Head-to-head test
Goal Zero Yeti 500 vs Jackery Explorer 300
Five of seven modelled loads defeat both of these boxes, so the entire decision rests on the one they disagree about: whether the thing you plug in has to still be running in the morning.

Spec deltas
Five of the seven loads modelled on this page defeat both of these units. One is trivial for both. Exactly one separates them, and it happens to be a job people buy small stations for: a CPAP drawing 40W for eight hours, 320Wh in total. The Yeti 500 finishes that night with 104Wh still in it. The Explorer 300 runs about six of the eight hours and stops 71Wh short.
That extra night costs $211 and nine pounds. The Yeti 500 is $500 and 16.1 lbs; the Explorer 300 is $289 and 7.1 lbs. Those two figures are the Explorer 300's case, and it is not a weak one.
Take the Yeti 500 anyway. It is the unit that can be left running: a listed UPS mode rated no worse than 20ms so a grid drop does not interrupt whatever is plugged in, 500W continuous with 1,000W of surge behind it, and a pack rated for 4,000 cycles against 800. The Explorer 300's answer to all of that is that you probably do not need it. Sometimes that is true, and it is worth thinking about honestly before you spend the difference.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Now add the spec that decides what happens before the battery is even involved. The Yeti 500 lists a UPS mode rated no worse than 20ms, so it can sit between the wall and the machine and take over the instant the grid drops. The Explorer 300's spec sheet lists no UPS mode, so an outage interrupts whatever is plugged into it until somebody wakes up and re-plugs. For a device that has to run unattended overnight, the Explorer 300 comes up short twice: once on energy, once on the handover.
Yeti 500: 499Wh nameplate, 424Wh usable after the flat 15% derate applied to every unit in the catalogueExplorer 300: 293Wh nameplate, 249Wh usable on the same derateThe CPAP Overnight load is 320Wh, which is 40W held for eight hours
Why it mattersIf a CPAP, a router or a desktop has to survive both the night and the grid, stop comparing watt-hours and buy the Yeti 500.
rated cycles
That only cashes out if you cycle it. The same arithmetic puts the Explorer 300's 800 cycles at 2.2 years of daily use and 7.7 years at twice a week. Haul it out three weekends a summer and you will never come within sight of the limit, which means the strongest argument on this page is worth precisely nothing to a light user. Neither pack dies at the limit either. Both settle to about 80% of original capacity and carry on.
Yeti 500: 4,000 rated cycles at 499Wh a cycle, about 1,996 kWh of energy over the rated lifeExplorer 300: 800 rated cycles at 293Wh a cycle, about 234 kWh$0.25 per lifetime kilowatt-hour against $1.10
Why it mattersIf this unit lives in a van or gets charged most weeks, the cheap one is the expensive one. If it lives in a closet between trips, ignore the cycle math entirely and decide on weight and price.
weight
The ports argue the other way, and quietly. 100W against 60W is two-thirds more going into a laptop, and two of those sockets against one means a laptop and a phone are not taking turns. If what rides in the bag next to the battery is a laptop you actually work on rather than a phone you top up, the nine pounds you saved gets billed back at the charging port over the rest of the day.
Explorer 300: 7.1 lbs. Yeti 500: 16.1 lbsExplorer 300: one USB-C port at 60W. Yeti 500: two at 100WThe Afternoon Off-Grid load is 100Wh, leaving the Explorer 300 at 40% used and the Yeti 500 at 24%
Why it mattersBuy the Explorer 300 if the carry is the point and the loads are small. Buy the Yeti 500 the moment a working laptop is one of them.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Five of the seven modelled loads defeat both units and one suits both, so a single row decides this page: a 320Wh CPAP night.
Most of this grid is a list of things neither box can do, and that is the useful part. Weekend camping asks for 2,100Wh, a remote workday 910Wh, a day in a van 4,685Wh. The Yeti 500 has 424Wh usable and the Explorer 300 has 249Wh. Those rows are not close calls between these two units, they are a sign you are shopping the wrong shelf.
Two rows are left: an afternoon and a night. Both units clear the afternoon with room, so it settles nothing beyond what you would rather carry. The night is the whole page. Every usable figure here comes off a flat 15% derate applied to every unit in the catalogue, so read them as one consistent yardstick rather than a measurement taken on these two boxes.
Lifetime Value
Selected because: Over their rated lives these two hold about 1,996 kWh and 234 kWh of energy, and that gap is where the price difference is either repaid or wasted.
cost / lifetime kWh
Twenty-five cents a kilowatt-hour against a dollar ten. Over its rated life the Yeti 500 hands you energy at roughly a quarter of what the Explorer 300 charges for the same watt-hour, and there is no port, no app and no saved pound on the smaller box that closes a gap that size.
It is also the argument most likely to be irrelevant to you. A rated life is only spent by cycling, and at twice a week the Explorer 300's 800 cycles run 7.7 years, which is longer than plenty of people keep a small power station. Somewhere between charging it every week and hauling it out three times a summer, this section stops being a reason to spend more. You are the only one who knows which side of that line you sit on.
Portability & Form Factor
Selected because: 16.1 lbs against 7.1 is the Explorer 300's whole argument, and 100W of USB-C against 60W is the answer to it.
weight
Nine pounds is the Explorer 300's entire case and it is a real one. 7.1 lbs goes into a daypack without a conversation. 16.1 lbs is a thing you carry by the handle, in one hand, and put down when you arrive.
Then the ports argue back. The Yeti 500 runs two USB-C at 100W against the Explorer 300's single 60W socket, which is two-thirds more into a laptop and a second outlet so the phone is not waiting its turn. Weight is what you notice walking in. Charging speed is what you notice for the next six hours.
What the Specs Don't Tell You
Selected because: Only the Yeti 500 lists a UPS mode and only the Explorer 300 publishes a noise figure, and just one of those two facts changes what you can plug in.
rated cycles
Five of the six cards below point the same way, which is unusual enough to say out loud: surge headroom, UPS, warranty, cycle life and app control all fall to the Yeti 500. The sixth is the only one the Explorer 300 takes, and it is a technicality rather than a win. Goal Zero publishes no noise figure for the Yeti 500, so the Explorer 300's 36dB is the only number on the table and there is nothing to measure it against.
Take the UPS card seriously and the app card lightly. One is a capability the Explorer 300's spec sheet never claims at all. The other is a phone app, and the walk to the unit is short. The card worth reading twice is cycle life, because it is the one that can be entirely true and still not apply to you.

