What this evidence cannot prove

  • No Find My Generator hands-on test, instrumented load test, teardown, or long-term ownership trial is claimed for this page.
  • Manufacturer specifications may use different fuels, loads, test distances, temperatures, or operating modes. Cross-brand comparisons inherit those differences.
  • The listed price is a dated snapshot and may not equal the current delivered price.

Model-specific test matrix

Questions the measurements must answer.

01

Planned measurement

Continuous output & regulation

Pending

Can 12500 Tri Fuel hold useful loads without unacceptable voltage or frequency drift?

After manufacturer-specified warm-up, apply a correctly rated resistive load bank at 25%, 50%, 75%, and 100% of rated running output. Hold each step for a defined interval and continuously log watts, volts, frequency, and protective events.

Sustained wattsVoltage rangeFrequency rangeFaults or shutdowns
02

Planned measurement

Starting-load response

Pending

How much voltage and frequency sag occurs during a repeatable stepped starting load?

Use a controlled, instrumented starting-load fixture within published limits. Repeat the same step three times and record the lowest voltage, lowest frequency, recovery time, and whether protection trips.

Peak delivered wattsVoltage sagFrequency sagRecovery time
03

Planned measurement

Fuel use & runtime

Pending

How much usable energy is produced from a measured fuel quantity?

Outdoors at a controlled load, record the starting and ending fuel mass or volume using a safe approved method. Log elapsed time and delivered watt-hours without refueling during the valid measurement window.

Runtime at stated loadFuel per hourkWh per unit of fuelTest fuel and mode
04

Planned measurement

Sound profile

Pending

How loud is the unit under repeatable operating loads?

At an open outdoor site, measure A-weighted sound with a calibrated meter at 7 m / 23 ft on four sides at idle or eco, 25%, 50%, and 75% load. Publish distance, meter response, wind, surface, and ambient level.

dBA by side and loadAmbient dBADistanceOperating mode
05

Planned measurement

Cold & hot starting

Pending

How consistently does the unit start under documented conditions?

Follow the manual exactly and record three ambient-temperature starts plus three heat-soaked restarts. Report attempts, elapsed time, start method, battery state, and any intervention.

Attempts per startStart timeAmbient temperatureStart method

Controlled conditions

  • Record the exact model, serial number, firmware, sample source, and test date before any measurement.
  • Log ambient temperature, humidity, elevation, wind, surface, and background sound for every test block.
  • Record instrument model, range, accuracy, and most recent calibration or verification date.
  • Repeat timing, starting, and sound measurements three times when conditions allow; publish every valid run.
  • Keep original notes, load logs, meter exports, photos, and any excluded-run explanation with the result.

Required equipment class

  • Rated resistive or programmable load bank
  • True-RMS power, voltage, and frequency logger
  • Calibrated Class 1 or Class 2 sound-level meter
  • Approved fuel-measurement equipment and fire protection
  • Weather meter, timer, tachometer, and non-contact thermometer

Safety gate

Operate fuel-burning equipment outdoors only, far from occupied structures, openings, and ignition hazards, with working carbon-monoxide monitoring for personnel.

Testing is for qualified personnel using correctly rated load equipment and the manufacturer’s required grounding, bonding, clearance, and protective-device instructions.

Never connect a generator directly to building wiring or bypass overload, temperature, battery, GFCI, or carbon-monoxide shutdown protection.

Stop a run for unstable voltage or frequency, overheating, fuel or electrolyte leakage, abnormal sound, damaged wiring, or any manufacturer fault indication.

Badge rule: this product receives no “FMG Tested” label or score benefit until a real unit, instruments, conditions, valid runs, raw records, and limitations are documented under the public protocol.
