This is 2nd generation product that can turn any DC input 5V-24V into a full PD 3.0 USB C output. This works perfectly with SlimQ F150/F240 and upcoming F330 chargers. Those chargers have a DC output of 20V with 5.5x2.5mm connector. It also works for 12V DC output from car cigarette lighter or battery.
The highlight of this extender is that it has voltage boost. For example, your DC input is 12V, it can still boost the voltage to support 20V in PD 3.0 standard.
