I received my Dell G15 Gaming Laptop - 13th Gen Intel Core i9-13900HX - GeForce RTX 4060 - Windows 11 minutes ago. Can't wait to set up but have to put it on hold because we are out of power today. No power, no internet.

I have an immediate questions regarding charging the laptop while plugging in the 14 in 1 docking hub. The Dell has only one USB-C 3.2 Gen 2 port. I guess that's where the docking hub is connecting all those external USB, HDMI, and Card Readers to the computer. I intend to purchase the following AC charger so I can charge the hub, AND the computer without using the AC brick charger that came with the laptop.

Is this diagram accurate depict the scenario? Again, without using the AC charging brick.

The Dell charging brick is rated 330W output, and the Anker Hub said 80W pass through. Is it sufficient to operate/function?

Three hundred and thirty Watts is a hell of a lot of power for a laptop charging brick. But that's what it says. The battery isn't that big, only 51Wh...I can't imagine why the charger supplies that much power. That seems to be too much even for faster charging.

But check the documentation to see if it is even rated for charging via the USC-C port. The USB power delivery specification maxes at 240W.

It was long enough ago that I don't remember the details, and I don't know if this a general or specific problem, but my Dell XPS 13 2-in-1 didn't like the third-party hub and charger I originally planned to use.

The XPS 13 refused to charge when powered via that hub/charger; I ended up buying a Dell HD22Q dock for it.

And WRT your specific question, I see that the i9-13900HX alone has a Maximum Turbo power of 157W (though Dell may have configured it for more or less than that). I personally would not want to provide less power to the PC than the OEM power supply gives.

157W is obscene!

CPU Passmark said the TDP is 55W.

I know TDP is a little different from the power wattage required. But Dell's own owner instruction also said 55W.

What about when I am not plugged in and run on battery? Would that deliver 157W?

My other option would be to buy an extra charging brick and no rely the power from the hub.

My Dell XPS 13+ came with a 60W charger, which I use when I am traveling.

At my desk, I charge it through a 6-1 hub that consumes 15W. So I bought a 90W charger from Dell that works fine.

All these devices use the Power Delivery protocol through USB-C connectors, so I suggest you not get a 3rd-party charger.

I can also recharge my cellphone and tablet with these devices and cables, so that is also convenient.

Ask yourself why it's so big if the laptop doesn't need a lot of power. My Inspiron 16 came with a 65W brick.

That's the Processor Base Power. See that Intel link.

Many gaming laptops slow down on battery:

Slower on battery power | DELL Technologies

I'm running a video process on GPU (RTX 2060) that communicate via socket with another process running on CPU. When the laptop is plugged in, there is no delay either on video or in socket communic...

I think the most taxing task I will be using this laptop for is for video editing. The most demanding part (continuously) is when I export the video. As long as the scrubbing while editing (no even that often) is smooth, I don't mind the export part being slowed down.

I think I am going to purchase the Anker combo and try it out. If it doesn't work, I can always return it and figure another solution. I will come back and report the result.
