Quick Answer

For most UK buyers, the EcoFlow DELTA 2 (£508) is the best portable power station. It delivers 1,024Wh of capacity, 1,800W of output (enough for a kettle or microwave), charges from 0 to 80% in under an hour, and doubles as a solar battery when connected to EcoFlow’s plug-in solar system. It is the most versatile unit on the market at a price that undercuts much of the competition.

If you need something lighter for camping, the EcoFlow RIVER 2 (£209, 3.5kg) is the pick. For serious whole-home backup, the EcoFlow DELTA Pro 3 (£2,799, 4kWh) handles everything from the fridge to the central heating pump.

What Is a Portable Power Station?

A portable power station is a large rechargeable battery with built-in AC outlets, USB ports, and DC outputs. Think of it as a silent, fume-free alternative to a petrol generator. You charge it from the mains, a car socket, or solar panels, then use it to power devices and appliances wherever you need them.

They have become popular for a range of uses: camping and caravanning, power cut backup, outdoor events, market trading, van life, and off-grid cabins. Unlike a generator, there is no noise, no fuel, no exhaust, and no ongoing maintenance. You charge it, take it where you need it, and plug things in.

The key specifications to understand are:

• Capacity (Wh): How much energy the battery stores. A 1,000Wh unit can run a 100W device for roughly 10 hours, or a 500W device for about 2 hours.
• Output (W): The maximum power it can deliver at once. A 1,800W output means you can run any appliance drawing up to 1,800W.
• Weight (kg): Ranges from 3.5kg for compact units to over 80kg for whole-home systems.
• Charging speed: How quickly the unit recharges. Some units reach 80% in under an hour from the mains.

EcoFlow Range Overview

EcoFlow is the dominant brand in the UK portable power station market, and for good reason. Their products are widely available, well-supported, and (uniquely) integrate with their plug-in solar system. This means a DELTA 2 or RIVER 2 can serve double duty: a solar battery in your home during the week, and a portable power station at the weekend.

No other brand offers this kind of flexibility, which is why EcoFlow features heavily in this guide.

Here is the full current range available in the UK:

Model	Capacity	Output	Weight	Price	Best For
RIVER 2	256Wh	300W	3.5kg	£209	Day trips, phone charging
RIVER 2 Pro	768Wh	800W	7.8kg	£499	Weekend camping, small appliances
DELTA 2	1,024Wh	1,800W	12kg	£508	All-round (camping + home backup)
DELTA 2 Max	2,048Wh	2,400W	23kg	£1,189	Extended off-grid, caravans
DELTA Pro 3	4,096Wh	3,600W	51.5kg	£2,799	Whole-home backup
DELTA Pro Ultra	6,144Wh	7,200W	84.8kg	£4,299	Whole-home, expandable to 30kWh

All models use LiFePO4 (lithium iron phosphate) battery chemistry, which offers longer cycle life and better safety than the older lithium-ion cells found in some competitors. EcoFlow rates their batteries for 3,000+ charge cycles before dropping to 80% capacity, which translates to roughly 10 years of daily use.

Best for Camping

Top pick: EcoFlow RIVER 2 (£209)

At 3.5kg, the RIVER 2 is light enough to carry comfortably alongside your other gear. Its 256Wh capacity covers a weekend of phone and tablet charging, LED lighting, and a portable speaker with room to spare.

For a sense of scale: 256Wh will charge a smartphone roughly 20 times, run an LED camping lantern for over 40 hours, or keep a 12V cool box running for about 8 hours. For a two-night trip, that is more than enough for most people.

Upgrade pick: EcoFlow RIVER 2 Pro (£499)

If you want to run small appliances (a coffee maker, a mini fan heater on a cool morning, or an electric cool box for a full week), the RIVER 2 Pro trebles the capacity to 768Wh and boosts output to 800W. At 7.8kg it is still manageable, though not something you would want to carry on a long hike.

Both units charge from a portable solar panel, which makes them especially practical for extended trips. A 100W or 160W panel laid out during the day will top up the battery for the evening. EcoFlow’s 100W Flexible Panel is a good pairing: lightweight, foldable, and easy to strap to a rucksack or lean against a tent.

Best for Home Backup

UK power cuts average around 45 minutes, and most people barely notice. But storms can cause outages lasting hours or even days, particularly in rural areas across Northern Ireland where overhead lines are exposed to Atlantic weather. If you have experienced a prolonged power cut, you already know the value of backup power.

