Are power stations safe to keep at home? Fire risk explained

A power station from a known brand, bought from a UK seller and used as the manual says, is a low-risk thing to keep at home. The fires in the news mostly involve cheap e-bike and e-scooter batteries, damaged packs, or chargers that don't match the battery. Here is what lowers the risk further.
Why the battery type matters
Almost every power station we list uses (lithium iron phosphate) cells. LFP is much harder to push into "thermal runaway", the overheating chain reaction behind lithium fires, than the lithium-ion types in phones and older power stations, and it gives off less energy if it does fail. It isn't zero risk, which is why the habits below still matter. Each product page shows the battery type; where a maker doesn't say, we write "not published".
Five habits that keep it safe
- Buy from the maker's UK store or a big UK retailer. You get a product made for UK sockets, a UK warranty and Consumer Rights Act protection. Be wary of grey imports and no-name units with no UK address.
- Use the charger and cables it came with. Mismatched chargers are a common cause of battery fires.
- Give it air. Keep the vents clear, don't cover it with a blanket or put it in a cupboard while charging, and keep it away from heaters and direct sun.
- Stop using it if it is damaged. A swollen case, a strong smell, hissing or unusual heat means stop, unplug if safe to do so, move away and contact the maker. If it smokes or catches fire, get out and call 999.
- Check for recalls. Register your product with the maker, and search the government's product safety alerts and recalls list once in a while.
Is it safe to charge overnight or leave plugged in?
Power stations have a battery management system that stops charging when full, and many are designed to sit plugged in as a backup. Follow the maker's manual. If you'd rather not leave anything charging while you sleep, charge it in the day: it holds its charge for months.
Indoors is the safe place, unlike a generator
A power station gives off no fumes, so unlike a petrol generator it can be used indoors. Power station or generator?

Questions buyers ask before buying
It's a lot of money for something I'll hardly use.
Price it against what it protects: a freezer full of food, a working router when you work from home, a CPAP machine through the night. A 1 kWh station that covers fridge, router, lights and phones for about half a day starts at £419. It also earns its keep outside power cuts: camping, the garden or a van. Who gets value.
Power cuts hardly ever happen where I live.
Most are short. The ones that matter come with winter storms and can last a night or more, and they are hard to plan for. A station sits in a cupboard charged and ready, needs a top-up every few months, and doubles as a camping or garden battery the rest of the year.
Will it actually run my things?
That is the right question, and the box rarely answers it. Pick your appliances in What will it run? and you will only see stations with enough output and battery for them, with the hours each one lasts.
Aren't lithium batteries a fire risk?
Almost every current model uses LFP (lithium iron phosphate) cells, which are far more stable than the lithium-ion in older gadgets. Buy from the maker's UK store or a big UK retailer, keep the vents clear and charge it indoors. Fire risk explained.
Won't the battery be dead in a few years?
LFP stations are rated for 3,000 to 10,000 charge cycles. Used once a week, even 3,000 cycles is over 50 years, and five-year warranties are now common. How long they last.
I'm not technical. Is it complicated?
No wiring and no fuel. You charge it from a wall socket, then plug things into it like a normal socket. Many switch on by themselves when the mains drops. If weight worries you, filter by it: some 1 kWh models are about 11 kg and smaller ones under 6 kg.
