    An efficient way to store solar energy.

    Solar panels are capable of gathering plenty of energy to power the electronic devices you need whether you're car camping, working on a remote photo shoot, or staying at a yurt or remote cabin for a weekend. Making the problem of storing solar energy easier, the Yeti Lithium 400 Solar Generator improves on Goal Zero's previous designs by integrating a Li-ion battery to the system, which increases surge allowances, provides enhanced battery protection, and reduces weight and bulk of the battery pack for a more compact and efficient way to store power. Being the smaller option in the Yeti Lithium line, this 400W option is ideal for quick weekend getaways when the only electronics you need to power are phones, tablets, camera equipment, and a light or two. Each lithium battery can be easily replaced, and they can be charged through either an AC wall outlet or with Goal Zero solar panels (not included).

    • A solar power storage unit ideal for weekend camping trips
    • Li-ion batteries have long run times and higher surge allowances

    Great addition to your kit

    Familiarity:I've put it through the wringer

    This is great for car camping or a back up power source for in a camper. It is excellent for charging phones, laptops, camera equipment. Small and light weight (relatively speaking). No USB-C ports and the AC ports are quite close together (could not use two cell phone charging plugs side by side) are they only downsides I have experienced.

    camper power

    I use the 400 in my camper to charge lights, cameras, computers, ipads, phones, radios, batteries, etc. It's light and holds a charge well. Highly recommended!


    Ok, I'm loving the wood burning stove! What type is it and dies it have a fan?

    This Beast is Worth it!!!

    Familiarity:I've used it several times

    We took this on a six day road trip across the southwestern desert. We were never really around places where we could charge but we were constantly in the car. This is the fastest iPhone charger I’ve ever used. We also used it to charge all of our camera batteries and MacBook Pro and we barely put a dent in the overall power storage of this unit. One of the many features we really liked was the ability to only turn on the charger for the products we were using. Eg. if you are charging an iPhone you only need to turn on the USB Charging Ports, this saves overall power and makes the unit much more efficient. It weighs a ton but we put kept it in the floorboards of the car and never really had to move it. Without this unit we would have wasted a lot of time waiting in random places trying to charge up all of our essential electronics.

    Power is key

    Familiarity:I've put it through the wringer

    This generator can be used for multiple occasions when you are out camping. For my brother, it's used to power a flat screen tv, a dvd player, charge 2 tablets and 2 phones. It only lasts one night, but it does what my brother needs. With his family, they don't get out camping much and they like their tech! For me on the other hand, I've used it to charge 5 phones, 6 power banks, a digital camera and a couple rechargeable lamps on a 6 day river trip on the Salmon River. If you can make the weight work, it fits perfectly in a dry box and you can have power for you devices for your trip! Just make sure you charge it on the wall before you leave. We were only down to about 50% on the battery by the end of the float as well so we had no need for the solar panel. It was a real luxury to have our devices powered for the whole trip to document our time on the river. You never know when you will land another permit for the Salmon so it's nice to be able to have a lot of footage to look back at.


    Does the Lithium charge small refrigerators? Like a college dorm size?
