Head-to-head test
EcoFlow TITAN 5000 Plus vs BLUETTI AC500 + 2×B300K
For close to the same money, the Plus is a 240 V system that can feed a 41.7A circuit and refill from a 240 V source at up to 7,660W, while the AC500 stack is a slightly bigger 120 V battery: buy the voltage, not the 512.4Wh.

Spec deltas
The Plus is the TITAN with the big outlet: a 14-50-pattern socket marked 120V/240V 41.7AA3, beside two 120V 20A sockets. The AC500 + 2×B300K has no 240 V output at all, so the question on this page is less which battery is bigger than whether your house has a 240 V job for one to do.
Read the headline number carefully. The label's 10 kW is a total that needs solar or grid power flowing in; from its own battery the Plus delivers 7,200WA1, the same as the TITAN 5000. That's still 2,200W more than the stack's 5,000W, and it arrives on two legs instead of one.
The other thing the Plus buys is speed back in. Its AC IN/OUT port takes up to 7,660W of 240 V chargingA15, and the display shows 8.00 kW inA5. With only $249 between them, the stack's 512.4Wh lead in capacity doesn't outweigh either of those.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
The fast number belongs to the 240 V path and only that pathA15. With a generator that has a 240 V outlet, or a few hours of grid between rolling outages, the Plus turns that window into a full pack faster than its battery can empty at 7,200W. Without a 240 V source, its refill story falls back to solar and the wall.
Plus AC IN/OUT: up to 7,660W charge-only from a 120/240 V split-phase feedA15Standard wall inlet: 100–120V, 15A max, held to under three hours above 12AA9Pack: 5,017.6WhA7EcoFlow's product image shows the display at 8.00 kW inA5
Why it mattersBuy the Plus for its 8 kW path only if you have, or will install, a 240 V feed to charge it from, or will put more than 4,000 W of panels on its two solar inputsA4.
continuous output
Against the stack, both modes win. On battery, 7,200W across two legs beats 5,000W on one; on grid, the Plus carries a 41.7A, 240 V circuit straight through, while the BLUETTI can't carry a 240 V circuit in either mode. The stack's extra battery never gets a turn on the 240 V side of the panel.
Plus outlets: two 120V 20A sockets and one 14-50-pattern outlet marked 120V/240V 41.7AA3Battery output 7,200W; the 10 kW total includes grid pass-throughA1AC IN/OUT bypass up to 41.7A at 120/240 VA15AC500 + 2×B300K: 5,000W, no 240 V output
Why it mattersIf the circuit you're backing up is a big 240 V one, the Plus is the only machine here built for it.
Capacity
Wired into a home panel, the way EcoFlow sells the PlusA6, outlet count stops mattering, because your house circuits become the outlets. The stack's port advantage only counts if the system stays a plug-in box, at a cabin or an RV pad with no panel to feed.
Plus: three AC outlets on the unitA3 and no USB portsA10AC500 + 2×B300K: two 100W USB-C ports and an RV-style 30A outletPlus sold bundled with EcoFlow's 240 V Smart Home Panel 10A6Capacity: 5,530Wh vs 5,017.6Wh
Why it mattersPanel install: the Plus. A plug-in setup feeding an RV cord or a row of laptops: the stack's ports earn their keep.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: The Plus refills at up to 7,660W from a 240 V feed and 8,000W from solar, against the stack's 3,000W solar ceiling.
solar input
The Plus refills three ways. On solar, the one path the record lets us compare, it takes 8,000W across two 40–450V inputsA4 to the stack's 3,000W, 5,000W more into a smaller pack. The 240 V AC IN/OUT path at up to 7,660WA15 is the Plus's own trick: plug it into a 240 V source and the refill is counted in minutes, not afternoons.
Capacity grows the way it does on every TITAN, in matching 5,017.6Wh packs to six and 30,105.6WhA8, from a box that lives in a utility space by EcoFlow's labelA11, close to the panel it feeds. The stack expands with more BLUETTI batteries. A big bank is only as useful as your ability to refill it, and that is where the Plus pulls away.
Runtime: Will It Power Your Gear?
Selected because: The Plus's battery delivers 7,200W (its 10 kW label total needs solar or grid power flowing in) against the stack's 5,000W on 120 V.
continuous output
The stack's 436 extra usable Wh (4,701 against 4,265 after the flat 15% derate) is about 11 more hours of a 40W CPAP, or about five minutes at its own 5,000W ceiling. Capacity leads shrink fast as loads grow, and the loads that justify a Plus are big ones.
Its 7,200W reaches the house across two 120 V legs or at 240 V through the 41.7A outletA3, where the stack's 5,000W comes on 120 V only. Below 5,000W of 120 V load the two run alike. The moment a 240 V circuit joins the list, only the Plus is in the conversation.
Your Life, Your Pick
Selected because: The stack's capacity lead shows up in exactly one profile, the 4,685Wh day, and only just.
Five profiles end with both units comfortable; the blackout, for one, uses 39% of the Plus's usable battery and 35% of the stack's. The 4,685Wh day is the only one capacity decides, and it goes to the stack by a hair: 16Wh left, against a 420Wh shortfall on the Plus after the flat derate.
Treat it as a tie in practice. Finishing a day with 16Wh means recharging before the next one, same as the unit that fell short, and the Plus's 240 V charge path is built for exactly that rechargeA15.
Brand Trust
Selected because: The stack's field record is a few single-battery reports, and both makers' support files argue for buying where returns are easy.
Neither maker's support file is a selling point. EcoFlow's experiences are polarized, its US phone line helps, and it offers no parts or service out of warranty; BLUETTI's is the least consistent in the category and email-first. On a panel-wired install, buy from whoever makes the return easiest, which EcoFlow's file says means Costco or Amazon and BLUETTI's says means buying direct.
The stack's evidence is a handful of reports on the AC500 with one B300KB0. They split between smooth runningB1B12 and arrival trouble, a missing cable in one caseB6 and a dead inverter in anotherB7, plus everyday quibbles like the lack of a hard resetB8.

