Funny, I see this post as I'm about to pack for a week traveling for work. I spend more time deciding what vape stuff to take when what clothes to take. The usual take setup is an ego pouch with 2 aero tanks, 2 nautilus, for working in the field, my kayfun and trident for evenings, 2 vvv3 with a couple of protank minis or aspires for stealth mode. In my backpack, a repurposed gps case with 5 or 6 juices mad mvp2 with another for backup. At my office it's a VTR or MVP2. The MVPs are perfect for travel. No need to carry batteries and a charger other than a USB charger.
