Goal Zero Yeti 400 Review

Goal Zero Yeti 400 Review

In this Goal Zero Yeti 400 review, we take a look at a portable generator that promises a lot. But, does it deliver?

Design & Build

Goal Zero manufacturers design portable batteries, totable solar panels and lighting hardware of 12 volts. Goal Zero Yeti 400 is another power station created by them. It is incredibly portable and it is considered to be a one-stop portable power solution. The reason why it’s so portable is because it is very compact.

It is 10.25 inches long, 8 inches wide and 8 inches high. However it is very heavy which is very surprising due to its dimensions. It weighs around thirty pounds. The reason for that is because of Lead Acid Battery which is a 396Wh ATM and Pure Sine Wave inverter which both have very tough build.

With the tough buld of Lead Acid Battery and Pure Sine Wave inverter, durability is a strong suit of this generator. The battery has an enclosed casing as well as a very tight one. It has a boxy design and the edges are similar to pillars. This also means they are quite strong and are not prone to easy damage.

The sides are made out of plastic and they also have panels. The panels are reinforced with projections which are very like the corners. This adds even more to the overall durability. There is a handle as well and it is also very thick.

How Does It Work?

Goal Zero Yeti 400 is a solar generator so many won’t know the way it works. But all in all, any solar generator you get will work the same way. The energy is collected from the sun and then stored in a battery pack. All generators with a solar panel system will have the same features. Those features include a solar panel, charge controller, power inverter as well as lead-acid lithium battery.

One thing that may make the Yeti 400 generator unique is because of its fully enclosed case. All you need to do is connect your device to USB or AC power pots which can be found on the generator. This makes the generator a lot more convenient.

Goal Zero Yeti 400 FeaturesFeatures

On the front panel of the Yeti 400, you will be able to find an LED display. This LED display will allow you to see how much battery is left, wattage amount that’s been released or stored and what’s currently connected to the generator. There are also several different ports too. We have already mentioned that there is an AC port but it also comes with an AC adapter and a 12-volt adapter. So you will be able to charge your devices either through ports or by using the solar panel.

A power management system is also included with the Yeti 400. This means that you don’t need to worry about overcharging it. When it is running, the flow of power will stop before the battery gets overcharged and, like that, protecting the battery from any damage. This generator is great for any outdoor activities such as camping. It’s also great during a power outage.One will also be able to find a heat sink and two small fans. This makes the generator last longer and we all know that heat is an enemy to electric devices.

Charging Process

According to the official specifications, this generator is able to charge a maximum of 240 watts. So, considering that information, the Yeti 400 will need to charge for about four to five hours.
According to GoalZero, the Yeti 400 can handle a maximum solar panel charging input of 240 watts. One can also power other devices while charging the generator but it slows everything down. By everything, it means that it slows down the entire charging process. So, you need to be careful with that.

However, in practice, the time needed for the Yeti 400 to charge is actually less than five hours. And that is when one uses the AC adapter. If you use two Nomad 20 solar panels when the weather is good, the Yeti 400 will charge in twenty hours. But, let’s not forget that one can also use the wall charger. With the wall charger, the charging process will last for seven hours for the maximum charge.

It’s also true that depending on the size of panel, the charging process with solar panel varies. For example, when using the 200 watts set, you will be able to charge it for less than five hours. However, first make sure there is a lot of sun first. But, if you decide to use the panel of 50 watts, it is possible for it to go for 15 hours even – or more.

The Yeti 400 uses a lead acid battery which should be taken into consideration. The more common battery is a lithium one. One advantage to using the lead acid battery is because it can withstand very cold weather. You can also replace it more easily and it’s also cheaper and has a longer lifespan.

Portable generatorPortability

With the weight of less than 30 pounds, the generator is considered to be quite portable. And, like mentioned before, the dimensions are way lower than its weight. And because of its small dimensions, you’re not going to need a lot of space for storage or transportation. The Yeti 400 has a rugged casing to make the transportation process easier.

The plastic panels are fitted very tightly so you won’t need to worry about them disenganging when you’re transporting the generator or lifting it up. Don’t expect the generator to be waterproof and there is a high chance you won’t be able to charge it outdoors with panels.
