FREQUENTLY ASKED QUESTIONS

• Q: What type of battery is in the Yeti 400 Lithium?
• A: The Yeti Lithium 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.

• Q: How do I know if my device will work the the Goal Zero Yeti 400 Lithium
• A: 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 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. 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 Yeti, you’ll want to check the restrictions on each of the output ports.

• Q: Can I replace the battery in my Goal Zero Yeti?
• A: Yes, the battery inside the Goal Zero is designed to be easy to replace.
  
• Q: How do I know if my Goal Zero Yeti is charged?
• A: 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.
  
• Q: Why is the light on the AC button blinking?
• A: 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.
  
• Q: Charging from Solar?
• A: When solar recharging your Goal Zero Yeti Lithium, take note of the voltages of the solar panels and do not exceed 30V. Individual solar panels, or solar panels chained in a series in excess of 30V cannot be used with the Goal Zero Lithium and can cause serious damage to the unit.

THE GOAL ZERO YETI 400 LITHIUM POWERS YOUR DEVICE IN 3 WAYS:

USB
4 high-speed USB ports (2.4A). Great for your phones, tablets, and wearables.

12V
The 12V best charges all your 12V powered devices. (10A, 120W max)

AC Inverter
Plug in your device just as you would the wall. There are two AC Outlets (pure-sine wave, 300W, 1200W surge)

WHAT TO POWER FROM THE GOAL ZERO YETI 400 LITHIUM:

Smartphones, Lights, Camera Equipment, Tablets,12V Appliances, Laptops, CPAP, Display Monitors, etc.

HOW LONG WILL IT TAKE TO CHARGE YOUR DEVICE FROM GOAL ZERO POWER PACKS?

It takes the same amount of time to charge your device from a Goal Zero power pack as it does from the wall.

BEST-USE STRATEGY:

When charging gear with the Yeti 400 Lithium, take note of the LCD Battery Display. If you plug in devices that have a high power requirement (a large refrigerator), the charge level of the Yeti can drop very quickly and you may not get exactly 400Wh of energy. Also, especially when using the AC power output, the Goal Zero Yeti will be converting the energy from the DC power of the battery to the AC power needed by your device. Although your Goal Zero Yeti has a highly efficient inverter, there is still some energy lost in the conversion and you will not get the full rated capacity of the battery.

COLD WEATHER USAGE:

Cold temperatures (below freezing) can impact the Yeti’s battery capacity. If you’ll be living off-grid in sub-zero conditions, we recommend keeping your Yeti 400 Lithium in an insulated cooler, connected to a power source (solar panels), and charging your gear. The natural heat generated by the Yeti 400 Lithium contained in an insulated cooler will keep battery capacity at its highest.

STORAGE AND DOWNTIME MAINTENANCE

Having your Yeti 400 Lithium connected to a power source, like a solar panel or wall outlet, between adventures or while in storage keeps its battery healthy and topped off. This prolongs battery life and will ensure your Yeti 400 Lithium is charged and ready to go all day, every day.

If you can’t keep the Yeti 400 Lithium plugged into a power source during storage, fully-charge your Yeti 400 Lithium every 10-12 months and store in a cool, dry place. Failure to maintain the Yeti 400 Lithium by following these steps can result in battery damage which will void the product warranty.

WHAT CAN THE BOULDER 50 SOLAR PANEL CHARGE?

The solar panel does not hold a charge it produces power when it is exposed to sunlight. You can store the power it produces in a portable recharger. The Boulder 50 can be used to power any Goal Zero power station. If you’re looking to recharge things like headlamps, phones, and other USB devices directly from the sun, check out our foldable Nomad Solar Panels.

WHAT GOAL ZERO PRODUCTS WORK BEST WITH THE BOULDER 50?

The Boulder 50 can be used to power any Goal Zero recharger. For the amount of Watts it gives, it will be most effective with the Yeti 150, Yeti 400, Yeti 1250, Yeti 1400, Sherpa 50 or Sherpa 100.

DOES THE BOULDER 50 GIVE A FULL 50 WATTS?

It delivers up to 50 Watts of power, but the angle of the panels and the cloud coverage can impact its performance. Avoid the shade. It will not work indoors.

FREQUENTLY ASKED QUESTIONS

• Q: Is the Boulder 50 waterproof?
• A: Yes. The Boulder 50 is waterproof and rugged terrain resistant. Just remember that the devices you are powering might not be as durable.
• Q: Can the Boulder 50 be chained?
• A: Yes. You can chain up to four Boulder 50’s.
• Q: How long will it take to charge my Goal Zero Yeti from a Boulder Solar Panel?
• A: That depends on a few factors – how big the Yeti, how cloudy it is, how hot it is, just to name a few. All the Yetis allow for something called “pass-through power”, this means you can be trickle charging your Yeti and using it to power your gear, all at the same time.
• Q: Can I mount the Boulder Solar Panels to my roof?
• A: Sure can. We designed the new Boulders to work with traditional Z Brackets so they’re easier to install. Pairing a Boulder Solar Panel and Goal Zero Yeti Portable Power Station for a camper or van? Talk about a match made in heaven.

• Q: Will the Boulder 50 break?
• A: Not easily. It was made to last, but try to avoid heavy impact that can weaken the frame and cause the glass to crack.
• Q: Can I chain a Boulder 50 with older Boulders?
• A: Two part answer. Yes, you can chain the Boulder 50 with older Boulders that have blue-ringed 8mm connector (Boulder 15 Boulder 30). If you are the proud owner of a Boulder 90 Solar Panel with its MC4 Connector, you’ll want to ensure that you have an MC4 to 8mm adapter, as well as an Anderson Power Pole Combiner Cable. In fact, any instance when you’re chaining more than 150 watts of solar panels together (ex. Boulder 100 with two or more Boulder 30s), we recommend using the Anderson Power Pole Combiner Cable.