Scenario verdicts
We ran the math on seven 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 Yeti 500 comes up 1,676Wh short (about 20% covered), the Explorer 300 1,851Wh (12%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Neither of these is an eight-hour blackout plan. The 1,645Wh modelled here is nearly four times what the Yeti 500 holds usable and more than six times the Explorer 300's, so the Yeti covers about a quarter of the list and the Explorer about a seventh. What they are for in an outage is narrower and still worth having: the router, the phones, a lamp, the CPAP. Buy one of these as a lifeline rather than a plan, and if you want the whole eight hours, you want a station rated near the 1,645Wh the load actually asks for.
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
Yeti 500
At 40W for eight hours this needs 320Wh, and it is the one row on the page where these two units give different answers. The Yeti 500 has 424Wh usable, ends the night at 75% used, and keeps about two and a half hours of margin. The Explorer 300 has 249Wh, runs roughly six of the eight hours, and stops 71Wh short. If the thing plugged in is what keeps you breathing, 71Wh is not a percentage on a chart.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Neither unit
Neither unit covers this scenario's 910Wh: the Yeti 500 comes up 486Wh short (about 47% covered), the Explorer 300 661Wh (27%). Treat this as partial cover — enough for the essentials in it, not the whole list.
Battery budget usedlower = more headroom

SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Neither unit
The Explorer 300 can start the 400W peak but not hold it — 500W of surge gets it going, then the 300W continuous rating takes over, so capacity never gets a say. This is the wrong size of unit for the job rather than a close call. The Yeti 500 doesn't have the energy either — 424Wh usable against 670Wh, 246Wh short — so neither route works.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the Yeti 500 comes up 4,261Wh short (about 9% covered), the Explorer 300 4,436Wh (5%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

SCN-07 · an afternoon · needs 100Wh
Afternoon Off-Grid
Phones and a speaker at the park, beach, or campsite — the small-unit job description
Either unit
Both of these clear it without thinking: 100Wh of phones and a fan leaves the Yeti 500 at 24% used and the Explorer 300 at 40%. Nobody has ever cared about the difference between 324Wh spare and 149Wh spare on an afternoon. What you will care about is that one weighs 7.1 lbs and the other 16.1, and that the lighter one is also the cheaper one. On this row alone, the small box is the better buy and the leftover watt-hours are a rounding error.

