Each watt-hour it adds costs less than the stations' own ($0.52 on the F3800 and $0.62 on the F3800 Plus), so it is the cheaper way to more stored energy than a second station, which adds outlets and output instead.

From Anker SOLIX's published figures and our own arithmetic; we have not tested it ourselves.