Essentials backup: EcoFlow DELTA 2 (£508)

The DELTA 2’s 1,024Wh capacity and 1,800W output covers the essentials during a power cut. It will keep your fridge running (typically 100-150W), power your broadband router and a few lights, and charge phones and laptops. Expect 6 to 10 hours of runtime depending on what you connect. Its fast charging (0-80% in 50 minutes from the mains) means you can top it up quickly if you get advance warning of bad weather.

Whole-home backup: EcoFlow DELTA Pro 3 (£2,799)

For households that want to keep everything running (heating pump, cooking, washing machine, entertainment), the DELTA Pro 3 delivers 4,096Wh and 3,600W of output. That is enough to power most homes for a full day during an outage, longer if you manage consumption sensibly.

Maximum protection: EcoFlow DELTA Pro Ultra (£4,299)

The DELTA Pro Ultra starts at 6,144Wh and can be expanded up to 30kWh with additional battery modules. With 7,200W of output, it handles everything in a typical home simultaneously. This is the option for anyone who treats power resilience as a priority, not an afterthought. At this level, you are looking at multi-day whole-home backup, especially when paired with solar panels for daytime recharging.

Best for Caravans and Motorhomes

Caravan and motorhome owners often rely on noisy, smelly generators or expensive hook-up fees at campsites. A portable power station eliminates both problems.

Top pick: EcoFlow DELTA 2 (£508)

The DELTA 2 sits comfortably in a caravan storage locker and delivers enough power for a 12V compressor fridge, LED lighting, phone and laptop charging, a small TV, and a coffee maker. At 12kg it is easy enough to lift in and out, and 1,800W of output means it handles most common caravan appliances without complaint.

Extended trips: EcoFlow DELTA 2 Max (£1,189)

For longer trips away from hook-ups, or if you run higher-draw appliances (a hair dryer, a microwave, an electric heater), the DELTA 2 Max doubles the capacity to 2,048Wh and increases output to 2,400W. At 23kg it is heavier, but weight matters less in a vehicle than on foot.

Both units work brilliantly with a rooftop or portable solar panel. A 400W Rigid Panel propped against the side of your caravan during the day will substantially recharge the battery, giving you a self-sufficient setup that does not rely on campsites or generators.

Best for Market Traders and Outdoor Events

If you run a market stall, food stand, or outdoor event, reliable power is non-negotiable. Card readers, tills, lighting, blenders, coffee machines, and display screens all need to keep running throughout the day.

Standard market stall: EcoFlow DELTA 2 Max (£1,189)

The DELTA 2 Max’s 2,048Wh capacity and 2,400W output gives you a full day of power for a typical market setup: card reader (5W), tablet till (30W), LED strip lighting (20-50W), and a small appliance like a panini press or coffee grinder (800-1,200W). For lower-draw setups, it will comfortably last two consecutive market days on a single charge.

High-draw or all-day events: EcoFlow DELTA Pro 3 (£2,799)

For food vendors running commercial blenders, coffee machines, or heating elements throughout a busy event, the DELTA Pro 3’s 4,096Wh and 3,600W output provides the headroom and endurance to get through even the longest days. It is significantly quieter than any generator you might be replacing, and many event organisers now prefer or require silent power sources.

Solar Charging

Every EcoFlow portable power station has a solar input, which means you can recharge from portable solar panels wherever there is daylight. This is useful for camping, caravan trips, and extended off-grid use. But EcoFlow’s real advantage goes further than that.

EcoFlow’s PowerStream plug-in solar system uses DELTA and RIVER power stations as its battery component. This means the same unit that powers your camping trip also works as a solar battery at home, storing excess generation from your plug-in solar panels for use in the evening.

This dual-purpose design is unique to EcoFlow and is a genuine differentiator. Instead of buying a dedicated solar battery that sits on a shelf 365 days a year, you buy a portable power station that earns its keep at home and on the road. A DELTA 2 connected to a PowerStream system stores daytime solar for evening use, then disconnects in seconds when you want to take it camping.

For portable solar charging on trips, EcoFlow’s panel range includes options from 100W flexible panels (ideal for backpacking) to 400W rigid panels (best for caravans and base camps). A 200W panel in reasonable UK sunshine will recharge a RIVER 2 in about 2 hours or a DELTA 2 in 5 to 6 hours.

