EcoFlow

Power stations from a 4 lb camping pack to a system that backs up a whole house.

EcoFlow was founded in 2017 by a group of battery engineers and is based in Shenzhen, China; its U.S. company is in San Francisco. Besides power stations it makes home batteries, solar panels, generators, power banks, and portable air conditioners and fridges, sold in more than 140 countries and regions. This page sorts its U.S. power stations by line, adds the solar panels and generators that recharge them, and covers the warranty, returns and support that come with them.

Power stations by line

EcoFlow sorts its power stations into lines by size, from packs you carry in one hand to systems wired into a house. The capacities are EcoFlow’s: from one unit by itself up to the most it reaches with extra batteries or linked units. Specs and prices come from our power station dataset, which doesn’t hold every model yet; a model we haven’t added says so.

TITAN

Whole-home backup

Capacity 5–30 kWh

An inverter and add-on batteries that can run central air and the rest of a house through an outage. It connects to the home’s wiring through EcoFlow’s Smart Home Panel 10, and with rooftop solar it stores daytime power for the evening. TITAN at EcoFlow (opens in a new tab)

Not added yet: TITAN 5000 Plus and TITAN 5000 Classic.

DELTA Pro Ultra

Whole-home backup

Capacity 6.1–180 kWh

A separate inverter and battery packs that run a whole house, 240 V appliances included, and grow by adding batteries or inverters. With EcoFlow’s Smart Home Panel 2 or 3 it takes over by itself when the grid fails, in under 20 ms. DELTA Pro Ultra at EcoFlow (opens in a new tab)

DELTA Pro

Home essentials

Capacity 3.6–48 kWh

EcoFlow’s largest single-box stations, on wheels, for keeping a home’s essential circuits running through an outage. Both take extra batteries, and both can be wired into the home through an EcoFlow Smart Home Panel. DELTA Pro at EcoFlow (opens in a new tab)

DELTA

Home, RV and work

Capacity 1–11 kWh

Mid-size stations that hold 1 to 3 kWh in one box, for outages at home, RV trips and work sites. In the DELTA 3 family, Max models hold 2 kWh and Ultra models 3 kWh, and the Plus versions of those two take extra batteries. DELTA at EcoFlow (opens in a new tab)

RIVER

Camping and short outages

Capacity 245–858 Wh

Small stations for camping, car trips and riding out a short outage. The RIVER 3 models also work as a UPS, switching a computer or router to battery in under 10 ms when the power goes out. RIVER at EcoFlow (opens in a new tab)

Not added yet: RIVER 3 and RIVER 3 Max Plus.

TRAIL DC

Tent camping, DC only

Capacity 192–288 Wh

EcoFlow’s smallest stations, 4 to 6 lb, with no AC outlets: power comes out through USB-C ports of up to 140 W, USB-A and, on the 300 models, a 12 V car socket. Made for tent camping and for charging laptops, cameras and lights. TRAIL DC at EcoFlow (opens in a new tab)

Solar panels and generators

EcoFlow sells three ways to recharge a station away from the wall: solar panels, solar generators that pair a station with panels, and generators that burn fuel. The scale compares the power each puts out: a panel’s rated watts, the panels in a solar generator’s box, and a generator’s running watts. A generator holds its figure while the fuel lasts; a panel reaches its rating only in strong sun, so over a day it makes much less, as our solar guide shows.

Solar Panels

Recharging from the sun

Rated power 28–400 W

Folding portable panels to stand beside a station, and rigid and flexible panels to mount on a roof, van or RV. Bifacial models also collect the light that reaches their back. Solar Panels at EcoFlow (opens in a new tab)

Not added yet: 400W Rigid Solar Panel, 100W Rigid Solar Panel and 28W Ultra-Light Solar Panel.

Solar Generators

A station with solar panels

Panels in the box 110 W–1.6 kW

What EcoFlow calls a solar generator is a power station sold together with EcoFlow solar panels, so it can recharge away from the grid; it burns no fuel. Each one is listed here, not again in the line of the station it’s built on. Solar Generators at EcoFlow (opens in a new tab)

Smart Generators

Recharging from fuel

Running power 1.8–3.2 kW

Generators made to recharge EcoFlow stations; the 4000 and 3000 run on gasoline or propane. Paired with a supported station, they start by themselves when its battery runs low and stop when it’s charged: the 4000 with the DELTA Pro 3, the 3000 with the DELTA 3, DELTA 3 Plus and DELTA 3 Ultra Plus. Smart Generators at EcoFlow (opens in a new tab)

Not added yet: Smart Generator.

Warranty

EcoFlow’s warranty starts on the day a unit is delivered and covers defects in materials and workmanship. It applies to units bought new from EcoFlow or an authorized seller and used in the United States. Repairs are by mail: for an approved claim in the contiguous U.S., EcoFlow sends a prepaid shipping label.

From the same policy. The 175W Rigid panel isn’t in it yet.

Where a term depends on registration, the longer one applies once you register the unit in the EcoFlow app or on EcoFlow’s warranty page (opens in a new tab).

Not covered: units from unauthorized sellers, the normal loss of battery capacity with age, and damage from misuse, water, accidents or third-party accessories. Keep your proof of purchase: a claim needs it, together with the serial number.

Returns and refunds

These terms are for orders from EcoFlow’s own store. A unit bought from a retailer may follow that retailer’s return policy instead, so check with the retailer.

