BLUETTI Apex 300 + 2×B300K vs Goal Zero Yeti 700
The Apex takes every row on this page and that settles nothing: one of these you carry to the car with one hand, the other is three boxes you install once and never move again, so the only real question is whether your load fits inside 575Wh.

Spec deltas
Twelve times the capacity for a bit over five times the price: 8,294.4Wh against 677Wh, $3,699 against $700. That ratio is also the least useful thing on this page, because these two aren't substitutes. One of them fits behind the driver's seat. The other one is furniture.
The number that actually decides it is 575Wh. That's the Yeti 700's 677Wh after the flat 15% usable derate we apply site-wide, and it's the wall the scenario table keeps hitting. Five of the six load profiles we model land on the far side of it. The sixth, a CPAP night, sits comfortably inside, and that sixth one is why this page exists: if that's your load, then $700 and 20.3 lb is the entire answer.
The Apex 300 + 2×B300K clears all six, which is what $3,699 and ten times the weight ought to buy. It arrives as a base unit plus two B300K batteries totalling 213.9 lb, it goes to one spot, and it stays there. So the question isn't which unit is better. It's which of those two paragraphs describes your house.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
At a 320Wh night it takes 26 nights to spend one of the Apex's 3,500 cycles (8,294.4 divided by 320), so the cheap-energy figure is priced for a life this unit will never live in that household. The Yeti's 26 cents is spent on a box that empties most nights, which makes it the number a light user can actually collect.
Apex 300 + 2×B300K: $3,699 buys 8,294.4Wh rated for 3,500 cycles, or 29,030 lifetime kWh at $0.13 per kWhYeti 700: $700 buys 677Wh rated for 4,000 cycles, or 2,708 lifetime kWh at $0.26 per kWhThe CPAP Overnight profile draws 320Wh a night
Why it mattersIf you can't name a load that empties 8,294Wh on a schedule, the per-kilowatt-hour advantage is not money you will ever see.
weight
That changes what you're buying more than the capacity does. The Apex goes to one place and stays, which is right for a utility room and useless at a trailhead; the Yeti goes where you go and comes back, which is right at a trailhead and irrelevant in a utility room. Capacity is the spec people compare and placement is the spec they live with.
Apex 300 + 2×B300K: 213.9 lb total, and 8,294.4Wh is BLUETTI's own 2,764.8Wh Apex 300 figure three times over — a base unit plus two batteriesReviewers and van-conversion owners put the base box alone at 38kg and describe the result as a stationary install rather than something carriedA12A13Yeti 700: 20.3 lb holding 677Wh
Why it mattersIf the unit has to move more than once a season, capacity stops being the deciding number and weight starts.
solar input
The parity lives in the numbers, not in the yard. The Apex's 2,400W is only as good as an array you can build inside a 60V windowA8, and a detection fault that needs a physical replug is a very different problem when the panels are on a roofA9. The Yeti's 200W has no conditions attached to it. It also caps at 200W, which is the honest other half of that sentence.
Apex 300 + 2×B300K: 2,400W solar input against 8,294.4Wh of storageYeti 700: 200W solar input against 677Wh of storageOwners call the base unit's 60V solar ceiling the single most-cited complaintA8, and report solar input going undetected until the cables are unplugged and replugged, which BLUETTI has acknowledged as a firmware issueA9
Why it mattersOff-grid buyers should price the panel string and the wiring before treating 2,400W as capability they already own.
Headroom also isn't what settles this page, because the Apex holds twelve times the Yeti's capacity before you add anything, and a growth path only counts when the expanded ceiling beats the rival's. Buy this system for the 8,294Wh you're paying for today. Treat the next battery as something to verifyA1A2A3 rather than something to bank on.
The Apex 300 + 2×B300K already ships as a multi-box configuration and accepts further BLUETTI expansion batteriesOwners running more than one pack report them charging out of step, one at 100% while another sits at 50%, with BLUETTI support calling that normalA1A3One owner says he asked BLUETTI for video of an Apex 300 charging above 1,200 watts and that none was producedA2
Why it mattersIf your reason for choosing the Apex is what it can become rather than what it already is, get charge-sync behaviour confirmed before you order.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: The Yeti 700 clears one of the six load profiles we model and the Apex 300 + 2×B300K clears all six, so this table is the fastest way to find out which class of unit you're actually shopping for.
