TogoPower Advance 500 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 TogoPower Advance 500 stores 346 Wh and delivers up to 500 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 2.6 hours. Last source check: 2026-08-26. This is an estimate, not a guarantee.

Estimated runtime
4h 25mEstimated runtime: 4h 25mThis setup is tight. Reduce load, use DC where possible, or choose a larger station.
Conservative assumes harder conditions; optimistic assumes favorable conditions.
- This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.

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 500 W, so high-draw appliances and tools need careful filtering.
- 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: battery chemistry, surge output, dc output, solar input.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
