EcoFlow TITAN 5000 Classic vs Anker SOLIX F3800
The Classic carries more battery, but it speaks only 120 V, and for whole-home backup the F3800's 240 V outlets and 6,000 W settle this before capacity gets a vote.

Spec deltas
The TITAN 5000 Classic cannot power a 240 V circuit. EcoFlow's rating label gives it 4,000 W at 120 V and nothing elseA1, so a well pump, dryer, range or central air on a two-pole breaker stays dark no matter how full the battery is. The Anker SOLIX F3800 has two 240 V outlets, 6,000 W of continuous output, and costs $599 less.
What the Classic offers in return is battery: 5,017.6 Wh against 3,840 Wh, plus 3,200 W of solar input against 2,400 W. Those are honest advantages. They only start counting once the 240 V question has gone the Classic's way, which happens in exactly one kind of home: the one where everything you need through an outage runs on 120 V.
So the call is the F3800 for nearly everyone shopping at this size, and the Classic for the 120 V-only house that wants the longest runway per charge. If you don't know which house you live in, the nameplate on your well pump does.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Anything wired to a two-pole breaker gets nothing from the Classic at any state of charge, while the F3800 feeds it and still has 2,000 W more to spend on the rest of the house (6,000 W minus 4,000 W). Capacity can't buy back a missing voltage.
TITAN 5000 Classic: 4,000 W continuous at 120 V only, no 240 V split-phaseA1EcoFlow bundles the Classic with its 120 V Smart Home Panel 10; the TITAN 5000 and Plus get the 240 V versionA4SOLIX F3800: 6,000 W continuous, two 240 V outlets
Why it mattersIf a well pump, dryer, range or central air is on your outage list, cross the Classic off yours.
Capacity
That extra margin shows up on the second morning without power, when the F3800 is nearly spent and the Classic still has a cushion. In a 120 V house it is the Classic's entire argument, and it is a fair one for $599 on top of the F3800's price.
Classic: 5,017.6 Wh, 4,265 Wh usable after the flat 85% derateF3800: 3,840 Wh, 3,264 Wh usable8-Hour Blackout load: 1,645 Wh; the Classic ends it with 2,620 Wh left, the F3800 with 1,619 Wh
Why it mattersA 120 V-only household where outages routinely run into a second day is the one buyer the Classic should win.
solar input
Where they part ways is how easy that input is to feed. The F3800's is the complaint its owners repeat, with one using it only when nothing else will charge the unitB1. The Classic's label publishes a plain 30–250 V windowA3 that a string of panels you already own can be checked against before you buy.
Classic solar: 3,200 W max across a 30–250 V MPPT windowA3F3800 solar: 2,400 W maxF3800 owners consistently report its solar input is hard to use with panels other than Anker'sB1B2B13B14
Why it mattersA 120 V off-grid cabin with an array already up leans Classic; a grid-tied home that charges from the wall can skip this chain entirely.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: None of the six scenarios needs 240 V, so this grid shows the Classic's battery lead at full strength and hides its one disqualifier.
Every row here peaks at 400 W or less, a load either inverter shrugs at, which is why the Classic looks strong across the board. The row worth reading is the 8-Hour Blackout: 39% of the Classic used against 50% of the F3800. The camping and tailgate rows don't describe a battery whose label places it in a utility spaceA9, so read past them.
What no row tests is a 240 V appliance. Add a well pump on a two-pole breaker to this grid and the Classic would have nothing to offer it, however much charge it had left.
Runtime: Will It Power Your Gear?
Selected because: The Classic's 1,177.6 Wh lead is the reason to consider it at all, and runtime is where that lead turns into hours.
continuous output
After the same flat derate, the Classic has 4,265 Wh to spend and the F3800 3,264 Wh, roughly 1,000 Wh more usable energy. For a fridge, a gas furnace's blower and the lights on 120 V, that difference is the next morning.
The ceiling sits lower, though. The Classic's 4,000 W is the most it runs at once, all at 120 V, against the F3800's 6,000 W. Its 120 V 30 A portA2 is the natural socket for feeding a 120 V transfer switch, carrying up to 3,600 W (120 V × 30 A) down one cord, so add up what runs together before you decide capacity is your bottleneck.
Growth Path
Selected because: Both expand, and the Classic's 30,105.6 Wh ceiling shows how far a 120 V system can grow before the voltage question comes back.
solar input
Six packs take the Classic to 30,105.6 WhA6, and every one of those watt-hours still leaves the box at 120 V. Expansion adds hours, not volts.
The F3800 grows too, with Anker's expansion batteries, and it grows on 240 V. So the real choice for an expanding home is a battery-heavy system on one voltage against a smaller one on two. If your house might ever add a 240 V load, buy the voltage now; batteries are the part you can always add later.

