Temporarily connect a Goal Zero Yeti 1250 to a 100 amp hour (or similar) 12V lead acid battery (175 amp max) to share power for longer run times.
OUR POWER PACKS CHARGE A WIDE RANGE OF DEVICES
To better help you understand your power needs we've divided our products into 3 categories. To see the individual products we offer in each of these categories click below.
Our Compact class of products are perfect for charging devices with low-power needs such as cell phones, mp3 players, headlamps, and more.
Our Mid-Size class of products are perfect for charging devices with low or medium power needs such as tablets, laptops, DSLR cameras and more.
Our Heavy-Duty class of products are perfect for charging devices with low, medium, or high power devices such as TVs, small refrigerators, CPAP machines and more.
You can power devices directly from a solar panel, although for the most reliable experience we recommend storing power and charging your device from one of our Power Packs.
CAN MY DEVICE RUN DIRECTLY FROM A SOLAR PANEL?
MOST USB AND 12V DEVICES CAN CHARGE DIRECTLY FROM SOLAR PANELS, IF THE WEATHER CONDITIONS ARE GOOD ENOUGH.
Small USB devices like cameras of MP3 players require 1-2.5W of constant power to charge. Our panels can easily provide this amount of power even in sub-ideal conditions. Smartphones and tablets have a higher power requirement, ususally around 5W of constant power. A 7W rated solar panel will only produce 5W in perfect sun conditions, and because smartphone are quite picky about their power requirements, they can "give up" charging if there is ever an interruption in constant power - like when a cloud passes by overhead.
For the best experience, we recommend using a Goal Zero battery pack as a buffer, instead of charging directly from the sun, for the following reasons:
Goal Zero's mission is to empower people because they believe in human potential. The potential to go farther and do more than you ever thought possible; the potential to provide a sustainable future for you and your family; the potential to make a difference in the lives of people everywhere.
Frequenty Asked Questions
WHAT IS THE GOAL ZERO WARRANTY?
The warranty period for GOAL ZERO battery cells (whether purchased on a stand-alone basis or as part of another product) is 180 days. The warranty period for all other GOAL ZERO products and components is one (1) year. In each case, the warranty period is measured starting on the date of purchase by the original consumer purchaser. The sales receipt from the first consumer purchase, or other reasonable documentary proof, is required in order to establish the start date of the warranty period. If you completed the online GOAL ZERO Product Registration Form within 30 days after purchasing your product, that registration can also establish the start date of the warranty period (but warranty coverage is not conditioned upon such registration).
WHAT DOES GOAL ZERO MEAN?
That's a hard one to answer - so much in two words! When there were five of us sitting around a table, dreaming about what we wanted our company culture and mission to be, we kept coming back to our roots of empowering people and taking a risk in a new industry. What came out of these discussions was our mission statements: ZERO apathy - we take risks, we're passionate about what we do and we are brave. ZERO boundaries - we don't take no for an answer. We find solutions and create products that people didn't even know that they needed. ZERO regrets - we work hard and we play hard. GOAL ZERO isn't just a company, it's a business created by people who live life to its fullest, with a shared vision inspired by the passion for adventure, respect for the planet and a humanitarian heart. We're a company that equips families and individuals seeking to improve the outdoor experience with the most innovative portable power products on the market. Field-proven in some of the most remote places on earth, we are working to continually deliver smart, innovative power solutions that will change the way you adventure.
DO THE NOMAD 7/ GUIDE 10 WORK WITH IPHONES AND SMART PHONES AND WHAT ARE TROUBLESHOOTING TIPS?
Yes, the Guide 10 and Nomad 7 work with iPhones, although we've found that new generations of iPhone 4's can be fairly unruly. Some troubleshooting tips are:
WHY ISN'T MY ESCAPE 150 (SCOUT 150 OR GOBE IN PREVIOUS LIVES) LCD SCREEN SCROLLING WHEN I PLUG IT INTO A POWER SOURCE?
If the power pack is already charged fully, the battery icon on the LCD screen will not scroll when it is plugged into a power source. The battery icon will show that it is fully charged. However, if the battery is plugged into a power source and it does not hold the charge and the battery icon on the LCD screen does not begin to scroll, there's a chance that your battery has died for lack of use. We recommend using and powering your Escape 150 power pack every 3-4 months so that it doesn't die.
WHY ISN'T THE BATTERY INDICATOR LIGHT ON MY GUIDE 10 GOING SOLID GREEN?
The blinking green and solid green indicators are actually very close in power capacity. It takes a longer time to top off a battery to the full capacity, kind of similar to filling the last few seats in a stadium. A stadium fills quickly until it reaches about 80% capacity. Then people have to start tiptoeing around each other, slowing finding two seats here, three seats there, and it takes a longer to fill the stadium to 100% capacity. We call this the stadium effect when it comes to charging the power packs.
HOW DURABLE ARE GOAL ZERO PRODUCTS?
I'll answer that question with a question: how durable is Chuck Norris? No, but seriously, our products are designed to be your hero. We've designed the panels and power packs to be rugged and weather resistant. Our products are sent around the world to be tested in a variety of temperatures, elevation and humidity levels. We really wanted to say that the solar panel is water-proof, since we've seen the panels work while they are under water. But since we can't guarantee that outcome 100% off the time, we say they are weather-resistant. The panels do fine in the elements, from rainy season in Congo to snowstorms in Everest. The panels can be scratched up, run over, left in the rain, and they'll still charge up your gear. The power packs are also water-resistant, but should not be submerged in water, in order to prevent rust in the junction box.
CAN THE NOMAD 7'S CHARGE UP ANYTHING OTHER THAN THE GUIDE 10 POWER PACK? ARE THE NOMAD 7'S CHAINABLE?
You can always charge your small electronics that are powered by USB or 12-volt (car adapter) directly into the Nomad 7. It's designed to charge up the Guide 10 power pack quickly, however, if you have a larger power pack like the Sherpa 50, the Nomad 7 can charge it with an additional cable, although we don't recommend it since there are more efficient panels that can do the job faster. In order to do this, you'll need the 4.7mm extension cable. Simply plug the 4.7mm extension cable into the 12V port on the Nomad 7, then connect the cable into the input port of the power pack. (Secret: The Nomad 7 can even charge non-Goal Zero batteries using the 4.7mm-to-alligator-clips adapter cord.)
As far as being chainable, the answer is yes and no. It is possible to chain the Nomad 7 to other GOAL ZERO panels with the 4.7mm extension cord. However, the Nomad 7 doesn't have an input port, like our other panels, so it can only be the 'caboose' in a chain of other GOAL ZERO panels.
WHAT IS THE LIFE SPAN OF THE BATTERIES AND PANELS?
The Sherpa batteries have a life cycle of 2,000-3,000 cycles. The Escape 150 and the Extreme 350 both have 500-1000 cycles. The Nomad solar panels have a 5-8 year life span and the Boulders and Briefcase have a 20-year life span.
WHAT TYPES OF BATTERIES DOES GOAL ZERO MAKE?
The Guide 10 batteries are Nickel Metal Hydride. The Sherpa batteries are Lithium Iron Phosphate. The Escape and Extreme are Sealed Lead Acid batteries.
