Worst airport experience ever and it wasn't my first time here. They took my battery pack simply because they couldn't read clearly the capacity label. Had a 2nd one as back up which is the exact same battery but it was ok cause they can read the label. Same battery so it makes you wonder. So if you plan to travel with one make sure the label is easy to read or else they will confiscate it.
