Goal Zero Yeti 300 vs Goal Zero Yeti 500X
One of these is rated for 4,000 trips to empty and the other for 500, and the extra capacity doesn't buy its way out of that.

Spec deltas
Take the Yeti 300, and take it despite the fact that it holds less. Over its rated life the 300 will deliver 1,188 kWh of energy and the 500X will deliver 249, which is nearly five times the total, from the $350 unit rather than the $500 one.
The 500X wins one thing outright and it's worth naming first. A CPAP night draws 320Wh, which is 76% of what the 500X can actually deliver and 127% of what the 300 can. If your reason for buying a power station is a machine you sleep in front of, the smaller unit comes up short at the worst possible hour, and no cycle rating fixes that.
What's strange about this pair is that the bigger battery is also the slower one. The 500X takes less from a panel, gives less through USB-C, runs a smaller inverter, and has no UPS mode at all. Its 200Wh advantage (497Wh against 297Wh) is the whole of its case, and it arrives with a 500-cycle battery attached to it.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
Divide each price by the energy it buys and the 300 works out to $0.29 per lifetime kWh against the 500X's $2.01. That's about seven times as much for every watt-hour the 500X will ever hand you, on top of the higher sticker price. There is no feature on either spec sheet that closes a gap that size.
Yeti 300: 4,000 rated cycles at 297Wh, or 1,188 kWh over its lifeYeti 500X: 500 rated cycles at 497Wh, or 249 kWh over its life$350 for the 300, $500 for the 500X
Why it mattersIf you'll cycle this thing regularly, on weekends or in a work van or a shop, the 300 is the cheaper unit twice: once at the register and again every time you use it.
solar input
That inverts the capacity story the moment you're off the grid. In the time the 300 takes to fill completely, the 500X has pulled in roughly 180Wh at its 120W ceiling, about a third of itself. Plugged into a wall during a rolling outage the 300 is back in service inside an hourA2, so across a multi-day event it hands you its full charge again and again while the 500X is still working on its first refill.

Why it mattersAnyone recharging from panels, or from short windows of grid power, should treat the 300 as the larger battery, because it's the one that keeps coming back.
Nightly duty is exactly where a 500-cycle rating bites. At one cycle a day the ratings work out to about 11 years for the 300 and about a year and a half for the 500X, so the buyer who most needs the 500X's capacity is the buyer who wears it out fastest. Its rating is 500 cycles to 80% capacity rather than to zeroB1, which means it won't die on you. It will just quietly stop covering the night you bought it for.
A CPAP overnight needs 320Wh: 76% of the 500X's usable energy, 127% of the 300'sYeti 500X: rated 500 cyclesYeti 300: rated 4,000 cycles
Why it mattersA CPAP user should either buy the 500X expecting to replace it, or skip both and put the money into a larger LFP unit that covers the night for a decade.
Put the 300 inline with a modem, a router and a laptop, and a power cut becomes a non-event, with the laptop still charging at 100W over USB-C while it happens. The 500X will power a device and charge at the same time, but nothing hands the load over when the wall dies, and its USB-C tops out at 60W. Capacity is no consolation to a machine that just rebooted.

Why it mattersAnyone shopping for desk or home-office backup should stop here and take the 300; this is the one difference that changes what the product is.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: Same brand, same size class, $150 apart, and one of them costs $70 a year to own across its warranty while the other costs $250.
cost / lifetime kWh
Goal Zero prices its own confidence here, and it isn't subtle about it. The 300 carries five years of warranty and the 500X two, which spreads the purchase across coverage at $70 a year against $250. The cheaper box is also the one the manufacturer will stand behind for more than twice as long.
The only buyer this argument doesn't reach is the one who never gets near the cycle counter. Charge it in September, sit on it through hurricane season, empty it twice a year, and 500 cycles is a number you'll never meet. Everyone else is buying something they intend to use, and use is precisely what the 500X charges for.
Runtime: Will It Power Your Gear?
Selected because: The 500X holds 497Wh to the 300's 297Wh, and this is where that difference either matters to you or doesn't.
continuous output
Neither of these runs a kitchen. Push the 300 near its rated output and it protects itself: one reviewer had it shut down two minutes into a coffee makerA3. The 500X asks even less of its inverter, 300W continuous against the 300's 350W, so the bigger battery is also the one with the lower ceiling. What both do genuinely well is the desk-and-shelf load, and owners of the 500X report two laptops, a Nintendo Switch, an iPad and a stack of phones off one unit without troubleB3.
The 500X holds about two-thirds more (497Wh against 297Wh), which buys another evening of that same work, not another day of it. Weight won't break the tie either, at 13.7 lbs against 12.9, both of them one-hand carries. If your honest answer to 'how long does this need to run' is longer than an evening, you're in the wrong size class and neither of these is the fix.
What the Specs Don't Tell You
Selected because: Four cards fire here, and one of them, the 300's UPS switchover against the 500X having none, is where a desk buyer stops reading.
rated cycles
Four cards fire below and three of them point the same way. The one to act on is UPS. The 300 switches to battery in under 20 milliseconds, so your modem never notices the outage; the 500X has no UPS mode, so whatever is plugged into it goes down with the grid. Between two units this close in size and price, that's the line between a backup battery and a backup system.
What no card says is that the two of them surge identically, both at 600W. Every heavy load that stops the 500X stops the 300 at exactly the same wattage. This matchup is settled by lifespan, refill speed and what happens the instant the grid drops, not by what either one can start.
Your Life, Your Pick
Selected because: Five of the six workloads below come back 'neither', and the sixth is the only job the 500X wins.
Five of the six workloads below come back 'neither', and that's the most useful thing this table tells you. A camping weekend asks for 2,100Wh and a day of van life asks 4,685Wh; the larger of these two stores 497Wh. Both can start what those days ask them to start. They simply run out, early, every time.
The exceptions are worth knowing. The CPAP night is the one scenario with a winner and it goes to the 500X, on capacity alone. The tailgate is where both fail identically, and not on capacity: the peak draw exceeds the surge ceiling they share, so neither one gets the heavy load started in the first place.

