Personal Vaporizer E-Cig - Innokin - CoolFire IV - Express Kit 

Innokin CoolFire IV at ECBlend FlavorsWith 40W of vaping power, the CoolFire IV fires a full range of resistances and each is made with the highest quality materials to create a vaporizer that you can rely on!  

The CoolFire IV is the newest and most compact, intelligent, and powerful vaporizer from Innokin Technology.  Their teams of expert engineers and designers have packed the CoolFire 4 with the most advanced and integrated vaping technologies to create the perfect compact sub ohm e-cigarette.  

The Cool Fire IV uses Vrms DC current and is very accurate with a power deviation of 0.1Watt. The full 40 Watts is precisely maintained between resistances of 0.3 to 2.5 Ohms. There is no wasted power and exact accuracy means you are always vaping the power level that you choose. Vrms provides superior precision in delivering the exact wattage requirements, and stable power means better vapor.

Please read all WARNINGS on this product.

Shaking and Steeping: ECBlend E-Liquids are made fresh at the time you order and shipped quickly. Steeping allows flavors to blend and marry fully over time, so you will have a richer, deeper, more flavorful product after a few days or weeks of steeping. (This is especially true of tobacco flavors, our Dragon Series, and larger bottle sizes.) Store in a dark cool place, out of reach of children and pets. Shake daily.

Important Notices:
(Select Options with Care: Options are available to mix and match to suit your taste. Care should be taken to not over flavor, (i.e. adding double extra flavor plus extra menthol plus double sweetener plus flavor shots will alter the original recipe and may give it a metallic or medicinal taste.) Always order a 5ml bottle before ordering a larger size.)

DOUBLE Extra Flavor WARNING: Double extra flavor can change the intended flavor of a blend. CLICK HERE to read FULL WARNINGS
EXTRA MENTHOL WARNING: Extra Menthol is very minty, order it at your own risk.
TASTE IS SUBJECTIVE: We recommend trying a 5ml bottle before ordering a larger size.
CUSTOM E-LIQUID - NO RETURNS, REFUNDS or EXCHANGES: Due to personal tastes and preferences we are unable to offer returns, refunds or exchanges for e-liquid products.

Warning about Polycarbonate Tanks: Use Polycarbonate tanks with e-liquid at your own risk. NOTE: If your tank becomes cloudy or begins to crack, discontinue use of the tank. This usually indicates the plastic is polycarbonate. NOTICE: WHEN NOT RECOMMENDED FOR POLYCARBONATE TANKS. It is best to use a pyrex or glass tank or a non-poly carbonate tank.

  1. Personal Vaporizer E-Cig - Innokin - CoolFire IV Express Kit works great 5 Star Review

    Posted by on 21st Oct 2017

    love this so much works just great

  2. Personal Vaporizer E-Cig - Innokin - CoolFire IV Express Kit Third Coolfire IV 5 Star Review

    Posted by on 7th Nov 2015

    It's lighter than my IPV mini, fits perfectly in my hand and it looks great. It autoscrolls fast! when adjusting the wattage and I love that I can vape a .5 ohm RDA on it, or lower the wattage and put a 2.4 ohm BCC on too! When I run a 2.4 ohm BCC on it (what I use when I'm out and about), the battery lasts all day and then some on a single charge. Running a .5 ohm RDA on it, the Coolfire IV lasts me around 6-7 hours. Fires perfectly every, single time.

    The quality and durability of the CoolFire IV is in line with what I expect from Innokin. Whether you're looking to get a regulated sub-ohm device or a nice PV for running around town with, this, IMHO, is the best one out there! It's perfect for the new vaper or the vaping veteran.

Thank you for your comments!
