The Kangertech Uboat cartridge uses a built-in 1.5ohm ceramic coil and works most efficiently with a 50/50 VG/PG e-liquid. You can expect to get a week or so of use from each cartridge before it needs to be binned and replaced with a new one. The life of each cartridge is dependant on the e-liquid used and style of use.
