Head-to-head test
EcoFlow RIVER 3 MAX PLUS WIRELESS vs Anker SOLIX C800 Plus
The EcoFlow now costs $50 less than the Anker (649-599=50) and still holds 428Wh more, runs 15dB quieter, and switches over twice as fast - the only case left for the Anker is its 1,200W inverter, and now you'd pay extra for it.

Spec deltas
This pair's price order flipped, and it flipped in the EcoFlow's favor. The RIVER 3 MAX PLUS WIRELESS is $599; the SOLIX C800 Plus is $649. The unit that used to cost more now costs less, and it kept every other advantage it had - more capacity, less noise, a faster UPS.
That capacity gap is 1,196Wh against 768Wh, and it decides most of what these units get used for. A CPAP overnight, a remote workday, a tailgate: none of that draws anywhere near the EcoFlow's 600W inverter cap, so its extra 428Wh just shows up as more runtime, at the lower price.
The Anker's answer is still the appliance that needs real watts: a kettle, a hair dryer, a compressor motor with a hard start. Its 1,200W inverter and 1,600W surge get to loads the EcoFlow's 600W can't touch. That's a genuine reason to buy it - it's just no longer the cheap reason it used to be.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
cost / lifetime kWh
There used to be a real trade here - pay more for the EcoFlow's better economics, or pay less and accept the Anker's. That trade is gone. The cheaper sticker and the cheaper energy point the same direction now.
EcoFlow price $599 vs Anker price $649EcoFlow cost per lifetime kWh $0.17 vs Anker $0.28both carry a 5-year warranty
Why it mattersAnyone comparing these on price alone should stop - the unit that costs less to buy also costs less to run, so price no longer argues for the Anker at all.
continuous output
The Anker's extra inverter headroom only matters for one kind of load: a high single-draw appliance. None of the everyday scenarios this page tests are that load, so in practice the deciding spec is the 428Wh capacity gap, not the more impressive-looking wattage number.
EcoFlow capacity 1,196Wh vs Anker 768WhEcoFlow inverter 600W vs Anker 1,200WEcoFlow wins CPAP Overnight, Remote Workday, and Tailgate Party
Why it mattersUnless your use case genuinely involves a heavy single appliance, judge this pair on capacity - where the EcoFlow leads - not on the inverter spec that reads bigger on paper.
For anyone running the unit within a few feet of where they sleep or work, the noise gap and the faster UPS switchover mean the EcoFlow protects both your ears and your sensitive electronics, while the Anker's fan gets loud specifically under the fast-charging, high-load conditions of the exact scenarios where you'd be near it.
EcoFlow 30dB vs Anker 45dB (15dB gap)EcoFlow UPS switchover under 10ms vs Anker under 20msreviewers confirm the EcoFlow's low noise fits overnight useA2A3, while the Anker's fan grows noticeably present under sustained high loadB1
Why it mattersCPAP sleepers and home-office setups should treat noise, not price, as the deciding spec here - and now the quieter unit is also the cheaper one.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: the price flip is the headline of this rewrite - EcoFlow is now cheaper and lower cost-per-kWh both
cost / lifetime kWh
Owning either for its 3,000-cycle life costs $120 a year on the EcoFlow's warranty math against $130 on the Anker's - and that's before the sticker gap. At $599 the RIVER 3 MAX PLUS WIRELESS is $50 cheaper than the $649 SOLIX C800 Plus (649-599=50), so the unit with the lower lifetime cost per kilowatt-hour ($0.17 against $0.28) is now also the lower up-front cost. There's no trade-off left to negotiate.
That's new. This pair used to ask you to pay a premium for the EcoFlow's extra capacity; now it doesn't. The only dollar the Anker still has going for it is the one you'd spend on more output, not on cheaper ownership.
Your Life, Your Pick
Selected because: every scenario where the two differ still goes to EcoFlow, now at the lower price too
Every scenario where these two split goes to the EcoFlow: CPAP Overnight (320Wh needed, 31% of the EcoFlow's usable capacity against 49% of the Anker's), Remote Workday (910Wh, 90% against 139% - only the EcoFlow clears it), and Tailgate Party (670Wh, 66% against 103%, same story). None of those loads gets near the 600W the EcoFlow's inverter caps out at, so its capacity edge is pure, uncontested runtime.
Weekend Camping, an 8-Hour Blackout, and Van Life Daily beat both units outright: a weekend's 2,100Wh need runs at 207% of the EcoFlow's usable capacity and 322% of the Anker's, and Van Life Daily's 4,685Wh need hits 461% and 718%. Buying for those needs means stepping up a class, not choosing between these two.
What the Specs Don't Tell You
Selected because: noise, expansion, surge, and UPS all fire and split the same way as everything else
The flags split along the same line as everything else here. Noise and UPS speed favor the EcoFlow - 30dB against 45dB, and a sub-10ms switchover against sub-20ms. Expansion favors it too: it takes add-on batteries while the Anker is sealed at 768Wh for good.
Surge ratio is the one flag that still favors the Anker: a 1,600W surge on its 1,200W inverter starts motors the EcoFlow's 600W setup can't approach. That's the whole remaining case for paying more for the Anker now - everything else on this list points EcoFlow.
Growth Path
Selected because: expansion is real and no longer costs a premium to get
solar input
The Anker's ceiling hasn't moved: sealed at 768Wh, no expansion battery exists for it. The EcoFlow adds capacity beyond its 1,196Wh base. That was true before the price changed and it's still true now - the difference is that the unit with the growth path is also the cheaper one to buy today.
If 768Wh is genuinely all you'll ever need, the Anker's sealed design costs you nothing extra in use - except the $50 it now costs more to buy sealed. If you can picture needing more later, the EcoFlow gives you that room without a second unit, for less money up front.
PowerScore Breakdown
Selected because: explains the output-vs-capacity trade that's the one remaining case for the Anker
overall power score
The score gap - 2887 against 2199 - mostly reflects capacity: 1,196Wh against 768Wh. It doesn't erase the Anker's 1,200W inverter, still double the EcoFlow's 600W, a real advantage the aggregate score can undersell for anyone whose single heaviest load exceeds 600W.
What the score can't tell you is which of those two things you need. If your appliance list tops out under 600W, weight the score as written and take the EcoFlow. If you've got something that draws harder, discount the score and check the inverter number instead - now knowing the higher score also happens to be the cheaper purchase.

