How long will a Bluetti AC60 run a gas combi boiler?
About 4.9 hours — 4 h 53 min typically, from 4 h 35 min in the worst case to 5 h 10 min at best. That assumes a gas combi boiler pulling 85 W for 60% of the time (average 51 W), plus the station's 9 W AC mains socket overhead — 60 W in total out of 293 usable watt-hours.
The gas makes the heat, so a battery only has to run the fan, pump and controls. Most boilers are wired into a fused spur rather than a plug, and some will not light on a station’s ungrounded output — read the boiler guide before relying on it.
Before you rely on it
The battery is the easy part. Most boilers are wired into a fused spur with no plug, and some will not light on a station's floating output because they sense the flame through earth. The boiler guide explains both problems and who can fix them.
The numbers
| Setup | Average draw | Cautious | Typical | Best case |
|---|---|---|---|---|
| 1 × gas combi boiler, UK 230 V | 60 W | 4 h 35 min | 4 h 53 min | 5 h 10 min |
| 2 × gas combi boiler, UK 230 V | 111 W | 2 h 29 min | 2 h 38 min | 2 h 47 min |
| 1 × gas combi boiler, US 120 V | 60 W | 4 h 35 min | 4 h 53 min | 5 h 10 min |
- 0.6 nights of eight hours, or 0.2 days of continuous running.
- Usable energy: 293 Wh of the 403 Wh on the box, after chemistry, inverter losses and the reserve.
- To keep it going for a full 24 hours you would need about 1,981 Wh of rated capacity — 4.9× this station.
- Start-up: the gas combi boiler asks for 85 W at switch-on against this station's 1,200 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.

|---|---|---|
| The pack is two years old | 4 h 29 min | -8% |
| The pack is five years old | 3 h 55 min | -20% |
| It is −10 °C outside | 4 h 9 min | -15% |
| You run it flat, no reserve | 5 h 25 min | +11% |
| You keep 20% back | 4 h 20 min | -11% |
