Spec deltas
The BLUETTI AC240P (1,843Wh) and Goal Zero Yeti 500X (497Wh) sit in different weight classes. The real question: do your power needs justify the larger unit, or would you be overpaying for capacity that sits unused? The AC240P has a slight edge, but the margin is close enough that your use case should break the tie.
What the spec gap means in practice: the AC240P's 2,400W inverter has the headroom for a window AC, a full-size fridge, and power tools. The Yeti 500X's 300W inverter can't run the heaviest of those — a window AC or a high-surge power tool needs more than it can hold, whatever its 1,200W surge ceiling does at the instant of startup. On stamina, the AC240P keeps a fridge alive for roughly 10 hours vs the Yeti 500X's 3 hours. The cost? Portability. At 72 lbs, the AC240P is heavy enough to make you think twice about moving it. The Yeti 500X at 12.9 lbs is something one person can actually carry.
Pick the AC240P if your primary use is remote workday or tailgate party. Go with the Yeti 500X if its specific strengths below line up better with your use. Most buyers stop at the sticker price and miss this: over a full lifespan the AC240P works out to about $0.23/kWh against the Yeti 500X's $2.01, a gap that compounds in the AC240P's favor the more you cycle it. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.
Bench Notes
What each unit does well, where it falls short, and the trade-offs that matter.
BLUETTI AC240P
With a massive 2,400W output (and 3,600W surge), the AC240P can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 72 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Longer warranty
- +Faster solar charging
- +Rated for 3,500 charge cycles — much longer battery lifespan
Trade-offs
- –Substantially more expensive (+$962) than the Yeti 500X.
- –Significantly heavier (+59.1 lbs), making it harder to move.
Goal Zero Yeti 500X
At 300W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 12.9 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Costs $962 less
- +Lighter by 59.1 lb
Trade-offs
- –Weaker inverter (-2,100W) limits appliance compatibility.
- –Lacks smartphone app control for remote monitoring.
- –Sealed capacity — the AC240P can add batteries to grow past 497Wh; this one can't.
- –Shorter-lived battery — rated for 500 charge cycles vs the AC240P's 3,500, so it wears out sooner.

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
Neither unit covers this scenario's 2,100Wh: the AC240P comes up 533Wh short (about 75% covered), the Yeti 500X 1,678Wh (20%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
This scenario needs 1,645Wh and neither unit quite finishes it. The AC240P lands within 5% of it — close enough that trimming one appliance, or accepting a shorter evening, gets you there on the day.
Battery budget usedlower = more headroom
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 with room to spare and capacity decides nothing. Fan noise would — but Yeti 500X 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.

LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
AC240P
The Yeti 500X doesn't finish — 422Wh usable against the 910Wh this needs leaves it 488Wh short, about 47% of the scenario covered. The AC240P covers it with 657Wh to spare.

SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
AC240P
The Yeti 500X can start the 400W peak but not hold it — 1,200W of surge gets it going, then the 300W continuous rating takes over. The AC240P handles this scenario with 897Wh to spare.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the AC240P comes up 3,118Wh short (about 33% covered), the Yeti 500X 4,263Wh (9%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

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, AC240P rates 3.9/5 (35th percentile of 27 Everyday-class units), and Yeti 500X rates 3.5/5 (14th percentile of 22 Personal-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.
AC240P: 72 lbs Is a Commitment
At 72 lbs, this is manageable but not fun to move. That's heavier than a large checked suitcase. How much it costs you depends on whether it rolls — wheels and a telescoping handle change the job completely at this weight, and our spec record doesn't track them, so look at the product photos before you plan on carrying it from the car.
AC240P: 45dB Published
45dB is about as loud as a running refrigerator. It is BLUETTI's own rating rather than a reading on a shared bench — makers differ on whether they quote a best case or a figure under load, so treat it as a starting point rather than what you would hear at a bedside. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Yeti 500X: No App Control
Without app control, you have to physically walk to the Yeti 500X to check battery level, adjust settings, or monitor power draw. The AC240P lets you do all that from your phone, including getting low-battery alerts.
Yeti 500X: Fixed Capacity
The Yeti 500X is sealed at 497Wh — fine if that covers you, but it's the ceiling. By contrast the AC240P can add expansion batteries, though the first thing it has over the Yeti 500X is its own 1,843Wh base — expansion is the step after that, for the buyer who would outgrow 1,843Wh as well.
Surge Power: Ratio and Ceiling Disagree
The Yeti 500X holds the higher surge-to-continuous ratio (4× vs 1.5×), but the AC240P holds the higher absolute surge ceiling — 3,600W against 1,200W. These measure different things. The ratio says how much headroom an inverter keeps above its own rating; the ceiling says how big a startup spike it can actually swallow. A motor draws a number of watts at switch-on, not a multiple of someone else's rating, so on raw starting ability the AC240P is the stronger unit here — while the Yeti 500X is the one running further below its own limit at steady state.
Only the AC240P Lists a UPS Mode
The AC240P can sit between the wall and your gear and hand it to battery when the grid drops — rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. Worth it for a router, a desktop PC, or a CPAP. The Yeti 500X's spec sheet lists no UPS mode, so anything plugged into it rides an outage only as far as your reaction time.
Warranty: 6 Years vs 2
The AC240P is covered for 6 years against the Yeti 500X's 2 years. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The AC240P is rated for 3,500 cycles vs 500. In real life: at daily use, that's 9.6 vs 1.4 years. At weekend use (twice a week), it's 34 vs 5 years. One caution reading years across different sizes: a cycle is 1,843Wh on the AC240P and 497Wh on the Yeti 500X, so count lifetime energy — roughly 6,451 kWh against 249 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 500X: Noise Level Not Disclosed
The AC240P publishes its noise level (45dB); the Yeti 500X doesn't publish one. That isn't evidence the Yeti 500X 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 AC240P'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 500X before deciding.
Full record above — the Test Desk pick is the AC240P.

