The Cool Fire Ultra pushes the envelope with increased wattage and battery life, providing 150W of power with a 4000mAh battery charge. Fortunately, if you've enjoyed the slim aesthetic and ergonomic design of the previous Cool Fire iterations you'll be happy to know it hasn't increased in size given it's upgrades! Awesome!
I now have 3 of them and I love them!
Fits in my hand just right with a long lasting charge life and easy to adjust & use. Highly recommend!!!
Last me all day when running between 60 to 100 watts. Charge is about 1.5 hours. Comfy grip and tanks fit flush even on 2 tanks have protruding positive pins. No issues so far. Very happy with this mod.
I vape @ 45 - 60 watts and this mod lasts all day.
Charges up fairly quick.
Nice basic menu, no lag on the fire button.
Sleek comfortable design.
At this price I'll buy a couple more
Good internal battery mod. Works as well as my 2x 18650 mods . Great for travel or beater mod. Amazing performance and battery life.
