Rated 5 out of 5 by from Excellent gear for power in the field My company acquired this generator to use in the field for video production. We do documentary film work in a multitude of locations and having a compact, portable power source like the Yeti 400 is a lifesaver. It easily powered our large LED light panels and left ample power available for other devices like battery and phone chargers. It's really nice to not even have to think about power solutions when you arrive to a location to film, and allows us to be more efficient with our setups, which is key to staying on schedule when we're trying to pack in a full day of shooting. Just a fantastic piece of gear that we quickly came to rely on.

Rated 1 out of 5 by from Yeti died within first year I bought my Yeti and was very excited about using it. Bought a package with the solar panels and original lights. Never really got to use it camping but kept it charged for almost a year. I really only took it out to show it off to people. Then, after building a tree house for my kids, I thought it would be an awesome opportunity to use the Yeti on a regular basis. The only problem? It died after a couple days of use. I went through the customer service email but they said they couldn't help me because it was past the year warranty. Now it's just a very large (and very heavy) paper weight. I was a big brand loyalist for Goal Zero... Very disappointed!

Rated 5 out of 5 by from I have sleep apnea and my Yeti 400 has been a great backup power source for my CPAP on several occasions when storms took out our power in the middle of the night. Also I have used my Yeti 400 when we have had thunderstorms since I was afraid lightening might damage my expensive CPAP. I lost numerous appliances years ago when lightening struck my house and "fried" the appliances that had power from our local power company. Today my CPAP is so much safer in a thunderstorm when it is just being powered by my Yeti 400. I sleep better during storms because of Goal Zero.

Rated 5 out of 5 by from Yeti 400 is great I upgraded to a Yeti 400 from a 150. I have chained 4 - Duracell 35 amp hour batteries, totaling 2,000 watts/175 amp hours. I can watch a 50" Samsung LED HD TV with satellite dish for several hours and run an ARP cooler through the inverter with no problems. I also have several Goal Zero products that stay fully charged, as well as cell phones, tablets and an occasional lap top. I would have purchased the 1250, but no room, the 400 is doing a great job staying charged with a Renogy 100 watt mono solar panel.

Rated 5 out of 5 by from Excellent work horse for cross state trip I am so glad that I selected the yeti 400 to power my CPAP and other electrical equipment while on a seven day cross Texas trip. My main reason for selecting the yeti 400 was its features and ability to be charged by my vehicles 12 volt lighter connection while on the road, solar panels in isolated locations, and motel room outlets during overnight stays. The yeti 400 is about the size of a vehicle battery and still light enough to be carried without any difficulties. Being disabled, I have no problems in its operations Thanks for a well designed product.

Rated 4 out of 5 by from Fantastic performance We used this battery for a two week camping trip and it was a workhorse. Not only did we run our camp lighting off of it and recharged a plethora of smart phones and other tech, but it easily ran airbed pumps, cooking tools and a sewing machine. The display screen in particular with it's input and outut data was a huge improvement and definitely our favorite update compared to the escape 150. The only downside is that it does take a bit to charge, we were comfortably charging it with 2x 30w solar panels, only using one did feel perilously slow on it's own.

Rated 3 out of 5 by from Escape 150 I have literally bought about $10k in Goal Zero products in the past three years and have had pretty good success. The only product I've had problems with is the Escape 150. I had bought two of these and had problems with both of them. The problem I had was that the batteries would drain down in five days without any draw on them. I called Goal Zero but could not get any support to replace them. At the time, these units were less than 6 months old. Goal Zero has a real problem with this produce and would not make it right with me, even though I have bought 6 Yeti 1250's, dozens of Boulder 15's and 30's, two Yeti 400's, 20 Light a Life's, and ton's of other smaller products.

Rated 5 out of 5 by from Supported 4 adults for 10 days at the Jamboree I bought this kit so that myself and 3 other adults of our Boy Scout Jamboree troop could charge our phones and laptops at our campsite during the national jamboree. It did that and supported several desperate scouts with an emergency charge. After a cloudy day I did have to carry up to the adult lounge and plug it in for a few hours, but overall it worked very well. The second last day the built-in inverter blew a fuse or something but once I got home they cheerfully exchanged it for me. I also want to add that I did have a scout goofing off trip over and rip apart the panel to Yeti cable. As luck would have it Goal Zero had a booth at the Jamboree and once I told them my story the Goal Zero employee returned with a replacement cable free of charge. Seems like a great company that really believes and supports their product.

For those using this to power a cPap, how long is this lasting you on a full charge?  I recognize it can vary by machine and settings. My Yeti 150 only gets me through maybe 4-6 hours even when I'm not running a humidifier. Thank you. 

Asked by: junkyburrittos
I just bought a Yeti for for the the purpose of being able to use a BiPap (similar to CPAP) machine at a remote off grid cabin.  I am pleased to say I got four nights of use before the battery reached 40%.  The first night didn't budge the meter - it stayed at 100%.  the second brought it down to 80%, the third to 60% and the fourth to 40%... time to recharge.  I have a humidifier, but it's set at its lowest setting. I used the AC adaptor.  I sleep about seven hours per night.

Can I use a rice cooker and a toaster on the yeti 400

Asked by: crfn
The Yeti 400 will only work on items that take 400 watts or less, you will need to check the specs of your devices in order to determine if this will work for your intended purpose. If it is more than 400 watts, the Yeti 400 has a built in charge controller and will protect itself by turning off.

What solar panels will work with Yeti 400?

Asked by: Shadowlands
I have been using solar panels on my sailboat for more than 10 years. The constraint is the panels cable connector to the goal zero YETI, din pin etc. Most cables can be modified if your are so inclined and have the skills. Unless you are going to leave the goal zero battery continually hooked up you should not have to worry about a charge controller.

What does it mean when it says the lead-acid battery has a "three-month shelf life?" does that mean it needs to be replaced every three months?

Asked by: alank
The Goal Zero Yeti 400 Solar Generator can go for three months in-between charges. Keep this plugged in to avoid having to charge every three months.

I have a small 32 gallon salt water fish aquarium and I live in SW Florida where power outage is no stranger. would the Goal Zero power my pump filter and if so, how long (approximately)?

Asked by: Makai2
This generator will power your pump filter, however, you will need to check the specifics of your device to determine how long the generator can power the filter for.

If I was trying to decide between the yeti 150 and the 400, which would be the best for car camping for a weekend or longer?

Asked by: healthyeric
Choosing the right generator depends on the devices you want to power and for how long. The Yeti 400 has a maximum output of 300 watts per hour. The Yeti 150 has a maximum output of 150 watts per hour.

How many nights will a Yeti 400 operate only a CPAP machine

Asked by: Younglundm
It would depend on the wattage of your CPAP machine. For example, this generator can power a 50 watt CPAP machine for about 8 hours. If the wattage of your CPAP machine is higher than that the run time will be lower.
