EcoFlow DELTA 3 vs Anker SOLIX C800
The C800 now costs $50 more than the DELTA 3 for 256Wh less capacity and a surge ceiling that only reaches 1.33x its continuous rating, against the DELTA 3's full 2x — there's no longer a value case for the smaller unit, only a preference one.

Spec deltas
The Anker SOLIX C800 costs $599. The EcoFlow DELTA 3 costs $549 — $50 less for a battery that holds 256Wh more, an inverter rated for 1,800W instead of 1,200W, and a surge ceiling of 3,600W against 1,600W. Whatever reason existed to consider the C800 on price, it's gone: the more capable unit is also the cheaper one now.
The number that actually separates these two is surge headroom, not price. The DELTA 3's 3,600W surge is exactly double its 1,800W continuous rating; the C800's 1,600W surge is only 1.33x its 1,200W rating. That gap decides whether a fridge or window AC compressor's startup kick gets through, since compressors briefly draw 2-3x their running wattage on start.
The C800 isn't left with nothing. At 23.8 lbs it's 3.2 lbs lighter than the DELTA 3, and that's the one column where it still wins. Everywhere else on this page — noise, switchover speed, whether you can add capacity later — the DELTA 3 is simply the better machine for less money.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Fridge and AC compressors spike 2-3x their rated draw at startup, so the C800's 1,200W continuous rating doesn't guarantee it can start a 500-600W fridge — its 1,600W surge ceiling gets eaten by the kick before the compressor settles into a running draw. The DELTA 3's 3,600W ceiling still has margin left after the same hard start.
DELTA 3's surge rating is 3,600W against its 1,800W continuous outputSOLIX C800's surge rating is 1,600W against its 1,200W continuous output
Why it mattersAnyone planning to run a compressor fridge, window AC, or other motor load off either unit should size against the surge number, not the continuous one — and only the DELTA 3's surge number leaves room to spare.
cost / lifetime kWh
When the pricier unit also has the smaller battery, the weaker inverter, and no expansion path, there's no version of 'you're paying more for something' left to argue. The extra $50 buys the C800 less capacity and less capability, not more.
DELTA 3 costs $549 against the C800's $599DELTA 3's cost is $0.18 per lifetime kWh against the C800's $0.26
Why it mattersBuyers who were holding out for the C800 because it used to be the discount option should recheck that assumption before buying — the discount is gone, and so is the reason to take the smaller unit.
Capacity
Buy the C800 and outgrow 768Wh, and the only move is a second unit bought from scratch. The DELTA 3 starts 256Wh ahead and can keep growing from there with expansion batteries, at a lower price than the sealed alternative.
DELTA 3 supports EcoFlow expansion batteries; the C800 is fixed at 768Wh with no expansion pathDELTA 3 already holds 1,024Wh against the C800's 768Wh, a 256Wh head start
Why it mattersBuyers who aren't certain their power needs are done growing should treat the DELTA 3's expansion bay as the deciding feature, not a nice-to-have.
45dB is loud enough to notice from a nightstand; 30dB sits closer to a quiet room. Someone sleeping two feet from either unit will hear the noise difference long before they'd notice 37% versus 49% of a full tank.
DELTA 3 is rated 30dB against the C800's 45dB under loadCPAP Overnight needs 320Wh, using 37% of the DELTA 3's tank and 49% of the C800's
Why it mattersBuyers whose real use case is bedside power, CPAP or otherwise, should weight the noise spec over the scenario percentage the table shows.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: surgeRatio, noise, expansion, and ups all fire and are now the whole story since price no longer separates them.
Four things separate these units now, and none of them is price. Surge power: 3,600W against 1,600W, or 2x continuous output against 1.33x — the difference between a unit that shrugs off a compressor's startup kick and one that might not. UPS switchover: 10ms line-interactive against 20ms standby, twice the margin for anything that can't tolerate a gap. Noise: 30dB against 45dB under load. Expansion: one unit can add capacity later, the other can't.
None of these favor the C800. At $50 less, the DELTA 3 isn't trading capability for a lower price anymore — it's just the more capable unit, full stop.
Growth Path
Selected because: The DELTA 3's expansion path is the one true structural edge, independent of price.
solar input
The DELTA 3's expansion batteries are the one advantage that has nothing to do with today's prices. If 1,024Wh ever stops being enough, mid-trip or two years from now, you add a battery instead of buying a second power station. The C800 is a closed box: 768Wh is the ceiling, that's it.
That only matters if your needs are actually growing. A buyer certain that 768Wh permanently covers their use case gets nothing extra from a growth path they'll never use — but at $50 less than the sealed alternative, there's no real cost to keeping the option open.
Lifetime Value
Selected because: cheaperToOwn now also favors p1 — worth surfacing since it reverses the old thesis entirely.
cost / lifetime kWh
Run the numbers and the DELTA 3 is the cheaper unit to own, not just the cheaper unit to buy: $0.18 per lifetime kWh against the C800's $0.26, and $110 per warranty year against $120.
There's no lifetime-cost argument left for the C800 to fall back on. The unit with more capacity, a faster inverter, and an expansion path is also the cheaper one to run every kWh through.
Your Life, Your Pick
Selected because: CPAP and Tailgate are the two scenarios either unit wins outright, both to p1.
CPAP Overnight and Tailgate Party are the two scenarios either unit wins outright, and both go to the DELTA 3. On CPAP, both units handle the 320Wh load easily — the real reason to prefer the DELTA 3 there is its noise rating, not the extra headroom. Tailgate Party is a harder cutoff: the DELTA 3 covers it at 77% of its tank while the C800 needs 103% of its own, more than it actually holds.
Weekend Camping, the 8-Hour Blackout, and Van Life Daily are lost causes for both units — neither comes close to the 2,100Wh, 1,645Wh, or 4,685Wh those scenarios actually need. Don't read either unit's wins elsewhere as proof it scales to a multi-day trip.

