How long will an OUKITEL BP2000 run a gas furnace?
About 4.8 hours — 4 h 46 min typically, from 4 h 29 min in the worst case to 5 h 2 min at best. That assumes a gas furnace pulling 600 W for 50% of the time (average 300 W), plus the station's 13 W AC mains socket overhead — 313 W in total out of 1,488 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.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × gas furnace, UK 230 V | 313 W | 4 h 29 min | 4 h 46 min | 5 h 2 min |
| 2 × gas furnace, UK 230 V | 613 W | 2 h 17 min | 2 h 26 min | 2 h 34 min |
| 1 × gas furnace, US 120 V | 313 W | 4 h 29 min | 4 h 46 min | 5 h 2 min |
- 0.6 nights of eight hours, or 0.2 days of continuous running.
- Usable energy: 1,488 Wh of the 2,048 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 10,336 Wh of rated capacity — 5× this station.
- Start-up: the gas furnace asks for 1,500 W at switch-on against this station's 4,000 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.

What changes the answer
| If instead… | Typical runtime | Change |
|---|---|---|
| The pack is two years old | 4 h 22 min | -8% |
| The pack is five years old | 3 h 48 min | -20% |
| It is −10 °C outside | 4 h 2 min | -15% |
| You run it flat, no reserve | 5 h 17 min | +11% |
| You keep 20% back | 4 h 14 min | -11% |
