A trigger mod was also developed by DOVPO in the 168 model. It's designed to improve ergonomics with any beeping device and support up to 168 W of max power output. The modes here include TC/VW/VV and more. The indicator and changes can all be made over a 1 inch OLED screen. The drop-down menu is easy to navigate and you can just set up your options using the set button for quick vaping.
