I was attracted to the lightish weight and the ability to charge from solar panels, and it seemed like a great option for keeping cell phones, cameras, and laptops charged while very much off the grid. The Goal Zero Yeti 400 worked for about a month with maybe 5-6 laptop charges over that time and some cameras and cell phones. Afterwards, it would no longer charge from the solar panels.

I feel like a fool for having bought this, and I made the bigger mistake to have bought the large unit with 2 suitcase panels. Yes, I got suckered into the advertising.

It is a scam.;;Reviewed in the United States on July 23, 2018;;1.0 out of 5 stars;;Please I beg you, DO NOT BUY THIS Very expensive useless paper weight.;;Sandra;;;Battery, inverter, various outlets, amp meter, volt meter, regulating various input sources. Trying to piece tougher a compatible solar system that can be charged from multiple sources and power items with various 12-volt attachments can be a wiring mess and complex to figure out, especially for relatively minor electric needs. The Yeti 400 has figured this all out so you don't have to and offers it in one convenient package. Simply plug it into a standard household electric outlet, your car's cigarette lighter or a solar cell to charge with no need to worry about what regulator/controller you need to charge it properly without overcharging. Various outputs are also ready to use, making it very adaptable. While very convenient, the included 33 AH battery offers fairy limited storage capacity for a 12-volt system. This can be doubled or tripled however by chaining additional compatible batteries, to create a 100AH system. I used this primarily to power a small dometic fridge on road trips when base camped for a couple days when 110 or car power was unavailable. (one additonal battery chained) Most complaints, I've read are not so much problems with the unit itself, but people not realizing how limiting a 33 AH capacity battery really is, or not understanding how solar cells really charge. Here's a few key points that have been mentioned in other reviews, that I think are worth mentioning again: 1. 33 AH isn't a lot storage. You can't expect to power notable electric needs with this. Calculate your actual needs before purchasing. No 33 AH battery system will fulfill a 50 AH need without recharging. 2. in fact, a 33 AH capacity doesn't even mean you can power something requiring 3.3 amps for 10 hours. Many things won't run on a near dead battery, draining, a battery to zero isn't good and when trickle charging especially, it's hard to get a full charge. (One could write an entire book chapter on the nuances of this alone) 3. If charging via solar, realize a 100 watt solar cell will not increase your battery storage by 100 watt hours for every hour light is shining on it. 100 watts is the max output that solar cell will produce under ideal conditions. Many factors can decrease the efficiency of your solar charging. Read up on it. Other reviews and other sources go into great detail about how to calculate electric needs, what you get from a given capacity, and how to calculate what you will get from solar charging. My point is simply that if you have unrealistic expectations, you will likely be disappointed.(with any 12-volt system) Spend the time to accurately figure out your needs, whether this meets your needs as is, whether you need to chain additional batteries, add more solar, etc. Having wired a couple sailboats myself, I have to say the convenience of a single self contained, portable system has it's benefits, but total storage is not one of them. In terms of a well thought out, convenient system, I might give the Yeti 5 stars. I give it 4 primarily due to the relatively high cost for the relatively low storage capacity it has. Some better accessory cords would also be nice. Chaining with allegator clips for example. I certainly have no regrets about this purchase.;;Reviewed in the United States on November 21, 2016;;4.0 out of 5 stars;;Convenient and fairly complete 12-volt system. Pricey, low storage.

That was the low battery warning sound. Who knows how long it's been that way. It didn't charge at all overnight. The battery was completely shot.

Not dependable
We purchased our Yeti a year and a half ago. It has never seemed to work correctly and has just gone downhill. We have discovered it is not fully charging. We plug it in to the wall and it will say it is fully charged. Once we plug something in to it, it immediately drops to 60%. It seems to only be getting a surface charge. We bought this to run a CPAP while camping and we’re kucky to make it through one night. It is a great concept, but it is unreliable and way too much money for such unreliability. I’ve found on comment boards others having similar problems. Quite disappointing.

Note when ordering from Amazon: The manufacturer makes it very clear these batteries should be charged up at a minimum of every three months. There's a very real chance you will order a battery that's been sitting on a shelf uncharged for longer than that. When my battery arrived, it was beeping inside the box. That was the low battery warning sound. Who knows how long it's been that way. It didn't charge at all overnight. The battery was completely shot. Fortunately I have a battery tender plus and after about 24 hours my battery was brought back to life, so it is possible to save it if yours arrives dead and unable to charge from the wall. As far as the battery itself, it's great! There are plenty of glowing reviews here and on Youtube. I paired mine with a WindyNation 100w flexible solar panel. Very light and much cheaper than what Goal Zero sells. Taped it on top of my canopy tent. You just need to buy the Goal Zero MC4 adapter to get it working. Would recommend an extension cable too if your panel will be far from your Yeti.
