How to choose yours in four steps

A power station is a large battery with ordinary sockets. To get it right, you only need to know two figures: how much energy it stores and how much power it can deliver at once.

  1. List what you want to keep running

    Be realistic: in a power cut, what matters is usually the fridge, the router, the lights, the phones and, if you work from home, the laptop.

  2. Work out the watt-hours (Wh)

    This is the capacity: how long it lasts. Multiply each appliance's consumption by the hours you'll use it. Our calculator does it for you.

  3. Check the output power (W)

    This is what it can deliver at once. If you want to plug in a microwave or coffee machine, you need more than 1,200 W.

  4. Choose LiFePO4 and solar charging

    LiFePO4 batteries last thousands of cycles and are safer. A solar input lets you recharge if the outage lasts for days.

Rule of thumb: without the fridge, keeping the router, phones and lights on for 24 hours takes about 600 Wh. Add the fridge and you'll need around 2,000 Wh.

Compact: the basics for one night Up to 300 Wh

BLUETTI EB3A

The best compact station to start with

  • 268 WhCapacity
  • 600 WContinuous output
  • LiFePO4Battery type
  • 4 yearsWarranty

Keeps the router on all night, charges every phone in the house several times and powers LED lights. Light enough to take camping and cheap enough to keep in a cupboard just in case.

What we like

  • Very affordable entry price
  • Shoebox-sized
  • Can also be charged with a solar panel

Worth knowing

  • Won't run a fridge for more than a few hours
  • 600 W isn't enough for a coffee machine or microwave

Mid-size: remote work and a small fridge 700 to 800 Wh

BLUETTI AC70

The sensible middle ground

  • 768 WhCapacity
  • 1,000 WContinuous output
  • LiFePO4Battery type
  • 4 yearsWarranty

Enough for a working day with a laptop and router, or to keep the fridge going for around 12 hours. This is the range people buy most after a blackout because it covers the essentials without a big price tag.

What we like

  • Good balance of capacity and weight
  • Supports solar charging
  • Enough output for most household appliances

Worth knowing

  • Falls short for 24 h with a fridge and everything else
  • Battery can't be expanded

1 kWh: our pick for most homes Around 1,000 Wh

EcoFlow DELTA 3

The best all-rounder on the market

  • 1,024 WhCapacity
  • 1,800 WContinuous output
  • LiFePO4Battery type
  • < 10 msSwitchover

Our overall recommendation. It recharges very quickly from the mains, works as a UPS for your computer or router and accepts extra batteries if you need more runtime later on.

What we like

  • Fast charging from the mains
  • Works as a UPS: switchover is almost instant
  • Expandable with an extra battery

Worth knowing

  • Pricier than others of the same capacity
  • Heavy to carry far

Jackery Explorer 1000 v2

The lightest and simplest

  • 1,070 WhCapacity
  • 1,500 WContinuous output
  • LiFePO4Battery type
  • 10.8 kgWeight

If you'll move it around often, or want something anyone in the house can use, this is the one. One button, a clear display and a manageable weight for its capacity.

What we like

  • Lightest in its range
  • Very easy to use
  • Brand with a long track record

Worth knowing

  • Less output than its rivals
  • Fewer expansion options

BLUETTI Elite 100 V2

Best for use with solar panels

  • 1,024 WhCapacity
  • 1,800 WContinuous output
  • LiFePO4Battery type
  • Up to 1,000 WSolar input

Designed for recharging from the sun during a long outage or for use in a second home. It accepts a lot of solar input power and also works as a UPS.

What we like

  • Very high solar input
  • Solid build
  • Switchover to battery in 10 ms or less

Worth knowing

  • You need a separate panel to make the most of it
  • Smaller accessory ecosystem

2 kWh: the fridge and essentials for a full day Around 2,000 Wh

FOSSiBOT F2400

Most watt-hours per euro

  • 2,048 WhCapacity
  • 2,400 WContinuous output
  • LiFePO4Battery type
  • 24 h with a fridgeBest for

Hard to beat on price per unit of capacity. It keeps the fridge, router and lights running for a full day, with plenty of power for a microwave or coffee machine.

What we like

  • Best capacity-to-price ratio
  • 2,400 W output for almost any appliance
  • Great for caravans and campervans

Worth knowing

  • Heavy: not one to carry by hand
  • Younger brand than EcoFlow or Jackery

Expandable: serious backup for the whole house From 2 kWh to over 6 kWh

EcoFlow DELTA 2 Max

Grows with you

  • 2,048 WhCapacity
  • 2,400 WContinuous output
  • LiFePO4Battery type
  • 6,144 WhExpandable to

Start with 2 kWh and add up to two extra batteries. With the full system, a small 100 W fridge runs for around 60 hours. The choice for anyone who has lived through long outages and doesn't want to repeat the experience.

What we like

  • Up to 6 kWh with extra batteries
  • Pairs very well with a solar panel
  • 5-year warranty

Worth knowing

  • A big investment if you buy the full system
  • Takes up space: meant to stay in one place

Frequently asked questions

How long will a fridge run on a power station?

A modern fridge-freezer uses an average of 40 to 60 W over the day, because the compressor doesn't run all the time. With a 1,000 Wh station you can expect roughly 15 to 20 hours.

Is a power station better than a petrol generator?

Indoors, always a power station. It's silent, produces no fumes and works at the press of a button. A petrol generator only makes sense outdoors and for very high loads.

Can I leave it plugged in all the time?

Models with a UPS function are designed for it. For the rest, it's best to keep the charge between 60 and 80% and run a full cycle every few months.

Will the plugs work with my UK appliances?

The stations sold in Spain have Schuko (EU) sockets. UK appliances will need a UK-to-EU adapter, and it's best to use one rated for the appliance's power.

Can I take it on a plane?

No. Airlines limit batteries in hand luggage to around 100 Wh, and every model in this guide is well above that.
