Power cuts are becoming more common across the UK due to winter storms, grid strain and extreme weather. A portable power station can keep essential devices running during an outage — but only if you choose the right size for your home.

This guide explains what a portable power station can realistically power during a UK power cut, how long common household items can run, and how to choose the right backup setup without overbuying or underbuying.

What household items can a portable power station run?

A correctly sized portable power station can power many everyday essentials during a UK power cut, including:

  • Wi-Fi router and broadband equipment
  • Mobile phones and tablets
  • LED lighting
  • Laptop or desktop computer
  • Television
  • Medical devices (model dependent)
  • Small fridge or freezer (time-limited)

Important: Runtime depends on the battery capacity of the power station and the total wattage of devices being used at the same time.

Typical UK power cut scenarios (realistic examples)

Short evening power cut (1–3 hours)

Most households want to keep:

  • Wi-Fi
  • Lighting
  • TV
  • Phones charged

A small to mid-size portable power station can comfortably handle this type of outage.

Overnight power cut

For longer outages, households often need:

  • Wi-Fi
  • Lighting
  • Phone charging
  • A fridge cycling on and off

A mid-capacity power station is usually required to avoid running out of power overnight.

Multi-day outage with solar recharging

During extended outages, adding solar panels allows:

  • Daytime recharging
  • Longer runtime for essentials
  • Reduced reliance on the grid

This setup is ideal for storm-related power cuts or rural UK locations.

What a portable power station usually cannot run

Being clear avoids disappointment. Most portable power stations are not designed to run:

  • Electric kettles
  • Electric showers
  • Large ovens or electric hobs
  • Whole-house heating systems

These appliances require very high power and are outside the scope of portable backup solutions.

How to choose the right size portable power station

The most common mistake is choosing a power station that is too small — or far larger than is actually needed. That’s why we built a UK-specific backup power calculator, based on real household usage rather than marketing claims.
