Head-to-head test
Anker SOLIX S5000 vs BLUETTI Elite 400
At 85 lb the Elite 400 has already given up on portability, so it has to win on value, and it doesn't: the S5000 adds 1,184Wh, 240V and twice the rated cycles for 12 more pounds.

Spec deltas
Twelve pounds separate these two, and that's the number that frames everything else. The Elite 400 weighs 85 lb and rolls on a built-in trolleyB2B3; the S5000 weighs 97 lb and rolls on wheels with a pull rodA11. Neither goes to a campsite casually. Both are home-backup machines, and judged that way the S5000 is the stronger one.
It carries 5,024Wh against 3,840Wh, puts out 4,500W against 2,600W, and adds a 240V L14-30R and a TT-30R RV outlet the Elite 400 doesn't haveA3. It's rated for 6,000 cycles to the Elite's 3,000, which is why, despite costing $1,101 more, it comes out cheaper per lifetime kWh: 8 cents against 12.
The Elite 400 keeps one honest argument, the lower price. If your outage plan is 120V essentials and that gap decides whether you buy at all, it does the job. Otherwise, buy the S5000.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
cost / lifetime kWh
That flip pays out for the owner who cycles the unit, solar-charging it most days or shifting power off-peak. For someone who drains it a few times a year in storms, neither rating is ever reached: at weekly use even the Elite 400 is rated for 57.7 years.
S5000 rated 6,000 cycles; Elite 400 rated 3,000Cost per lifetime kWh: S5000 $0.08, Elite 400 $0.12Cost per Wh: Elite 400 $.36, S5000 $.50
Why it mattersDaily cyclers should treat the S5000 as the cheaper unit to own; storm-only owners should decide on outlets and capacity instead.
weight
At this weight neither unit gets carried anywhere, so the saving buys almost nothing, while the missing outlets cost a lot: no feeding a generator inlet, no plugging an RV shore cord straight in.
Elite 400 85 lb; S5000 97 lbElite 400 record: no 240V outlet, no 30A RV outletS5000: L14-30R at 240V up to 4,500W and TT-30R at 3,600WA3
Why it mattersIf you were leaning to the Elite 400 because it's lighter, that reason doesn't hold; pick it on price or not at all.
solar input
In a multi-day outage that's a morning's sun against a whole day's, provided you own enough panels. The catch to plan for: Anker rates the S5000's idle draw at 8.8W on 120VA16, about 211Wh a day just staying on (8.8 x 24), so switch the output off when nothing's plugged in.
S5000 solar input 3,000W across two inputsA5; Elite 400 1,000WS5000 5,024Wh; Elite 400 3,840WhS5000 idle draw 8.8W on 120V output, Anker internal testingA16
Why it mattersAnyone planning to ride out long outages on solar should take the S5000 and size the array to use its inputs.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: Twice the rated cycles flips which unit is cheaper to own.
cost / lifetime kWh
Here's where the shelf price misleads. Per watt-hour bought, the Elite 400 is cheaper; per kWh delivered over its rated life, it costs half again as much as the S5000, 12 cents against 8, because it's rated for 3,000 cycles to the S5000's 6,000.
BLUETTI's own product page confirms the 3,000+ ratingB0, so this isn't a cautious guess that a later spec sheet will correct.
Growth Path
Selected because: The S5000 can add up to five batteries; the Elite 400 stops at 3,840Wh.
solar input
The Elite 400 is sealed at 3,840Wh, and the S5000 already beats that before adding anything. Expansion takes it further: up to five BP5000 packs through a 400V DC port, 30,144Wh in allA6.
That's the route from essentials backup toward running most of a house without replacing the base unit. The Elite 400 owner who outgrows it buys a second station.
What the Specs Don't Tell You
Selected because: The cards cover UPS speed, Power Lifting and cycle life, three places these two genuinely differ.
rated cycles
The UPS ratings are both ceilings, no more than 10 ms for the S5000 and no more than 15 ms for the Elite 400, and the second sits right at the line where the fussiest desktop power supplies drop out. Power Lifting lets the Elite 400 run a heater rated up to 3,900W by feeding it less power than it asks for, which keeps a kettle going and does nothing for a fridge compressor.
The cycle-life card is the one that changes the money, and the lifetime section above already does that arithmetic.
Portability & Form Factor
Selected because: A 12 lb gap between two wheeled units is smaller than it looks.

Scenario math and per-appliance runtimes, modeled from the spec record.
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 Elite 400 finishes the weekend at 64% used with 1,164Wh 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 Elite 400 finishes at 50% with 1,619Wh, 98% 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
Either unit
A CPAP is about 40W for eight hours, so both cover the night many times over and the capacity margin is a formality. Both happen to list 30dB — two makers' own figures landing on the same number rather than a measured tie — so there is nothing in the noise column to separate them either. Buy whichever is cheaper or easier to carry.
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

Tailgate Party
Game day power for the crew
Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 85 lbs the Elite 400 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 SOLIX S5000 comes up 415Wh short (about 91% covered) (its nameplate 5,024Wh actually clears this — the flat 15% conversion allowance is what tips it under), the Elite 400 1,421Wh (69%). 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, on Power Score margin
Buy the S5000. For 12 lb more than the Elite 400 it carries 1,184Wh more, outputs 4,500W against 2,600W, adds 240V and RV outlets, and is rated for twice the cycles, which makes it the cheaper of the two per lifetime kWh. The Elite 400 is the pick only if the $1,101 difference is a hard limit and nothing you own runs on 240V.

