BLUETTI B500K 5,120 Wh of LiFePO4, for the AC200L and Apex 300.
$1,999 at BLUETTI, checked Oct 14, 2026 : $0.39 for each watt-hour it adds .
Each watt-hour it adds costs less than the stations' own ($0.44 on the AC200L and $0.58 on the Apex 300 ), so it is the cheaper way to more stored energy than a second station, which adds outlets and output instead.
From BLUETTI's published figures and our own arithmetic; we have not tested it ourselves.
