I flew from Cincinnati to DC this past weekend. Had no problems with TSA at all. I took 2 ego batteries, 3 bottles of juice, 3 cartos, and my ego charger. Well here's the weird part...I never had to charge the batteries(was only gone for a day and a half), but when I got home and unpacked my ego wall charger was gone and there was a 510 wall charger in its place. ARRGGG!