Five of the six profiles end the same way, and the size of each miss is the useful part. A remote workday leaves the Yeti 700 335Wh short, which is the annoying kind of gap: close enough that a lighter setup would fit, far enough that this one doesn't. A van-life day leaves it 4,110Wh short. That isn't a gap you manage, it's a category error.
The one profile both units clear is the one a lot of people quietly buy these for. A CPAP night is 320Wh, roughly 40W for eight hours, which is 5% of the Apex and still leaves the Yeti 255Wh in hand at sunrise. Fan noise would normally break a tie like that, and here it can't, because only BLUETTI publishes a figure. So it breaks on money and floor space instead, and on those two a 20.3 lb box at $700 isn't a compromise. It's the correct answer.
Portability & Form Factor
Selected because: 20.3 lb against 213.9 lb spread over three boxes is the difference between gear you take places and an appliance you install.
weight
The Yeti 700 travels and the Apex doesn't, and no other spec on this page overrides that. 20.3 lb is a one-hand carry with the cooler in the other hand. The Apex arrives as three separate boxes, and the reviewers and van-conversion owners who have lived with one describe it as a stationary installation rather than something you take placesA12A13.
That's the honest catch against the bigger unit and it belongs here, before the capacity column talks you out of it: 8,294Wh you can't move is not a superset of 677Wh you can. If the trip involves a footpath, the scenario table is answering a question you didn't ask.
Lifetime Value
Selected because: Thirteen cents per lifetime kilowatt-hour against twenty-six is real, but it only arrives if you genuinely cycle 8,294.4Wh, which is the whole argument on this page.
cost / lifetime kWh
Thirteen cents a lifetime kilowatt-hour against twenty-six. Up front it reads the same way, 45 cents a watt-hour against $1.03, so on both measures the Apex 300 + 2×B300K is the cheaper energy and it isn't close.
The catch is in the denominator. Those 29,030 lifetime kilowatt-hours assume 3,500 complete drains of 8,294.4Wh, and under that kind of use the Apex reaches the end of its rated cycles in 9.6 years while the Yeti's 4,000 cycles stretch to 11. Nobody reading this is doing that. Cheap per kilowatt-hour is only cheap if you buy the kilowatt-hours, so let the capacity justify the price and treat the lifetime figure as confirmation rather than as the reason.
Growth Path
Selected because: Expansion is the Apex 300 + 2×B300K's structural advantage over a sealed 677Wh box, and it comes with a caveat worth reading before you pay for it.
solar input
Expansion matters less here than almost anywhere else on the site, because the Apex 300 + 2×B300K holds twelve times the Yeti 700's capacity before you add a thing to it. A growth path only counts when the ceiling you expand to beats the rival's, and this one cleared that in the box.
The part to read twice is what living with multiple packs is actually like. Owners running more than one report them charging out of step, one sitting at 100% while another sits at 50%, with BLUETTI support describing that as normalA1A3; one owner says he asked for video of an Apex charging above 1,200 watts and never got itA2. That's a caveat on the configuration you're buying today, not a worry about some battery you might add years from now.
Brand Trust
Selected because: At $3,699 the support queue is part of the purchase, and these two brands are in very different places on that.
At $3,699 the support desk is part of the product, and BLUETTI's is a coin flip. One owner describes two weeks of troubleshooting, another week to get an RMA approved, and no reply 48 hours after chasing an updateA4; the wider picture owners paint runs from great and helpful to notoriously non-existentA11. Our brand assessment adds that buying direct from BLUETTI rather than through a reseller tends to produce the better outcome, which is worth remembering if a marketplace listing undercuts the direct price.
Goal Zero is the opposite kind of risk. Our brand assessment puts it as a Salt Lake City company that built its premium on support and has been giving that ground back, with long waits, unanswered tickets, and the official community forums closed. At $700 that's an inconvenience you can absorb. At $3,699 it would be a deciding factor, which is the one way the Yeti's smallness works in its favour on this page.

