Do you need one?
Most UK power cuts last a few hours, and for phones and lights power banks are cheaper and enough. A power station is worth it if you want to keep the fridge, Wi-Fi or an electric blanket going, if someone relies on medical equipment, or if you'd also use it for camping. Not sure?

The full ranking
EcoFlow DELTA 3 Classic
The best value 1kWh power station we found. It runs a fridge for most of a day, switches over in under 10ms so the Wi-Fi and fridge don't notice a power cut, and costs far less than rivals.
Skip it if: You need to carry it far. At 12kg it's a two-hands lift.
| Capacity | 1,024Wh (LiFePO4) |
| Continuous output | 1,800W |
| UPS switchover | ≤10ms |
| Weight | 12.1kg |
| Fridge-freezer (est.) | ~14.5 hours |
| Electric blanket (est.) | ~8.7 hours |
Jackery Explorer 2000 v2
Twice the energy of a 1kWh unit at a strong price per watt-hour. Enough for a fridge, lights and Wi-Fi through a full day and night.
Skip it if: Most short power cuts. A 1kWh unit is lighter and half the price.
| Capacity | 2,042Wh (LiFePO4) |
| Continuous output | 2,200W |
| UPS switchover | Not clearly published |
| Weight | Not published |
| Fridge-freezer (est.) | ~28.9 hours |
| Electric blanket (est.) | ~17.4 hours |
Jackery Explorer 1000 v2
The lightest 1kWh unit here, and well reviewed for being quiet. A great choice if it'll double as camping or campervan kit.
Skip it if: You need to run a microwave or kettle. 1,500W is the lowest output of the 1kWh group.
| Capacity | 1,070Wh (LiFePO4) |
| Continuous output | 1,500W |
| UPS switchover | ≤20ms |
| Weight | 10.8kg |
| Fridge-freezer (est.) | ~15.2 hours |
| Electric blanket (est.) | ~9.1 hours |
EcoFlow DELTA 3 Max
Home-backup class: 2kWh, high output and fast switchover. A strong pick if someone relies on medical equipment.
Skip it if: You'll ever move it far. It weighs over 20kg.
| Capacity | 2,048Wh (LiFePO4) |
| Continuous output | 2,400W |
| UPS switchover | ≤10ms |
| Weight | 20.3kg |
| Fridge-freezer (est.) | ~29 hours |
| Electric blanket (est.) | ~17.4 hours |
BLUETTI Elite 200 V2
The highest output of the 2kWh group (2,600W), so it can briefly handle a kettle or microwave.
Skip it if: Switchover time isn't clearly published, so for medical kit we'd choose the DELTA 3 Max.
| Capacity | 2,074Wh (LiFePO4) |
| Continuous output | 2,600W |
| UPS switchover | Not clearly published |
| Weight | Not published |
| Fridge-freezer (est.) | ~29.4 hours |
| Electric blanket (est.) | ~17.6 hours |
Anker SOLIX C1000 Gen 2
The most powerful 1kWh unit (2,000W), with very fast recharging (about 49 minutes) and 10ms switchover. Excellent, but you pay for it.
Skip it if: You're on a budget. The EcoFlow DELTA 3 Classic stores the same energy for £200 less.
| Capacity | 1,024Wh (LiFePO4) |
| Continuous output | 2,000W |
| UPS switchover | ≤10ms |
| Weight | 11.3kg |
| Fridge-freezer (est.) | ~14.5 hours |
| Electric blanket (est.) | ~8.7 hours |
EcoFlow DELTA 3 Plus
TechRadar's overall pick in its testing, with strong solar charging. A very capable unit, but in the UK the Classic version gives you the same capacity for less.
Skip it if: You don't need the extra solar input. Buy the DELTA 3 Classic instead.
| Capacity | 1,024Wh (LiFePO4) |
| Continuous output | 1,800W |
| UPS switchover | ≤10ms |
| Weight | 12.5kg |
| Fridge-freezer (est.) | ~14.5 hours |
| Electric blanket (est.) | ~8.7 hours |
BLUETTI Elite 100 V2
A solid 1kWh LiFePO4 unit at a mid-range price, a good alternative if the EcoFlow is out of stock.
