The popularity of portable vaporizers is also growing due to the rapid evolvement of vaping technology. If you want to vape in different places or you travel a lot, a portable vaporizer is the best choice for you. It is slightly larger than a pen; thus, it can be carried along when you are on the go. Comfort is the key when it comes to portable vaporizers. They must be easily packed and taken wherever you want. Most portable vaporizers are rechargeable, but there are also types using butane and fire for heating.