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
Neither unit
The Yeti 700 finishes this weekend 1,525Wh short of the 2,100Wh the profile asks for, which isn't a shortfall you plan around so much as a smaller trip. Bring device charging and lights and it's fine; bring anything with a heating element and it isn't. The Apex spends 30% of itself on the same weekend, which is its own kind of warning: you'd be hauling three boxes to a campsite so your entire weekend could register as a rounding error.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Apex 300 + 2×B300K
An eight-hour outage wants 1,645Wh and the Yeti 700 brings 575Wh of it, so it covers about a third of the night. The Apex uses 23% of itself and could run the same night three more times over before it needed the grid back. If your reason for buying is the storm that takes the street out until Tuesday, that reserve is the entire product.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both clear this one. 320Wh is 5% of the Apex, and a little over half of what the Yeti has to give, which still leaves 255Wh in hand at sunrise. Fan noise would normally settle a dead heat like this, but only BLUETTI publishes a figure, so there's nothing to compare it against. Break it on price and floor space instead: $700 and 20.3 lb, or $3,699 and three boxes, to run the same 40W all night.

Apex 300 + 2×B300K
910Wh of laptop, monitor, and lights puts the Yeti 700 335Wh short, and that's the most frustrating kind of miss: close enough that a leaner desk would fit inside it, far enough that this one doesn't. The Apex spends 13% of itself on the same day. If you work from a van rather than a picnic table, that's the difference between planning your afternoon and not thinking about it.

Tailgate Party
Game day power for the crew
Neither unit
Ninety-five watt-hours. That's the entire margin by which the Yeti 700 misses a 670Wh tailgate, and it's the best argument on this page against buying right up to the edge of a spec. The Apex covers it on 10% of the pack and you'd never think about it again, though you'd also have to get three boxes across the parking lot, which rather defeats the tailgate.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Apex 300 + 2×B300K
This is the profile the Apex was built for and the one that ends the argument. 4,685Wh a day is 66% of the system and roughly eight times what the Yeti 700 can supply, and even here the Apex holds 2,365Wh back for the day the sun doesn't show up. The Yeti isn't in this conversation, and no amount of solar makes it so.

Conclusion
August 9, 2026
Verdict: the Apex 300 + 2×B300K, on Power Score margin
Call it a tie, because they answer different questions. The dividing line is 575Wh, which is what the Yeti 700 has left to give after the flat 15% usable derate this site applies to every unit. Loads under that line belong on the cheap, light box, and buying 8,294.4Wh to serve them means paying for headroom you will never touch. Loads over it aren't a stretch for the Yeti, they're a different product: the eight-hour blackout profile sits 1,070Wh beyond what it can supply, and no habit or setting closes that. So find your real number first. Under the line, buy the Yeti 700. Over it, the Apex 300 + 2×B300K earns its price and its floor space, and the Yeti is not a cheaper version of it.

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, Apex 300 + 2×B300K rates 3.4/5 (7th percentile of 29 Whole-Home / Off-Grid-class units), and Yeti 700 rates 3.6/5 (16th percentile of 20 Compact-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
213.9 lb, and Not in One Piece
This isn't one heavy box, it's three: a base unit plus two B300K batteries adding up to 213.9 lb. So whether two people can lift it is the wrong question. The right one is whether you've chosen the spot, because once the three of them are sitting in a corner cabled together, that's where they live. The Yeti 700's 20.3 lb is the other model entirely, and it goes in the car.
45dB Under Load, and the Only Published Figure Here
BLUETTI rates the Apex 300 + 2×B300K at 45dB under load, which is about a fridge humming in a quiet kitchen. It's a rating, not something measured beside a bed. Goal Zero publishes nothing for the Yeti 700, so this is the only noise number on the page, and having one is not the same as being the louder unit. If you're buying for a bedroom, weigh 45dB as a reference point rather than as a mark against the Apex.
Yeti 700: Fixed Capacity
The Yeti 700 is sealed at 677Wh — fine if that covers you, but it's the ceiling. By contrast the Apex 300 + 2×B300K can add expansion batteries, though the first thing it has over the Yeti 700 is its own 8,294Wh base — expansion is the step after that, for the buyer who would outgrow 8,294Wh as well.
