Powkey R2000 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 R2000 stores 1,728 Wh and delivers up to 2,000 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 13.2 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. Capacity stores the 1,728Wh figure published in the product name and specification table; the page URL still carries an older 2,016Wh value. 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.

Good fit when
- Capacity is in a mid-size planning class that can cover many overnight or essential-load scenarios when reserve and efficiency are included.
- 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.
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.
