EcoFlow

EcoFlow is a maker of portable power stations, backup power for the home and related accessories, sold in the UK through its own online store at uk.ecoflow.com. The company states it serves more than six million users across 140+ countries and regions, and that it holds 1129 patents¹. For a UK household preparing for power cuts, storms and other interruptions, its products sit in the backup power category: battery units you charge in advance and run your essentials from when the mains supply fails.

This page covers what EcoFlow makes for UK households, what its DELTA and RIVER ranges are designed for, and the practical things you need to know after buying: the warranty, how to reach support, how long delivery takes and how the returns policy works. If you are new to household preparedness generally, start with our guide to getting started and the section on backup power at home.

Who makes EcoFlow

EcoFlow is the trading name of ECOFLOW INC, a company that designs and manufactures battery power products. The maker's own UK site describes a business operating at a large scale: more than six million users worldwide, products sold into 140+ countries and regions, and a portfolio of 1129 patents¹. The company also states that, based on 2024 sales, EcoFlow ranked No. 1 globally among Smart Home Energy Storage Solution brands¹. That claim is the maker's own, based on its own sales figures, and is presented here as the company describes itself rather than as an independent ranking.

For a UK buyer, what matters more than the company's size is that it runs a dedicated UK storefront at uk.ecoflow.com, with UK delivery, UK returns handling and a support team you can contact on weekdays. The store lists its terms plainly on its product pages: Lifetime Support, Warranty Protection and Fast & Free Shipping³. The store also displays a verified customer rating of 4.73 stars from 921 reviews³, which gives a sense of how buyers rate the purchasing experience, though as with any store-run rating it reflects only customers who leave reviews.

EcoFlow's product range falls into a few clear families, and understanding the families is the quickest way to find the right kit for your household. The two main power station ranges are DELTA, the larger units aimed at home backup, and RIVER, the smaller portable units aimed at days out, camping and short interruptions. Around them sit accessories and a generator, which we cover below.

What EcoFlow makes for UK households

For a UK household thinking about emergencies, EcoFlow's products answer three practical needs: keeping lights and devices running when the power goes, keeping a bag or box of ready kit that works without the mains, and in some setups helping with heating and cooking arrangements when the mains supply is interrupted. Our emergency kit guide explains what a household should keep ready overall; the sections below set out where EcoFlow's products fit.

The core product for most households is the power station: a large battery with sockets on the front. You charge it from the mains while the supply is working, and when a power cut comes you plug your essentials into it. How long it runs them depends on the size of the battery and what you plug in, which is why the range runs from small portable units to large home backup systems. Our power cuts guide explains what to do in the first minutes of an outage, and the backup power guide explains how to work out how much capacity your household actually needs before you choose a size.

Alongside the power stations, EcoFlow makes accessories for its products, and the store's product pages are where to check exactly what is included with each unit and what each accessory does, since the maker lists the contents and specifications for every product it sells there.

The DELTA range: home backup power

The DELTA range is EcoFlow's family of larger power stations, aimed at households that want to run more than a phone and a lamp during an interruption. The range includes several generations and sizes: the DELTA Pro, the DELTA Pro 3, the DELTA 3 in its standard, 1500, Classic and Max versions, the DELTA 2 in standard and Max versions, and the original DELTA in standard and Max versions. In each case the larger versions in the family hold more stored energy and can power bigger loads.

What distinguishes the DELTA family in the maker's specifications can be seen in its flagship model, the DELTA Pro Ultra. The maker lists a noise level of 30dB or less, an ingress protection rating of IP54, a high voltage tolerance of 290V, and an operating humidity range up to 90%⁴. In everyday terms: the unit is quiet enough to sit in a living space, the IP54 rating means it has a degree of protection against dust and water splashes, and the voltage tolerance matters because the electricity supply at your sockets is not perfectly steady, and a unit that tolerates a wide voltage range is less likely to be troubled by it. When comparing any DELTA model, check these same specification lines on the EcoFlow site for the specific version you are considering, because they vary between models.

A DELTA class unit is the right family to look at if your priority is keeping a fridge or freezer cold, running a home office through a working day, or keeping heating controls and internet equipment alive during a longer outage. It is also the family to consider if you want a unit that can be part of a longer term setup rather than something carried to the car. For the fuller picture of sizing a home backup unit, including how to add up what your household actually uses, see the backup power guide.

The RIVER range: portable power for shorter interruptions

The RIVER range is the smaller, lighter family, aimed at portability and shorter use. The current models are the RIVER 3 in standard and Plus versions and the RIVER 2 in standard and Max versions. These are units you can carry to another room, put in the car, or take camping, and they suit households whose main worry is a few hours without power rather than a day or more.

The maker's specifications for the RIVER 2 show what to look for across the family. The battery is rated to retain 80%+ capacity after 3000 cycles², which means the maker states the battery will still hold at least four fifths of its original charge after three thousand full charge and discharge cycles, a figure that matters because a power station's battery is the part that ages. The charging temperature range is 0°C to 45°C²: the unit charges within that range, so in a cold shed in winter or a hot car in summer, charging may be affected. The box contents are listed by the maker as the RIVER 2 unit itself, an AC charging cable and a quick start guide², so check the equivalent list for whichever model you are considering to see what else you may need to buy separately, such as a solar panel.

The RIVER 2 also carries a stated 5 year warranty², which is worth noting when comparing within the range, and we return to warranty cover below. For guidance on what a small power station can realistically run, and for how it fits alongside torches and lighting, see our guides on backup power and emergency lighting.

