Best portable power stations for home power cuts

The UK government’s power-cut guidance starts with communication, light and warmth. A charged phone power bank, LED torch and existing bedding may cover a short interruption. None of these stations is a required part of basic preparedness.

Write down what must stay on, its measured watts and how many hours you need. Separate phone charging from continuous loads such as a router, optical network terminal (ONT) or fridge. A plug-in energy meter can reveal a fridge’s average use over a day; its motor may also need a brief starting surge well above that average.

Buy a larger system only when this list justifies it. Keeping one occupied room comfortable with clothing and bedding usually stretches a battery much further than running electric space heating. See the Home & workshop category for related household equipment.

Watt-hours (Wh) measure stored energy; watts (W) measure the rate at which an appliance uses it. The number on the box is not all available at a mains socket.

Independent reviewers measured 202.5Wh AC from a RIVER 3 at 270W, 910Wh from an Explorer 1000 v2 and 910Wh from a DELTA 3 Plus. These were separate tests of China/US editions, with different methods. They establish that conversion losses matter; they do not rank UK low-load endurance. We have not tested these products.

For a deliberately cautious illustration, assume 80% of nominal capacity reaches AC loads and allow 10–20W of inverter overhead. These are planning assumptions, not measured idle figures for every station; Jackery itself gives an 18W standby example.

• A continuous 20W essential load gives roughly 5–6.5 hours from the RIVER, 21–28.5 hours from the Jackery and 20.5–27 hours from the DELTA.
• A continuous 100W load gives about 1.6–1.8 hours, 7–8 hours and 7 hours, respectively.
• The calculation is nominal Wh × 0.8 ÷ (load W + overhead W). Cold, ageing, reserve settings, high loads and incomplete charging can reduce these figures.

Use direct USB-C for a compatible laptop where possible. Do not assume a station’s 12.6V vehicle output is interchangeable with a router’s regulated 12V input. Match the device specification and connector.

A 1500W heater could exhaust a 1kWh-class station in roughly half an hour after losses. A fridge may run much longer because its compressor cycles, but only a measured consumption figure and successful startup test justify a runtime plan.

All three selected offers are UK 230V/50Hz versions. North America commonly uses 120V/60Hz; Japan commonly uses 100V with regional frequency differences. Other countries use different sockets and electrical standards. Buy a locally supported version. A travel plug adapter does not convert voltage or frequency, and a station’s UK AC input is not automatically universal.

• RIVER 3: 300W normal pure-sine AC; USB-C up to 100W. Solar is 11–30V, 8A and 110W maximum through its XT60 input.
• Explorer 1000 v2: 1500W normal/3000W surge AC; USB-C up to 100W and 30W. Each DC8020 solar input accepts 16–60V, up to 10.5A and 200W; two together allow 400W. Follow Jackery’s matching-panel instructions.
• DELTA 3 Plus: 1800W normal/3600W surge AC; two USB-C outputs up to 140W each with suitable devices and cables. Each XT60i solar input accepts 11–60V, up to 15A and 500W. The vehicle and barrel DC outputs share a 126W total limit.

“600W” RIVER and higher DELTA X-Boost advertising describe special modes that can reduce output voltage for certain loads. Use the normal rating when choosing equipment. Surge ratings are brief allowances, not continuous capacity.

The selected RIVER and DELTA advertise around 10ms backup transfer; Jackery specifies 20ms. A device can still restart during transfer. Test your actual load by disconnecting incoming mains under safe conditions. These are not certified medical-backup recommendations; arrange critical-equipment continuity with its supplier.

Fast mains recharge claims assume suitable temperatures, settings and a healthy supply. Follow the manual’s storage and maintenance schedule, keep ventilation clear, and check charge before forecast disruption. These LiFePO4 models should not be charged below their specified minimum, generally 0°C. Portable solar charging is weather dependent and needs a separate compatibility check.

This is desk research checked on 29 October 2026, not hands-on testing. We prioritised clear regional manuals, LiFePO4 batteries, useful normal output and credible evidence of usable energy. The three tiers represent a small reserve, a larger fixed reserve and an optional expandable platform.

The exact Amazon UK pages were opened to verify ASIN, edition, new price and availability. Repeated owner themes informed handling and setup cautions; anonymous runtimes and merged variant ratings were not treated as measurements. The independent tests are credited to their publishers and limited to their tested editions.

Prices were £199, £499 and £699, respectively, before any later promotions or delivery changes. Solar panels, extra batteries and specialist cables are not included in these station-only recommendations.
