EcoFlow power stations compared: RIVER, DELTA and DELTA Pro (2026)
EcoFlow splits its US range into three families: RIVER for small, light units, DELTA for 1 to 3kWh home backup, and DELTA Pro for whole-home systems. Within DELTA alone there's now a Classic, a Max, a Max Plus, an Ultra and an Ultra Plus. This page compares the EcoFlow power stations we found on EcoFlow's US store and Amazon on November 9, 2026, with capacity, output, surge, weight, battery cycles, wall recharge time, solar input and expansion side by side. Every figure is EcoFlow's own; we haven't tested these units. The size calculator below works out what you'd actually need for an outage.

Before you buy
Decode the range.
RIVER models (245Wh to 768Wh) are for phones, a router, lights, a CPAP or a laptop, and the RIVER 3 Plus clips on an EB300 battery to reach 572Wh. DELTA 3 and DELTA 3 Classic are the 1kWh models; DELTA 3 Max and Max Plus the 2kWh ones; DELTA 3 Ultra and Ultra Plus the 3kWh ones. DELTA Pro 3 and DELTA Pro Ultra are 240V home systems, listed for scale and covered on our home backup page.
Size it on what you'd run.
A fridge through an outage wants the 1kWh class: the DELTA 3 gives 1,800W with a 3,600W surge by EcoFlow's figures. A fridge, furnace fan and lights for a day suits the 2kWh DELTA 3 Max or Max Plus. Long outages suit the DELTA 3 Ultra, which expands to 11kWh with DELTA Pro 3 extra batteries.
Max or Max Plus?
Both hold 2,048Wh. The Max Plus gives 3,000W against 2,400W, doubles the solar input to 1,000W and takes an extra battery (two, up to 10kWh, once EcoFlow releases its expansion adapter); the Max can't expand. Pay for the Plus only if you'll use the extra output or batteries.
Ultra or Ultra Plus?
The same 3,072Wh and 3,600W; the Ultra Plus takes 1,600W of solar against 800W. Only worth it with a big solar array.
Recharging.
EcoFlow's X-Stream wall charging is fast: a full DELTA 3 in 56 minutes and a RIVER 3 in an hour, by EcoFlow's figures; the 2kWh and 3kWh models quote time to 80% instead. All the RIVER and DELTA 3 models here have 120V outlets only.
What it will run, and for how long
Each figure runs that one thing on its own from the AC outlet, worked out with BLUETTI’s runtime formula: capacity × 90% usable × 85% inverter efficiency ÷ (the appliance’s average draw + about 10W the power station uses itself). A refrigerator or freezer is costed at its day-long average from Energy Star’s figures, not the compressor’s peak. Routers and phones last longer on the USB or DC ports, which skip the inverter. Treat every figure as an estimate and plan on the low end.
| Running just this | Average draw | Small (about 300Wh) | 1kWh class (1,024Wh) | 2kWh class (2,048Wh) |
|---|---|---|---|---|
| Refrigeratorneeds a pure sine wave inverter: check the spec | 34–84W | may not start it (a compressor can need about 2,600W for a moment) | 8.5 to 18 hours | 17 to 36 hours |
| Freezer (chest or upright)needs a pure sine wave inverter: check the spec | 23–71W | may not start it (a compressor can need about 2,600W for a moment) | 9.5 to 24 hours | 19 to 47 hours |
| CPAP (blower only: humidifier and heated tube off)needs a pure sine wave inverter: check the spec | 4–20W | 7.5 to 16 hours | 26 to 56 hours | 2 to 4 days |
| CPAP with heated humidifier (and heated tube)needs a pure sine wave inverter: check the spec | 21–67W | 3 to 7 hours | 10 to 25 hours | 20 to 51 hours |
| Gas furnace blower (1/3 to 1/2 HP) | 450–600W | may not start it (a compressor can need about 1,800W for a moment) | about 1.5 hours | 2.5 to 3.5 hours |
| Modem and Wi-Fi router | 10–18W | 8 to 11 hours | 28 to 39 hours | 2 to 3 days |
| Laptop (plugged in, in use) | 30–70W | 3 to 5.5 hours | 10 to 20 hours | 20 to 39 hours |
| LED light bulb (60W equivalent, each) | 7.5–10W | 11 to 13 hours | 39 to 45 hours | about 3 days |
| TV (32 to 65-inch LED) | 30–128W | 1.5 to 5.5 hours | 5.5 to 20 hours | 11 to 39 hours |
| Home oxygen concentratorneeds a pure sine wave inverter: check the spec | 275–325W | 0.5 to 1 hour | about 2.5 hours | 4.5 to 5.5 hours |
Method: BLUETTI — Elite 200 V2 (runtime formula: DoD 90%, η 85%, self-consumption about 10W) · BLUETTI — Elite 100 V2 (self-consumption about 10W) · EcoFlow — test runtime before an emergency (0.80–0.90 for AC; DC ports for routers and phones). Appliance figures from Energy Star’s product data, Champion’s and DTE Energy’s wattage charts and the device makers’ manuals; the runtime pages show the workings for each appliance.
What size do you need? Work it out
Tick what you would keep running and for how long. It uses typical figures for each appliance, allows for what the power station uses itself and leaves 10% of the battery unused, and shows a cautious figure for older or larger appliances alongside.
You need about 1,597Wh of battery (up to 2,136Wh if your appliances are older or larger), and 898W of output if everything runs at once.

Common questions
Which EcoFlow power station should I buy?
For most homes, the DELTA 3: 1,024Wh, 1,800W output and a 3,600W surge, a full wall charge in 56 minutes, and room for one extra battery up to 5kWh, by EcoFlow's figures. For a day of essentials, the DELTA 3 Max; for long outages, the DELTA 3 Ultra.
DELTA 3 or DELTA 3 Classic?
Same capacity, output and surge on EcoFlow's pages. The DELTA 3 takes an extra battery; the Classic doesn't. Buy the Classic only if it's cheaper and you'll never expand.
What's the difference between RIVER and DELTA?
RIVER models are small (245Wh to 768Wh here) and light enough to carry one-handed; they run phones, a router, lights and a CPAP. DELTA models start at 1kWh and are sized for a fridge and essentials through an outage.
Can an EcoFlow run 240V appliances?
Not the RIVER or DELTA 3 models listed here, which have 120V outlets only. The DELTA Pro 3 and DELTA Pro Ultra give 240V; see our home backup battery comparison.
Can an EcoFlow run a refrigerator?
From the 1kWh DELTA models up, if the output and surge cover your fridge. The calculator on this page and our fridge guide do the sums.
