What is Innokin CoolFire Pebble?

Several vapers can attest that Innokin is one of the biggest and popular brands in the world. Their vape products have proved to be effective in performance including the Innokin CoolFire Pebble. A CoolFire Pebble with a Slipstream tank is something special to mention in this review.

For years now, Innokin has made a made a name when it comes to the vaping industry. They have manufactured several products on their name like the iTaste, iSub, iClear and more. One of the Innokin’s standard is the CoolFire. It took Innokin a matter of time before they embraced the latest trend of portability.

The CoolFire pebble now competes the CoolFire Mini in compatibility. In fact, it is the most compatible pod system Innokin has ever designed.

The pebble is packed in a small slide-out box that has a small plastic window that reveals the device. All the information is exposed before you can even unpack the device from the packaging.

Once you unpack the device, it looks different from the rest of the Innokin’s products. It is much smaller in design and like other Innokin’s products, it has safety features and other unique features.

It is quite different from other CoolFire devices and we can’t understand why Innokin categorized it under CoolFire.
