I recently bought a Innokin Coolfire Z Air Set after reading about its compact size and adjustable power, and it’s been pretty solid in my experience. I actually bought a Innokin Coolfire Z partly because it offers three distinct power levels which you can easily switch between, making it convenient to adjust the wattage depending on your coil and vaping style. The MTL design with both 0.8 Ohm and 1.6 Ohm coil options means you get a good range from a looser to a tighter draw, which adds to the device’s versatility. The 2000 mAh battery lasts quite well, so even at the higher power levels, you don’t need to worry too much about frequent recharges throughout the day. I also find the device’s simple layout and button controls friendly even if you’re not a tech-savvy user, which helped me when I was new to adjusting power settings myself. Flavor performance is consistent, and I like how the top-fill system makes refilling neat and fast. Overall, I think it hits a great balance for a compact MTL pod system with adjustable power.
