You read the charge on its screen or in the manufacturer's app and log it here. Estimates are for planning and depend on your appliances and conditions, so always follow your station's manual. CellKeeper isn't affiliated with any power station manufacturer. Calibration may improve reported charge levels; it does not repair the battery or hardware. Some features, such as tracking more stations, planning rolling power cuts with recharging in between and planning solar charging, require an in-app purchase.
