Powkey R1000 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 R1000 stores 740 Wh and delivers up to 1,000 W of continuous AC power. Under this site's planning assumptions (85% inverter efficiency, 10% reserve), a steady 100 W AC load runs for roughly 5.7 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Surge stays unknown because the table publishes no peak AC figure. USB-C, DC and solar ceilings stay unknown: the table publishes PD voltage and current profiles without 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.

Good fit when
- Capacity is best suited to lighter essentials such as routers, laptops, CPAP planning, lights, and smaller camping loads.
- Tracked AC output is 1,000 W, so high-draw appliances and tools need careful filtering.
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, usb-c output, solar input.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
