VTOMAN FlashSpeed 300 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 VTOMAN FlashSpeed 300 stores 230 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 1.8 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

VTOMAN publishes the FlashSpeed 300 on its European storefront, so the figures describe the 230V EU-market SKU. USB-C output is derived from the published 20V/5A PD profile, which is 100W. VTOMAN publishes no surge, solar input, DC ceiling or weight for the FlashSpeed 300, so those fields stay unknown.
Regional source note: Some specs are cross-checked against official regional pages (eu.vtoman.com: VTOMAN official FlashSpeed 300 product page). Regional SKUs can differ; verify the manufacturer page for your market before purchase or emergency planning.
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 300 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: 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.