Two nights off-grid with essential comfort
Neither unit
Neither unit covers this scenario's 2,100Wh: the Yeti 300 gets through about 12% of it and the Yeti 500X about 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
Eight hours of fridge, lights and phones wants 1,645Wh, and the bigger of these two holds 497Wh. Both can start the loads. Neither can carry them, so the verdict here is neither, and it isn't close. What these units actually do in an outage is keep the phones, the laptop and the router alive while the outage happens around you, which is worth having. It just isn't the fridge.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Yeti 500X
This is the one job on the page the 500X wins outright, and it wins on capacity alone. The night asks for 320Wh, which the 500X covers with room to spare and the 300 doesn't cover at all. Coming up short at 5 a.m. costs more than anything on the 300's side of the ledger is worth, so if this is why you're shopping, the bigger battery is the answer. Just know you'll be running it flat every night, which is the fastest way there is to spend a 500-cycle rating.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h

Remote Workday
Full work day off-grid without power anxiety
Neither unit
Neither unit covers this scenario's 910Wh: the Yeti 300 gets through about 28% of it and the Yeti 500X about 47%. Treat this as partial cover — enough for the essentials in it, not the whole list.

Neither unit
Both units stop in the same place, and it isn't capacity. The peak draw of a tailgate spread exceeds the surge ceiling these two share, so neither one gets the heavy load started, and 670Wh of demand is more than either stores anyway. Neither wins this. Bring a shorter list or a bigger battery.

Conclusion
August 4, 2026
Verdict: the Yeti 300
Buy the Yeti 300 unless you have one specific reason not to. It costs $150 less, carries five years of warranty against two, refills from a panel in a fraction of the time, and is the only one of the two that keeps a modem alive through a grid flicker. The 500X's entire case is 200Wh of extra capacity (497Wh against 297Wh), and that margin is real in exactly one place: a full CPAP night. If that night is why you're shopping, take the 500X and buy it knowing it's on a replacement schedule. If it isn't, the 300 is the better unit at the lower price, which is not a sentence you get to write often.

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, Yeti 300 rates 3.7/5 (24th percentile of 22 Personal-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.
The missing app is the least of it
The 500X has no app control, and it's the one gap on this page not worth a dollar to you. An app on a power station reports a percentage you can read off the front panel, over a Wi-Fi network that's down in the exact blackout you bought the thing for. If the 500X loses this comparison, it won't be over the app.
The 300 is a UPS. The 500X isn't.
Leave the 300 plugged in with your modem and router on it and it sits inline, taking over the load in under 20 milliseconds when the grid drops, which is the difference between a flicker and a reboot. The 500X has no UPS mode. It will run a load while it charges, but there's no automatic handoff, so when the wall power stops, so does whatever was plugged into it.
Warranty Value Comparison
The Yeti 300 gives you 14.3 years of warranty per $1,000 spent, vs the Yeti 500X's 4 years. That's 3.6× more coverage per dollar. An underrated factor if you're keeping this unit for years.
500 cycles is a date, not a number
Cycles are how you price a battery you intend to use. On a two-days-a-weekend habit the ratings work out to 38.5 years for the 300 and 4.8 for the 500X. The first number is absurd, which is the point: the 300 will die of old age or clumsiness, never of use. The second is a replacement you can put on a calendar.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Goal Zero Yeti 300
Reviewers describe the 300 as a small unit built like a bigger one: IP54 against dust and rain, rubberized corners, a handle meant for abuse, and a full recharge clocked at 50 minutesA2. Its limits get reported just as clearly. Four to six hours on a laptop or twenty to thirty phone charges is the working envelope, and pushed near its rated output it shut down two minutes into a coffee makerA3.
The consistent reservation is value on the day you buy itA4, and it's fair: $1.18 per watt-hour against the 500X's $1.01 means you're paying more for less storage. That's the honest catch on this pick. What the difference buys is a 4,000-cycle LFP pack instead of an older chemistryA1B4, and that trade only pays off if you actually use the thing.