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, SOLIX S5000 rates 4.6/5 (74th percentile of 20 Home Backup-class units), and Elite 400 rates 3.7/5 (21st 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 Elite 400 (85 lbs) is manageable solo but heavier than a large checked suitcase. The SOLIX S5000 (97 lbs) is noticeably heavier. That's a 12 lb difference.
Elite 400: Fixed Capacity
The Elite 400 is sealed at 3,840Wh — fine if that covers you, but it's the ceiling. By contrast the SOLIX S5000 can add expansion batteries, though the first thing it has over the Elite 400 is its own 5,024Wh base — expansion is the step after that, for the buyer who would outgrow 5,024Wh as well.
Elite 400: Power Lifting to 3,900W
The Elite 400 has BLUETTI's Power Lifting mode, which runs a resistive appliance rated up to 3,900W from its 2,600W inverter. It does that by delivering less power than the appliance asks for, not more than the inverter has: the heater still works, it just heats more slowly. Two things follow. BLUETTI scopes the mode to purely resistive loads — a heater, a kettle, an incandescent lamp — so it does nothing for a fridge compressor, a pump or a power tool, and this record publishes no surge figure at all, so read the mode as a resistive-load feature rather than as starting ability. And it is not a reason to size down, because running a load that big from 3,840Wh is a short session either way. Genuinely useful if a heater or a kettle is why you're buying; beside the point otherwise. The SOLIX S5000 publishes no equivalent.
UPS Switchover: ≤10ms vs ≤15ms
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 Elite 400 is rated ≤15ms — 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. The Elite 400's figure is a maximum rather than a guarantee — it depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. Worth saying because the per-dollar framing can suggest otherwise: the Elite 400 works out at 3.6 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 3,000. In real life: at daily use, that's 16.4 vs 8.2 years. At weekend use (twice a week), it's 58 vs 29 years. One caution reading years across different sizes: a cycle is 5,024Wh on the SOLIX S5000 and 3,840Wh on the Elite 400, so count lifetime energy — roughly 30,144 kWh against 11,520 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.

Brand trust
Anker
Ecosystem
7-8 SOLIX portable power stations across C-series (compact) and F-series (flagship), plus the X1 home energy system
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.
Community
Moderate — active Reddit (r/Anker, r/AnkerSOLIXCommunity) and growing. Benefits from Anker's massive consumer electronics brand awareness.
App experience
Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android
Unique strength
Twice the rated cycles of the Elite 400 and a split-phase 240V outlet. Against this rival Anker's case is longevity and capability, not a lower price.
Worth knowing
Support quality appears to be declining from its historically excellent level. Firmware updates have removed features without warning. Expansion ecosystem is smaller than EcoFlow's.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.
Analyst note
Both carry a 5-year term, BLUETTI's on direct or registered purchases. With coverage level, the brand factor that matters is support for a unit this heavy: neither ships back easily, so buy from the maker and register on arrival.
Growth path
SOLIX S5000
EXPANDABLESupports Anker expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 5,024Wh.
Accepts up to 3,000W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Expansion batteries are Anker-specific. You're investing in the Anker ecosystem.
Elite 400
FIXED CAPACITYFixed at 3,840Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 1,000W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.

Analyst note
The Elite 400 is sealed at 3,840Wh, which is fine if that covers you. The SOLIX S5000 starts at 5,024Wh and can grow beyond it with Anker expansion batteries — real headroom the Elite 400 doesn't have if your needs climb toward partial-home backup.

Who Should Buy Which
Buy the SOLIX S5000 if you…
- →Your house has a generator inlet or a 240V well pump and you want one box that feeds it.
- →You'll cycle the station often, off solar or to shift power, and want the lower cost per lifetime kWh.
- →You own an RV with a 30A shore cord and want to plug it straight in.
Buy the Elite 400 if you…
- →Your outage list is fridge, router, lights and phones on 120V, and the $1,101 difference matters more than headroom.
- →You want a resistive heater or kettle to keep working through an outage, and Power Lifting covers exactly that.
If neither fits
If you need a station you can carry by its handle, both are the wrong class; look at a compact portable instead. And if you want the whole house on battery automatically, a hardwired home system with a transfer switch is a better tool than either.
The Bottom Line
At 85 lb against 97, nobody is choosing the Elite 400 to carry it. Choose on what the box does at home and the S5000 wins: more battery, 240V and RV power, and twice the rated cycles, which leaves it cheaper per kWh over its life.
Buy the Elite 400 only if the upfront gap decides it. Otherwise, roll the S5000 into the garage.

For home backup, yes. It carries more battery, adds 240V and RV outlets, and is rated for twice as many cycles, which makes it cheaper per lifetime kWh. The Elite 400 wins only on upfront price.
Does the BLUETTI Elite 400 have a 240V outlet?
No. Our record lists no 240V or 30A RV outlet on the Elite 400, and its output tops out at 2,600W on 120V. The S5000 has an L14-30R for 240V and a TT-30R for an RV.
How long does the Elite 400 battery last compared with the S5000?
The Elite 400 is rated for 3,000 cycles and the S5000 for 6,000 to 80% capacity. Cycled daily, that's about 8 years against 16. Used weekly, both outlast any reasonable ownership.
Which charges faster from solar, the S5000 or the Elite 400?
The S5000, by a wide margin on paper: two inputs totalling 3,000W against the Elite 400's 1,000W. At full rated input that's under two hours to fill the S5000 and close to four for the Elite 400, assuming you own enough panels to reach those ratings.