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 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.
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 company (Salt Lake City, owned by NRG Energy). Historically considered premium support, but 2025-2026 reports describe long wait times, unresponsive email communication, and tickets going unaddressed for weeks. The "premium support justifies premium pricing" argument is weakening.
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
Goal Zero positions itself as a premium brand with stronger support infrastructure, while BLUETTI competes on value. The question is whether the Goal Zero ecosystem and support premium is worth it for your use case.
Growth path
AC240P
EXPANDABLESupports BLUETTI expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,843Wh.
Accepts up to 1,200W 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 BLUETTI-specific. You're investing in the BLUETTI ecosystem.
Yeti 500X
FIXED CAPACITYFixed at 497Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 120W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
The Yeti 500X is sealed at 497Wh, which is fine if that covers you. The AC240P starts at 1,843Wh and can grow beyond it with BLUETTI expansion batteries — though at this size expansion means longer runtimes on the same loads, not a path to home backup. More hours, not more house.
The Bottom Line
The full picture comes down to this. The AC240P edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the Yeti 500X wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the AC240P nor the Yeti 500X feels like the right fit, your power needs probably sit outside what these two target. Use our comparison tool above to explore alternatives that better match your specific wattage and runtime requirements. Prices on portable power stations fluctuate frequently. Both BLUETTI and Goal Zero discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the AC240P worth $962 more than the Yeti 500X?
The short answer: yes, if you'll actually use the extra capability. The AC240P costs $962 more, but that premium buys you 1,346Wh more battery capacity (that's 8 extra hours of running a mini-fridge); 2,100W higher AC output (opening the door to more demanding appliances); a longer-lasting battery rated for 3,500 cycles — that's 10 years at daily use; 1,080W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $0.79/Wh vs $1.01/Wh. Factor in cycle life and the math flips: the AC240P costs $0.23/kWh over its lifetime vs $2.01/kWh. The "expensive" unit is actually cheaper to own. For regular use, we'd pay the premium.
How does the 1,346Wh capacity difference actually affect daily use?
The AC240P's 1,843Wh battery keeps a mini-fridge running for roughly 10 hours vs the Yeti 500X's 3 hours. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The AC240P's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Can I actually carry the AC240P, or is the Yeti 500X the only portable option?
The Yeti 500X at 12.9 lbs is genuinely grab-and-go. Toss it in a backpack, carry it one-handed to a picnic, take it on a boat. The AC240P at 72 lbs is a different story. It's like carrying a large suitcase full of books. If you're setting up and breaking down camp frequently, this weight difference will exhaust you by day two.
How fast can each unit recharge from solar panels in real conditions?
On paper, the AC240P accepts 1,200W vs the Yeti 500X's 120W of solar input. What the spec sheet won't tell you: solar panels typically deliver only 60-80% of their rated output due to panel angle, cloud cover, and temperature. In realistic conditions, expect full recharge in about 2.2 hours for the AC240P and 5.9 hours for the Yeti 500X. That gap widens on cloudy days, when the AC240P's higher input ceiling captures more of whatever sunlight is available. One more thing: summer gives you ~7 productive solar hours per day. Winter drops to ~4. If solar is your primary recharge method, the AC240P's advantage is substantial.
"3,500 vs 500 cycles" — what does that actually mean for me?
In real years: the AC240P (3,500 cycles) lasts 9.6 years at daily use, 34 years at weekend use (twice a week), or 146 years at twice-monthly camping trips. The Yeti 500X (500 cycles): 1.4 years daily, 5 years weekends, or 21 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 1,843Wh unit becomes a ~1,474Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Can I use the AC240P as a home UPS to protect my electronics during blackouts?
Yes. The AC240P has UPS mode that keeps your devices running through power transitions. Plug in your desktop PC, router, NAS, or CPAP machine and it switches to battery seamlessly when the grid drops. The Yeti 500X does not have this feature. Without UPS, a blackout means: your PC reboots (potentially corrupting unsaved work), your NAS may corrupt its drive array, your CPAP alarms and wakes you up, and your security cameras go dark until you manually switch them over. If always-on power protection matters, this is a dealbreaker advantage for the AC240P.
What if I need more capacity than the Yeti 500X's 497Wh later?
The Yeti 500X is sealed at 497Wh, so if you expect your needs to climb, the AC240P is the more future-proof pick: it starts at 1,843Wh and adds BLUETTI-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own — if 497Wh comfortably covers your loads, the Yeti 500X is a complete unit, not a downgrade.
Is BLUETTI or Goal Zero more reliable for long-term ownership?
Both brands have strengths and trade-offs. BLUETTI: 2-6 years depending on model (up to 10 years on home backup systems). Response times vary significantly. Some reports of units being deemed unrepairable with no parts available for older models. Goal Zero: 5 years on LFP models, 2 years on older NMC models. Battery must be charged within 7 days of purchase and every 6 months to maintain warranty (strict). Product reliability concerns have increased — repeat "Battery Fault" errors reported even on newer Yeti Pro 4000. One piece of advice from the power station community: regardless of brand, buy from Costco or Amazon. Their return policies provide a safety net that manufacturer warranties alone can't match, especially for a product you'll rely on in emergencies. Both brands use LFP (lithium iron phosphate) batteries in their current lineup, the most proven chemistry for longevity and safety.
Bottom line: should I buy the AC240P or the Yeti 500X?
We'd pay the premium for the AC240P. Yes, it costs more. The capability jump is real: you're stepping into a tier that handles appliances the base model can't start. The Yeti 500X is still solid if budget is the priority, but the AC240P will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
