Goal Zero Yeti 3000X vs Goal Zero Yeti PRO 4000
The Yeti 3000X has left Goal Zero's range, and the PRO 4000 is where Goal Zero points its owners. The question is what moving up buys, and what the extra 46 pounds cost.

Spec deltas
Goal Zero no longer sells the Yeti 3000X. Its closest current model is the Yeti PRO 4000. So this page is for two people. One owns a 3000X and wonders whether to move up. The other has found one for sale secondhand and wants to know what they'd be missing.
On paper the PRO 4000 is bigger in nearly every column. It holds 3,994Wh to the 3000X's 3,032. Its inverter runs 3,600W continuous, so it can carry more at once. It also lists a UPS mode, which means it can sit between the wall and your gear and take over when the grid drops. The 3000X lists none.
The difference I'd weigh first is the battery. The 3000X uses NMC, an older lithium chemistry, and it's rated for 500 full cycles. The PRO 4000 is rated for 4,000. Storms take my canyon off the grid often enough that a pack with few cycles left is a pack I'd end up buying twice.
Then there's the weight. The PRO 4000 is 115.7 lbs, which is roughly what my first backup battery weighed when I wheeled it down the driveway during the CZU fires. I would not call it portable, and neither do owners. They call it a two-person liftB1.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
rated cycles
A cycle is one full drain and refill. Used every weekend, the 3000X's rating runs out in under five years. The PRO 4000's runs for decades on paper.
The Yeti PRO 4000 is rated for 4,000 cycles against the Yeti 3000X's 500Rated lifetime energy works out to about 15,976 kWh against 1,516 kWhThe PRO 4000 carries a 5-year warranty against the 3000X's 2
Why it mattersFor anyone who cycles a station often, the PRO 4000 works out to $0.25 per lifetime kWh. The 3000X gets no price on this page, because it's no longer sold.
One owner returned a unit, and the replacement then threw a 12V error and would not charge from solarB3. That's a small number of owners. It's the kind of fault you want to find in the first week.
Owner reports describe mixed reliability on the Yeti PRO 4000, including 12V errors on at least two units, one of them a replacement that also would not charge from solarB3The PRO 4000's 3,000W solar input and durable build are otherwise praisedB1B2
Why it mattersBuy from a seller with an easy return, and run a solar charge and the 12V port in the first few days.
Both numbers use a flat 15% allowance for conversion losses, so they describe usable energy rather than the label. More battery gets you closer. It doesn't finish the day.
The Yeti PRO 4000 weighs 115.7 lbs against the 3000X's 69.78 lbsVan Life Daily needs 4,685Wh; the PRO 4000 covers about 72% of it and the 3000X about 55%
Why it mattersA van build running off either one needs solar topping it up during the day. The PRO 4000's 3,000W input is the one that can keep pace.
solar input
That's the scenario I live with in the canyon. If I were wiring one of these into my transfer switch, I'd want the PRO 4000, for the UPS mode on the Starlink and the desktop and for the solar input on the grey days after a storm.
On the 8-Hour Blackout the PRO 4000 finishes with 1,750Wh left against the 3000X's 932WhOnly the PRO 4000 lists a UPS mode, rated at no worse than 15msSolar input is 3,000W against 600W
Why it mattersFor outages that run past one night, the PRO 4000 is the better tool, as long as the reliability reports and the lift don't rule it out for you.
The specific dimensions that decide these two units β everything else is a tie.
Lifetime Value
Selected because: Eight times the rated cycles is what separates these two over years of use.
A cycle rating is how many full drains and refills a pack gets before it drops to about 80% of new. The 3000X's NMC pack is rated for 500, and reviewers call that its biggest drawbackA1. The PRO 4000 is rated for 4,000.
Count it as energy and the gap stays wide. The 3000X's rated life adds up to about 1,516 kWh. The PRO 4000's adds up to about 15,976 kWh, which puts it at $0.25 per lifetime kWh at today's price. The 3000X shows no price here, since it's no longer sold.
If you already own a 3000X and run it a few times a year, those 500 cycles may never run out. That's a fair reason to keep it.
Your Life, Your Pick
Selected because: The 3000X takes the trips you'd carry it on; the PRO 4000 takes the long outage.
The engine gives Weekend Camping and the Tailgate Party to the 3000X, and the reason is weight. A 115.7 lb station rolls off a truck bed if it travels at all. Both have the battery for those trips.
The 8-Hour Blackout goes to the PRO 4000. Both finish, but it has roughly another night left. A CPAP night and a remote workday are easy for both. Van Life Daily is beyond both, though the PRO 4000 gets about 72% of the way.
Portability & Form Factor
Selected because: About 46 lbs is the price of the PRO 4000's extra battery, and owners call it a two-person lift.
weight
The 3000X is about 70 lbs and ships with a roll cart, which owners say you'll needA2. The PRO 4000 is 115.7 lbs, and owners describe it as a two-person unitB1.
If I bought one, it would live beside the transfer switch and never move. If yours has to reach a campsite or a job site with one person, the weight settles this before anything else gets a vote.
What the Specs Don't Tell You
Selected because: Only the PRO 4000 lists a UPS mode, and this is where the owner reliability reports belong.
rated cycles
Only the PRO 4000 lists a UPS mode, rated at no worse than 15ms. Goal Zero states it as a ceiling, and nobody has timed it. It's fine on paper for routers and most electronics, and the fussiest desktop power supplies sit near that line. The 3000X lists no UPS mode, so anything plugged into it rides an outage only as far as your reaction time.
The other thing to know about the PRO 4000 isn't on the spec sheet. Some owners report 12V errors, and one replacement unit also refused to charge from solarB3. Register it, plug in a panel and use the 12V port in the first week. If either misbehaves, you're still inside the easy part of a return.

