply 1.5amp, the Anker chargers can supply 2.4 amp. The battery will only take the amps it needs,  so have a look at the Anker wall charger

The wall charger you need should be capable of outputting 5V/1.5A.

Currently in the UK we only have stock for our 5 port chargers, they do have Power IQ installed though which means they'll charge any of your devices at full speed.

You'd just need to search on Amazon for 'Anker 25W Wall Charger' or 'Anker 40W Wall Charger'.

If you've tried using a different Micro USB cable and the E5 is charging up OK then this would indicate a fault with the cable, in which case we'd be more than happy to get you a replacement sent out.

Give our CS guys a shout at support@ianker.com and let them know the situation. They'll help you out.

Hi,I have tested my battery with another functional Micro USB, it did not work. I have also connected my Micro USB to my friend's external battery(anker), it worked. After that cross check, it was cleared up that the problem is originating from the battery itself. Could you please give me en advice to find a technical service in Turkey in order for me to keep in touch with them and send the battery for repair. Thank you.

Better Than The AC Outlet
I just recently received my E5 15000mAh and it blew me away.  I connected a Samsung Galaxy Note Pro 12.2.  The charge time was significantly less than the wall charger that came with the tablet.  The unit is well constructed, has easy to use functionality, and the ergonomics and appearance are first class.

I bet your wall charger is about 1A... throwing a 2A output at devices makes a significant difference! Sometimes I use my battery just because it charges way faster than the OEM chargers. But them I got the 40W 8A charger too, no problems any more.

Anker Astro E5 1500mAh
I recently purchased a new Anker Astro E5 15000mAh External battery that I received around April 10, 2014.  I have used it maybe three times to charge my Iphone 5c and it worked great.  I noticed yesterday that it no longer shows the 4 lights after a full charge.  I purchased the appropriate USB adapter for it and tried charging it that way and also on my computer and it only shows the two blue lights on the right.  The light on the far right was blinking as if it receives a full charge, but the two lights on left do not turn on at all.  Hoping you advise as to what is going on with the device.  Thank you.

If you have already tried different wall chargers and a different Micro USB to USB cable and it's still not working then it might indicate a fault.

Please get in touch with our customer service guys at support@ianker.com and let them know the problems you're having. They'll be able to help you out further.

With the specialized signals required by some Samsung products you're better off going with the 2nd Gen Astro3. The energy efficiency is higher so you actually get about the same amount of usable power as the Astro E4.
