Good fit when

  • Capacity is best suited to lighter essentials such as routers, laptops, CPAP planning, lights, and smaller camping loads.
  • Tracked AC output is 660 W, so high-draw appliances and tools need careful filtering.
  • USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
  • Tracked solar input is 100 W before panel, weather, angle, and controller losses.

Watch out for

  • Surge output is tracked, but device startup behavior should still be checked against the actual load.
  • Still unknown in the source-backed record: usable capacity.
