You can buy GaN chargers of up to 180W nowadays, they weigh half as much as regular power bricks and are fairly affordable if you need them. You don't even need to cover the peak power usage and can go with a smaller charger covering regular usage and let the battery come to help when momentarily drawing more power (this is what I do with my Zephyrus G14 + 65W Voltme).
I've been looking at charger delivering 130W on a single port (100W won't unlock the full GPU) and they're not that many.
UGreen and Anker's offerings start at 70 bucks and they're not well reviewed. Docking stations start a triple that and Dell seems to be only reputable maker going these lengths.
To complicate things, many chargers will tout 140+ watts, but only split on multiple ports. Single port output will often be capped at 100W.
The spec only goes to 5A, but as of 2021 the maximum voltage has been raised from 20V to 48V to permit 240W charging. 28V charging at up to 140W is probably the most common mode above 100W; most systems shipping with a power brick beyond 140W are still using proprietary connectors.
The gen3.1 PD standard goes up to 240W [0]. 140W should be available with it.
Of course it also requires gen3.1 cables, so the "which cable do I have" game is still going on.
I have, by and large, stopped unrecommending ugreen since they stopped lying about certificates and now got real NRTL certs for most of their chargers but still how on earth do people find ugreen of all places even for technical explanation? Astounding blogspam!
