airstar,
I think you're a little confused on the vocabulary.
Cart=cartridge, a tank for holding juice. it needs to be attached to an...
Atty=atomizer, they are the actual heating element used to vaporize the juice.
Carto=cartomizers, an atomizer and cartridge combined in one. This is probably the unit you are looking for. kr808d-1 typically use cartomizers.
The fluxomizers, etc. mention above are good choices. they are clear plastic cartomizers with no stuffing. I like them, wouldn't use anything else myself.
I like these on a small volt auto battery,
CLEAR AND EASY TANK they are small and very easy to fill. For big fat manual batteries like the igo I prefer the fluxomizers.
