A portable power station is a large rechargeable battery with normal UK plug sockets, USB ports and often a car socket. Unlike a petrol generator, it’s silent, produces no fumes and is safe to use indoors – which makes it the most practical way for most households to keep essential devices running in a power cut.

This guide explains how to choose one, and our pick of the best portable power stations for home emergencies.

What can a power station run – and for how long?

Capacity is measured in watt-hours (Wh). As a rough guide, divide the capacity by the power a device uses (in watts), then allow for about 15% lost in conversion. Typical running power:

Smartphone charge: about 10–15Wh per charge
Wi-Fi router: 10–15W
LED lamp: 5–10W
Laptop: 40–70W
CPAP machine: 30–60W (check your model)
Fridge-freezer: around 100–150W while running, but it cycles on and off – roughly 1–1.5kWh a day
TV: 50–150W

So a 1,000Wh power station could keep a router, phones and lamps going for a couple of days, or run a typical fridge-freezer for most of a day.

What to look for

Capacity (Wh): 250–300Wh for phones, lights and a router; around 1,000Wh if you want to run a fridge or medical equipment; 2,000Wh+ for whole-home backup.
Output (W): the maximum the inverter can supply at once. Make sure it’s higher than everything you want to run together – and check the “surge” rating for fridges.
LiFePO4 battery chemistry: lasts thousands of charge cycles and is safer and longer-lived than older lithium-ion types.
UK sockets: buy the UK version so you get three-pin sockets.
UPS / EPS mode: some models switch over automatically in a power cut – useful for medical devices, routers and freezers.
Solar charging: lets you recharge during a long outage with portable solar panels.

Power station or generator?

A petrol or diesel generator gives more power for the money, but it must never be run indoors, in a garage or near windows – the exhaust contains carbon monoxide, which kills. It also needs fuel storage and must only be connected to your home’s wiring by a qualified electrician using a changeover switch. For most homes, a power station is the safer and simpler choice.

Tips for using a power station safely

Keep it charged – top it up every three months.
Use it in a ventilated spot, away from heat and water.
Don’t exceed its rated output; plug high-power appliances in one at a time.
Never connect it to your home’s wiring yourself.
