Most cigarette lighter ports are 15 amp which would get you 180w max.
I've included the max output per-port (for each of the 4 ports) for those interested.
What's interesting is that this uses true GaN (Gallium Nitride), which is rare in car chargers. This is a good price for a GaN with true 140w max/port that fully supports the PD spec up to ~20v (typical for PD laptop/macbooks). I can only confirm PD at 20v with my use and it's not documented online; there is a reviewer that claims 28v (take that with grain of salt).
I've tried searching for the max amperage listings for each voltage (5V, 9V, 15V, and 20V) as it's not proportional in most PD chargers, I haven't been able to locate that spec.
And a lot are 20 Amp. My 2008 roadster is 20 Amp, as are my newer cars.
Probably in for one. This is a good option for cars with a tunneled second DC. On my car that is the one that stays hot when the engine is off, but there's no way I would leave a 140W charger in that confined space.
no power share between the usb a port and the usb C's when loaded heavily.
