iTechworld PS800 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 iTechworld PS800 stores 512 Wh and delivers up to 800 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 3.9 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

USB-C stores the published 20W output ceiling; the separate 100W figure on the same page is a charging input. Surge and DC stay unknown because the page publishes neither. iTechworld is an Australian brand and this record follows its published 240V configuration.
Regional source note: Some specs are cross-checked against official regional pages (itechworld.com.au: iTechworld PS800 official Australian product page). 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 best suited to lighter essentials such as routers, laptops, CPAP planning, lights, and smaller camping loads.
- Tracked AC output is 800 W, so high-draw appliances and tools need careful filtering.
- Tracked solar input is 200 W before panel, weather, angle, and controller losses.
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.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
