My favorite mod so far is Segelei Kaos Spectrum. 230 watts, 2 removable rechargable batteries and a usb port (in case you dont own a charger, which i recommend getting asap)
That will handle the tank you have with the RBA and numerous others, such as Ijoy RDTA Combo. (which beats cloud beast) It is basically an RDA with a tank underneath.. so no dripping.. just tilt as you vape.
Mine cost me $100 Canadian at my local shop.
Advantage.. build anything you want. Remember though.. it isnt about power or resistance or wraps, its about building a coil to max performance. A 6 wrap coil will perform better than an 8 wrap *8 wraps tend to burn in the middle at higher power, faster than the 6* Which is important if you want Clouds Bro. lol
