what is 30 watt? get a 100w dc plug pd charger, and a usb c 100w cable. then it will charge up to 100w or whatever the all in one will accept.

I have not tried this on a laptop, but I did test it for charging a cell phone.

This USB port + 150 watt solar panel with a Vmp ~ 18 volts. No battery, just connected.

It is cheap enough to try and very simple to set up.

Like this one which has terminals to hook to battery
Says 96w .... but its really only 30w

You have to feed 24 volts to the higher power USB ports to get the higher power modes.

They work by increasing the voltage from the traditional ~ 5 volts, and stepping it up to the level that both the charger and device both can deal with.

Some need 48 volts for full power.

The model i have link.
Its on my 12 volt lifepo4 battery and do 65watts output on my laptop.
Its 65watt dp port .
And it have lose fast q-charge port .

I have test it my self so i know it works .
Even if i use boths port the same time.
I run 2 years like that.

um no.

i routinely charge multiple items including laptops. with pd 100+ watt chargers.

I just charged a Lifep04 100ah battery with a pd charger and a usbc trigger cable.

Interesting. That is an unusual unit.

To get full power though - still requires 24 volt.

Read note 1 in the description of what you linked to.

sure

"USB-C1 port can output 5V-28V voltage when the input is 12V"

You only get 1 port capable of it with a dc plug, due to the wiring fuse limits in cars. You need ac plugs to get more wattage.

Nope 12v all you need.

Wy explain?
Its nothing more than a dc to dc charger

Most are limit by 10a
12x10= 120watts
Reason is that the car plug is rate for 10a .

We can make 12volt to 230volt 5000watts.
But not a laptop adapter that is 19volts
Lol