Skip it if: Its UPS switchover time and weight aren't clearly published, so check before buying it for medical equipment.
| Capacity | 1,024Wh (LiFePO4) |
| Continuous output | 1,800W |
| UPS switchover | Not clearly published |
| Weight | Not published |
| Fridge-freezer (est.) | ~14.5 hours |
| Electric blanket (est.) | ~8.7 hours |
BLUETTI Elite 30 V2
The cheapest LiFePO4 power station worth buying. Keeps the Wi-Fi, phones, lamps and a CPAP going overnight, and lifts with one hand.
Skip it if: You want to run a fridge for more than a few hours.
| Capacity | 288Wh (LiFePO4) |
| Continuous output | 600W |
| UPS switchover | ≤10ms |
| Weight | 4.3kg |
| Fridge-freezer (est.) | ~4.1 hours |
| Electric blanket (est.) | ~2.4 hours |
EcoFlow RIVER 3 Plus
A compact, well-made small unit with fast switchover. Ideal for keeping the router and a lamp on through an evening power cut.
Skip it if: You want the most for your money. The BLUETTI Elite 30 V2 is £50 cheaper for the same capacity.
| Capacity | 286Wh (LiFePO4) |
| Continuous output | 600W |
| UPS switchover | ≤10ms |
| Weight | 4.2kg |
| Fridge-freezer (est.) | ~4.1 hours |
| Electric blanket (est.) | ~2.4 hours |
What to look for
- Capacity (Wh) decides how long it lasts. Output (W) decides what it can power. You need enough of both.
- LiFePO4 battery. Safer and longer-lasting (thousands of cycles) than older lithium types. Every model here uses it.
- UPS / fast switchover (10ms or less) if it's for a fridge, router or medical equipment, so nothing switches off when the power goes.
- UK plugs and a UK warranty. Buy from UK retailers or the brand's UK store.
- Weight. 1kWh units are 10–13kg, and 2kWh units 18kg+. Think about where it'll live and who'll lift it.
Frequently asked questions
What size power station do I need for a power cut?
About 300Wh keeps Wi-Fi, phones and lamps going through an evening, or a CPAP machine overnight. About 1,000Wh runs a fridge-freezer for most of a day or an electric blanket through the night. 2,000Wh or more suits long power cuts or medical equipment.
How long will a power station run a fridge?
A typical fridge-freezer averages around 60W over a day as the compressor cycles. A 1,000Wh power station gives roughly 14 hours, and a 2,000Wh unit about a day, after allowing 15% for losses. Use our power cut calculator for your own appliances.
What is UPS mode on a power station?
UPS (uninterruptible power supply) mode means the power station sits plugged into the mains, passing power through to your devices. If the power cuts out, it switches to battery in milliseconds, often under 10ms, so a fridge, router or CPAP machine keeps running without interruption.
Are power stations safe to use indoors?
Yes. Unlike petrol generators, battery power stations produce no fumes and are safe indoors. Keep them ventilated, on a hard surface, away from water and out of reach of small children. LiFePO4 batteries, used in every model here, are among the safest lithium chemistries.
How do I keep a power station ready for a power cut?
Charge it to full, store it somewhere cool and dry, and top it up every 3 months. Many owners leave it plugged in with UPS mode on, so it's always full and ready.
How we ranked these
Scores use our published formula: Value (35%, watt-hours per pound), Capacity (30%), Efficiency (20%: continuous output plus UPS switchover speed) and Portability (15%, weight). For power cuts we give full capacity marks at about 1,200Wh, because that covers a typical UK outage. Bigger units still win on capacity, but size alone doesn't buy the top spot. Units with unpublished weight get a neutral portability score. We haven't lab-tested these ourselves. Specs come from brand UK listings, UK retailers and independent reviews including TechRadar and T3. Spotted something out of date? Email hello@preparedhousehold.co.uk.
