Like most of the best performing sub-ohm coils, Uforce coil heads feature a big Stainless Steel barrel housing multiple individual coil wires. Uforce U2 coils have a dual coil wire arrangement with a resistance of 0.4 Ohms. Though U2 coils are rated to fire between 40 and 80 Watts, they deliver their best performance between 55 and 65 Watts. For many of the latest high-power mods, this power band is perfect for a high-performance everyday vape.

For even more cloud and flavour, choose the Uforce U4 quad coil design. With wider wicking ports and a resistance of 0.23 Ohms, U4 coils use more energy to generate greater cloud volume. Uforce U4 coils can be fired at settings between 50 and 120 Watts. Unfortunately, reduced coil life and increased e liquid consumption is the price you’ll have to pay if you go beyond the U4 coil’s maximum sweet-spot setting of 80 Watts.
