I believe he is talking about the Accessory ports in his truck.
Mine (all 3 - two in dash; one in console) are wired for 20 amps each (240 Watts each).
If you find you need more power (since mine are home run wired and each has its own fuse), a pigtail connecting the two dash ports together (with appropriately sized wire and fuse) could be used to get the full 400 Watts from the inverter, if needed.
