Hi Hentai, and welcome! I have the Subtank Mini, which is very similar to the tank that you have with a larger juice capacity and I love it! What you may want to consider is a more advanced battery with a higher capacity. Take a look at the Eleaf iStick 30 watt. It has a much higher capacity than what you have and it has variable voltage and variable wattage. It's simple and easy to understand and may give you a more satisfying vape experience. Good luck, and ask lot's of questions here. You'll find the folks who come here to be very helpful and friendly.
