EcoFlow River 2 vs River 3: What Changed, and Is the River 2 Still Worth Buying?

Published October 22, 2026. Every figure on this page comes from EcoFlow’s own store pages (US and Canada), checked on October 22, 2026. This is a spec comparison, not a hands-on test, and runtime numbers are labeled arithmetic. Prices and stock change often, so confirm on EcoFlow’s page before you buy.

The River 2 and River 3 are EcoFlow’s smallest AC power stations: roughly 250 Wh, about 8 lb, and a 300 W inverter. On paper they look almost the same. The differences are in the details: faster USB-C, a quicker backup switchover, a flatter case, and a claimed efficiency gain on small loads. There’s also a US-specific wrinkle. As of October 22, 2026, the base River 3 isn’t listed on EcoFlow’s US store, while a River 2 model and the larger River 3 Plus are. This page lays out what changed and when the older River 2 still makes sense.

Quick answer

• Same size class, same AC limit. Both are rated 300 W continuous AC (600 W surge or X-Boost), both use LFP (LiFePO4) cells rated to 80% capacity after 3,000 cycles, and both accept up to 110 W of solar.
• What the River 3 adds: 100 W USB-C (up from 60 W), a 126 W car output (up from 100 W), a <20 ms switchover (River 2: <30 ms), an IP54-rated battery pack, and EcoFlow’s claim of up to double runtime on very small loads.
• What the River 2 has going for it: slightly faster AC charging input (360 W vs 320 W, both rated 0 to 100% in about an hour), and it’s the one you can still order new from EcoFlow’s US store, at $219 on October 22, 2026.
• In the US, the real choice is often River 2 vs River 3 Plus. The River 3 Plus ($299 on EcoFlow’s US store on October 22) doubles AC output to 600 W, adds a <10 ms UPS mode and 220 W solar input, and can add extra batteries up to 858 Wh.
• If your loads are phones, lights, a router, or a laptop, the River 2 does that job fine. If you want a small UPS for a desk, or plan to grow, look at the River 3 Plus.

River 2 vs River 3: spec table

River 2 figures are from EcoFlow Canada’s RIVER 2 page (the original 256 Wh listing) and EcoFlow US’s RIVER 2 (240) page. River 3 figures are from EcoFlow Canada’s RIVER 3 page, because the base River 3 has no US store page right now.

What actually changed from River 2 to River 3?

Faster USB-C and a stronger car port

The River 2’s single USB-C port tops out at 60 W. The River 3’s port is rated 100 W, which matters if you charge a larger laptop over USB-C. The 12 V car socket also goes from 100 W to 126 W, which gives a little more headroom for 12 V fridges and other DC gear. If you run a 12 V cooler, compare its rated draw to both figures.

Quicker switchover for backup use

Both units can sit plugged into the wall and pass power through to your devices, then switch to battery when the grid drops. EcoFlow lists the River 2 at under 30 ms and the River 3 at under 20 ms. Neither is a true online (zero-transfer) UPS. For a modem, router, or lamp, either number is usually fine. Some desktop PCs and sensitive gear can reboot on a slow switch, which is why EcoFlow pitches the River 3 Plus (<10 ms) for desks. If you’re weighing a power station against a traditional UPS, see our LiFePO4 vs NMC explainer for why the battery chemistry matters for years-long standby use.

Efficiency on small loads (a maker claim)

EcoFlow says the River 3’s GaN-based electronics deliver up to double runtime for appliances under 100 W. Its own footnote says that claim comes from lab tests with very low-wattage loads, such as a 3 W light or a Wi-Fi router. So the gain, if you see it, shows up on tiny loads left running for many hours, not on a 250 W kettle or a power tool. We haven’t measured this.

Same AC limit, same solar limit

The things that most often decide whether a small power station can do a job didn’t change. Both inverters are rated 300 W continuous, and both cap solar input at 110 W from an 11 to 30 V panel. A device that needs more than 300 W continuous won’t run normally on either. EcoFlow lists a 600 W X-Boost figure for both, but that isn’t the same as 600 W of continuous output. Capacity is close too: 245 Wh for the River 3 vs 256 Wh on the original River 2 listing.