Conclusion
July 26, 2026
Verdict: the DELTA 3
Take the DELTA 3. It's $549 against the C800's $599 — $50 less for 1,024Wh instead of 768Wh, a 3,600W surge ceiling against 1,600W, a 10ms UPS switchover against 20ms, and 30dB against 45dB under load. It also supports EcoFlow's expansion batteries; the C800 is sealed at 768Wh for good. Even the lifetime math favors the DELTA 3 now: $0.18 per lifetime kWh against the C800's $0.26, and $110 per warranty year against $120. The one place the C800 still wins is weight — 23.8 lbs against 27 — so if a 3.2-lb difference is what decides how you'll carry it, that's a real, if narrow, reason to take the smaller unit anyway. Otherwise, this isn't close.

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, DELTA 3 rates 4.3/5 (61st percentile of 24 Everyday-class units), and SOLIX C800 rates 4.1/5 (50th 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.
15dB Is the Difference Between Quiet and Noticeable
30dB against 45dB under load. The DELTA 3 sits close to a quiet room; the C800's rating is loud enough to notice from a nightstand. That matters most for CPAP or any bedside use.
One Unit Grows, One Doesn't
The DELTA 3 accepts EcoFlow expansion batteries; the C800 is sealed at 768Wh for good. Worth paying for only if your power needs are actually likely to grow — a fixed, modest load gets nothing from a growth path it never uses.
2x vs 1.33x — the Number That Actually Decides This
Continuous ratings look close (1,800W vs 1,200W), but surge tells the real story: the DELTA 3 carries double its own continuous rating in reserve, the C800 only a third more. Check this number before running anything with a compressor or motor.
Line-Interactive Cuts the Switchover in Half
10ms against 20ms — the DELTA 3's line-interactive design switches over twice as fast as the C800's standby UPS. For a desktop, NAS, or networking gear, that gap is the difference between a blip and a reboot.
Full record above — the Test Desk pick is the DELTA 3.

Analyst note
The SOLIX C800 is sealed at 768Wh, which is fine if that covers you. The DELTA 3 starts at 1,024Wh and can grow beyond it with EcoFlow expansion batteries — real headroom the SOLIX C800 doesn't have if your needs climb toward partial-home backup.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3
Field data on the standard DELTA 3 (not the Plus/Max/Ultra variants) is limited, but what exists is consistent: at loads under 200W the fans often stay off entirely, and even at 500-800W they're barely audible from three feet awayA1. That tracks with its 30dB spec rating.
UPS switchover held up in testing too — a power cut resulted in a handoff fast enough that routers didn't reset and CPAP therapy wasn't interrupted, though that specific test ran on a sibling model sharing the same 10ms spec, so treat it as directionally reliable rather than confirmed on this exact unitA2.
“At low loads (under 200W) the fans often stay completely off, making the Delta 3 effectively silent; under moderate load (500–800W) the fans are barely audible from three feet away.”

