CHOETECH BS004 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 CHOETECH BS004 stores 484 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 3.7 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Chemistry stays unknown because this listing publishes no cell chemistry, and surge and DC ceilings stay unknown because the table publishes neither. Values come from the exact-model specification table on the official product page; fields the table does not publish stay unknown. CHOETECH publishes regional AC variants on one page and this record follows the published US/JP configuration where they differ.
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 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.
- Tracked solar input is 150 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: battery chemistry, surge output, dc output.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
