How Long Will It Run

How long will a Jackery Explorer 600 Plus run a gas furnace?

About an hour — 1 h 29 min typically, from 1 h 24 min in the worst case to 1 h 35 min at best. That assumes a gas furnace pulling 600 W for 50% of the time (average 300 W), plus the station's 8 W AC mains socket overhead — 308 W in total out of 459 usable watt-hours.

The gas makes the heat, but the blower that pushes warm air through the ducts is a real motor with a real start-up surge — far more than a British combi boiler. Variable-speed (ECM) blowers usually draw less.

Before you rely on it

A furnace blower is a real motor with a start-up surge, and most furnaces are hard-wired with no plug. Some will not light on a station's floating output because they sense the flame through ground. The furnace guide explains all three problems and the safe way to connect one.

  • 0.2 nights of eight hours, or 0.06 days of continuous running.
  • Usable energy: 459 Wh of the 632 Wh on the box, after chemistry, inverter losses and the reserve.
  • To keep it going for a full 24 hours you would need about 10,171 Wh of rated capacity — 16.1× this station.
  • Start-up: the gas furnace asks for 1,500 W at switch-on against this station's 1,600 W peak — comfortable.

If this is for a power cut

Heating is what a battery does worst. In a power cut, warming people rather than rooms goes much further, and none of this needs a socket.

Without a power station: a 20,000 mAh power bank runs a USB heated throw for about 7 h 24 min. See the power bank numbers.

Hot water bottle and a vacuum flask. Boil water while you still can, keep it hot in a flask, and refill the bottle through the night.

Look for: A bottle made to BS 1970 in the UK, and a flask of a litre or more.

Hand warmers. Air-activated packs give hours of heat with no power at all, and a pocketful helps children and older relatives.

Look for: Long-duration packs, and the expiry date on bulk boxes.

Battery carbon monoxide alarm. Anything burning fuel indoors, a boiler relit after an outage included, can produce carbon monoxide you cannot see or smell.

Look for: A sealed long-life battery and EN 50291 certification in the UK (UL 2034 in the US).
