Head-to-head test
EcoFlow DELTA Pro vs Anker SOLIX S5000
The extra money buys 1,424Wh, a real 240V outlet and a much longer cycle rating, and the S5000 still costs less per watt-hour, so the DELTA Pro only wins when the lower ticket is a hard ceiling.

Spec deltas
The DELTA Pro weighs 99 lb and the SOLIX S5000 weighs 97, and that is the last thing these two have in common. The S5000 holds 5,024Wh to the DELTA Pro's 3,600, outputs 4,500W to 3,600, and has a 240V split-phase outlet where the DELTA Pro's record shows none.
The DELTA Pro is the cheaper box at $1,899 against $2,500. It is not the cheaper battery. Divide price by capacity and the S5000 comes in at $0.50 per Wh against the DELTA Pro's $0.53, so the extra money buys slightly more than its share of capacity, and the 240V outlet and longer cycle rating come with it.
The DELTA Pro's real claim is history. It has months of overnight-outage duty on recordA3 and a reputation as a home-backup standardA1. The S5000 has a spec sheet and a rating labelB0. That's the trade, and for most buyers the spec sheet is too far ahead to ignore.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
That is the difference between backing up the 120V half of a house and backing up a well pump, an electric dryer circuit or a split-phase transfer inlet. The DELTA Pro's 3,600W is all 120V on our record. No amount of runtime turns a 120V box into one that can start a 240V pump.

Why it mattersAnyone with a 240V well pump, or an electrician quoting a transfer-switch inlet, should rule the DELTA Pro out on this alone.
solar input
In a multi-day outage that compounds. The S5000 ends the engine's blackout night with 2,625Wh in hand, enough for 1.6 more nights like it, and needs less sun to top back up. The DELTA Pro ends with 1,415Wh, 86% of a second night, and needs more. Short winter days are where that shows.
DELTA Pro solar input: 1,600W into 3,600WhSOLIX S5000 solar input: 3,000W into 5,024WhB58-Hour Blackout: the DELTA Pro has 1,415Wh left, the S5000 2,625Wh
Why it mattersBuyers planning for outages longer than a night should weight the solar ceiling as heavily as the capacity.
cost / lifetime kWh
The DELTA Pro's lower price doesn't survive the division: per lifetime kWh it costs nearly twice as much. The S5000's 6,000 is Anker's own ratingB12, so treat it as a claim, but the DELTA Pro would still trail even if the S5000 managed only 3,500 cycles, because each of its cycles moves 1,424Wh more.
DELTA Pro: 3,600Wh x 3,500 cycles = 12,600 kWh lifetime, $0.15 per lifetime kWhSOLIX S5000: 5,024Wh x 6,000 cycles = 30,144 kWh lifetime, $0.08 per lifetime kWhBoth carry a 5-year warranty
Why it mattersDaily solar users who'll run the battery hard should buy the S5000 even if the upfront price stings.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: The S5000 carries 1,424Wh more at nearly the same weight, and that shows up in every scenario that runs past one night.
continuous output
Same weight on the hand truck, very different amount of night. The S5000 has 4,270Wh usable to the DELTA Pro's 3,060 after the same 15% derate, which is the gap between a comfortable second evening and a nervous one.
The DELTA Pro still covers an ordinary outage with room to spare. The case for the S5000 starts on day two.
Lifetime Value
Selected because: The S5000 is rated for 30,144 kWh over its life to the DELTA Pro's 12,600 under the same 5-year warranty.
cost / lifetime kWh
The cheaper unit is the dearer one to own: $0.15 per lifetime kWh against $0.08. A bigger pack rated for more cycles multiplies twice in the S5000's favour.
At a cycle a day that's 16.4 rated years against 9.6. The warranties are both 5 years, so beyond that you're relying on the rating, and the S5000's is Anker's ownB12.
What the Specs Don't Tell You
Selected because: Fan noise ratings, UPS switchover class and cycle life all differ here, and the noise figures need careful reading.
rated cycles
The noise card is the one to read slowly. EcoFlow publishes 60dB for the DELTA Pro and Anker 30dB for the S5000 in quiet operation, two makers measuring different things, so the difference between them is not a gap you can count on hearing. What we can say is that DELTA Pro-line testing heard a high-pitched fan whine above 2,000WA4, though that source may describe a sibling model.
The UPS card favours the S5000 on paper: rated no worse than 10ms against the DELTA Pro's 20ms ceiling. Routers won't care; a fussy desktop power supply might.
Your Life, Your Pick
Selected because: The S5000 wins or ties every scenario, and the van-life row shows how close it comes to a load neither unit fully covers.
The S5000 takes or shares every row, and the engine gives it the CPAP row only on the makers' noise ratings. Anker's label puts the S5000 outside sleeping rooms anywayB7, so whichever you buy for a CPAP, plan on a cord through the wall rather than a box on the nightstand.
Van life is the row neither finishes. The S5000 falls 415Wh short after the 15% derate, the DELTA Pro 1,625Wh, so only one of them is close enough that a little sun closes the gap.

