Watch out

  • DELTA 3 and DELTA 3 Plus share capacity and AC output; check the model name, USB-C rating and solar inputs.
  • An extra-battery kit adds runtime; a two-station pack contains two complete stations.
  • A solar kit includes a panel. Check wattage, quantity and whether the panel is bifacial.
  • A DELTA 3 battery bundle is still the non-Plus station.
