Q14. Can the Astro E5 15000mAh external battery be taken on board airplanes?
Yes, all Anker external batteries including the Astro E5 15000mAh external battery 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 Pro2 20000mAh (74 wh) which is lower than the above 100 wh limit.
Q15. What should I do if the Astro E5 15000mAh external battery can not be charged?
Please try a different AC adapter and Micro USB cable to see if that helps. Email us at firstname.lastname@example.org during your 18-month warranty period if this doesn't fix the issue.
Q16. What should I do if the Astro E5 15000mAh external battery can not charge other devices?
Please try a different charging cable between the Astro and your device. Email us at email@example.com during your 18-month warranty period if this doesn't fix the issue.
