CTECHI GT-F300D 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 CTECHI GT-F300D stores 1,004.8 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 7.7 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

USB-C and DC ceilings stay unknown because the page publishes no watt limits for those ports. The stored AC figures follow the published 100-120V configuration; CTECHi also lists 220V variants.
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 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: 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.
