I am new to vaping and wanted to get a second battery. I purchased a eleaf Istick 30w and it says its a sub ohm. Is there any safety concerns using this with my Nautilus mini tank??
What is the resistance of the coil in your Nautilus mini? With a 1.6 Ohm coil, you should have a good range for adjusting the wattage. However, start at a lower wattage like @Whiskey mentioned, and go higher (step by step) if needed.
