Product title says 300W, while the official table lists 330W rated AC output; keep the table value visible and treat peak output separately.

Runtime Starting Points

These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.

Good fit when

  • Capacity is a compact class; use it for small electronics and short essentials rather than high-wattage appliances.
  • Tracked AC output is 330 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 45 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.