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
SOLIX S5000
The DELTA Pro finishes the weekend at 69% used with 960Wh in hand — one cold night or an extra device eats into that. The SOLIX S5000 finishes at 49% with 2,170Wh, real slack for the spontaneous stuff. If you camp in variable weather, that buffer is the difference between relaxing and watching the battery app.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
SOLIX S5000
Both survive the night. The SOLIX S5000 finishes at 39% used with 2,625Wh left — 1.6 more nights like it. The DELTA Pro finishes at 54% with 1,415Wh, 86% of a second night. If your outages tend to run past one evening, that difference is the whole argument between them.

LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
SOLIX S5000
A CPAP is about 40W for eight hours, so both of these cover the night several times over — capacity isn't the question here, and the percentages are a formality. What matters is the box next to your pillow, and the only published difference is a rating: the SOLIX S5000 is rated 30dB against the DELTA Pro's 60dB. Each is the maker's own published rating, and the makers do not measure the same way, some quoting a best case and some a figure under load, so neither number describes a 40W draw and the two are not really comparable. Treat them as a reason to look for hands-on reports before either one goes next to a bed, not as a difference you can count on hearing.

Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 97 lbs the SOLIX S5000 is the one you'll be glad you brought. Fan noise under load is worth a listen too — it's audible in the lulls between songs.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the DELTA Pro comes up 1,625Wh short (about 65% covered), the SOLIX S5000 415Wh (91%) (its nameplate 5,024Wh actually clears this — the flat 15% conversion allowance is what tips it under). Either gets you most of the way, so this is a scenario you plan around rather than one you should rule them out for.

Conclusion
October 9, 2026
Verdict: the SOLIX S5000
Buy the SOLIX S5000. The DELTA Pro costs $1,899 and the S5000 $2,500, and the $601 between them buys 1,424Wh more battery, 900W more continuous output, 240V split-phase through an L14-30R that the DELTA Pro doesn't offer at all, nearly twice the solar input and a 6,000-cycle rating against 3,500. Per watt-hour the S5000 is the cheaper of the two. The two weigh within 2 lb of each other, so you give up nothing to carry it. The DELTA Pro keeps a lower ticket, a 12V car outlet and a long field recordA1A3; the confidence stops at 7 because the S5000 is known only from Anker's documentationB0.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
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, DELTA Pro rates 3.7/5 (26th percentile of 20 Home Backup-class units), and SOLIX S5000 rates 4.6/5 (74th percentile of 20 Home Backup-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Weight Reality Check
Neither unit is grab-and-go. The SOLIX S5000 (97 lbs) is manageable solo but heavier than a large checked suitcase. The DELTA Pro (99 lbs) is the same story. The two are within 2 lb of each other, so weight is a wash here.
DELTA Pro: 60dB Published
60dB is about as loud as a normal conversation. The SOLIX S5000 is rated 30dB — lower, but published by a different maker measuring its own way, so the two figures are not a like-for-like gap. For most people, fan noise around 45dB and up is where sleep starts to suffer.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The SOLIX S5000 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The DELTA Pro is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Worth saying because the per-dollar framing can suggest otherwise: the DELTA Pro works out at 2.6 years of cover per $1,000 spent against the SOLIX S5000's 2, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The SOLIX S5000 is rated for 6,000 cycles vs 3,500. In real life: at daily use, that's 16.4 vs 9.6 years. At weekend use (twice a week), it's 58 vs 34 years. One caution reading years across different sizes: a cycle is 5,024Wh on the SOLIX S5000 and 3,600Wh on the DELTA Pro, so count lifetime energy — roughly 30,144 kWh against 12,600 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.
Full record above — the Test Desk pick is the SOLIX S5000.