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
Neither unit
Scoring these two at a campsite is a category error: neither travels — the TITAN 5000 Classic is 102.5 lbs and the SOLIX F3800 132.3 lbs, and at those weights they roll off a truck bed if they go anywhere at all. The 2,100Wh here is trivial for either — it's the going that doesn't happen. If you need power away from the building, you're shopping the wrong class.

TITAN 5000 Classic
Both survive the night. The TITAN 5000 Classic finishes at 39% used with 2,620Wh left — 1.6 more nights like it. The SOLIX F3800 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.

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 with room to spare and capacity decides nothing. Fan noise would — but SOLIX F3800 doesn't publish a figure, so there's nothing to hold it to. Buy on price, weight, and whether you can live with a fan you haven't heard.

Neither unit
Scoring these two at a tailgate is a category error: neither travels — the TITAN 5000 Classic is 102.5 lbs and the SOLIX F3800 132.3 lbs, and at those weights they roll off a truck bed if they go anywhere at all.

Neither unit
Neither unit covers this scenario's 4,685Wh: the TITAN 5000 Classic comes up 420Wh short (about 91% covered) (its nameplate 5,018Wh actually clears this — the flat 15% conversion allowance is what tips it under), the SOLIX F3800 1,421Wh (69%).

Conclusion
October 4, 2026
Verdict: the SOLIX F3800
Buy the Anker SOLIX F3800. It runs 240 V loads the Classic cannot touch, puts out 6,000 W against 4,000 W, and costs $599 less. The Classic's 1,177.6 Wh of extra battery is real: its 4,265 usable Wh covers the site's 1,645 Wh blackout night 2.6 times, where the F3800's 3,264 Wh covers it just under twice. That margin only decides anything in a house where every circuit you care about is 120 V, so settle that question before you read another spec.

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, TITAN 5000 Classic rates 3.8/5 (32nd percentile of 20 Home Backup-class units), and SOLIX F3800 rates 4.5/5 (68th 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 TITAN 5000 Classic (102.5 lbs) is a two-person lift. The SOLIX F3800 (132.3 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 30 lb difference.
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 SOLIX F3800 works out at 2.5 years of cover per $1,000 spent against the TITAN 5000 Classic's 1.9, but that spread is the price gap, not the terms.
SOLIX F3800: Noise Level Not Disclosed
The TITAN 5000 Classic publishes its noise level (30dB); the SOLIX F3800 doesn't publish one. That isn't evidence the SOLIX F3800 is louder — it means there's no figure to hold it to, and no way to compare the two on this without hearing them. If you're buying for a bedroom, a CPAP, or an apartment, treat the TITAN 5000 Classic's 30dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the SOLIX F3800 before deciding.

Analyst note
The TITAN 5000 Classic has no published cycle rating, so its lifetime rows use the average of the 28 LiFePO4 units EcoFlow does rate: about 3,400 cycles. That's a fair baseline for the brand but not a rating for this unit, so cost to own isn't scored on it. Judge these two on price, capacity and warranty, and read the rows marked "est." as a ballpark.

