Litheli B218 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 Litheli B218 stores 216 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 1.7 hours. Last source check: 2026-08-27. This is an estimate, not a guarantee.

Weight stays unknown because the page quotes 8.8 lbs, 2.7kg and a 3.99kg shipping figure that do not agree. Chemistry, surge and solar input 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.

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.

Source-Backed Next Steps

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.
  • 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, 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.