Conclusion
July 26, 2026
Verdict: the RIVER 3 MAX PLUS WIRELESS
Take the RIVER 3 MAX PLUS WIRELESS. At $599 it's now $50 cheaper than the $649 SOLIX C800 Plus (649-599=50), and it was already ahead on the specs that decide most real use: 1,196Wh against 768Wh (428Wh more), 30dB against 45dB (15dB quieter), and a sub-10ms UPS against sub-20ms (twice as fast). It even keeps the lower lifetime cost per kilowatt-hour, $0.17 against $0.28. The honest catch: its 600W inverter is still half the Anker's 1,200W, so any single load over that line - the exact job the Anker's 1,600W surge exists for - still needs the Anker. That used to be a real trade-off against a lower price; now it's the only reason left to pay $50 more for less capacity. Buy the EcoFlow unless your heaviest single appliance clears 600W.

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 MAX PLUS WIRELESS rates 3.4/5 (9th percentile of 24 Everyday-class units), and SOLIX C800 Plus rates 4.0/5 (39th percentile of 19 Compact-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
45dB vs 30dB: A Gap You Can Hear
The Anker's fan is audible under sustained load; the EcoFlow's 30dB largely isn't. For anything running near where you sleep or work, that's the difference between forgetting the unit is on and getting up to check it - and it's no longer the pricier unit that's quieter.
One Ceiling Is Fixed, One Isn't
The Anker is sealed at 768Wh - outgrow it and the only path is a second unit. The EcoFlow takes expansion batteries beyond its 1,196Wh base. That headroom used to cost a premium; now it comes with the cheaper unit.
Surge Power: The Anker's Remaining Case
A 1,600W surge on the Anker's 1,200W inverter starts motors the EcoFlow's 600W can't approach. This is the one spec that still points to the Anker - and now the one thing worth paying $50 more for, if it's actually central to your use.
Sub-10ms vs Sub-20ms Switchover
The EcoFlow's faster handoff matters for a desktop, NAS, or router that reads a longer gap as a power event. For a lamp or phone charger it's invisible, but for sensitive gear, the quicker catch is the safer one - and now the cheaper one.

Unique strength
Parent brand trust from Anker's consumer electronics dominance. InfiniPower technology for long cycle life. Strong $/Wh value in the mid-size and larger units — the S2000, F2600 and C1000 are among the better buys per watt-hour in the catalog.
Worth knowing
Anker brings the trust of its consumer-electronics business and InfiniPower cells built for long cycle life, plus one of the better-rated apps in the category. The catch: SOLIX-specific support is trending down from Anker's historically excellent standard, and firmware updates have quietly removed features.
Analyst note
EcoFlow is the deeper, faster-moving ecosystem with a couple of recent stumbles; Anker is the steadier consumer brand with slipping station-specific support. Neither brand risk changes this pair's verdict - that's decided by capacity, noise, and now price, not brand.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 3 MAX PLUS WIRELESS
Field reports on this exact RIVER 3 MAX PLUS WIRELESS configuration are thin - it's a very recent release, and coverage leans on press reviews and sibling models rather than long-term owners, so treat this as early evidence, not a mature record. What's consistent: reviewers call the RIVER 3 line quiet enough for overnight use at its 30dB rating, explicitly contrasting it with cheaper units whose fans keep kicking on while you're trying to sleepA2A3A7A8. Recharge speed gets similar praise - empty to full from a wall outlet in around 2.3 hoursA1.
The practical wins owners flag are the fast UPS and the detachable power bank: sub-10ms switching so devices don't blink when the grid dropsA5, and a mini bank you can pocket without hauling the whole stationA6. The honest limit shows up too - one reviewer notes it won't run a hairdryer or microwave, though they add that's normal for a station this sizeA4, and the 'wireless' branding has led some buyers to expect a Qi charging pad that isn't thereA9.
“The RIVER 3 Max Plus (Wireless) can go from empty to full from mains in around 2.3 hours, which is very quick given its capacity.”

