Wattage control is about how much power goes to the heating coil. Higher wattage means more vapor and stronger flavor, but it also drains the battery faster. For CBD-compatible devices, you don't need to blast 60W. A range of 10-20W is typically enough to vaporize CBD e-liquid efficiently without torching it. If you're new, start at the low end and work up until you find what tastes good.

One more thing: wattage is often adjustable, but some devices are fixed. If you're a tinkerer, look for variable wattage. If you just want to press a button and go, fixed is fine.