Surge Power: Inverter Quality Indicator
The Apex 300 + 2×B300K has a 2× surge-to-continuous ratio vs the Yeti 700's 1.7×, and the higher absolute ceiling with it — 7,680W against 1,000W. At 2× it clears the 2× rule of thumb for absorbing motor startups — fridges, AC compressors and power tools briefly draw 2-3× their rated wattage. What decides whether a given motor starts is the ceiling, not the ratio: the Yeti 700 still surges to 1,000W, so check the startup draw of the heaviest thing you plan to run against that figure rather than assuming it trips.
10ms vs 20ms: Both Are Stated Ceilings
The Apex 300 + 2×B300K is specified to switch to battery within 10ms and the Yeti 700 within 20ms. Both are manufacturer ceilings rather than stopwatch results, and neither has been timed here. At those figures both sit in the range people run desktops, routers, and networking gear behind, and the difference between them is not what should decide this purchase. If you're protecting something genuinely intolerant of a gap, check that equipment's own ride-through spec rather than buying either unit on the strength of a number in a table.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The Apex 300 + 2×B300K'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 Yeti 700 works out at 7.1 years of cover per $1,000 spent against the Apex 300 + 2×B300K's 1.4, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The Apex 300 + 2×B300K is rated for 6,000 cycles vs 4,000. In real life: at daily use, that's 16.4 vs 11 years. At weekend use (twice a week), it's 58 vs 38 years. One caution reading years across different sizes: a cycle is 8,294Wh on the Apex 300 + 2×B300K and 677Wh on the Yeti 700, so count lifetime energy — roughly 49,766 kWh against 2,708 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.
Yeti 700: Noise Level Not Disclosed
The Apex 300 + 2×B300K publishes its noise level (45dB); the Yeti 700 doesn't publish one. That isn't evidence the Yeti 700 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 Apex 300 + 2×B300K's 45dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the Yeti 700 before deciding.

Analyst note
The Yeti 700 is cheaper to buy, but the Apex 300 + 2×B300K is cheaper to own. At $0.07/kWh over its lifetime vs $0.26/kWh, the Apex 300 + 2×B300K's higher cycle life and capacity make each dollar go further over the years.
Brand trust
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 biggest variable in owning one of these. It's email-based, routed through a China timezone, and the outcomes are genuinely polarized: some claims move quickly, others turn into weeks of back-and-forth or an offer of a discount on a new unit instead of a repair. Buying direct from BLUETTI rather than through a marketplace reseller tends to go better, which is worth factoring in at this price.
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.
Goal Zero
Ecosystem
Focused — a compact current line (6th-gen Yeti and Yeti Pro series), the previous-gen X series now out of stock across every model on Goal Zero's own store (checked 2026-09-13: 200X, 500X, 1000X, 1500X, 3000X, 6000X, some listed only as open-box), so buying one new means finding retailer stock, Sherpa power banks for the under-100Wh tier, plus Alta coolers, Nomad/Ranger solar panels, and vehicle integration kits
Support
US-based out of Salt Lake City, which used to be the whole pitch. The recent record is weaker: long waits, emails that go unanswered for weeks, and the official community forums shut, which took a self-help channel down with them.
Community
Small but loyal — strong following in overlanding and preparedness communities. Official community forums were recently shuttered, frustrating long-time users.
App experience
Rated 4.4/5 iOS (~1,200 ratings) but recent reviews skew negative — recurring connectivity issues, crashes, and stability problems.
Unique strength
Pioneer of the portable power market — strongest brand heritage. US-based company with ruggedized, weather-resistant designs (IP ratings vary by model). Integrated "Yeti-Ready" ecosystem with coolers, lights, and vehicle kits.
Worth knowing
Typically the priciest brand per watt-hour — though individual pairings vary, and on some pages the Yeti is the cheaper energy. Support quality has declined from its "premium" standard. Perceived as competitively stagnant vs. faster-innovating Chinese competitors. Reliability reports on newer models are concerning.
Analyst note
One brand is the value leader with a support desk you may have to chase; the other is the heritage name whose support advantage has been quietly eroding. At $700 that difference is an inconvenience. At $3,699 it's part of what you're buying, so weigh it on the Apex side of the page rather than the Yeti's.
