The panel is an emergency, not a charging method · review
A 26 800 mAh solar power bank with a 55 W output and automatic power regulation, whose integrated panel is described as a supplement rather than a charging method.
The bottom line The only solar bank here whose listing describes its panel as a supplement rather than a charging method. Nothing about that panel is published — not its area, not its output, not how long it takes.
A 26 800 mAh bank with a panel on it and one honest sentence.
The third bullet describes the integrated panel as converting sunlight into electricity, and as a practical supplement when outdoors. Not as a charging method. Five solar banks in this family, and one of them frames the panel correctly.
A panel the size of a phone case produces a very small amount of power. Filling a 26 800 mAh cell from it alone is a matter of days in good conditions. As a supplement — keeping a bank from draining further while it sits in the sun — it does something. As a primary charging route it does not.
The panel’s area. Its wattage. How long it takes. Not one of the five solar banks in this family publishes any of the three.
55 W, the highest here, with automatic power regulation named. No protocol, no watt-hours, no weight, no ingress rating.

Not published, here or on any solar bank in this family. An integrated panel of a few square centimetres produces a small fraction of a watt-hour per hour in good sun, so filling a 26 800 mAh cell from the panel alone is a matter of days rather than hours. This page does not compute a figure the maker did not give.
The third bullet is honest about it: a practical supplement outdoors. That is the right framing. It keeps a bank from falling further, rather than filling it.
