Powkey R350 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.
Quick answer: the Powkey R350 stores 296 Wh. Its continuous AC rating is not confirmed by a usable source, so this record keeps the field unknown rather than guessing — check the sources below before planning AC loads. Last source check: 2026-08-27. This is an estimate, not a guarantee.

AC output stays unknown: the same page rates the model at 300W in its capacity row and 350W in its AC output row. Surge, USB-C, DC and solar ceilings stay unknown for lack of published watt limits.
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.

Conservative assumes harder conditions; optimistic assumes favorable conditions.
- This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.
- The selected station output rating is unknown, so running-load compatibility is not verified.

Good fit when
- Capacity is a compact class; use it for small electronics and short essentials rather than high-wattage appliances.
- AC output is unknown in the current source record, so do not assume it can run AC appliances.
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: ac output, surge output, dc output, usb-c output, solar input.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
