I am new I have a Cool Fire 1 and it will not function correctly with trustfire 1200mah with PCB but it works fine with the cheapo tangsfire batteries (which I recently learned any xxxx"fire" batteries are low end). I want to buy batteries that will work well in my device and a charger so that I can use My cool fire as my go to vaporizer. What charger should I acquire and what type/brand of batteries work well in the mod? Is it not possible to use a PCB battery in a coolfire because of conflicting trip switches... or is the trust fire battery putting out too much energy and tripping some switch?
