The smart chip allows you to utilize the temperature control mode with better response rate and more efficiently than the iPV4. The iPV4S holds two 18650 batteries with a magnetic back cover that slides off, making it much easier and faster to change your batteries. Pioneer4You has upgraded the OLED display screen making it much brighter than the previous version.
