How these were chosen
We have tested none of this equipment, and our methodology page says so in detail. Everything below is Goal Zero's published specification for that model, the equivalent published figure for the units it competes with, or arithmetic we show.
Three criteria decided the picks, in this order:
- Is it currently purchasable? Two of the most-searched Goal Zero model numbers are not, which is covered in the next section.
- Does the inverter match the capacity? A big battery behind a small inverter runs fewer things, and Goal Zero's smaller models are conservative here.
- Does the premium buy something you can name? IPX4, aluminum, 4,000+ cycles, a five-year warranty and a 900W solar ceiling are all real. Brand reputation on its own is not.
First, the models people search for that you cannot buy
Goal Zero replaced its X-series with a 6th-generation Yeti line, and search results have not caught up. Three specific cases matter:
- Yeti 300. Goal Zero still lists it in the 6th-generation line, but it is no longer available through Amazon, so it has no buy link on this site. It stays in the tables below for comparison because the specifications are real and people still search for them. If 297Wh is the size you want, the Yeti 700 is the smallest Goal Zero you can actually buy today.
- Yeti 1500X. Still one of the most searched Goal Zero terms, and at the time of writing it is listed on Amazon as currently unavailable. The current equivalent is the Yeti 1500 in this roundup, which is a different machine with LiFePO4 cells rather than the X-series lithium NMC.
- Yeti 400 and the older numbered units. Long discontinued. Any listing you find is old stock or third-party resale, and the warranty question alone makes that a poor purchase.
We do not feature products we cannot confirm as purchasable. If you arrived here looking for a 1500X, the Yeti 1500 is the model that replaced it and the specifications below are the current ones.
The current lineup, side by side
| Model | Capacity | AC output | Weight | AC recharge | Max solar |
|---|
| Yeti 300 (not currently available) | 297 Wh | 350 W / 600 W surge | 13.7 lb | 50 min fast, 3 h default | 200 W |
|---|
| Yeti 700 | 677 Wh | 600 W / 1,000 W surge | 20.3 lb | 1.7 h at 500 W | 200 W |
|---|
| Yeti 1500 | 1,505 Wh | 2,000 W / 3,600 W surge | 52.75 lb | 0.8 h to 80%, 1.1 h full | 900 W |
|---|
Every figure is Goal Zero's own published specification from the product pages linked at the foot of this page. All three are LiFePO4, all three are rated IPX4, all three carry a five-year warranty and a 4,000+ cycle rating.
Read across the AC output column and the shape of the range becomes obvious. The jump from the 700 to the 1500 is not really about capacity — it is 600W to 2,000W of inverter, which is the difference between charging things and running a household.
What the premium actually buys
Goal Zero costs more per watt-hour than the brands this site covers most often. Four published specifications explain where that money goes, and it is worth being precise about which of them you will ever use.
| What you pay for | The specification | Who actually needs it |
|---|
| Weather resistance | IPX4 across the range | Anyone using it on a truck bed, a boat, a job site or an exposed campsite |
|---|
| Cell longevity | 4,000+ cycles to 80% | Daily cyclers — vans, cabins, off-grid. Storm households will never reach it |
|---|
| Solar ceiling (1500 only) | 900 W across dual inputs | Anyone charging from panels rather than from a wall socket |
|---|
| Warranty | 5 years | Everyone, and it is genuinely longer than most |
|---|
Specifications are Goal Zero's published figures. The right-hand column is our judgment, not theirs.
The honest summary: if the battery lives indoors and gets used three times a year, you are paying for protection you will never use. If it lives outdoors, gets rained on, and cycles weekly, the premium is defensible and the warranty makes it more so.
Goal Zero against the cheaper alternatives
This is the comparison the brand does not make, so here it is on published numbers.
| Unit | Capacity | Continuous output | Cycles | Weather rating |
|---|
| Goal Zero Yeti 1500 | 1,505 Wh | 2,000 W | 4,000 | IPX4 |
|---|
| BLUETTI Elite 200 V2 | 2,073.6 Wh | 2,600 W | 6,000+ | None published |
|---|
| EcoFlow DELTA 2 Max | 2,048 Wh | 2,400 W | 3,000+ | None published |
|---|
| Goal Zero Yeti 700 | 677 Wh | 600 W | 4,000+ | IPX4 |
|---|
| Anker SOLIX C1000 | 1,056 Wh | 1,800 W | 3,000 | None published |
|---|
Manufacturer figures from the pages cited below. "None published" means the maker states no ingress rating on the page we cite — not that the unit is fragile, only that nobody has promised anything.
On capacity and output per dollar, Goal Zero loses to every rival in that table. On protection, cycle rating and warranty, it wins. That is the trade in one sentence, and neither side of it is marketing.
What each one runs, and for how long
Planning at 85% inverter efficiency, which is the figure used across this site.
| Load | Yeti 300 (297 Wh, discontinued) | Yeti 700 (677 Wh) | Yeti 1500 (1,505 Wh) |
|---|
| CPAP, no humidifier (40 W) | About 6 hours | About 14 hours | About 32 hours |
|---|
| Router, modem, laptop (75 W) | About 3.4 hours | About 7.7 hours | About 17 hours |
|---|
| Refrigerator (150 W average) | Not enough surge headroom | Marginal — 1,000 W surge | About 8.5 hours |
|---|
| Two LED lamps and phones (25 W) | About 10 hours | About 23 hours | Over two days |
|---|
Runtime is capacity x 0.85 divided by average draw. A refrigerator compressor can demand 600 to 1,200W at the instant it starts, which is why the 700's 1,000W surge is marked marginal — starting watts vs running watts explains the distinction.
Which one, for which buyer
- Storm backup for a house: the Yeti 1500, or a cheaper 2kWh rival if the unit never leaves the utility room. Compare against the 2000Wh roundup before deciding.
- Camping, overlanding, a boat: the Yeti 700. The IPX4 rating and 20 lb carry weight are worth real money here in a way they are not indoors.
- Phones, a CPAP and lights: the Yeti 700 is the smallest Goal Zero still on sale, or the smaller units in the 500Wh roundup if weather protection is irrelevant to you.
- Maximum capacity per dollar: not Goal Zero. That is what Anker and Jackery compete on, and they win it.
The short version
- Two models you can buy: Yeti 700 (677Wh) and Yeti 1500 (1,505Wh). Both LiFePO4, both IPX4, both five-year warranty. The Yeti 300 is no longer available through Amazon.
- The 1500 is the one that backs up a house — 2,000W of inverter and a 900W solar ceiling no rival here matches.
- The 700 is the one to take outdoors. Twenty pounds and a published water rating.
- You pay a premium per watt-hour. It buys protection, cycle life and warranty — not capacity or output.
- The Yeti 1500X is gone. If that is what you searched for, the Yeti 1500 replaced it.
