CTECHI GT280 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 GT280 stores 192 Wh and delivers up to 200 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 1.5 hours. Last source check: 2026-08-26. This is an estimate, not a guarantee.

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 a compact class; use it for small electronics and short essentials rather than high-wattage appliances.
- Tracked AC output is 200 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: battery chemistry, surge output, dc output, usb-c output, solar input, weight.
- Weight is unknown, so portability should not be inferred from this model page yet.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
