Desktop vaporizers are bigger and more powerful than portable vaporizers. They are designed to be used at home with a wall outlet. Desktop vaporizers use convection heating, which is healthier than other smoking methods. This means that there is no heat source directly touching the dry herbs and instead, hot air is used to heat the herb. There are two different styles you can pick from, whip draw or forced-air. The whip draw have medical grade tubing that you use to draw the vapors out of the vaporizer. Meanwhile, forced-air vaporizers contain a fan that blows the vapors into a balloon or other attachment. Then, you remove the balloon, suck the vapors out and have a good time.