Alternatives to EcoFlow

EcoFlow is our top recommendation, but it is not the only option. Three other brands are worth knowing about.

Jackery is the other well-known name in portable power stations. Their Explorer range covers similar ground to EcoFlow’s lineup, and build quality is solid. The main drawback is that Jackery units do not integrate with any plug-in solar system, so they are purely standalone power stations.

Bluetti offers competitive capacity and pricing, particularly in the mid-range. Their AC200 series is popular for home backup use. Like Jackery, there is no plug-in solar integration.

Anker entered the market with the SOLIX range, offering good build quality and competitive prices. Their C1000 is a capable mid-range unit. Anker has a plug-in solar system (SOLIX), but it uses a dedicated battery rather than repurposing their portable power stations.

All three are viable options. We recommend EcoFlow for the dual-purpose solar integration, proven UK availability, fast charging speeds, and the breadth of the range from 256Wh to 30kWh. But if you have no interest in plug-in solar and simply want a standalone power station, Jackery and Bluetti are worth comparing.

How to Choose the Right Size

Choosing the right portable power station comes down to four questions.

1. What capacity do you need?

List the devices you want to power and estimate how long you will use them. Multiply each device’s wattage by the hours of use to get watt-hours (Wh).

Device	Typical Wattage	4 Hours Use	8 Hours Use
Smartphone charge	15W	60Wh	120Wh
Laptop charge	60W	240Wh	480Wh
LED camping light	5W	20Wh	40Wh
12V cool box	40W	160Wh	320Wh
Mini fridge	100W	400Wh	800Wh
Coffee maker	800W	n/a (10 min = ~130Wh)	n/a
Electric kettle	1,500W	n/a (5 min = ~125Wh)	n/a

Add up the watt-hours for your expected use and choose a unit with at least 20% more capacity than your total. Batteries are less efficient in cold weather, and real-world capacity is always slightly below the headline figure.

2. What output do you need?

Check the wattage of the highest-draw appliance you plan to use. If you want to run a kettle (1,500W), you need a unit with at least 1,500W output. The RIVER 2 at 300W handles USB devices and small electronics. The DELTA 2 at 1,800W handles most household appliances. The DELTA Pro 3 at 3,600W handles virtually everything.

3. How much weight can you manage?

If you are carrying it on foot, stay under 5kg (RIVER 2). If it is going in a car or caravan, 12-23kg is manageable. For home backup, weight is largely irrelevant since the unit stays in one place.

4. What is your budget?

Portable power stations range from £209 to £4,299 in EcoFlow’s lineup alone. For most people, the sweet spot is £200 to £600. Spending less than £200 usually means compromising on capacity, output, or build quality. Spending over £1,000 only makes sense for extended off-grid use or whole-home backup.

Our Recommendations

Here are our top picks by use case, with links to buy.

Best all-round: EcoFlow DELTA 2 (£508). The unit we would buy if we could only have one. Enough capacity for a weekend camping trip, enough output for household appliances, and doubles as a plug-in solar battery at home. Hard to beat at this price.

Best for lightweight camping: EcoFlow RIVER 2 (£209). At 3.5kg with 256Wh, it covers phone charging, lights, and small electronics for a weekend. The entry point to portable power.

Best for weekend camping with appliances: EcoFlow RIVER 2 Pro (£499). Treble the capacity of the RIVER 2 with enough output for a coffee maker or mini fan heater.

Best for caravans and motorhomes: EcoFlow DELTA 2 (£508) or DELTA 2 Max (£1,189) for extended trips. Pair with a solar panel for self-sufficient touring.

Best for market traders: EcoFlow DELTA 2 Max (£1,189). All-day power for a standard market stall setup.

Best for home backup (essentials): EcoFlow DELTA 2 (£508). Keeps fridge, router, lights, and devices running through a typical power cut.

Best for whole-home backup: EcoFlow DELTA Pro 3 (£2,799). Full-home coverage for a day or more, with solar recharging for extended outages.

Best for maximum resilience: EcoFlow DELTA Pro Ultra (£4,299). Expandable to 30kWh for multi-day whole-home backup. The closest thing to going fully off-grid without a permanent installation.
