What can the Boulder 50 charge?
The solar panel does not keep a charge while exposed to sunlight; instead, it creates power. To recharge it, connect it to a portable power source. The Boulder 50 is the finest way to refresh Goal Zero Sherpas and Yetis.

Is my Boulder Solar Panel waterproof? Yes. The Boulder 50 is waterproof and rugged terrain resistant. Just remember that the devices you are powering might not be as durable.
Can the Boulder 50 be chained? Yes. You can chain up to four Boulder 50’s.
How long will it take to charge my Goial Zero Yeti from a Boulder Solar Panel? 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.
Can I mount the Boulder Solar Panels to my roof? Sure can. The new Boulders are designed 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.
Is it possible to break my solar panel? Not easily. It was made to last, but try to avoid heavy impact that can weaken the frame and cause the glass to crack.
Can I chain a Boulder 50 with older Boulders? 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.