Weekend Camping
Two nights off-grid with essential comfort
Yeti 3000X
Both have the battery for a two-night trip, and the 3000X finishes with 477Wh to spare. The engine gives it the scenario because it's the one you can realistically take. The PRO 4000 would arrive with more left, if you could get it out of the truck.

8-Hour Blackout
Keep the essentials running through a night without power
Yeti PRO 4000
Both survive the night. The Yeti PRO 4000 finishes at 48% used with 1,750Wh left β 1.1 more nights like it. The Yeti 3000X finishes at 64% with 932Wh, 57% of a second night. If your outages tend to run past one evening, that difference is the whole argument between them.

CPAP Overnight
Sleep therapy without interruption β the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both of these cover the night several times over β capacity isn't the question here. What would separate them is fan noise, but neither maker publishes a fan-noise figure, so there's nothing to hold either of them to. Only the Yeti PRO 4000 is still sold, so for a new buy it takes this by default; the Yeti 3000X is worth weighing on weight and fan noise only if you already own one.

Either unit
Both power your workstation all day without strain. At these utilization levels the real difference is USB-C for direct laptop charging β 100W on the Yeti PRO 4000 against 60W β which beats the inverter for convenience and wastes less energy.

Yeti 3000X
The Yeti PRO 4000 at 115.7 lbs is not a take-along β it rolls off a truck bed if it travels at all, so this scenario belongs to the Yeti 3000X by default β and it earns it, covering the 670Wh with 1,907Wh to spare. Capacity was never the Yeti PRO 4000's problem here; getting to a tailgate was.

Conclusion
October 25, 2026
Verdict: the Yeti PRO 4000, on Power Score margin
The Yeti 3000X has left Goal Zero's range, so the PRO 4000 is the only one of these you can buy new, and it earns the spot on its own. Its pack is rated for 4,000 cycles against the 3000X's 500. It adds a UPS mode rated at no worse than 15ms, a far bigger solar input and a 5-year warranty against 2. The catches are real. At 115.7 lbs owners call it a two-person liftB1, and some owners report 12V errors, including a replacement unit that still would not charge from solarB3. Test the solar input and the 12V port in the first week, while the return is still easy.

Each unit's star score is a category ranking, not customer reviews β 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 5β . Here, Yeti 3000X rates 3.3/5 (1st percentile of 28 Large-class units), and Yeti PRO 4000 rates 3.6/5 (16th percentile of 20 Home Backup-class units).

Weight Reality Check
Neither unit is grab-and-go. The Yeti 3000X (69.8 lbs) is manageable solo but heavier than a large checked suitcase. The Yeti PRO 4000 (115.7 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 46 lb difference, and it is paid once β getting the heavier one into position, not every time you move it.

The Yeti PRO 4000 can sit between the wall and your gear and hand it to battery when the grid drops β rated β€15ms β 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 3000X's spec sheet lists no UPS mode, so anything plugged into it rides an outage only as far as your reaction time.
Warranty: 5 Years vs 2
The Yeti PRO 4000 is covered for 5 years against the Yeti 3000X's 2 years. An underrated factor if you're keeping this unit for years.
Eight Times the Cycles
The PRO 4000 is rated for 4,000 cycles against the 3000X's 500. Counted as energy, that's about 15,976 kWh over its rated life against 1,516 kWh. When the rating runs out, a pack doesn't die. It holds about 80% of what it did new.

