OUPES Mega 2 Pro 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.

This is the current US 120V configuration; the separate UK page publishes a 3,000W regional variant and is not merged into this record. Surge stores the US specification breakdown's explicit 3,800W value, while 3,600W Boost Mode remains a distinct sustained-boost claim. Capacity stores the 2,048Wh base station rather than the 10.24kWh expanded system. DC output stores the 1,000W bidirectional Anderson path, USB-C stores the per-port ceiling, and solar input excludes the B2 extra battery's independent MPPT.
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 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 1,000 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.
