This is only what I carry with me
Riva 510 (a 3.7v one)+Boge, Joye 510 manual+Boge, Vapor4Life(KR808D-1) manual+V4L WOW carto
All with drip tips as mouthpieces
The Riva usually has a black carto and I do own a Riva 901 cone to fit over a carto nicely but don't bother.
NoSmokeVA.com PCC for 510 but I also store KR8 cartos and one each 510 & KR8 battery in it (it cannot charge KR8s)
And I also carry several small
juice bottles. All fits in an ethnic fabric cross-shoulder little purse with the Riva battery additionally in a Chinese cloth covered lipstick case and wrapped around its middle to keep the button away from the sides.
I vape the two slim models because I like to vape contrasting flavors. One has a cocoa tobacco and one has a very sweet vanilla. I can just pick up whichever I feel like and each refreshes my taste buds for the other. I use the Riva for some bigger hits and as a very portable backup battery.
At home add a nice Joye 510 mega xl manual battery, 2 3.7v mod boxes from ECF modders and a clone Ego 3-stage battery (3.2, 3.7. 4.2v). Nothing exotic yet though the one box mod is pretty - clear blue with an extra bright blue LED.
I also own lots of charger cables, several 4 port 2amp USB to AC adapters for charging, and an 11,000mah portable USB supply which I can charge up ahead of time (needs 7 hours of charging) in case a storm is coming and I suspect we may lose power or for other charging away from AC. Before I started vaping we lost power once for over 4 days so I am paranoid about power loss.
