EcoFlow RIVER 3 vs EcoFlow RIVER 3 230
Two nearly identical RIVER 3 units, 15 watt-hours and $10 apart — the standard 245Wh RIVER 3 gives you a bit more capacity for a bit more money, and that extra is cheaply priced.

Spec deltas
This is about as close as two power stations get: the EcoFlow RIVER 3 holds 245Wh for $209, the RIVER 3 230 holds 230Wh for $199. Same line, same everything else — 15 watt-hours and $10 apart.
Identical platform down the spec sheet: 300W output with a 600W surge, a 3,000-cycle LFP battery, 110W solar input, a 20ms UPS, sub-30dB operation, IP54 water resistance, and a 100W USB-C port — both at 7.8 lb. Whichever you pick, you get the same well-reviewed RIVER 3 hardwareA1A2.
So the entire decision is capacity versus price. The standard RIVER 3 gives 15Wh more for $10 more; the 230 saves the $10 for slightly less. There's no wrong answer — just a small nudge toward the size you need.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Stepping from the 230 to the standard RIVER 3 buys 15Wh for $10 — about $0.67 per watt-hour, cheaper than the roughly $0.85 you pay per watt-hour on either unit overall. The extra capacity is the best-priced watt-hours in the matchup.
the RIVER 3 is 245Wh for $209; the RIVER 3 230 is 230Wh for $199the $10 difference buys 15Wh$10 for 15Wh is about $0.67 per watt-hour, below either unit's roughly $0.85 rate
Why it mattersUnless you specifically want to save the $10, the standard RIVER 3 is the slightly smarter buy.
Same inverter, same ruggedness, same noise, same charging, same weight, same battery chemistry and lifespan — the RIVER 3 and RIVER 3 230 are one design at two capacitiesA2B2. Any reason to prefer one over the other that isn't 'how much capacity do I want' is imaginary.
both units share 300W output, 600W surge, IP54, a 20ms UPS, and sub-30dBA2B2both weigh 7.8 lb and use the same 3,000-cycle LFPthe only spec that differs is 15Wh of capacity
Why it mattersDon't overthink it: pick the capacity, ignore everything else, because everything else is the same.
At 230-245Wh, both are device-and-small-electronics units — enough for phones, cameras, a laptop, or a few hours of a fan, but neither covers a CPAP night (~320Wh), a full workday, or an outage. The 15Wh between them doesn't change that; it's noise against the shared ceiling.
both hold roughly 230-245Wha CPAP's roughly 320Wh overnight draw exceeds bothneither can run a full workday or a blackout
Why it mattersIf you need to actually run appliances or last a night, both are too small — size up rather than agonizing over these two.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The marginal-value math on the extra 15Wh is the whole decision.
cost / lifetime kWh
The only number that separates these two is price against capacity, and it slightly favors the bigger one. The standard RIVER 3's extra 15Wh costs $10 — about $0.67 per watt-hour, below the roughly $0.85 you pay per watt-hour on either unit. So the RIVER 3 gives you marginally better-priced capacity; the 230 gives you the lowest sticker.
Cost-to-own lands a hair apart too — $0.28 per lifetime kWh for the RIVER 3, $0.29 for the 230 — which is to say identical in any practical sense. This is not a value decision with a wrong answer; it's a $10 coin flip.
What the Specs Don't Tell You
Selected because: Every gotcha is identical — honest to say so — plus the shared IP54 caveat.
There are no differentiating gotchas here, which is the honest headline: both units share the same 20ms UPS, the same sub-30dB operation, and the same IP54 water- and dust-resistanceA2B2. Whatever one does, the other does identically, because they're the same hardware.
The IP54 rating is worth knowing for both: it's splash- and dust-resistant, not waterproof — fine for a drizzle or a dusty trail, not for submersion. Rugged enough to live in a bag or a truck bed; not a unit to leave out in a downpour.
Portability & Form Factor
Selected because: Same 7.8-lb, compact build; a wash worth stating plainly.
Portability is a wash by design: both weigh 7.8 lb and share the same compact, 30%-smaller-than-average footprint EcoFlow built the RIVER 3 line aroundA2. Either slips into a bag or a minivan cubby the same way.
The 15Wh of extra battery in the standard RIVER 3 adds no meaningful weight or size, so there's no portability penalty for choosing the bigger one. If you want the capacity, you're not carrying anything extra for it.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Neither unit
Neither unit covers a CPAP's roughly 320Wh overnight draw — both top out at 230-245Wh, so you'd be empty before morning. The 15Wh between them doesn't bridge that gap. For overnight CPAP use, both are too small; look at a 500Wh-plus unit regardless of which of these you preferred.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Neither unit
Neither runs a full laptop-and-monitor workday — both are sized to top up a laptop or run a phone and lights, not power a desk all day. If untethered work is the goal, these are the wrong tier; the 15Wh difference is irrelevant against a shared shortfall.

