Head-to-head test
EcoFlow TITAN 5000 Plus vs BLUETTI Apex 300 + B500K
The Plus earns its premium only with a 240 V source or a large solar array behind it: solar or grid power flowing in carries its 41.7 A outlet past 7,200 W, a 240 V source drives its 7,660 W recharge, and without either you're paying more for 2,867 Wh less battery than the Apex.

Spec deltas
The BLUETTI Apex 300 + B500K costs $400 less than the TITAN 5000 Plus and stores 7,884.8 Wh to the Plus's 5,017.6 WhA7. Everything the Plus offers back is power, not energy.
Most of that power story needs a source behind it, and the fast charge needs 240 V. The display shows 10 kW out and 8 kW inA5, but the label puts battery output at 7,200 W, with the rest of the 10 kW needing solar or grid power flowing inA1, and the fast charge is a 120/240 V split-phase feed into the second AC port, rated up to 7,660 WA15. Plug the Plus into an ordinary 120 V outlet and it draws 15 A at mostA9.
So the Plus is the right box for a particular house: a 240 V generator or utility feed, a big split-phase circuit to run through it, and loads that top the Apex's 3,840 W. For a home riding out a grid-down night on battery alone, the Apex's bigger tank is the better buy.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
In a blackout with nothing feeding it, the headline outlet is a 7,200 W outlet with a bigger plug. That's still 3,360 W more than the Apex can push, but it's the battery output EcoFlow's plain TITAN 5000 already hasA1, so the Plus's premium over the Apex is mostly paying for output above 7,200 W that you only get with solar or grid power flowing in.
TITAN 5000 Plus label: Total Output 10 kW Max, 7200W for discharge only; the 10 kW needs solar or grid power flowing inA1TITAN 5000 Plus: 120/240 V split-phase at 41.7 A, against 30 A on the TITAN 5000A27,200 W divided by 240 V is 30 A
Why it mattersIf nothing 240 V will ever feed it, the big outlet is no reason to pay more than the Apex.
That changes what a generator is for. Instead of running all evening to keep a battery topped up, a 240 V generator can refill the Plus in one short session and shut off, and a smaller tank that refills that fast stops being a weakness over a multi-day outage. Without the 240 V feed, the fast charge simply isn't on the menu.
TITAN 5000 Plus AC IN/OUT port: 120/240 V split-phase input, up to 7,660 W in charge-only modeA15TITAN 5000 Plus display reads 8.00 kW inA5TITAN 5000 Plus pack: 5,017.6 WhA7; 120 V wall inlet: 100–120 V, 15 A maxA9
Why it mattersOwners of a 240 V generator get the most from the Plus; everyone else is paying for a charge path they'll never plug into.
Capacity
It also has more places to plug in. The Plus offers two ordinary 20 A sockets and one big split-phase outletA3, and EcoFlow bundles it with its 240 V Smart Home Panel 10 for whole-home wiringA6; the Apex has six AC outlets on the unit. For essentials plugged in directly, the cheaper unit lasts longer and takes more plugs.
Apex 300 + B500K: 7,884.8 Wh against the Plus's 5,017.6 WhA78-Hour Blackout: the Apex ends with 5,057 Wh usable, 3.1 more nights; the Plus with 2,620 Wh, 1.6 more nightsTITAN 5000 Plus outlets: two 120 V 20 A sockets and one 14-50-pattern 41.7 A outletA3; Apex: six AC outlets on record
Why it mattersA grid-down household with no generator, plugging essentials straight in, gets more hours and more sockets from the Apex for less money.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: On battery alone the Apex's 7,884.8 Wh outlasts the Plus's 5,017.6 Wh at every load, and that's most of the Apex's case.
continuous output
Pick any load in the runtime table and the Apex runs it more than half as long again, because 7,884.8 Wh against 5,017.6 Wh is the same ratio at every load. The Plus's 7,200 W inverter doesn't move that number. Watts decide what you can run; watt-hours decide for how long.
The Plus's reply happens between nights, not during them. A 240 V generator feeding the AC IN/OUT port at up to 7,660 WA15 can top it back up each morning, which is how a smaller tank keeps pace with a bigger one across a long outage. No 240 V source, no reply.
Growth Path
Selected because: The Plus scales to 30,105.6 Wh and takes 8,000 W of solar to the Apex's 2,400 W, which is how it can close the runtime gap, at a further cost.
solar input
The Plus can close the runtime gap, but only by spending more. Its label allows six identical 5,017.6 Wh packs for 30,105.6 WhA8, and the first extra pack puts it past the Apex. That's an expansion purchase stacked on a unit that already costs $400 more.
The solar side is cleaner. The Plus takes 8,000 W across two 40–450 V inputsA4 against the Apex's 2,400 W, so a big array keeps a growing Plus bank fed in a way the Apex's ceiling can't. If your recharge plan is panels rather than a generator, that input is the Plus's strongest card after the inverter itself.
Brand Trust
Selected because: A unit sold as part of a whole-home system makes the maker's software and support part of the purchase.
EcoFlow sells the Plus bundled with its 240 V Smart Home Panel 10 and pitches the line as whole-home backupA6, so you're buying into a system and its software. EcoFlow's record there has one blemish worth knowing: an early-2025 test of subscription paywalls on advanced app features, paused after community backlash.
BLUETTI's risk sits in the support queue rather than the app, which rates 4.5 on both stores. Support is mostly email on China hours and outcomes vary widely, and buying direct from BLUETTI tends to go better than buying through a third party.

