I'm new to RDA's, I have a Cloud werks RDA. I'm using a GeekVape aegis solo, I put in 1 0.45 ohm Alien Clapton 32gauge A1 coil, not sure if I can put 2 coils in. Anyway I have tried 50W to 100W and get very very little vape out and absolutely massive spitback (burned the F out of my tongue). Can I install 2 coils in this tiny RDA? I need help something is really F'ed up.