Conclusion
September 19, 2026
Verdict: the Yeti 500, on Power Score margin
Take the Yeti 500. Of the seven loads modelled here, five defeat both units and one is trivial for both. The only row that separates them is a CPAP night, and the Yeti covers its 320Wh with 104Wh to spare while the Explorer 300 stops 71Wh short. Add a listed UPS mode rated no worse than 20ms, 1,000W of surge against 500W, and a pack rated for 4,000 cycles against 800, and what you are buying is a unit that can be left running rather than one that has to be attended. The confidence is a 7 and not a 9 because the Explorer 300 keeps one honest win: at 7.1 lbs and $211 less, it is the right answer for anyone whose real use is an afternoon with a phone, a speaker and a fan, and who will never once ask it to finish a night.

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 500 rates 4.5/5 (71st percentile of 25 Personal-class units), and Explorer 300 rates 3.7/5 (21st percentile of 25 Personal-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
No App on the Explorer 300, and Not Much Lost
The Explorer 300 has no app, so checking charge level means walking over to it. The Yeti 500 does have one, low-battery alerts included, and that is a genuine advantage if the unit lives in a basement or under a truck bed cover. Weigh it honestly, though. Goal Zero's app rates 4.4 out of 5 on iOS, with its recent ratings running below that on connectivity and stability; Jackery's sits between 2.3 and 3.3, the weakest of the major brands, split across two confusingly similar apps and demanding a login even offline. The Yeti wins this card. It wins it against a low bar.
Starting a Motor and Running One Are Different Specs
The Explorer 300 surges to 500W on a 300W continuous rating, which is 1.7 times. The Yeti 500 surges to 1,000W on 500W, a clean 2 times. Fridges, air conditioner compressors and power tools briefly pull 2 to 3 times their rated draw at startup, so the ratio tells you about the inverter while the absolute ceiling tells you whether one specific motor starts. The tailgate load shows the difference in action: the Explorer 300 gets a 400W draw moving on surge, then the 300W continuous rating takes over and it cannot hold it. Check the startup figure printed on the heaviest thing you plan to run against 500W and against 1,000W before assuming either is enough.
Only the Yeti 500 Can Be Left Plugged In
The Yeti 500 lists a UPS mode: it sits between the wall and your gear and hands over to battery when the grid drops, rated no worse than 20ms. Read that as a published ceiling rather than a measured switchover time. It is fine on paper for a router, a desktop or a CPAP, though the fussiest PC power supplies sit right on that line. The Explorer 300's spec sheet lists no UPS mode at all, which means anything plugged into it rides out a blackout only as long as it takes you to notice and re-plug. For a machine that runs while you sleep, that is the whole difference between owning a battery and owning a backup.
Warranty: 5 Years vs 2
The Yeti 500 is covered for 5 years against the Explorer 300's 2 years. An underrated factor if you're keeping this unit for years.
4,000 Cycles Against 800, and When That Stops Mattering
The Yeti 500 is rated for 4,000 cycles and the Explorer 300 for 800, and because a Yeti cycle moves 499Wh against 293Wh, the lifetime energy gap is wider than the cycle counts suggest: roughly 1,996 kWh against 234. Neither battery dies at the limit. Both settle to about 80% of original capacity and keep working. Here is the honest part, and it cuts against the bigger unit. A cycle rating is only spent by cycling. At daily use the Explorer 300 runs 2.2 years and the Yeti 500 eleven; at twice a week, 7.7 years against 38.5. If your unit comes out of a closet three times a summer, the numbers on this card are the least important thing on the page.
Yeti 500: Noise Level Not Disclosed
The Explorer 300 publishes its noise level (36dB); the Yeti 500 doesn't publish one. That isn't evidence the Yeti 500 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 Explorer 300's 36dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the Yeti 500 before deciding.

