Good fit if

  • You prefer adding storage to adding a second station

Look elsewhere if

  • You do not own the compatible base unit
  • 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.

Practical noteWe could not match this battery to a station in our catalog from the listing text. Check the seller's compatibility list before buying.

Fit check before you buy

An expansion battery only works with the units its maker lists.
