I have some coils I built is there a way to vape with them without an RDA
Not really, no. I mean, technically you could just press the ends of the wires up against the ends of the battery and technically it would probably "work," but it'd be a
really bad idea. Probably just best to wait until you can get your RDA.
What are you using, in the meantime? What kind of battery device, what kind of tank(s) do you have? What kind of coils did you build? Have your ordered the RDA yet? What kind is it/or what kind do you want?
I've got a handful of RDA's, my favorites are both clones (actually they're
all clones): a Derringer from FastTech, and a Velocity Mini clone made by Tobecco. They're not really all that similar but, oddly enough, I put the same coils in both of them: dual 6-wrap contact coil 26g Kanthal on a 3mm diameter, comes out about .4-.42 on my ohm meters.
I use them sometimes, to "fog up the room" (not that much though really, haha) when my hands aren't too busy to drip all the time and I'm by my self so there's no one to bother with my clouds, but usually you'll find me puffin' away on one of my Kayfuns. They're tanks, but they're still rebuildable like an RDA. On those I make a smaller, single coil out of thinner wire: 28g Kanthal 8-10 wraps on a 2.5mm diameter, reads around 1.3-1.5 ohms, and gives a much less obnoxious cloud when I'm out in public or sharing a room with other people.
