Heads up: some links here pay us. If you buy through an EcoFlow or eufy link we may earn a commission, at no cost to you (that's Awin, in some countries). Amazon and other shop links pay us nothing right now. I haven't tested these products myself unless the page says so; the picks come from the specs and listings, and I'll tell you when I'm not sure.

$500-$800 (WINNER) - EcoFlow Delta 3
Plan on about $0.60 to $0.70 per watt-hour at list for a 1kWh LiFePO4 station, and treat anything much above $1 as a premium for size. The EcoFlow Delta 3 is the sweet spot: 1024Wh and 1800W for $699 at list, or $599 in the current sale. Under $250 you pay about $0.86 per watt-hour for a small unit. At 2kWh and up the price per watt-hour keeps falling, but only if you will use the capacity.

How This Was Researched
Prices were read from EcoFlow's US, French and Dutch stores on 2 October 2026, and specifications from EcoFlow's own spec sheets. Price per watt-hour is the listed price divided by rated capacity. We priced EcoFlow units because those are the ones we have verified end to end, so the tiers show how one maker prices a ladder of sizes, not a survey of every brand.
Frequently Asked Questions
At list price, about $0.60 to $0.70 per watt-hour for a 1kWh LiFePO4 station, falling toward $0.60 at 2kWh and rising above $0.85 for units under 300Wh. The four EcoFlow models in this guide run from $1.05 per watt-hour (River 3 Plus) to $0.59 (Delta 3 Max) at list. Sale prices lower those figures.
The discounts are real against the list price on EcoFlow's own store. The Delta 3 lists at $699 and sells for $599 in the Prime Day Fall Sale, which runs to October 5, 2026. EcoFlow discounts often, so list price is the better anchor. Treat a sale as a bonus, and check that the sale price is lower than the last one you saw.
Add up the wattage of what you will run and divide the watt-hours by it. A 100W load on 1024Wh runs for roughly ten hours before conversion losses, which reduce that somewhat. For a CPAP, a router and phones, 250Wh is usually enough for a night, depending on the machine. A fridge's draw varies, so 1kWh is a common starting point for an outage.
All four units here use LiFePO4 cells. EcoFlow publishes 3000 cycles to 80% capacity for the River 2 and River 3 Plus and 4000 for the Delta 3. For backup that you cycle a few times a year, any of them outlasts the product. Cycle life matters if you charge and discharge daily, for example on solar.
Not quite. EcoFlow's French and Dutch stores list the River 2 at EUR 199, the River 3 Plus at EUR 299, the Delta 3 at EUR 749 and the Delta 3 Max at EUR 1,299. The Delta 3 Max is far more expensive there than in the US sale. Compare against the store you will actually buy from.