Support
US-based support. Historically known for incredible no-hassle replacements, but recent reports describe AI-driven support agents giving generic responses and complex return logistics for heavy units (hazmat shipping). The Anker brand reputation is still strong, but SOLIX-specific support quality is trending down.

Unique strength
A very large consumer-electronics parent behind SOLIX, and InfiniPower, Anker's name for the design it credits for long cycle life.
Worth knowing
SOLIX support quality appears to have declined from Anker's historically strong level, firmware updates have removed features without warning, and the expansion ecosystem is smaller than EcoFlow's.
Analyst note
The DELTA Pro is the model EcoFlow's home-backup reputation was built on, with the largest community in the category behind it. Anker brings the stronger hardware to this pair, but its SOLIX support record is the weaker of the two right now, so buy from a retailer with a solid return window.

Both expand, but the SOLIX S5000's higher solar ceiling (3,000W vs 1,600W) gives it the stronger off-grid growth path — more panels can feed a bigger bank as it grows.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro
The DELTA Pro has long been treated as a home-backup standard, built for high-draw appliances and expansionA1, and one long-term account describes it carrying essentials through multiple overnight outages over monthsA3. Line-wide reports describe wheels and a telescoping handle that work on smooth floors and struggle on rough groundA2, and a high-pitched fan whine under heavy loadsA4. Our research flags that some coverage mixes the DELTA Pro with the DELTA Pro 3, so those two entries speak to the line's character rather than this exact modelA0.

Who Should Buy Which
Buy the DELTA Pro if you…
- →Your budget stops at the DELTA Pro's price and a 3,600Wh, 120V backup covers what you actually run in an outage.
- →You run a 12V fridge or other car-socket gear straight off the unit; the S5000 has no 12V car outletB15.
- →You'd rather own the unit with months of overnight-outage duty on recordA3 than one known only from its spec sheet.
Buy the SOLIX S5000 if you…
- →Your house has a 240V well pump or your electrician is fitting an L14-30 transfer inlet.
- →Your outages run past one night and you'll be refilling from panels between them.
- →You'll cycle it daily off solar and want the longer rating and the lower cost per lifetime kWh working for you.
If neither fits
If you only need the fridge and router through a short outage, both are more battery than you'll use. A smaller portable station you can carry up the basement stairs will do that job for far less.
The Bottom Line
Two boxes that weigh the same, and one of them holds 1,424Wh more, speaks 240V and is rated for 6,000 cycles to 3,500, at a lower cost per watt-hour. The DELTA Pro's record is real, but it is a record for a smaller, 120V-only machine.
If the price gap is money you have, spend it. The S5000 is the one you'll still be glad you bought on the third day of an outage.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Should I buy the EcoFlow DELTA Pro or the Anker SOLIX S5000?
The S5000, unless the DELTA Pro's lower price is a hard limit. For the gap you get 1,424Wh more, a 240V split-phase outlet, 3,000W of solar input to 1,600W and a 6,000-cycle rating to 3,500, at a lower cost per watt-hour and nearly the same weight.
Can the EcoFlow DELTA Pro power 240V appliances?
Not on its own, according to our record, which shows no 240V outlet. The S5000 has an L14-30R carrying 240V split-phase at up to 4,500W. If a well pump or dryer circuit is on your list, that settles it.
Is the SOLIX S5000 quieter than the DELTA Pro?
The ratings can't tell you. Anker quotes 30dB in quiet operation and EcoFlow publishes 60dB, and the two makers don't measure the same way. Anker's label also keeps the S5000 out of sleeping rooms, so neither belongs beside a bed.
Which is easier to move, the DELTA Pro or the SOLIX S5000?
Call it even: 99 lb against 97, so weight doesn't separate them. The S5000 rolls on wheels with a pull rod and has a foot step for tipping it back onto them. Neither is a one-person lift into a car.