Analyst note
The Yeti 3000X is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the Yeti PRO 4000 works out at $0.25/kWh over its rated life. If you already own the Yeti 3000X, the hardware comparison still holds: over its rated life the Yeti 3000X delivers about 1,516 kWh and the Yeti PRO 4000 about 15,976 kWh.

Analyst note
Growth only counts if you can still buy in, and the Yeti 3000X is no longer sold, replaced by the Yeti PRO 4000 beside it. That leaves the Yeti PRO 4000: it starts at 3,994Wh and takes Goal Zero expansion batteries, so the ceiling moves if your needs do. The Yeti 3000X's expandability still matters if you already own one, but it isn't a reason to pick it over the Yeti PRO 4000.
What Owners Report
Patterns from published owner reports and long-term reviews β every claim cited to its source below.
Goal Zero Yeti 3000X
Reviewers confirm the Yeti 3000X's core numbers: 3,032Wh, a 2,000W inverter and a 3,500W surgeA3. The complaint that follows it is the battery. Its NMC pack is rated for 500 cycles, and reviewers call that its biggest drawback next to LiFePO4 stations clearing 3,000-plusA1.
Weight comes up too. It's a roughly 70-pound unit that comes with a roll cart, and owners say the cart is essentialA2. Expansion runs through Goal Zero's Tank batteries, which are lead-acid. Reviewers report only about half their capacity is usable, and that connecting one halves the onboard lithium capacityA4.

Goal Zero Yeti PRO 4000
The PRO 4000's 3,000W solar input gets the most praise. Reviewers report a full recharge from empty in under two hours off-grid, with strong surge handling and good idle efficiencyB2. It's described as one of the most durable builds reviewers have handled, with American-based support and a well-liked appB1, and it's praised for RV and camping backup at roughly 3,994WhB4.
The complaints are weight and reliability. At about 115.7 lbs it's a two-person unitB1. Some owners report 12V errors, including one whose first unit was returned and whose second had a 12V error and would not charge from solarB3.

Who Should Buy Which
Buy the Yeti 3000X if youβ¦
- βYou already own one and use it a handful of times a year. At that pace its 500 cycles may never run out, so there's little reason to replace it.
- βYou move it alone. At about 70 lbs with a roll cartA2, it's the one of these one person can get into a truck.
Buy the Yeti PRO 4000 if youβ¦
- βYou're planning for outages that run past one night, and you want a UPS mode for a router, a Starlink or a desktop.
- βYou'll cycle it often, from solar or regular outages, so the 4,000-cycle rating gets used.
- βIt can stay in one place. At 115.7 lbs it's a two-person liftB1.
If neither fits
Full-time van power wants 4,685Wh a day, and neither covers it. The PRO 4000 gets about 72% of the way, so a daily-use build needs solar topping it up during the day or a larger modular system.
The Bottom Line
The Yeti 3000X has left Goal Zero's range. The PRO 4000 that replaces it is rated for eight times the cycles, adds a UPS mode, and takes five times the solar input.
It asks two things of you. Find a second person for the liftB1. Then test the solar input and the 12V port in the first week, given the owner reportsB3. If you already own a 3000X and use it lightly, it still does what it always did.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Goal Zero Yeti 3000X still sold?
No. Goal Zero no longer sells the Yeti 3000X. The closest current model is the Yeti PRO 4000, a larger LiFePO4 station.
What does the Yeti PRO 4000 add over the 3000X?
A pack rated for 4,000 cycles against 500, a 5-year warranty against 2, a UPS mode rated at no worse than 15ms, a 3,600W inverter against 2,000W, and 3,000W of solar input against 600W. It also weighs 115.7 lbs against 69.78 lbs.
Is the Yeti PRO 4000 reliable?
Mostly, with a caveat. Owner reports describe 12V charging errors on individual units, including one case where a replacement unit also failed to charge from solar. Build quality and support are otherwise praised. Register the unit and test solar charging early.
How much heavier is the PRO 4000?
45.92 lbs heavier: 115.7 lbs against the 3000X's 69.78 lbs. Owners describe the PRO 4000 as a two-person lift, while the 3000X ships with a roll cart.
Can either handle full-time van life power?
No. Van Life Daily needs 4,685Wh. After a flat 15% allowance for conversion losses, the PRO 4000 covers about 72% of it and the 3000X about 55%.
Which should I buy?
The Yeti PRO 4000, since it's the one still sold. Plan for a two-person lift and test solar charging early given the owner reports. If you already own a 3000X and use it lightly, keeping it is reasonable.
