Vapor Source carries a large selection of Box Mods for your requirements. Box Mods separate themselves from other mods on the market due to their ergonomic design, side firing buttons, and depending on model dual battery design resulting in higher output and longer battery life. Typical vape users will only need to charge their box mod batteries once per day or during the evenings depending on build habits and or setup. There are 2 types of Box Mods, Regulated, and Mechanical, Regulated Variable Voltage units give users more control over their vape by the ability to choose wattage and other high tech features that mechanical units do not give. Mechanical meaning a basic push button wired design with no electronic digital chips controlling the voltage between the battery and tank/rda/atomizer. It's a straight through connection to the coils. Users typically use SUB OHM ( lower than 1 ohm ) on regulated equipment which if matched with the right tank/atomizer can lead to longer than usual battery life with full vape benefits, allowing you to make your vape hotter, cooler, another added bonus of most regulated designs with LCD screens is the fact you are able to see what OHM load you're working with to ensure you have a proper RDA build.