A flatter case

The River 3 is about the same weight (7.8 lb vs 7.7 lb) but shorter, at 4.4 in tall vs 5.7 in. It fits more easily under a car seat or in a shelf cubby.

How long will each run my stuff? (arithmetic, not a test)

A rough way to estimate runtime is capacity in watt-hours divided by your device’s draw in watts. Real runtime is lower because the inverter and electronics use some energy, especially on AC. Treat these as upper-bound arithmetic.

If you’re on the current US River 2 (240) listing, use 240 Wh, which trims each line by a few percent. For CPAP, fridge, or freezer sizing in more detail, see our job guides linked at the bottom of this page.

Is the River 2 still worth buying in 2026?

For basic jobs, yes. Its AC output, solar input, and battery chemistry match the River 3, and on October 22, 2026, EcoFlow’s US store listed the RIVER 2 (240) at $219. It handles phone and laptop charging, LED lights, a router during an outage, and short camping trips.

A few things to know first:

• Check the capacity on the listing you’re buying. The original River 2 was listed at 256 Wh. The current US page is titled RIVER 2 (240), and says 240 Wh in its bullet points and 243 Wh in its spec table. We couldn’t find an EcoFlow note explaining the change, so check the label or ask EcoFlow support if a few watt-hours matter to you.
• 60 W USB-C is the biggest practical limit if your laptop wants 65 W or more over USB-C. You can still use the AC outlet and the laptop’s own charger.
• No expansion. Neither the River 2 nor the base River 3 spec list mentions an extra battery port. If you might need more capacity later, that points to the River 3 Plus.

River 2 vs River 3 Plus: the comparison most US buyers face

Since the base River 3 isn’t on EcoFlow’s US store right now, a US buyer choosing new from EcoFlow is often picking between the River 2 and the RIVER 3 Plus. Figures below are from EcoFlow’s US River 3 Plus page, checked October 22, 2026.

The River 3 Plus costs $80 more on that date and weighs about 2.7 lb more. In return it doubles the AC limit, doubles solar input, switches over faster, and can grow. EcoFlow also sells a RIVER 3 Max bundle (River 3 Plus plus the EB300 extra battery) listed at $499 on October 22.

Which one fits which job

• Phone, tablet, lights, and a router through a short outage: River 2 or River 3. Pick on price and availability.
• USB-C laptop over 60 W: River 3 or River 3 Plus (100 W USB-C).
• Desk UPS for a monitor, modem, and small PC: River 3 Plus. 600 W AC and a <10 ms switchover give more margin. Check your PC’s real draw.
• Camping with one 100 W panel: any of the three. All accept at least 110 W of solar.
• 12 V cooler on a long weekend: work out the arithmetic above for your cooler, and consider the River 3 Plus with an extra battery if the numbers come up short.
• Anything that draws over 300 W (coffee maker, microwave, hair dryer): not the River 2 or River 3. Most full-size versions of those draw more than the River 3 Plus’s 600 W rating, so check the label.

FAQ

Is the River 3 bigger than the River 2?

No. EcoFlow lists the River 3 at 245 Wh and the original River 2 at 256 Wh, so they’re essentially the same size class. The River 3 is flatter (4.4 in vs 5.7 in tall) and weighs about the same.

Can the River 2 or River 3 work as a UPS?

Both can pass power through and switch to battery during an outage: under 30 ms for the River 2 and under 20 ms for the River 3, per EcoFlow. That’s fine for most routers and lights. For PCs and sensitive gear, EcoFlow points to the River 3 Plus and its under-10 ms switchover.

Is the River 2 discontinued?

Not in the US as of October 22, 2026. EcoFlow’s US store listed the RIVER 2 (240) as available at $219. The base River 3 wasn’t listed on the US store that day, though EcoFlow Canada still had a River 3 page.

Do the River 2 and River 3 use the same solar panels?

Both accept up to 110 W of solar at 11 to 30 V, per EcoFlow, so a single 100 W or 110 W panel in that voltage range fits either one. Check the panel’s open-circuit voltage against the 30 V limit.
