Renogy Phoenix 300 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.

Weight converts the official 6.4 lb value to 2.9 kg. Surge, DC, and solar-input ceilings remain unknown because the checked official sources do not publish them.
Regional source note: Some specs are cross-checked against official regional pages (au.renogy.com: Renogy Phoenix 300 product document). Regional SKUs can differ; verify the manufacturer page for your market before purchase or emergency planning.
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 300 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.
Watch out for
- Surge output is unknown, so do not assume compressor, pump, or power-tool startup will work.
- Still unknown in the source-backed record: surge output, dc output, solar input.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
