How long will the Yeti run my device?
Please refer to our runtime chart at https://www.goalzero.com/product-features/portable-power-stations/#chargetime. Here’s a quick and dirty lesson in power:
All Goal Zero power products have a number in their name, ex. Venture 30, Flip 36, Goal Zero Yeti 500X. These numbers refer to the Watt Hours (Wh), or the amount of energy that can be stored in each battery, and can help estimate how long your gear will run from each power bank or power station. For example, a 500Wh battery should run a 100W light for 5 hours (500/100=5). If your gear falls within the 500Wh capacity of the Yeti, you’ll want to check the restrictions on each of the output ports. When you’re deciding on what to power from your new Goal Zero power bank or power station, it’s helpful to look into your device’s wattage consumption.
How do I know if my device will work with the Goal Zero Yeti ?
First, you’ll need to determine the amount of power your device requires. This may require some research on your end, a good internet search or examining the user guide for your device should suffice.
Second, you will need to 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. This means if your device is pulling more than 2000W for an extended period of time, the Goal Zero Yeti’s inverter will shut off. Another number to watch for is the surge rating of your device as compared to that of the port. The Goal Zero Yeti inverter has an advanced surge management system that will maximize its compatibility with various devices, but there will still be items that will surge at a higher rate, and for a longer time, than the Goal Zero Yeti can manage, in which case the port will turn itself off.
Lastly, in some situations, like when running a 12V device, such as the Light-a-Life 350, directly off the 12V port, there will be minimal conversion and thus very little additional losses. In using the USB ports to charge a phone, you add a layer of conversion (12V battery in the Goal Zero Yeti is being converted to a 5V USB output), which introduces around 10% of losses. When using the inverter, there are two layers of conversion (12V to high voltage, DC to AC). The least efficient way of using the battery in the Goal Zero Yeti is to use an AC-DC adapter off the AC ports, as is the case if you use a phone wall charger to charge your phone, as it adds yet another layer of conversion in the wall adapter. So when you’re deciding on what to power from your new Goal Zero power station, do some research into your device’s watt consumption.

How do I know if my Goal Zero Yeti is charged?
To check the charge level of your Goal Zero Yeti, refer to the Battery Display. When lit up, you’ll see a battery outline with 5 segments, indicating the current charge level. It is OK to use your Goal Zero Yeti even when it’s not fully charged.
