How long will a Jackery Explorer 300 Plus run a diesel air heater? (US 120 V)
Yes, it runs it 5.0 h
Includes this load’s 100% duty cycle and the station’s 12 W idle draw — not a label-wattage guess.

0 – 300 W across the rails above
No start-up rail: this start lasts minutes rather than milliseconds, so it was checked against continuous output rather than against a surge rating.
Two numbers decide this, and readers use them interchangeably: watts are the ceiling on what the inverter holds at any instant, watt-hours are how much energy the battery holds. A machine can have plenty of one and not enough of the other.
The verdict is a calculation, not a lookup; the hours are a division, not the nameplate watt-hours. The working is in the evidence below.
Where those numbers come from
A blank is never left blank. A field we have found no figure for says so, and a field whose sources disagree — two documents, or one document with itself — says that instead of picking one.
What a diesel air heater demands
No surge rating covers this one, so the engine did not use one: the start-up load lasts 60 seconds rather than milliseconds, and a demand of that length is checked against CONTINUOUS output, where a load that long belongs. That check is the one in the panel above.
Start-up figure Manufacturer-stated
The start-up figure is published by the manufacturer for this device, so it describes the actual hardware rather than a category.
What the Jackery Explorer 300 Plus offers
The arithmetic: 288 Wh nameplate × 80% published capacity coefficient = 230.4 Wh
Jackery publishes the coefficients but not this figure, so it is computed rather than copied.
What the machine consumes just being switched on. It sits in the runtime denominator alongside the load.

If this is not the pairing
BLUETTI Elite 30 V2 (US 120 V) reaches the same conclusion on a diesel air heater at 600 W continuous, and it is $239. Cheaper is only cheaper when the answer is the same — this one is. See that pairing →