portablepowernerd.com · thesolarlab.com · outputreport.com
Anker SOLIX C800
The C800's most consistently praised trait is charge speed: reviewers clocked a full charge in 58 minutes on a 600W AC adapter, matching Anker's claim and beating rivals like the Jackery 700, which needs over two hoursB9. That speed shows up in load tests too — a 1,000W coffee maker ran a full 42 minutes without issue, and one test pushed a 1,500W space heater, well past its 1,200W rating, for 25 minutes before it throttledB3B8.
Under lighter loads it's genuinely quiet, with reviewers reporting zero fan noise below 500W and only a mild hum at max outputB7. Two honest catches: it ships with no IP weather rating, so reviewers recommend keeping it covered outdoorsB2, and it's repeatedly flagged as heavier than lighter rivals despite its compact footprintB4B12 — though at 27 lbs, the DELTA 3 it's being compared to here is heavier still.
“We dropped it from a tailgate (30 inches) onto gravel—only minor scuffing, no damage.”

Who Should Buy Which
Buy the DELTA 3 if you…
- →You need real surge headroom for a fridge, window AC, or other motor-driven load — the DELTA 3's 3,600W ceiling has margin the C800's 1,600W doesn't.
- →You want to keep the option to add capacity later instead of committing to 768Wh forever — and you'd rather pay $50 less to keep that option open.
Buy the SOLIX C800 if you…
- →You specifically need the lighter unit — at 23.8 lbs the C800 is 3.2 lbs lighter than the DELTA 3's 27, and that's the one column it still wins.
- →You're already invested in Anker's SOLIX ecosystem or specifically prefer it — because on capacity, price, surge, noise, and switchover speed, the DELTA 3 wins outright now.
If neither fits
If your real need is a two-night camping trip (about 2,100Wh) or an 8-hour blackout with a fridge running (about 1,645Wh), both units fall well short — they land between 189% and 322% of what's needed. Look at a larger-capacity unit before choosing between these two.
The Bottom Line
At $549 against the C800's $599, the DELTA 3 is now the cheaper unit and the more capable one: more capacity, a bigger surge ceiling, a faster UPS switchover, a quieter cabinet, and an expansion path the C800 doesn't have. The C800's one remaining edge is weight — 23.8 lbs against 27 — and that's a real reason to take it only if carrying it matters more than everything else on this page.
This used to be a premium-versus-budget decision. It isn't anymore. Take the DELTA 3.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
EcoFlow DELTA 3 vs Anker SOLIX C800 — which one should I buy?
Take the DELTA 3. At $549 it's $50 cheaper than the C800's $599, and it also carries more capacity (1,024Wh vs 768Wh), a bigger surge ceiling (3,600W vs 1,600W), and an expansion path the C800 doesn't have. There's no longer a price reason to pick the C800.
Is the Anker SOLIX C800 still cheaper than the DELTA 3?
No — prices have moved since this comparison was first priced out, and the C800 is now $599 against the DELTA 3's $549, making the DELTA 3 the cheaper unit by $50. Any case for the C800 that rested on a lower price no longer holds.
Can either of these actually start a fridge?
The DELTA 3 is the safer bet. Its 3,600W surge rating is exactly double its 1,800W continuous output, giving real margin for a compressor's 2-3x startup kick. The C800's 1,600W surge is only 1.33x its 1,200W continuous rating, leaving much less room once a motor load actually starts.
Which one is quieter?
The DELTA 3, rated at 30dB against the C800's 45dB under load — a 15dB gap that's noticeable from a nightstand or a CPAP setup. Reviewers separately noted the C800 stays quiet specifically under 500W loads, with noise increasing as it approaches its rated output.
Does the DELTA 3's expansion path actually matter for most buyers?
Only if your power needs might grow. If 768Wh comfortably covers everything you plan to run, the C800 is still a capable unit, just no longer a cheaper one. If you're unsure, the DELTA 3 now costs less and keeps the option open at the same time.