Tailgate Party
Game day power for the crew
Neither unit
A tailgate's cooler-and-speakers draw outruns both of these small units well before the party's over — 230-245Wh is a couple of phone-and-light hours, not an afternoon of audio. Between them the standard RIVER 3's 15Wh buys a few more minutes, but if a tailgate is the job, both are undersized.

Conclusion
July 13, 2026
Verdict: the EcoFlow RIVER 3
These are the same power station in two sizes. The EcoFlow RIVER 3 (245Wh, $209) and the RIVER 3 230 (230Wh, $199) share an identical platform — 300W output, 600W surge, 3,000-cycle LFP, 110W solar, a 20ms UPS, sub-30dB operation, IP54 water resistance, a 100W USB-C port, all at 7.8 lb. The only difference is 15Wh of capacity and $10. That $10 buys the extra 15Wh at about $0.67 per watt-hour — cheaper than either unit's own $0.85-0.87 rate — so stepping up to the standard RIVER 3 is the marginally better value. Get the RIVER 3 for a touch more capacity at a good marginal price; get the RIVER 3 230 to save the $10 if you want the smallest, cheapest option.

Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, RIVER 3 rates 4.4/5 (62nd percentile of 22 Personal-class units), and RIVER 3 230 rates 4.3/5 (57th percentile of 22 Personal-class units).

Who Should Buy Which
Buy the RIVER 3 if you…
- →You want a touch more capacity at a good marginal price — 15Wh more for $10, below the base per-Wh rate.
- →You want the mainline RIVER 3, the most-reviewed version of the platformA3.
- →The extra 15Wh might just cover your use where the 230 falls a hair short.
Buy the RIVER 3 230 if you…
- →You want the lowest price on the RIVER 3 platform — $199, $10 lessB3.
- →230Wh comfortably covers your devices, so you don't need the extra capacity.
- →You're buying several and the $10 each adds up.
If neither fits
Both are roughly 230-245Wh units — great for phones, cameras, a laptop, or a fan, but too small for a CPAP night (~320Wh), a full workday, or a blackout. If you need to run real loads or last overnight, step up to a RIVER 3 Plus or a 500Wh-plus unit; these are pocket-trip power, not backup.
The Bottom Line
These are one power station in two sizes, so don't overthink it. The standard RIVER 3 (245Wh, $209) is the slightly better value — its extra 15Wh is cheaply priced — and it's the mainline version reviewers recommend across the platformA3. Pick it if you want a touch more headroom.
The RIVER 3 230 (230Wh, $199) saves you $10 for a hair less capacity, on identical hardwareB2. If 230Wh covers your devices, it's an equally good buy. Either way you get the same quiet, IP54-rugged, well-reviewed RIVER 3 — the only real question is which size, and it's a $10 one.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
EcoFlow RIVER 3 vs RIVER 3 230 — what's the difference?
Just 15 watt-hours of capacity and $10. The standard RIVER 3 holds 245Wh for $209; the RIVER 3 230 holds 230Wh for $199. Everything else is identical — 300W output, 600W surge, IP54 ruggedness, a 20ms UPS, sub-30dB operation, 100W USB-C, and 7.8 lb. Get the RIVER 3 for slightly more capacity, or the 230 to save $10.
Is the standard RIVER 3 worth $10 more?
Marginally, yes — that $10 buys 15Wh, which works out to about $0.67 per watt-hour, cheaper than the roughly $0.85 you pay per watt-hour on either unit. So the extra capacity is well-priced. But if 230Wh covers your needs, the 230 is perfectly good and saves you the $10; there's no meaningful quality difference between them.
Are these big enough for a CPAP or a laptop overnight?
For a laptop, yes for a while; for a CPAP overnight, no. Both hold 230-245Wh, and a typical CPAP draws around 320Wh a night — more than either unit stores. They're sized for phones, cameras, a laptop top-up, or a few hours of small electronics. For overnight medical use, step up to a 500Wh-plus unit.
Are they waterproof?
No — both carry an IP54 rating, which is splash- and dust-resistant, not waterproof. That covers a drizzle, spray, or a dusty trail, but not submersion. Both are rugged enough to toss in a bag or a truck bed; just don't leave either out in a heavy downpour.