Growth path
Apex 300 + 2×B300K
EXPANDABLESupports BLUETTI expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 8,294Wh.
Accepts up to 2,400W of solar. Enough for a serious multi-panel array.
Generous port selection supports complex multi-device setups.
Expansion batteries are BLUETTI-specific. You're investing in the BLUETTI ecosystem.
Yeti 700
FIXED CAPACITYFixed at 677Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 200W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
The Yeti 700 is sealed at 677Wh, which is fine if that covers you. The Apex 300 + 2×B300K starts at 8,294Wh and can grow beyond it with BLUETTI expansion batteries — real headroom the Yeti 700 doesn't have if your needs climb toward partial-home backup.

Field evidence on this exact configuration is thin and young. The substantive voices are two DIY Solar Power Forum threads, a van-conversion thread, and hands-on reviewsA1A4A6A16, with nothing in there that reads like long-term ownership. What exists splits cleanly, and the complaints cluster on charging: packs drifting out of sync when charged together, one at 100% and another at 50%, with support calling it normalA1A3; a 60V solar ceiling that owners call misleading and a jokeA8; and solar input that stops being detected until the cables are unplugged and replugged, acknowledged by BLUETTI as a firmware issueA9.
The praise is about what it does once it's running. One reviewer measured a 20W AC idle drain and credits it with stretching runtime through long outagesA15; another found the fan steady, with no pitch change or rattle, and usable near a sleeping areaA14; the reviewer who tested an Apex 300 with a B300K said he could keep essentials running for more than a full day without carefully managing consumptionA16. On the money, a van-conversion owner priced a comparable DIY build — solar charger, split charger, shunt, inverter — and came out level or slightly higher than the ApexA6. The recurring gripe that isn't a fault: the base unit ships with no DC or USB ports on its face, and the Hub D1 that adds them is a separate $300 accessory bolted on afterwardsA10A17.
“For me the 240V output is great. I can stick it in the back of my PHEV and use the 240V output to charge at 3.3KW when I stop.”
Goal Zero Yeti 700
The Yeti 700's ledger is short and mostly descriptive rather than experiential. It's a 6th-generation 677Wh unit on LiFePO4 rated for 4,000+ cyclesB1, it carries an IPX4 rating and is built for rough outdoor useB2, and the one independent review in hand frames it as lightweight and simple, good for quick camping trips and device charging rather than for powerB3. Its billing as the LFP replacement for the older NMC X-series comes from Goal Zero itself, so read that as a product claim rather than a findingB4. There's no long-term owner reporting here to weigh against the specs, and nothing contradicting them either.
“A 6th-generation 677Wh compact power station on upgraded LiFePO4 chemistry rated for 4,000+ cycles — daily use for over 10 years.”

Recurring owner themes
- When multiple Apex 300 units (as in this 2x-B300K configuration) are charged together, owners report state-of-charge sync problems and solar input capped far below the advertised rating, which Bluetti support has called 'normal' behavior. [Apex 300 + 2×B300K · 3 entries]
- Customer/RMA support experience is inconsistent — some owners report smooth help, others describe multi-week delays and unresponsive tickets. [Apex 300 + 2×B300K · 2 entries]
- The base unit's 60V solar input ceiling and a firmware bug that drops solar detection (requiring an unplug/replug) are the two most-cited technical gripes among solar-focused owners. [Apex 300 + 2×B300K · 2 entries]
- Because the Apex 300 ships with no built-in DC/USB ports, owners and reviewers alike flag the mandatory ~$300 Hub D1 accessory as an unexpected added cost. [Apex 300 + 2×B300K · 2 entries]
- Despite being marketed as 'portable,' the unit's weight (~38kg/85lb base alone, more with B300K batteries) leads multiple sources to describe it as effectively a stationary/semi-permanent installation rather than something carried around. [Apex 300 + 2×B300K · 2 entries]
- Modern LFP (4,000+ cycles), IPX4 ruggedness, and light, simple portability are the highlights; modest power and capacity. [Yeti 700 · 3 entries]

Who Should Buy Which
Buy the Apex 300 + 2×B300K if you…
- →You're backing up a house circuit, a well pump, or a home office through multi-day outages, and the boxes are going in the utility room near the panel. 3,840W continuous with 7,680W of surge starts motors that the Yeti's 1,000W ceiling won't.
