Innokin Cool Fire Mini Slipstream Vape Kit This is a smaller version of the best selling larger Innokin Cool Fire mods, it's about two thirds the size of the Cool Fire TC100 to put it into perspective, & weighs a fair bit less too. The Cool Fire Mini mod will fire up to 40 watts & the 1300m Ah internal battery has been designed in an ergonomic shape, & at only 63mm tall, it's a very convenient size to carry around. The fire button is now curved for more comfort & the bright OLED display screen clearly displays your necessary vaping data. The high quality stainless steel 510 thread & gold-plated spring-loaded connector pin are compatible with all standard coils & tanks. As you'd expect, charged via a micro USB (Universal Serial Bus) cable via your PC or laptop & you can vape while you're charging.
