Phones, medical devices and lights matter first in a cut. Bigger kit helps some homes — and kills people when used wrongly indoors.
Power banks (best first step)
- Keep one charged power bank per adult phone, plus a cable.
- Recharge after every use and check charge every few months.
- A bank will not run a kettle, heater or fridge.

What usually stops in a cut
Power Cut 105 notes that gas boilers, many hobs, internet and cordless phones may not work without electricity. Plan light, heat and cooking without assuming the boiler will fire.
Generators and engine kit
- Never run a petrol or diesel generator indoors, in a garage, or near open windows — carbon monoxide is colourless and deadly (HSE).
- Site outdoors, dry, away from doors and vents; use outdoor-rated extension leads; do not overload.
- Check local rules on noise and landlord or lease conditions — many flats cannot use generators.
Inverters and car power
- A car inverter can trickle-charge phones with the engine running outdoors and the vehicle ventilated. Never run a car in a closed garage.
- Match wattage to the device; heating appliances need far more than phone chargers.