Anker SOLIX C800 Plus
The C800 Plus's field story is doing real work up to a ceiling, then hitting it. A reviewer ran a fridge and freezer for eight hours and it used about 10% of the packB6, and a simulated outage test found the unit cutting in instantly with no flicker on the monitorB4. Its 1,200W output clears loads the EcoFlow can't start, though even it taps out before kettles and some coffee makersB10.
Two notes cut the other way. The fan is audible under sustained high load: one review describes it as "unavoidable and quite present in a quiet house" above 80°F and around 1,030WB1, and other testers note it's noticeably present during fast charging more generallyB11. That's right where the 30dB EcoFlow pulls ahead. Multiple reviewers also flag 768Wh as an awkward middle ground - one calls it their lone concernB5, another notes it's meaningfully less than a same-price rival's capacityB12. Coverage here is press-and-enthusiast reviews, not long-term ownership, so weight it accordingly.

Who Should Buy Which
Buy the RIVER 3 MAX PLUS WIRELESS if you…
- →Anyone whose heaviest single load stays under 600W - laptops, a CPAP, lights, a compressor fridge - and wants the most runtime and the quietest fan for the money, now at the lower price too.
- →CPAP sleepers and home-office setups that need near-silence and a sub-10ms UPS so a grid blip doesn't reboot sensitive gear.
- →Buyers who can see their needs growing: the expansion path adds a battery instead of a second whole unit, and you're not paying a premium for that option anymore.
Buy the SOLIX C800 Plus if you…
- →The buyer with a genuine heat-making appliance on the list - a kettle, hair dryer, or some coffee makers - where the extra $50 buys the only inverter here with a real chance of starting it.
- →Anyone charging primarily from larger solar arrays, where the Anker's 300W input beats the EcoFlow's 200W.
- →Someone who specifically needs the higher 1,600W surge headroom for a demanding compressor motor and is willing to pay more for it now that it's no longer the cheaper unit.
If neither fits
Planning a full weekend of camping, an all-day blackout, or van-life daily use? Both come up short: a weekend's 2,100Wh need runs at 207% of the EcoFlow's usable capacity and 322% of the Anker's - neither comes close. Look at a 2,000Wh-class station instead of stretching either of these past its limit.
The Bottom Line
The RIVER 3 MAX PLUS WIRELESS is now the rare comparison where one unit is simply the better buy: cheaper at $599 against $649, and still ahead on capacity (1,196Wh to 768Wh), noise (30dB to 45dB), and UPS speed (sub-10ms to sub-20ms). The price gap that used to make this a real trade-off is gone, and it closed in the EcoFlow's favor.
The Anker still has one card: a 1,200W inverter with a 1,600W surge that starts loads the EcoFlow's 600W can't touch. If your heaviest single appliance clears that bar, pay the extra $50 for it. If it doesn't, take the EcoFlow and pocket the difference.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Which is cheaper, the EcoFlow RIVER 3 MAX PLUS WIRELESS or the Anker SOLIX C800 Plus?
The EcoFlow, now - $599 against the Anker's $649, a $50 gap (649-599=50). That's a change: this pair's price order used to run the other way. The EcoFlow still holds more capacity, runs quieter, and switches over faster, so there's no longer a price-versus-features trade-off in the Anker's favor.
Is the Anker SOLIX C800 Plus worth paying more for now?
Only if you need its 1,200W inverter or 1,600W surge to start a load over 600W - a kettle, hair dryer, or demanding compressor motor. For anything under that, you'd be paying $50 more for less capacity (768Wh against 1,196Wh), more fan noise (45dB against 30dB), and no expansion path.
Can the EcoFlow RIVER 3 MAX PLUS run a coffee maker or hair dryer?
No - its 600W inverter won't start most of them, and one reviewer notes it won't run a hairdryer or microwave. The Anker's 1,200W gets closer, though it taps out before kettles and some coffee makers too. If heat-making appliances are central to your use, neither is a clean fit, but the Anker has the better chance.
Which is quieter for CPAP or bedroom use?
The EcoFlow, clearly - 30dB against the Anker's 45dB, a 15dB gap reviewers on both sides confirm: the RIVER line is praised for near-silent overnight operation, while the Anker's fan is described as noticeably present under sustained load. Its sub-10ms UPS is a bonus for anything that can't tolerate a power blip.
Can I add more capacity later?
Only on the EcoFlow. It accepts expansion batteries so the same base unit grows with your needs, clearing the Anker's fixed ceiling. The SOLIX C800 Plus is sealed at 768Wh, and outgrowing it means buying a second station outright.
