FAQ

Q1.  Can I use USB cables other 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.