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.
Analyst note
EcoFlow positions itself as a mid-to-premium brand with stronger support infrastructure, while Anker competes on value. The question is whether the EcoFlow ecosystem and support premium is worth it for your use case.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow TITAN 5000 Classic
The Classic's evidence so far is EcoFlow's own published ratings. They establish a 5,017.6 Wh pack shared with the other two TITANsA5, 4,000 W continuous at 120 V onlyA1, three 20 A sockets plus one 30 A port, all at 120 VA2, and a 30–250 V solar window that tops out at 3,200 WA3. Our own reading of the label's pack voltage points to LFP cellsA11.
“4,000 W continuous output at 120 V only — no 240 V split-phase.”
Anker SOLIX F3800
Most of what F3800 owners have said lives in a single DIY Solar Forum thread, and there are no CPAP or long-term reports in what we foundB0. One of those owners feeds a transfer switch from a single 120 V outlet and runs everything he's tried through it, a water pump includedB5. Solar is the shared gripe: one uses it only when nothing else will charge the unitB1, and another says it steers you toward Anker's own pricier panelsB2.
“I have been using the F3800 for a couple weeks now, using only a single 120V outlet into a reliance transfer switch and it runs everything I throw at it including a water pump.”

Who Should Buy Which
Buy the TITAN 5000 Classic if you…
- →A house where the outage list is a fridge, a gas furnace's blower, a 120 V sump pump and the lights, nothing on a two-pole breaker, and where outages tend to run into a second day.
- →An off-grid 120 V cabin with a string of panels already up that fits inside the Classic's 30–250 V windowA3.
- →A 120 V home on time-of-use rates that wants automatic bill-lowering: EcoFlow lists an AI TOU Mode on the ClassicA22.
Buy the SOLIX F3800 if you…
- →Anyone with a 240 V well pump, dryer, range or central air they want running through an outage.
- →A buyer who wants the most inverter for the money: 6,000 W for $2,000.
- →A home that recharges from the wall or a generator between outages, where the Classic's bigger solar input would never get used.
If neither fits
Two people should close this tab. If you wanted a battery for a campsite or a van, the Classic's label puts it in a utility spaceA9 and the F3800 weighs 132.3 lbs, so shop mid-size portables instead. And if it's EcoFlow's 5,017.6 Wh pack you're after but on 240 V, the TITAN 5000 and Plus carry the same packA5 and come bundled with the 240 V home panelA4.
The Bottom Line
The F3800 wins because it does the one job the Classic cannot: it runs 240 V, at 6,000 W, for $599 less. The Classic's extra battery stretches a long outage further, which is worth paying for in exactly one kind of house.
If every circuit you care about is 120 V and your outages run long, the Classic earns its price. Everyone else should check the breaker on their well pump, then go get the F3800.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the EcoFlow TITAN 5000 Classic run a 240V well pump?
No. EcoFlow's rating label gives the Classic 4,000 W at 120 V only, with no split-phase output, so anything on a 240 V breaker is out. The Anker SOLIX F3800 has two 240 V outlets and 6,000 W continuous. If your pump is a 120 V model, the Classic is back in the conversation.
Is the TITAN 5000 Classic worth paying more than the Anker SOLIX F3800?
Only in a 120 V-only home. The extra $599 buys 1,177.6 Wh more battery and 800 W more solar input, which stretches a long outage but cannot add the 240 V outlets the F3800 already has. Everywhere else, the cheaper F3800 is the better machine.
Can you add batteries to the TITAN 5000 Classic or the Anker F3800?
Yes, both expand. The Classic takes up to six packs for 30,105.6 Wh in total, and the F3800 takes Anker's expansion batteries. On the Classic, every pack you add is more runtime at 120 V; none of them adds a 240 V outlet.
Does the Anker F3800 charge well from solar panels?
It accepts 2,400 W, but owners consistently report the input is restrictive and nudges them toward Anker's own pricier panels. Some work around it with secondary charge controllers. If you plan to reuse panels you already own, check them against the input before you buy.
What does the TITAN 5000 Classic add beyond the spec sheet?
EcoFlow lists the Classic as UL 9540 certified and tested to UL 9540A, and it comes with a factory pre-wired 120 V Smart Home Panel 10 that controls 10 circuits from the app. Storm Mode charges the battery before severe weather. For bill-lowering, EcoFlow lists an AI TOU Mode with up to 3,200 W of solar input, but no X-Fusion or grid-connection row for the Classic.
