OUPES Mega 5 Runtime Calculator

Use this source-linked record to estimate runtime from tracked capacity, output, charging, and weight fields. Unknown specs stay unknown until an official or manufacturer-grade source confirms them.

Capacity stores the 5,040Wh base station, not the separately advertised 45.36kWh maximum with eight B5 expansion batteries. DC output stores the 12V/30A Anderson path; the car socket and DC5521 ports are lower. The current page is sold out, which is not treated as evidence that the model is discontinued.

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.

  • This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.

Rated Wh is reduced by efficiency, reserve, battery health, and temperature before it is divided by average load.

Source-Backed Next Steps

Good fit when

  • Capacity is in a larger outage/RV class, so the useful question is usually output limits, recharge speed, and weight rather than watt-hours alone.
  • Tracked AC output is high enough for many household plug-in loads, but surge still needs a separate check.
  • USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
  • Tracked solar input is 2,100 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.
  • Tracked weight is in a heavier class; plan where it will live before treating it as a grab-and-go station.
