Calculations

After checking in and going through Narita sceening, I was asked if I had a battery in my carryon and was asked to show my extra battery. There are 2 ways to calculate a lithium battery, in mh and mAh for travel. In the States it is 100-160 mh and in Asia such as Thailand, they say in mAh. 20000 mAh divided by voltage which is 220v there gives one 90.90 mh. The United States FAA required all lithium batteries to be in one's carry on and is forbidden in checked luggage. Just Google "lithium battery FAA" and see. The leading smart suitcase manufacturer that had lithium batteries built in to their suitcases just went bankrupt this week because of this.
