i picked one up yesterday, and i have been using the Cerabis tank exclusively now. using the 0.9Ohm coil at 35W.
tried it at 60W and its awesome flavor, nice and WARM vape, but i have a single battery device, so it chows battery
im hoping the 0.5ohm coil will let my battery last longer as it will require less volts for same wattage.
but all in all this tank is winner. and if these coils last as long as they say then this will be the most economical tank ever, even if it just lasts a mont, then i will be happy!
Um, I think the opposite is true actually. Battery charge is rated as milli-amp hours, so how long it lasts depends on the current being drawn. Current (amps) is voltage divided by resistance. Power (Watts) is current times voltage. Little bit of math means that the 0.5 ohm coils will cause higher current drain at equal wattage than 0.9 ohm coils.
