Goal Zero Yeti 400 Review
400Wh of storage, 120W continuous output, Lead-acid cells. Listed at $449.95 at Goal Zero.
The Goal Zero Yeti 400 is a portable under 600wh unit holding 400Wh. At $1.12 per watt-hour it is priced above the median for the band, so you are paying a premium over comparable capacity. Cells are Lead-acid. This model is discontinued, so stock is whatever is left in the channel.

What the Goal Zero Yeti 400 will run, and for how long
Runtimes below are calculated from the 400Wh rated capacity, derated to 85% for AC loads and 92% for USB and 12V loads to cover inverter and conversion losses. They are arithmetic, not lab measurements, but they are the same arithmetic applied to every unit we track, so the comparison holds. Anything drawing more than the 120W continuous rating is left off the list because this unit cannot carry it.
| Load | Estimated runtime |
|---|---|
| Phone charge (12Wh) | 30 charges |
| Wi-Fi router (10W) | 34 hr |
| LED work light (10W) | 37 hr |
| CPAP, humidifier off (40W) | 8 hr 30 min |
| Laptop (60W) | 5 hr 40 min |
| 12V portable fridge (45W avg) | 7 hr 33 min |
| 55-inch TV (90W) | 3 hr 47 min |
Real figures land below these. A fridge cycles rather than drawing continuously, and cold weather costs a lithium pack usable capacity, so treat the table as the ceiling rather than the expectation.

Where the Goal Zero Yeti 400 sits in its band
We track 36 units in the portable under 600wh band with both a price and a published capacity. They run from $118 to $599.95, and from 128Wh to 576Wh. On cost per watt-hour the Goal Zero Yeti 400 ranks 26 of 36, where 1 is the cheapest capacity in the band. That puts it in the most expensive third, so it has to earn the difference somewhere other than raw capacity. Ranking on cost per watt-hour deliberately ignores build quality, port selection and warranty, so read it as one input rather than as the answer.
Alternatives to the Goal Zero Yeti 400
Units we track in the same band that are close enough to be genuine substitutes, matched on capacity. Each links to its own review.

Who the Goal Zero Yeti 400 suits
It is a sensible buy for weekend camping, a CPAP overnight, phones and laptops, and keeping a router alive through a short outage. It is the wrong tool for anything with a heating element, and any attempt to run a fridge for more than a day.
Goal Zero Yeti 400 questions
How long will the Goal Zero Yeti 400 run a fridge?
A full-size fridge averages about 50W once you account for the compressor cycling on and off. From 400Wh, derated to 85% for inverter losses, that is roughly 6 hr 48 min on a full charge. A 12V portable fridge draws less and will run considerably longer.
Can the Goal Zero Yeti 400 be charged by solar?
Goal Zero does not publish a maximum solar input for this model. Rather than estimate one, we leave it out. Check the manual that ships with the unit before buying panels for it.
Is the Goal Zero Yeti 400 worth it?
At $449.95 it works out at $1.12 per watt-hour. It costs more per watt-hour than the median unit in its band, so the case for it rests on the features rather than on the price. Read the comparison table above against the two closest rivals before deciding.
What is not published
Goal Zero does not state the rated cycle life, the maximum solar input, the warranty term for this model. We list figures rather than estimate them, so those rows stay empty until the manufacturer publishes them. If you need one of them to make the decision, ask Goal Zero directly and hold them to the answer.
How we assess these
Every figure on this page comes from the manufacturer, and every derived number, cost per watt-hour and estimated runtime, is calculated the same way for all 437 products we track. That is what makes the comparison meaningful: we are not scoring units against a private impression of them, we are putting published figures side by side and doing the arithmetic in public. Where a manufacturer stays quiet, we say so rather than filling the gap.