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 Plus is 121.3 lbs and the Apex 300 + B500K 183 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.

Apex 300 + B500K
Both survive the night. The Apex 300 + B500K finishes at 25% used with 5,057Wh left — 3.1 more nights like it. The TITAN 5000 Plus finishes at 39% with 2,620Wh, 1.6 more nights like it. 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
TITAN 5000 Plus
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 TITAN 5000 Plus is rated 39dB against the Apex 300 + B500K's 45dB. 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.

Both power your workstation all day without strain. The Apex 300 + B500K lists 100W of USB-C for direct laptop charging; the TITAN 5000 Plus carries no USB-C at all, so a laptop there goes through the inverter and you are carrying its brick.

The 670Wh 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.

Apex 300 + B500K
The TITAN 5000 Plus doesn't finish — 4,265Wh usable against the 4,685Wh this needs leaves it 420Wh short, about 91% of the scenario covered (its nameplate 5,018Wh actually clears this — the flat 15% conversion allowance is what tips it under). The Apex 300 + B500K covers it with 2,017Wh to spare.

Conclusion
October 4, 2026
Verdict: the Apex 300 + B500K
Buy the Apex 300 + B500K unless a 240 V source or a large solar array is part of your plan. Both of the Plus's signature upgrades lean on one: its 41.7 A outlet carries more than the battery's 7,200 W only while solar or grid power is flowing inA1A2, and its charge path of up to 7,660 W needs a 240 V split-phase feed into the AC IN/OUT portA15. What's left without that source is a 7,200 W inverter against the Apex's 3,840 W, decisive only if your simultaneous load tops 3,840 W, and a battery 2,867 Wh smaller for $400 more.

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 Plus rates 4.7/5 (84th percentile of 20 Home Backup-class units), and Apex 300 + B500K rates 3.5/5 (11th percentile of 29 Whole-Home / Off-Grid-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 Plus (121.3 lbs) is a two-person lift. The Apex 300 + B500K (183 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 62 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
Apex 300 + B500K: 45dB Published
45dB is about as loud as a running refrigerator. The TITAN 5000 Plus is rated 39dB — 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 Apex 300 + B500K is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The TITAN 5000 Plus 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. The Apex 300 + B500K'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.

Analyst note
The TITAN 5000 Plus 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.
Brand trust
EcoFlow
Ecosystem
Largest in portable power — 12-15 models across DELTA Pro, DELTA 3, and RIVER 3 series, plus solar panels and smart home panels
Support
US-based phone/email/chat support (1-800-368-8604). Experiences are polarized — many report hassle-free prepaid-label replacements, but others report long waits and refurbished units sent for new claims. Pro tip: buying from Costco or Amazon gives you a stronger return safety net.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the top of the range sit two whole-home paths: the TITAN line, one 5 kWh unit that grows to 30 kWh, and the DELTA Pro Ultra platform, which stacks batteries and inverters further — flagship paths, not line-wide features.
Worth knowing
Tested subscription paywalls for advanced app features in early 2025 before community backlash paused the plan. No parts or service offered out of warranty.
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
EcoFlow is building a 240 V home ecosystem around this unit, panel included, on top of the deepest catalogue in portable power; BLUETTI's pitch is capacity for the price, and this pairing proves the point. Pick EcoFlow for the system, BLUETTI for the battery.

