Jackery Explorer 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.

The exact manual identifies a 90W wall adapter and recommends one SolarSaga 100 panel, but neither the manual nor the current support table publishes a solar-input watt ceiling. Compatibility and recharge timing are not treated as that ceiling, and voltage/current ranges are not multiplied into an inferred value, so solar input remains unknown.

Third-party measured tests

These are published third-party measurements for this model. The delta compares measured delivered Wh with WattRunTime's default no-reserve planning estimate for the same output path; it is not a new measurement.

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.

Rated Wh is reduced by efficiency, reserve, battery health, and temperature before it is divided by average load.

Assumptions

  • 294 Wh nominal battery capacity
  • AC inverter output path
  • 85% conversion efficiency
  • 10% reserve kept unused
  • 60 W average load from 1 load
  • 100% battery health
  • 0% temperature loss
  • Fixed station overhead unknown; not included

Warnings

  • 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 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 tracked, but device startup behavior should still be checked against the actual load.
  • Still unknown in the source-backed record: solar input.
  • Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
