What USB-C PD Adpater can I use with my HP Spectre 15-DF1043DX

[Modify_inc]

I'm trying to find a USB-C PD adapter that I can safely use to charge my HP Spectre model: HP 15-DF1043DX. The power specs on the back of the laptop state 19.5v and 6.9a, so multiplying those means I need a PD of 135w, correct? I see listings of 135w or greater when searching, but after reading, they usually state that is the total wattage, while the individual ports max out at 100w. I did see that Apple has a 140w USB-C charger, though it didn't state if that's a total wattage or per port.

Can someone please help me find a USB C charger or suggest one that will charge the battery for this laptop?

Its specs

It uses  135 W Smart AC power adapter part # L15534-001.  I can't find a compatible USB-C charger for the whole series of 15-df1xxx machines. It has 2 Thunderbolt™ 3 ports, I don't know why  HP does not supply USB-C charger for the series.

In theory, any Thunderbolt™ 3 chargers with wattage rating 150W or above should work.

Regards.

The manual states the USB-C ports on this model use PD 3.0. From my understanding, PD 3.0 maxes out at 100w, which is 35w less than the required 135w for this laptop. Maybe that's why HP doesn't provide a USB-C charger for this model. Though why would HP provide these USB-C charging ports knowing that PD 3.0 is underrated for the 135w required for this laptop?

If my understanding is wrong, someone please enlighten me.