Scoring these two at a campsite is a category error: neither travels — the TITAN 5000 Plus is 121.3 lbs and the AC500 + 2×B300K 196.1 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.

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 AC500 + 2×B300K 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.

Either unit
Both power your workstation all day without strain. The AC500 + 2×B300K 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.

Conclusion
October 4, 2026
Verdict: the TITAN 5000 Plus
Buy the Plus. It delivers 7,200W from its battery on 120/240 V split-phaseA1A2, against the stack's 5,000W on 120 V alone, and it can take up to 7,660W of charging from a 240 V feed through its AC IN/OUT portA15, at $3,699 to the stack's $3,948. The AC500 + 2×B300K keeps 512.4Wh more battery and an RV-style 30A outlet; those win the page only for a 120 V setup that plugs an RV cord straight into the box.
At today's prices the AC500 + 2×B300K is the cheaper unit ($3,299 against $3,699, with the AC500 + 2×B300K $649 under its typical $3,948). At typical prices the TITAN 5000 Plus is ($3,699 against $3,948), and that is what the verdict weighs. Prices checked 28 days ago.

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 AC500 + 2×B300K rates 4.1/5 (47th percentile of 20 Home Backup-class units).

Weight Reality Check
Neither unit is grab-and-go. The TITAN 5000 Plus (121.3 lbs) is a two-person lift. The AC500 + 2×B300K (196.1 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 75 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
Warranty: 5 Years vs 4
The TITAN 5000 Plus is covered for 5 years against the AC500 + 2×B300K's 4 years. An underrated factor if you're keeping this unit for years.
AC500 + 2×B300K: Noise Level Not Disclosed
The TITAN 5000 Plus publishes its noise level (39dB); the AC500 + 2×B300K doesn't publish one. That isn't evidence the AC500 + 2×B300K 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 Plus's 39dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the AC500 + 2×B300K before deciding.

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
Neither maker promises to keep a panel-wired system alive past its warranty: EcoFlow offers no parts or service once it ends, and BLUETTI has no spare-parts policy for some models. Plan as if the warranty period is the support period, whichever you buy, and buy through the channel each file favors: a big retailer for EcoFlow, direct for BLUETTI.

