Laptop of these specs won't last a day in general, and they'll also be power constrained in most running profile when straight on battery (you'll be out of power in a few hours if using the full extent of the GPU) Anyone planning to do 3D work in the wild with no power outlet should invest in a (heavy) 100W power bank. Also reliable 100+W chargers will cost an arm and a leg, same docking stations. It's definitely still on the cutting edge and you won't be managing it like a wimpy Macbook Air. Edit: I thought this one had a discrete GPU, but looking at the specs it's not and only needs 65W. Power consumption could be fine ?

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.

    My understanding is that 130W is a proprietary extension of USB C, the spec only goes to 100W.

      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. [0] https://blog.ugreen.com/power-delivery-3-1/ https://blog.ugreen.com/power-delivery-3-1/

        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?

        google only gave me local links (non english blog spam) and that was the most decent among duckduckgo's results. My search situation and skills aren't in good shape.

      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.
