Good fit if

  • You prefer adding storage to adding a second station

Look elsewhere if

  • You need more output watts — an expansion battery adds energy, not power

What it adds

An expansion battery adds watt-hours to a compatible power station without adding output: the base unit's inverter still limits how many watts you can run, but you can run them for longer.