  • Cancel within 24 hours of ordering for a full refund. Cancel later, before delivery, and EcoFlow keeps a transaction fee: 2.6% for card payments, 3.6% for PayPal.
  • Return within 30 days of delivery, complete and in the original packaging, for a refund or an exchange. After 30 days EcoFlow doesn’t take returns.
  • If you changed your mind, return shipping and the transaction fee come out of the refund. If the unit is faulty, you get a full refund or one free replacement.
  • Start the return online at EcoFlow’s returns center (opens in a new tab), and wait for the return authorization (RMA) and prepaid label before you ship. Lithium batteries have to be packed the way EcoFlow tells you.
  • The refund arrives within 14 business days of the unit reaching EcoFlow’s warehouse.

Shipping

  • Shipping is free within the contiguous United States.
  • EcoFlow’s store doesn’t ship to Alaska, Hawaii, Puerto Rico or other U.S. territories, or to P.O. boxes and military (APO/FPO/DPO) addresses.
  • Orders are processed within 3 to 5 business days, and EcoFlow estimates delivery at 7 to 10 business days. Nothing ships or arrives on weekends or public holidays.
  • If a unit arrives damaged, tell EcoFlow within 7 business days and keep the box and packing for the carrier’s claim.

Where to buy

Besides its online store (opens in a new tab), EcoFlow names these authorized online sellers in the United States: Amazon, Best Buy, Costco, eBay, The Home Depot, HSN, Lowe’s, Northern Tool + Equipment, REI, Sam’s Club, Target and Walmart, plus the specialist shops Shop Solar Kits, Wellbots and CampervanHQ. Certified dealers sell and install in Hawaii, Puerto Rico and the U.S. Virgin Islands.

Warning: The warranty covers only units bought from EcoFlow or an authorized seller. On a marketplace such as Amazon or eBay, check who the seller is before you buy.

Trading in an older unit

EcoFlow’s trade-in program (opens in a new tab) takes back eligible EcoFlow power stations for a gift card to its store, with the value quoted after an online evaluation. The old unit’s warranty ends as soon as you submit the trade-in.

Buying outside the United States

The models on this page are EcoFlow’s U.S. versions, with 120 V U.S. outlets. EcoFlow’s U.S. store ships only within the contiguous United States, and its U.S. service centers may decline a unit that has been taken abroad, leaving shipping, customs and taxes to you.

If you live elsewhere, buy from EcoFlow in your own region: it runs sites for Canada, Europe, the UK, Australia, Japan and some 40 other countries and regions, listed on its region page (opens in a new tab). Models, specs and prices there can differ from the ones here.

The EcoFlow app

EcoFlow power stations with Wi-Fi or Bluetooth connect to the EcoFlow app for iPhone and Android. It shows the charge level and the power going in and out, lets you change settings such as charging speed and outputs, sends low-battery alerts, and installs firmware updates.

On home systems it also sets the backup reserve, the share of the battery kept for outages, and time-of-use modes that charge from the grid when power is cheapest.

Batteries and recalls

Most EcoFlow stations, among them the RIVER 3 Plus, DELTA 3 Plus, DELTA Pro 3 and DELTA Pro Ultra X, use lithium iron phosphate (LFP) cells, which last thousands of charge cycles: EcoFlow rates the DELTA 3 Plus for 4,000 cycles before it drops to 80% of its capacity. The TRAIL DC models use NMC (nickel manganese cobalt) cells, which are lighter for the energy they hold. Each product above shows its battery type.

Warning: In October 2025 EcoFlow and the U.S. Consumer Product Safety Commission recalled about 25,000 DELTA Max 2000 units (model EFD310, serial numbers starting with DA), which can overheat and catch fire. The fix is a free firmware update through the EcoFlow app, to version 1.6.2.81 or later. No other model is part of the recall. If you’re buying a used DELTA Max 2000, make sure the update has been installed.

Details are on EcoFlow’s recall page (opens in a new tab) and in the CPSC notice (opens in a new tab).

EcoFlow terms on spec sheets

  • X-Stream is EcoFlow’s fast charging from a wall outlet. A DELTA 3 Plus, for example, charges from empty to full in 56 minutes at 1,500 W.
  • X-Boost lets a station run a heating appliance rated above its output, such as a kettle or a hair dryer, by lowering the voltage it gets. The station’s rated output stays the same, and EcoFlow’s manuals say X-Boost doesn’t suit devices with strict voltage needs. Size for the rated output, not the X-Boost figure.
  • UPS mode switches the devices plugged into a station to its battery when the grid fails. EcoFlow quotes under 10 ms for the RIVER 3 and DELTA 3 Plus, which it says is quick enough for desktop computers and NAS drives.
  • Smart Extra Battery is EcoFlow’s add-on battery: it plugs into a compatible station to add capacity.
  • XT60 and XT60i are the solar input plugs on most EcoFlow stations. EcoFlow panels end in MC4 plugs: the 400W Portable and NextGen 220W come with a cable to XT60 or XT60i, and the 100W Rigid comes without one.
  • Bifacial panels have cells on the back too, so they also turn light reflected from the ground into power. EcoFlow quotes up to 25% more for the NextGen 220W in the best conditions.
  • Smart Home Panel wires a DELTA Pro, DELTA Pro Ultra or TITAN into a home’s circuits, so it powers them in an outage and switches over by itself. It has to be installed before use.
  • Smart Generator is EcoFlow’s gasoline and propane generator. Paired with a supported station, it can start by itself when the battery runs low.
