The Wotofo Serpent 50W has the power but not the capacity to serve as a full day vape setup. Although I run low watttage between 40 and 65 watt, I chain vape and need about 6500 mah to see me through the day. Ideal as an in-between vape carried in top pocket though. Dual 26650 and 18650 mods are a bit big to carry in pockets.
Coils for the Conqueror... Would need to experiment as coils are not one size fits all. To start with a SS316L of about 6 to 8 winds 2 to 2.5mm Int dia for a starting point. I generally prefer moderate resistance single coil builds running low wattage with a fairly hard preheat punch, so some fine tuning required.
Only recently got acquainted with the Wotofo brand when I purchased a Serpent Mini 25. Ticks all the right boxes in terms of build, finish, ease of use and fitness for purpose at an affordable price. Although I have limited experience with the brand, I have little reason to expect otherwise from their other products.