EcoFlow TITAN 5000 Plus
Everything on record for the Plus is EcoFlow's own documentation plus our reading of itA0. The rating label fixes battery output at 7,200 W inside a 10 kW total that needs solar or grid power flowing inA1, a 120/240 V split-phase outlet rated 41.7 AA2A3, a second AC port that charges at up to 7,660 W from a 240 V feedA15, 8,000 W of solar input across two portsA4, and the shared 5,017.6 Wh packA7 with a 30,105.6 Wh ceilingA8.
“"Total Output: 10 kW Max (7200W for discharge only)" — the battery delivers 7,200 W, the same as the TITAN 5000; the 10 kW total includes grid pass-through.”
BLUETTI Apex 300 + B500K
Our research found almost nothing tied to this exact B500K pairing and nothing from six months of ownership; most reports describe the bare Apex 300 or its B300K bundleB0. What carries across is the base unit's character.
Reviewers consistently call the fans even and quiet for the class, quiet enough for an indoor workspace in one accountB13B1. One reviewer could barely carry the base unit a few feetB11, and this bundle weighs 183 lbs across its boxes. Owners also report firmware updates that misfired, one locking the unit in Backup modeB7 and one ending in an inverter-output errorB9.
“Turns out the Apex 300's noise control is on par with the quietest power stations on the market, like those on offer from EcoFlow and DJI.”

“X-Fusion 2.0: solar powers the home first, then charges TITAN for after dark; at peak rates TITAN runs the home on stored energy, and working with the grid through the main panel it can power loads beyond the backed-up circuits.”

Who Should Buy Which
Buy the TITAN 5000 Plus if you…
- →The house with a 240 V portable generator: feed it into the AC IN/OUT port and the Plus refills at up to 7,660 WA15, so the generator runs briefly instead of all evening.
- →A home with a big split-phase circuit to back up and loads that regularly top 3,840 W at once, where the 14-50-pattern outletA3 and 7,200 W from the batteryA1 earn their keep.
- →The solar-first build planning a large array and a multi-pack bank: 8,000 W of input across two portsA4 and room for six packsA8.
- →A grid-tied home with existing rooftop solar that wants it to keep working with the battery: EcoFlow says the Plus AC couples with compatible panelsA20.
Buy the Apex 300 + B500K if you…
- →The grid-down household with no generator, running a fridge, a freezer, lights and the internet straight off the unit's six outlets.
- →Anyone who wants the most stored energy for the money in this matchup.
- →The rural home where outages are counted in nights, and the bigger tank is the insurance.
If neither fits
Anyone who wants the Plus's 7,200 W but has no 240 V source to feed it should skip both and look at EcoFlow's plain TITAN 5000, which delivers the same battery output through a 30 A split-phase outletA1A2; the Plus's extra amperage needs solar or grid power flowing in, which this buyer may never supply.
The Bottom Line
The Plus's headline numbers, 10 kW out, 8 kW in and 41.7 A, all need a 240 V source behind them to mean more than its battery delivers. Without one, you're paying $400 more for a battery 2,867 Wh smaller, and the Plus's remaining edge is its 7,200 W inverter.
Generator owners and big-circuit houses with loads past 3,840 W: take the Plus. Everyone riding out outages on battery alone: take the Apex and enjoy the extra nights.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the EcoFlow TITAN 5000 Plus really output 10kW?
Not from its battery. The label reads 10 kW total with 7,200 W for discharge only, so everything above 7,200 W needs solar, grid or generator power flowing in. On battery alone the Plus delivers the same 7,200 W as the TITAN 5000.
How fast does the TITAN 5000 Plus charge?
Up to 7,660 W in charge-only mode, from a 120/240 V split-phase feed into its AC IN/OUT port; that's where the 8 kW reading on its display comes from. At that rate the 5,017.6 Wh pack refills in well under an hour on paper. From an ordinary 120 V outlet it draws 15 A at most.
What is the 41.7A outlet on the TITAN 5000 Plus for?
It's a four-pin 14-50-pattern outlet rated 120/240 V at 41.7 A, built for a large split-phase circuit. On battery alone, 7,200 W at 240 V works out to 30 A, so the extra headroom only comes into play when solar, grid or generator power is flowing in.
Is the BLUETTI Apex 300 + B500K better value than the TITAN 5000 Plus?
On stored energy, yes: it holds 7,884.8 Wh to the Plus's 5,017.6 Wh and costs $400 less. The Plus earns its price only if you need more than the Apex's 3,840 W at once or will feed it from a 240 V source.
What does the TITAN 5000 Plus add beyond the spec sheet?
The TITAN 5000 Plus's X-Boost 2.0 gives up to 5 kW on each 120 V leg. EcoFlow's X-Fusion 2.0 has solar power the home first and the battery cover peak-rate hours. EcoFlow lists the TITAN 5000 Plus as UL 9540 certified and tested to UL 9540A. The TITAN 5000 Plus can AC couple with compatible existing rooftop solar, which needs the Smart Home Panel 10 and a CT sensor.