Goal Zero Yeti 500X
The 500X reads well in the field. It's one of the most compact stations of its capacity, with portability and build quality both praisedB2, and owners report running two laptops, a Nintendo Switch, an iPad and a stack of phones off it without troubleB3. Nobody who bought it for that job seems to regret it.
The reservation is chemistry, not workmanship. It's an older Li-NMC pack rated for 500 cycles to 80% capacityB1, a clock rather than a cliff, and Goal Zero has already replaced it in the lineup with an LFP Yeti 500 carrying a far higher cycle ratingB4. Buying the 500X today means buying the version its own manufacturer has moved past.

Who Should Buy Which
Buy the Yeti 300 if you…
- →The desk with a modem, a router and a laptop on it. Under 20 milliseconds of switchover turns a grid blip into a non-event, and the 100W USB-C port keeps the laptop charging at full speed while it happens.
- →Anyone who'll use it weekly for years: a jobsite, a truck bed, a boat. IP54 and 4,000 cycles are the two specs that survive that kind of dutyA2.
- →The buyer who wants one power station for light loads and then wants to stop thinking about power stations for a decade.
Buy the Yeti 500X if you…
- →The CPAP user buying for one specific unattended night, who needs the capacity now and can accept replacing the unit sooner than they'd like.
- →The person who charges it, shelves it for hurricane season and empties it maybe twice a year. Cycle life is the one thing they'll never spend, and the extra capacity is the only thing they'll notice.
If neither fits
If you're sizing for a camping weekend, an eight-hour blackout with the fridge running (1,645Wh) or a day of van life, close this tab. The larger of these two stores 497Wh and neither comes within reach of any of those. Shop the 1,000Wh-and-up class, where running a fridge overnight is the design brief instead of the stretch goal.
The Bottom Line
Take the Yeti 300. It's the smaller battery and the better buy, because cycles multiply and capacity doesn't: the 300 gets to deliver its charge thousands of times where the 500X gets hundreds. Every other difference on this page happens to point the same direction. Longer warranty, faster solar, more USB-C, and a UPS mode the 500X simply doesn't have.
The one honest reason to buy the 500X is a night you can already describe: a CPAP that needs more than the 300 holds and won't wait. Buy it for that, buy it knowing you're on a replacement schedule, and don't buy it for camping. If your list runs longer than that one night, you're not choosing between these two at all.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Goal Zero Yeti 500X worth $150 more than the Yeti 300?
Only if you need the extra 200Wh on a specific night you can already name. The 500X stores 497Wh to the 300's 297Wh, and that's the entirety of its advantage: it charges slower from solar, delivers less through USB-C, runs a smaller inverter, carries two years of warranty against five, and is rated for 500 cycles against 4,000. If the capacity isn't solving a defined problem, the extra $150 is buying you less machine.
Which one can run a CPAP all night?
The 500X. A CPAP night draws about 320Wh, which is roughly three-quarters of what the 500X can actually deliver and more than the 300 holds at all. The catch is that a CPAP is a nightly load, and nightly use runs through the 500X's 500-cycle rating in about a year and a half. If this is a permanent medical setup rather than a camping trip, buy a larger LFP unit instead.
Does the Goal Zero Yeti 500X have a UPS mode?
No. The 500X will power a device and charge at the same time, but nothing hands the load over to the battery when grid power stops, so anything plugged into it goes down with the outage. The Yeti 300 does have UPS switchover, under 20 milliseconds, which is what you need for a modem, a router or a desktop.
Should I wait for the newer LFP Goal Zero Yeti 500 instead?
If you're buying the 500X for its capacity, look at that unit first. The 500X uses an older Li-NMC pack rated for 500 cycles, and Goal Zero has already replaced it in the lineup with an LFP Yeti 500 rated for far more. Between the two units on this page, the 300 is already the LFP option, at $350 with a 4,000-cycle rating.
Will either of these run a fridge?
Both can start one; neither can keep it going. An eight-hour blackout with a fridge in it needs 1,645Wh, and the larger of these two stores 497Wh. High-draw kitchen appliances are a separate problem entirely: the two share the same 600W surge ceiling, and one reviewer had the 300 shut down two minutes into a coffee maker.
