The Goal Zero Yeti 200X uses a customer designed lithium ion battery. The battery in your power station is secured in a protective enclosure with a battery management and protection system that helps control its terminals. Do not let the battery wet. If moisture gets into the battery cells, it can bypass the battery’s protective systems.

Start by determining the amount of power your device requires. You can do this by searching online or consulting your user guide. Next, check the capacity for the individual output ports. For example, the Goal Zero Yeti's AC port is powered by an inverter that allows for 2000W of power. If your device pulls more than 2000W of power for an extended period of time, the Goal Zero's inverter will shut off.

You’ll also want to compare your device’s surge rating to that of the Yeti’s port. The Yeti power station has an advanced surge management system that maximizes its compatibility with most devices, but there are some that surge at a higher rate and for a longer time than the Goal Zero Yeti can manage. When using one of these devices, the charging port will turn itself off.

Finally, in some situations, such as running a 12V device directly off the 12V port, there will be minimal conversion and very little additional loss. When using the USB ports to charge a phone, you add a layer of conversion (a 12V battery in the Yeti is being converted to a 5V USB output), which introduces about 10% of loss. When using the converter, there are two layers of conversion (12V to high voltage, DC to AC). The least efficient way of using the Goal Zero Yeti's battery is to use an AC-DC adapter off of the AC ports (such as when you use a phone wall charger to charge your phone) because this adds yet another layer of conversion in the wall adapter. When deciding what to power from your Goal Zero power station, be sure to research your devices' watt consumption first.

No. FAA regulations prohibit taking any battery exceeding 100Wh on a plane. Visit FAA Pack Safe for more information.
