Well I bought my alien 220 watt 2 days ago and have been using it at a hundred watts . Anyway decided to bite the bullet and try my cloud beast at 220 watts full power. It's a nice vape . I'm using the innokin 30 amp batteries which I believe have a 20 amp continuous discharge rate. Didn't blow up or anything. Just really wanted to try the alien out to see what it could do. Awsome.
