Goal Zero Yeti 400 is an ideal choice if you are willing to power up your small electronic devices quickly and efficiently. It makes no disturbing noise while working. With this power bank, you can charge almost all of your devices, for example: laptops, cameras, smartphones, iPads, tablets and so on… The significant fact is that you will need almost the same time to charge your devices from a wall socket and from Goal Zero Yeti 400. There are three ways to charge Yeti 400: You can charge it with a compatible solar panel (Goal Zero Nomad 20, etc.), or from an ordinary wall socket, also it can be charged by a car with a 12V adapter. This product is equipped with wave inverter, which protects it from overcharging and gives you an opportunity to charge every device safely without any fault. The weight is 29 lbs (13.2kg). It is also chainable with other products. Perfect portable power bank for camping and other outdoor adventures. After the first use of Goal Zero Yeti 400 you will simply fall in love with it, and that is a guarantee. It is equipped with a LED display on the front panel that indicates the battery level, wattage of power that flows in and out, and what is currently drawing power. The front panel is the place where you will find all the connection ports too. With the included AC adapter, you have an input to charge the Yeti 400 using solar panels, a 12-volt adapter, the same as you have in your car, or also you can charge it via Goal Zero solar panels such as the Goal Zero Nomad 20 that is reviewed on that website. I will be more concrete and mention all the outputs: a collection of 12-volt ports, two ports for connecting a variety of laptops, a pair of USB ports, and two grounded AC ports, so basically it has everything you will ever need in order to provide your electronic devices with battery juice quickly and efficiently. The Yeti 400 features a Power Management System so it eliminates the risk of overcharging, meaning that it will stop the flow when you are using it right before the battery’s reserves are depleted in order to protect the battery from damaging. It is capable of keeping your smartphones, tablets and other electronic devices charged up for several days, so you will always be able to use the lines of communication when needed, as long as they are provided in that area. No matter you are camping, waiting out a storm, or so on, this generator can brighten up your life. Additionally, you can chain up to eight Goal Zero’s LED lights to it, giving you an ability to illuminate a campsite or an entire house for hours. I admit that some people might find it kind of expensive, but you have to trust me that if you prefer having a comfort without having to worry about blackouts in the face of a natural disaster, or some unpredictable event, and you want to have a reliable electricity that will be well worth the price, I suggest you purchasing the Goal Zero Yeti 400 Portable Power Station.