Both expand, but the TITAN 5000 Plus's higher solar ceiling (8,000W vs 3,000W) 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 TITAN 5000 Plus
The Plus's evidence is EcoFlow's own published ratings rather than field reports. The label gives 7,200W from the battery within a 10 kW total that needs solar or grid power flowing inA1, split-phase output at 41.7AA2 and 8,000W of solar across two 40–450V inputsA4. It also rates the AC IN/OUT port for up to 7,660W of 240 V chargingA15, and EcoFlow's product image shows 8.00 kW inA5.
“"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 AC500 + 2×B300K
Everything in the field record describes the AC500 paired with one B300K, not two, so trust its findings on noise and polish more than any runtime numberB0. The fan gets mixed notes: loud when it runs but intermittent, per one reviewerB10, and quieter than a smaller Pecron, per an ownerB1.
Living with it has small frictions. One owner misses a time-remaining or battery-voltage readoutB2 and found it drawing about 35W above the actual load on grid powerB3; a reviewer says the always-on indicator lights rule out a bedroomB11. On arrival, one owner's battery cable was missingB6 and a reviewer's inverter stayed deadB7.
“So far pretty darn happy, and it's much quieter than the small Pecron E1500LFP I have.”

Who Should Buy Which
Buy the TITAN 5000 Plus if you…
- →A house with a big 240 V circuit to back up, where the 41.7A, 14-50-pattern outletA3 and the 41.7A pass-throughA15 are the whole point.
- →Anyone with a 240 V generator or a grid window to charge from: up to 7,660W in through the AC IN/OUT portA15.
- →A solar build that will grow: 8,000W of input against 3,000W, and packs up to 30,105.6WhA4A8.
- →A house with many 120 V loads on one side of the panel: EcoFlow lists X-Boost 2.0 for the Plus, up to 5 kW on each 120 V leg, so more 120 V appliances run together without load balancingA24.
Buy the AC500 + 2×B300K if you…
- →An RV owner who wants to plug a 30A RV cord straight into the box: the stack has the RV-style outlet and the Plus doesn't.
- →A 120 V plug-in setup, like a cabin with no panel, that values two 100W USB-C ports and the extra 512.4Wh more than 240 V.
If neither fits
A 120 V home with no 240 V circuit to back up and no 240 V source to charge from. The Plus's two headline extras would sit idle and the stack's edge is a battery only a tenth bigger; a 120 V whole-home unit is the better fit.
The Bottom Line
Take the Plus. Its battery runs 7,200W across both legs, its 41.7A outlet and pass-through are built for the big 240 V circuit the stack can't touch, and a 240 V feed refills it faster than it can drain. The stack's 512.4Wh lead is real and small. Unless an RV cord is the plan, buy the voltage.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow TITAN 5000 Plus really 10kW?
Only as a total that needs solar or grid power flowing in. EcoFlow's label reads 10 kW max with 7,200W for discharge only, so on battery the Plus delivers 7,200W, the same as the TITAN 5000. That's still 2,200W more than the AC500 + 2×B300K's 5,000W.
How does the TITAN 5000 Plus charge at 8kW?
Through its AC IN/OUT port, from a 120/240 V split-phase feed, at up to 7,660W in charge-only mode; the display shows 8.00 kW in. The ordinary wall inlet is 100–120V at 15A, so the fast refill needs a 240 V source such as a generator or a dedicated circuit.
TITAN 5000 Plus or AC500 for an RV?
For a 30A RV cord, the AC500 + 2×B300K: it has the matching RV-style 30A outlet and the Plus does not. The Plus's big socket is a 14-50-pattern outlet marked 120V/240V 41.7A, so check your RV's plug before assuming either one fits.
Which has more battery, the TITAN 5000 Plus or the AC500 + 2×B300K?
The AC500 stack, by 512.4Wh: 5,530Wh against the Plus's 5,017.6Wh. The Plus expands in matching 5,017.6Wh packs up to 30,105.6Wh and the AC500 takes more BLUETTI batteries, so neither is stuck at its starting size.
What does the TITAN 5000 Plus add beyond the spec sheet?
EcoFlow lists X-Boost 2.0 for the Plus, up to 5 kW on each 120 V leg so more 120 V appliances run together without load balancing, and X-Fusion 2.0, where solar powers the home first and the battery covers peak-rate hours. It is UL 9540 certified and tested to UL 9540A, and EcoFlow's OASIS 3.0 forecasts solar 3 days ahead and charges off-peak, but the store marks it a subscription feature in the EcoFlow app.
