OMNIBAR Vanta 4000 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 OMNIBAR Vanta 4000 stores 4,096 Wh and delivers up to 4,000 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 31.3 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Surge stays unknown because the page quotes a 4096W 'peak' that matches the capacity figure rather than a distinct surge rating. Solar input stays unknown because the dual-input 1600W figure is not attributed to a single documented ceiling, and DC and weight are not published.
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 larger outage/RV class, so the useful question is usually output limits, recharge speed, and weight rather than watt-hours alone.
- Tracked AC output is high enough for many household plug-in loads, but surge still needs a separate check.
- 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: surge output, dc 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.
