PowerArQ PowerArQ 626Wh 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 PowerArQ PowerArQ 626Wh stores 626 Wh and delivers up to 300 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 4.8 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Chemistry, USB-C, DC and solar ceilings stay unknown because this legacy listing publishes none of them. PowerArQ is a Japan-market brand and this record follows its published 100V configuration; the official product page is in Japanese.
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 300 W, so high-draw appliances and tools need careful filtering.
Watch out for
- Surge output is tracked, but device startup behavior should still be checked against the actual load.
- Still unknown in the source-backed record: battery chemistry, 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.
