External battery in carry on luggage

Will be taking my first int'l flight early next year to Ireland and will bring along my trusted Ipad. I have a external battery (Anker Astro E5 15000mAh External Battery) would like to bring with me but have heard different opinions that the battery might not be allowed in carry on luggage. The TSA web site is no help so wanted to ask your opinions if I will have any trouble bringing with me in carry on luggage? Thanks!

Not a problem. Who told you you might not be able to take it in carryon? I have never heard anything like that. The only battery-related limitation I have heard was not putting lithium batteries in checked luggage.

Jeff, I'm assuming the battery is a Lithium-Ion model? If that's the case, you MUST pack it in your carry-on luggage as it's not allowed in checked luggage due to the fire hazard. You may find it helpful to have a look at the following website: www.tsa.gov/traveler-information/safe-travel-batteries-and-devices One other point to address is the Charger for your external battery pack. It would be a really good idea to check the "Input Voltage" specifications to ensure that it's designed for multi-voltage operation (ie: both 115 VAC & 220 VAC). The Charger for your iPad will operate fine in Europe. You will of course need Plug Adaptors specific to the countries you'll be visiting. The U.K. style Adaptors are different than those used in continental Europe. Happy travels!

No worries, Jeff. The airplane is not allowed you put battery charger in the luggage, you can however carry one with you. Last time I flied from London and carry my RavPower 14000mAh in my bag, I just successfully went through the check point. Remember don't put it in your luggage.

Hello,for external battery, I have Sumsung phone and Ipad, can RAVRpower charge both of these? I guess there are different specifications between phone and pad.

Talk about some misunderstandings. I thought the ban on lithium batteries in checked luggage was for loose lithium batteries because somehow they might bump into each other and discharge. For the past several trips I have always packed upwards to a dozen lithium AA batteries in my checked bag with no questions ask. Always tape the package so no chance to the batteries getting loose. Now you have me concerned for the next trip.

@Frank,

As you're using AA batteries, Lithium batteries won't look any different on an X-Ray scanner than Alkaline AA batteries. Unless security actually opens your luggage and looks at the batteries, they'll probably just assume they're alkaline and let the bag proceed. I suspect they're more concerned with the larger Lithium-Ion battery packs.

On flashlight-style batteries it's very easy to distinguish between the two on an x-ray.

On an Li, the anode, cathode, and separator are stacked, layered sheets that are rolled up and present a uniform density when scanned from the side.

On a carbon battery the more dense carbon rod down the middle appears in contrast to the materials between it and the outer case.