Brand trust
Goal Zero
Ecosystem
A deliberately small line: the 6th-generation Yeti and Yeti Pro series, Sherpa power banks below 100Wh, Nomad and Ranger panels, Alta coolers and vehicle integration kits. The previous-generation X series has cleared out of Goal Zero's own store, so cross-shopping a 500X now means hunting retailer leftovers rather than the current catalogue. The Yeti 500 on this page is the current LiFePO4 unit, not one of those.
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
Goal Zero usually asks the most per watt-hour of the major brands and it does again on this sticker, though across 4,000 rated cycles the arithmetic reverses and this is the cheaper energy of the two. The real warning is service. Support has slipped well below the premium standard the pricing was built on, with long waits and email that goes unanswered, and the official community forums have been shuttered. The warranty term is 5 years; budget for the possibility that using it is slow.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
Support
US-based support but widely criticized. Reddit reports describe slow/dismissive responses, scripted AI agents, strict receipt requirements for warranty claims, and refurbished replacements for clearly defective units. Strongly recommended: buy from Costco or Amazon for return protection.
Community
Smallest community of the major brands — Reddit r/Jackery has ~2,000 members. YouTube presence is solid due to brand recognition.
App experience
Rated 2.3-3.3/5 iOS and Android — the weakest app experience of the major brands. Multiple confusing apps (Jackery app vs Jackery Home) and mandatory login even offline.
Unique strength
Highest brand recognition and widest retail distribution (Costco, Home Depot, Best Buy, Amazon). The "Toyota" of power stations — dependable, proven, wide availability. Innovative form factors like the Solar Gazebo and Solar Mars Bot.
Worth knowing
The general warning on Jackery's record lands directly on this model. A couple of older units still ship the older chemistry with a shorter rated life, and the base Explorer 300 is one of them at 800 cycles while most of the current line has moved to LiFePO4. The usual Jackery advice applies too: buy from a retailer with a real returns desk, because warranty claims run through a support operation that is strict about receipts and has sent refurbished replacements for defective units.
Analyst note
Two US-facing brands with the same weak spot, which is that neither support operation is a reason to buy. Goal Zero's has fallen away from the premium standard its prices imply; Jackery's is the one buyers route around by purchasing at Costco or Amazon so there is a returns desk standing between them and it. Brand character is not what decides this page. What decides it is that Goal Zero put LiFePO4 in this unit and Jackery did not put it in that one.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Goal Zero Yeti 500
Field evidence on the Yeti 500 is thinA0, and the first thing worth saying about it is a warning rather than a finding. Listings routinely conflate this LFP unit with the older NMC Yeti 500X, which was rated around 500 cycles rather than 4,000A0A3. If a review you are reading describes a Yeti 500 that faded fast, check which one it actually tested.
What exists past that is the published rating plus one long-term check. Goal Zero rates the pack at 4,000-plus cycles and frames that as over ten years of daily use to 80% capacity at 75FA1, and one 2026 reviewer put 180-plus charge and discharge cycles through a unit with minimal observed degradationA4. That is real evidence and it is also under 5% of the rated life, so it says nothing about year eight. Goal Zero's own backup copy claims a full-size refrigerator for up to six hoursA2; treat that as a maker claim rather than a measurement, and check it against the label on your own fridge before you lean on it.
“The Yeti 500's LiFePO4 battery is rated for 4,000+ cycles, meaning daily use for over 10 years (to 80% capacity at 75F).”

Jackery Explorer 300
Owners who stay inside the Explorer 300's size report exactly what you would hopeB3B4. One ran phones, a speaker, a fan and an air mattress through a camping trip and called it easy, light and quietB3. Another recharged small electronics daily and went about two weeks before the charge got lowB4. Nothing in the record contradicts that, and nothing in it pushes the unit anywhere near its 300W ceiling.
One caution before you go reading reviews. A great deal of what is written about the Explorer 300 is actually about the Explorer 300 Plus, which is a different box: LiFePO4 chemistry, 3,000 cycles, 8.27 lbsB0. The unit on this page is the base Explorer 300, 293Wh of lithium-ion at 7.1 lbs and 800 cycles, verified against Jackery's own listingB0. Two of the four entries in our ledger turned out to describe the Plus, so they are set aside here rather than citedB0.
“288Wh capacity with 300W output on LiFePO4 chemistry rated for 3,000+ cycles — over a decade of daily use, a major upgrade from the older lithium-ion Explorer 300 (500 cycles).”

