Each watt-hour it adds costs less than the stations' own ($0.39 on the E1000LFP, $0.36 on the E1500LFP, $0.32 on the E2400LFP, $0.33 on the E3600LFP, $0.34 on the E3800LFP and $0.29 on the F3000LFP), so it is the cheaper way to more stored energy than a second station, which adds outlets and output instead.

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