Powered by two 18650 batteries (sold separately) the Drag 4 will deliver a power output of 5 – 177W. The Drag 4 features four different power modes: RBA, Smart, TC and Eco. If you want more control over the power output, use RBA Mode; or pick Smart mode and the kit will select the best wattage for your coil automatically. Using Eco Mode will save the battery life of the device when it reaches 40% or below. There’s also TC (Temperature Control) mode, which lets you set a temperature at which your e-liquid is vaporised. This helps prevent burnt coils by ensuring that the temperature of your coil remains consistent. Different temperatures also work better with different e-liquid flavours.