Who Should Buy Which
Buy the Yeti 500 if you…
- →Something you own has to run while you are asleep. The Yeti 500 covers the 320Wh CPAP night with 104Wh in hand, and the listed UPS mode rated no worse than 20ms means a grid drop does not interrupt it on the way.
- →You will genuinely cycle this thing. At twice a week the 4,000-cycle rating runs 38.5 years, so you will replace it out of boredom rather than wear.
- →A working laptop rides in the same bag. Two USB-C ports at 100W against one at 60W is two-thirds more charging speed and a second outlet, so the phone is not queued behind the laptop.
- →You want the larger ceiling and accept that it is fixed. Neither unit expands, so 499Wh is the number you live with for as long as you own it.
Buy the Explorer 300 if you…
- →The honest job is an afternoon. 100Wh of phones, a speaker and a fan leaves the Explorer 300 at 40% used, and everything the Yeti 500 has left over that day goes unspent.
- →You carry it more than you run it. 7.1 lbs goes into a daypack without a conversation; 16.1 lbs is a load you set down when you get there.
- →It comes out a few times a year. 800 cycles is 7.7 years even at twice a week, so at a handful of trips a summer the cycle rating is not what ends this unit, and you keep $211.
If neither fits
If your list looks like a weekend of camping at 2,100Wh, an eight-hour blackout at 1,645Wh or a day in a van at 4,685Wh, close this tab. Against 424Wh and 249Wh usable those are not near-misses, they are the wrong class of product. Shop 1,000Wh and up, look for a real UPS mode and an expansion port while you are there, and come back to these two only if you decide you wanted a second, smaller unit all along.
The Bottom Line
Buy the Yeti 500. Five of the seven loads on this page defeat both units and one is easy for both, so the whole comparison rests on the single row where they disagree, and on that row the Yeti finishes the night with 104Wh in hand while the Explorer 300 stops roughly two hours early. Everything else stacks the same direction: 1,000W of surge against 500W, a listed UPS mode against none, 4,000 rated cycles against 800.
The Explorer 300 keeps one clean win and it deserves saying out loud. At 7.1 lbs and $211 less, it is the better box for the person whose real use is an afternoon with a phone, a speaker and a fan, and who is never going to ask it to run past bedtime. If that is you, take the light one with a clear conscience. If you had to think about it for more than a second, you are the Yeti buyer. Go get it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Will a Jackery Explorer 300 run a CPAP all night?
Not a full night at 40W. The Explorer 300's 293Wh derates to 249Wh usable, which is about six hours, while the eight-hour night modelled here needs 320Wh. It finishes 71Wh short. The Yeti 500 covers the same night with 104Wh left over, so if the machine has to run until morning, that is the unit to buy.
Is the Goal Zero Yeti 500 the same thing as the Yeti 500X?
No, and it is the most common mix-up on this model. The 500X is the older NMC unit rated around 500 cycles; the Yeti 500 on this page is the LiFePO4 version rated for 4,000-plus, and listings conflate the two. If a review describes a Yeti 500 that lost capacity quickly, check which one it tested before you let it decide anything.
Is the Yeti 500 worth $211 more than the Explorer 300?
If you cycle it, yes, and it is not close. Over their rated lives the Yeti 500 holds about 1,996 kWh of energy against the Explorer 300's 234, which works out to 25 cents a lifetime kilowatt-hour against a dollar ten. If the unit instead lives in a closet and comes out a few weekends a year, you will never reach those numbers, and the lighter, cheaper box is the sensible buy.
Which of these is better for a power outage?
The Yeti 500, on two counts: it is the only one of the pair listing a UPS mode, rated no worse than 20ms, and it has 424Wh usable against 249Wh. Set expectations, though. The eight-hour blackout modelled here needs 1,645Wh, and the Yeti 500 is 1,221Wh short of that while the Explorer 300 is 1,396Wh short. Either one is a lifeline for a router, some phones and a CPAP, not a plan for the house.
Can either of these run a refrigerator?
Briefly, and only the Yeti 500 with any margin. Goal Zero's own backup copy claims a full-size refrigerator for up to six hours on the Yeti 500, which is a maker claim rather than a measurement. Mechanically, the Yeti 500's 1,000W surge clears the 2x cushion motor startups want, while the Explorer 300 tops out at 500W, so check the startup draw on your fridge's label against that figure. At 424Wh and 249Wh usable, neither is a multi-day fridge plan.
