Box mod kits come in all shapes and sizes from mini box style kits to large 200-300 WATT producing kits. Box mod kits usually come with tanks, coils and accessories. Some have built in batteries and some require you purchase additional batteries. Always read the description to see if you need to purchase additional batteries. Box mod kits are popular as they generally offer larger battery capacity (more power and last longer) as well as coming with digital screens allowing you to adjust everything from wattage to coil type to advanced features.
