There is a vast array of kits on the market. You have starter kits, pod kits, sub ohm devices and advanced kits. Some starter kits will have a built-in battery and come with a charge cable.
Other kits will use batteries that need to be bought separately and you can recharge them via the charge cable in the box. You can buy an external battery charger which can charge 2 or 4 batteries at a time. Always take care when chargeing any batteries and always turn off the charger either if you leave the house or go to bed as these are best not left unattended.