The Smart Generator and accessories

EcoFlow also makes a dual fuel generator, the Smart Generator (Dual Fuel), which sits alongside the battery units rather than replacing them. A generator produces power from fuel rather than storing it, which makes it a complement to a battery: the battery covers the first hours of an outage silently and indoors, and a generator can recharge the battery or run heavier loads over a longer interruption. If you are considering a generator of any kind, read the safety sections of our heating and cooking guide and home emergencies guide first, because generators must never be run indoors: their exhaust contains carbon monoxide, which kills. Follow the maker's own instructions for siting, ventilation and fuel handling, and the fire and rescue service advice on any fuel burning equipment.

Check the EcoFlow site for the accessory list that matches your model, because the right cable or charger affects how quickly you can recharge and from what. The maker's own product pages are the reliable place to confirm what a given unit comes with and what can be added to it.

Warranty cover on EcoFlow products

EcoFlow states that all products are covered by a comprehensive warranty service¹, and the UK store lists Warranty Protection among its standard terms³. The length of cover is stated per product: the RIVER 2, for example, is listed with a 5 year warranty². That means the place to confirm the warranty on the exact model you are buying is that model's own page on the EcoFlow site, where the maker states the terms.

Two practical points are worth holding on to. First, the warranty is described as applying to all products, not only those bought from the EcoFlow store, so a unit bought elsewhere should still carry the maker's warranty, though you will want to keep your proof of purchase from whichever retailer you used. Second, the length of cover varies by product: the STREAM series carries a 10-year warranty, while the DELTA carries 24 months and the 160W solar panel 12 months, so check the terms for your specific unit. When you contact support about a warranty matter, have your order details and the product's serial information to hand, as that is what the team will need to identify your unit and its cover.

Customer support: how and when to contact EcoFlow

EcoFlow's support team is available on weekdays. The maker does not publish fixed opening hours for UK customers on the pages reviewed here, so if your matter is time-sensitive, contact the team early in the working day and allow a day for a reply. For anything that concerns the safety of the electricity supply itself, such as a power cut or a damaged cable outside your home, use the 105 power cut service rather than waiting on a reply from the maker.

You can reach the team through the contact routes given on the EcoFlow website⁵. Support is the right route for questions about a product's specifications, warranty terms, troubleshooting a unit, or arranging a warranty repair. For anything that concerns the safety of the electricity supply itself, such as a power cut or a damaged cable outside your home, contact your electricity network operator using the 105 power cut service, which our power cuts guide covers, rather than the maker of your equipment.

Ordering from the UK store and delivery times

Orders placed on the EcoFlow UK site are, in the maker's words, typically processed and delivered within 3 to 7 business days¹. Business days exclude weekends, so in calendar terms a typical order arrives within about a week to a week and a half of placing it. The UK store also lists Fast & Free Shipping among its terms³. If you are buying with a particular storm season or event in mind, order with that window in mind rather than the day before.

The store also offers payment in instalments: the maker states options including PayPal and Klarna, with up to 3 months at 0% interest, and notes that Klarna's Pay in 3 and Pay in 30 days are unregulated credit agreements, available to those aged 18 and over, UK residents only, and subject to status¹. Treat any credit agreement, regulated or not, as a financial commitment and check the terms before using it.

Returns: the 30 day window

EcoFlow states that customers can request a return within 30 days of receiving their product¹. The period starts when the product arrives with you, not when you place the order, which gives you the full 30 days to try the unit in your home. Note the maker's own wording on scope: the policy applies to orders placed on the EcoFlow UK site¹. If you bought your EcoFlow product from another retailer, your return rights are against that retailer under its own policy, and the maker's warranty continues to apply to the product itself.

If you are within the window and want to return a unit, contact EcoFlow support with your order details and they will advise on the process. Keep the original packaging until you are sure you are keeping the product, as returns typically need it.

Kit bought from other retailers

EcoFlow products are also sold through retailers other than the maker's own store. The maker's warranty and support apply to its products wherever they are bought, as above, but the store's own terms, including the 30 day return window, apply only to its own orders¹. Independent UK consumer advice on battery powered products, from the charity CAPT, is to make purchases from reputable retailers and manufacturers⁶. That advice is given in the context of products like e-bikes and e-scooters, whose lithium batteries carry fire risks if poorly made, and the same principle applies to any product with a large lithium battery: buy from a seller you can trace, and register your purchase so you can be contacted if a safety notice is ever issued.

When buying from any retailer, check which version of a product you are getting, because EcoFlow sells several versions of the same model name, such as the standard and Max versions within the DELTA and RIVER families, and the specifications differ between them. The maker's own product pages are the reference for what each version contains and specifies.

Where EcoFlow kit fits in your household plans

A power station is one part of a prepared household, not the whole of it. Our backup power guide explains how to choose and use one, including how to work out what your household needs to run and for how long. Around it, keep the basics covered: our emergency kit, water and food guides set out what to store and how to use it safely, and the staying informed guide covers keeping news and warnings reaching you when the usual routes are disrupted. Households that need extra help during outages, including older, disabled and medically dependent people, should also read our guide to extra help in an emergency, which includes signing up to your network operator's priority services register.

For heating and cooking during an interruption, remember that a power station runs electrical appliances but has limits on how much it can power at once: check what each model can run on the maker's product page before planning to use it with heating or cooking equipment. Our heating and cooking guide covers the options that work without mains power or gas, and the safety points that come with each.
