Backup battery in Carry On

[Yonah]

Does anyone know if I can take a backup battery like this one with me in my carry on? : http://www.amazon.com/EC-Technology-22400mAh-Smartphones-Tablets-Black/dp/B00FDK2G2C

Yes you just usually can't put it in checked luggage

Just brought a bigger and more terrifying one in my carry on (a bigger one, with aluminum casing, and blinking red numbers ). You have to take it out and put it in the basket where is is fully visible while it goes thru the scanner.

I just brought a 50000 mah one which is huge and I didn't have to take it out separately

They may have not stopped you for not doing it, but they said anything bigger than a cell phone.

+1 Mine wasn't 50,000 but was big, and they didn't say anything.
