If you are looking at Evod tanks, check out the Evod Glass. It is reasonably priced, and my daughter and I like it better than the Protanks that we had originally gotten.
Evod Glass comes with a Kanger dual coil. However, you can use an Evod Glass tank with a Kanger single coil - I am using one right now. Whether you use single or dual coils on it, your battery should not have a problem with this tank. Before we upgraded our batteries at Christmas, we were using the Evod Glass tanks on Kanger Evod 650 mah batteries, and had absolutely no problems with the battery being able to handle dual coils. My daughter prefers the dual coils, I prefer the single coils.
My daughter recently invested in a Nautilus Mini tank for herself, and she is really enjoying it. Once things settle down financially for our family, I plan to get one for myself.
Please remember that regular Evod or Evod 2 tanks are plastic, and some eliquids can damage or destroy plastic tanks. The Evod Glass, like the Protanks, is glass, and can handle any eliquid. The Nautilus Mini is also glass, and seems to be very well regarded here on ECF. Just be sure, if you get the Nautilus Mini, to get the BVC replacement coils, not the BDC coils.