- →You're wiring a van or a cabin and the real alternative is a DIY stack: charge controller, split charger, shunt, inverter, batteries. One owner priced exactly that comparison and the from-scratch build came out level or slightly higherA6.
- →You need 240V. One owner charges a PHEV off the Apex's 240V output at 3.3kW when he stopsA5.
- →Your daily draw is measured in kilowatt-hours rather than device charges, and you want a full day of reserve sitting behind it.
Buy the Yeti 700 if you…
- →Everything you plug in has its own battery. Phones, a laptop, camera gear, lights: the Yeti's usable capacity covers that comfortably, and 20.3 lb means it actually comes on the trip instead of staying in the garage.
- →You want a CPAP backup that lives on the nightstand and fits in a suitcase, for $700.
- →You need something that will get rained on. It's rated IPX4 and built for rough outdoor useB2.
- →You already own the big system and want a small second unit for the tent or the truck.
If neither fits
If your honest load is a fridge, a router, and some lights through a two-day outage, both of these are the wrong shape. The Yeti 700 doesn't clear even the eight-hour profile, and the Apex is $3,699 of hardware across three boxes that will never leave the room you set it up in. What you want is a single unit somewhere between 677Wh and 8,294Wh that one person can still pick up, and that whole middle of the market exists precisely because that's where most people's answer sits.
The Bottom Line
They aren't competing, so stop trying to make them. Everything the Apex 300 + 2×B300K wins, it wins by being a bigger class of object: more energy, more surge headroom, cheaper power across a working life you'd have to genuinely live to collect on. Everything the Yeti 700 wins, it wins by weighing 20.3 lb and costing $700, and neither of those is a small win when the thing has to fit in a car.
Find your load, then buy the class. Under the line, the Yeti is right and the Apex is $2,999 of headroom sitting on your floor. Over it, the Yeti isn't a budget version of the Apex, it's the wrong tool, and the Apex is the one you set up once and stop thinking about. The only genuinely bad outcome on this page is buying the small one and hoping.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the Apex 300 have USB ports?
Our spec sheet lists 100W USB-C for the Apex 300 + 2×B300K, but the field reports say the base unit's face carries no DC or USB ports at all, and that the Hub D1 accessory which adds them is a separate $300 purchase. We're flagging that as an unresolved conflict rather than quietly picking a side. If charging off the front of the unit is part of why you're buying it, confirm the port layout of your exact bundle with BLUETTI before you order. The Yeti 700 also lists 100W USB-C, so this is not an axis either unit wins on paper anyway.
Is the Yeti 700 enough for a power outage?
For an eight-hour outage as we model it, no. That profile calls for 1,645Wh and the Yeti 700 has 575Wh to give after the flat 15% usable derate we apply to every unit, so it covers roughly a third of it. Treat it as an evening of phones, a router, and lights rather than a whole night of the house, and don't expect careful use to close the difference.
Why is the more expensive unit the cheaper one to own?
Because lifetime cost is the purchase price divided by all the energy the unit will ever deliver. The Apex 300 + 2×B300K is rated to deliver 29,030 kWh over its life against the Yeti 700's 2,708, so its $3,699 spreads a great deal further than the Yeti's $700 does. That only becomes money in your pocket if you actually put those cycles through it, and a light user never reaches the part of the curve where the Apex gets cheap.
Can I start with the Yeti 700 and add capacity later?
No. It's sealed at 677Wh with no expansion, so size it correctly at purchase. The Apex 300 + 2×B300K is the opposite case, since it's already a base unit plus two batteries and it takes more, but before you buy it for that reason it's worth knowing that owners running multiple packs report them charging out of sync, one full while another sits half charged, with support calling that expected behaviour.
How loud are these two?
Only one of them tells you. BLUETTI rates the Apex 300 + 2×B300K at 45dB under load, roughly a fridge humming in a quiet kitchen, while Goal Zero publishes no figure for the Yeti 700. That's not evidence the Yeti is the louder one, it just means there's no number to hold it to. One reviewer described the Apex's fan as steady, with no pitch change or rattle, and usable near a sleeping area; for the Yeti you'd have to hear one first.
