Hi, I'm new to this forum. I own a suorin elite and I've been having a lot of problems with it the past couple days. The wattage keeps going down to 20w. I'm not sure what to do about it. It keeps thinking there's a different coil in it and keeps setting it to a lower wattage. Sometimes even when it detects the right wattage it'll still take it down to 20w. What do I do?
