Frequently Asked Questions

What type of battery is in my Goal Zero Yeti?
Your Goal Zero Yeti uses custom designed Lithium Ion. Here are some basic facts about
Lithium Ion batteries:
1. Lithium Ion batteries can store and release a lot of energy in a short period of time.
The batteries in your Goal Zero Yeti are in a protective enclosure with a sophisticated
battery management and protection system controlling its terminals to the outside world.
2. It is critical that your battery does not get wet as moisture and water can get into the
battery cells behind the protection circuitry and bypass that protection.
Can I replace the battery in my Goal Zero Yeti?
Yes, the battery inside the Goal Zero Yeti is designed to be easy to replace. Replaceable
batteries will be available from GoalZero.com. Call us at 888-794-6250 for assistance.
How do I know if my Goal Zero Yeti is charged?
To check the charge level of your Goal Zero Yeti, refer to the LCD 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.
Why is the light on the AC button blinking?
A blinking light on the AC button indicates that at the current load, the AC inverter will be
shutting off soon; you should also see RESERVE MODE blinking on the display. Recharge
your Goal Zero Yeti as soon as possible to continue powering your device. Once the AC
inverter has shut off, the Yeti will attempt to reset itself three times. After three attempts,
the AC inverter will remain off until you physically reset it by pushing the AC button or by
recharging the battery a small amount.
Why is the light on the 12V button blinking?
A blinking light on the 12V button indicates the 12V car port has been shut off to protect
whatever you have plugged in; you should also see RESERVE MODE blinking on the display.
Recharge your Goal Zero Yeti as soon as possible to continue powering your device.

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 300W of power.
This means if your device is pulling more than 300W 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.
Finally, once you know your device is compatible, you'll want to determine how long you'll be
able to power your gear from the Goal Zero Yeti. Here's a quick and dirty lesson in power.
All GOAL ZERO power packs and solar generators have a number in their name, ex.
Guide10 Plus Power Pack, Goal Zero Yeti 400. These numbers refer to the Watt Hours
(Wh), or the amount of energy that can be stored in each recharger, and how you'll know if
your gear is compatible with each recharger. For example, a 200Wh recharger should run
a 100W light for 2 hours (200/100=2). If your gear falls within the 400Wh capacity of
the Goal Zero Yeti, you'll want to check the restrictions on each of the output ports.
Another factor in the math is how much power is being converted going from the Goal
Zero Yeti battery to the device you are powering/charging. In some situations, like when
running a 12V device, such as the LAL 350, directly off the 12V port, there will be no
conversion and so no 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.
