The solar panel might recharge the unit in six to eight weeks, if a suitable place was available to keep it pointed at the sun during the day. (In other words, it’s absolutely a marketing gimmick, not a real Feature.) (Important note: If sun exposure causes the pack to overheat, thermal runaway could result. So, basically, just don’t go there, mmmkay?)
@chienfou@werehatrack Safety warnings also probably say not to expose to direct sunlight, because the heat from sitting in the sun makes batteries go boom.
30,000mAh, asssuming the simplest 3.6V Li-Poly battery is 108Watt-hr. The solar panel is at best 1W, so only 108 hours in direct sunlight. Figure 5 hours a day and in 20 days, all the rest of the ports will be rusted to the point that the entire thing is an explosion hazard.
This combination of specifications is almost good enough for electrically operated window blinds on a skylight. With a small change, this design would be ideal for all of those buildings with skylights in the same room as a video projector where the builder didn’t think to run power to every skylight.
They don’t include the output ratings for the USB-C. 12 volt motors are a common option for home automation devices, 5 volts is not. The slower quieter motors can operate on less than 30 watts. Since the specs don’t say “PD” and at least 30 watts, these power banks probably can’t power skylight blinds.
If the power banks could drive the motors and they were reliable, then this could be the ideal application for them, assuming the blinds are opened and closed on average once per day. I am assuming it takes at 3 minutes at an average of 15 watts to move the blinds in one direction. They only need the peak wattage to start moving. So a total of 6 minutes per day. That is 15 watts for a tenth of an hour, or just 1.5 watt-hours per full cycle.
The electronics will be inside where the climate is controlled. Assuming there is an air gap between the power bank and the window, there will be enough cooling to prevent solar induced thermal catastrophe.
The power bank is large enough to operate the blinds through two months of extremely cloudy weather. Although, there isn’t much need to block sunlight under those conditions.
This size solar power bank would have an application if only it could deliver 30 watts through the USB-C port.
I first saw motor powered blinds on skylights in a church that was set up for AV presentations. That church did have power run to the right places, so they didn’t need batteries. But who knows, there may be other church buildings that could use these.

But:
Would meh lie to us??

@caffeineguy And that’s if insolation hasn’t heated it into thermal runaway long since. Built-in solar panels like this are such a bad joke.

I think this won’t be allowed on planes.
