Starter kit is exactly what it sounds like. Good starter kits will provide everything you need to start vaping. Like other vape devices, the main components of vape starter kits are the battery and atomizer. An atomizer is the part of an e-cig which contains a coil that heats up the e-liquid to turn it into vapor. The battery is what provides power to the atomizer and coil. JUUL, Aspire Gusto Mini, Joyetech Atopack Penguin, Suorin Air and Suorin Drop are the best vape starter kits currently on the market.
