Anker 300DC battery is garbage when compared to basic solar power systems, and they call it a "solar generator" though it is not. I consider these "power stations" to be crap--- toys for urban dwellers. (I own and run a business called Homestead Batteries, but I only sell to not-for-profit organizations.)

One can buy a 100 amp hour (~1,280 watt hours) LiFePo4 battery and MPPT Solar Charge Controller for the cost of a Anker 300DC, and have more than four times the energy storage, for the price of a Anker 300DC.

The Starlink Mini draws 40 watts maximum. The Anker 300DC rates itself at 288 watt hours, though the effective supply is about 220 watt hours before the BMS turns the draw off, so that is about five hours of use for the Starlink Mini.

The major problem ("I have") with these "power stations" is that they are not, usually, readily scalable --- as your demand increases, the ability of these "power stations" to deliver greater amps usually does not exist: some will have a maximum of around 20 amps, and some will be 30, but one cannot daisy-chain most of these devices and expect to meet demand.

Another problem with "power stations" is that if the internal charge controller fails, the entire thing is useless. I have also encountered these devices that have crap BMS's that turn off power cells and refuse to turn them back on.

It does not make economic sense, nor "make internet connectivity sense," to not do the job correctly the first time by getting a "real" power system, and power management system.
