I know your question was about the juices - specifically, but I thought you may also be interested in the difference between the carts. The liquid in our carts is the same as the liquid we sell for filling yourself. V4L offers two distinctive types of cartomizers: WOW Vapor Cartomizers and CoolCart Cartomizers. There are several differences between the two types of carts; from what type of liquid is in them to how they perform.
Premium CoolCart Cartomizers come pre-filled with Premium Nobacco Liquid and are also sold as blanks. They provide very good vapor and throat hit, but remain cool while being vaped. They are great for chain
vaping or being used with a USB passthrough. They remain cool because they have a slightly higher heat resistance than WOW Vapor Cartomizers. The higher resistance a cartomizer has, limits how much heat is generated in the heating coil of the cartomizer. The Premium CoolCarts have a resistance of approximately 3.4 Ohms. A USB passthrough operates at five volts, so even with the higher voltage the carts remain cooler, because of the higher resistance. These cartomizers also work well on regular batteries, especially if
vaping repetitively with short breaks in between.
WOW Vapor Cartomizers come pre-filled with WOW Vapor Liquid and are also sold as blanks. These cartomizers have a lower resistance so the coil burns warmer. The vapor produced is typically warmer and thicker than Premium CoolCarts. The carts vaporize e-liquid at a higher temperature, so when vaped continuously, they can get warm to the touch. If the cartomizer gets warm, let it rest for a few minutes and it will cool down. The resistance for the WOW Vapor cartomizers is approximately 2.5 Ohms. WOW Vapor cartomizers work best on standard voltage batteries. They can be used on a USB passthrough as well, but they will get warm faster and use e-liquid faster as well.
