Breathe. You are worrying yourself to no end. I sometimes travel with a small lightweight k-cup brewer in checked luggage and know others who pack their Nespresso units in their carry-ons. If you are concerned about theft, bring a cheapo model and leave the Zojirushi at home. As a typical Alaskan, I'll pack anything and everything allowed in my allotted 2 free bags to avoid astronomical shipping fees (empty bags outbound, crammed full inbound)
