THE GOAL ZERO YETI 1250 POWERS YOUR DEVICE IN 3 WAYS:
Three 2.1A USB Outlets. The USB port best charges all your large sized or multiple USB powered devices.
The 12V best charges all your 12V powered devices.
Plug in your device just as you would the wall. There are three AC Outlets (pure-sine wave)
WHAT TO POWER FROM THE GOAL ZERO YETI 1250:
Smartphones, MP3 Players, Digital Cameras, E-readers, Tablets, Lights, 12V Appliances, Laptops, CPAP, Display Monitors, Appliances, Fridges 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.
When charging gear with the Yeti 1250, 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 1250Wh of power. On the flipside, if you're recharging devices that draw power more slowly (a small TV), you will get closer to 1250Wh. If you're experiencing shorter run times, you make want to check the device's power requirements.
COLD WEATHER USAGE:
Cold temperatures (below freezing) can impact the Yeti's battery capactiy. If you'll be living off-grid in sub-zero conditions, we recommend keeping your Yeti 1250 in an insulated cooler, and connected to a power source (solar panels). The natural heat generated by the Yeti 1250 contained in an insulated cooler will keep battery capacity at its highest.
STORAGE AND DOWNTIME MAINTENANCE
Having your Yeti 1250 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 1250 is charged and ready to go all day, every day.
If you can't keep the Yeti 1240 plugged into a power source during storage, fully charge your Yeti 1250 every 3 months and store in a cool, dry place. Failure to maintain the Yeti 1250 by following these steps can result in battery damage which will void the product warranty.
CHAINING YOUR YETI 1250
Looking for more power from your Yeti 1250? You can extend the run time of your Yeti 1250 by connecting it to additional 12V, 100Ah batteries. The connector on the back of the Yeti 1250 is an Anderson Power SB175. Connect only 100Ah, 12V lead-acid batteries (or similar, 175Ah Max) batteries to the Yeti 1250.
When additional batteries are chained to the Yeti 1250, you will experience increased charge times - this is a result of having to charge up the chained batteries in additional to the Yeti 1250.
