I have been using both the Sherpa 100 and Yeti 150 for a couple of years now. When using solar to charge them I was using Nomad 20s, which have done a good job. This year I am "experimenting", if you will, with keeping my iPhones and iPads charged only with solar power. I want to see how viable solar is for this purpose. The Nomad 20s were doing a good job, but given our at time sporadic sun here in Michigan I wanted to try a little more horsepower. The Boulder 50 is living up to Goal Zero's claims / my expectations. As with all Goal Zero products I love the "plug and play" aspect of the design. When this puppy arrived I unpacked from the well protected boxing and placed in the yard to put it to work. I've never had the Sherpa 100 charge so fast on solar. I was certainly happy with the purchase. I now rotate the two power supplies, to give them "equal time" and the Boulder 50 just keeps them happy. Even when down for a couple of days, due to rain, the chargers are brought back to life in short order. I am very happy with the purchase and highly recommend the solar panel.
I would recommend this to a friend!

These are amazing. I was finally able to draw my Yeti 300 down to about 60% power. With mostly sunshine in northern Michigan I was able to Chatge my Yeti back to 100in about 4 hours with two chained. Was able to achieve a max of 72 watts even without a totally clear sky
I recently purchased a Yeti 150, Boulder 50, 2 sets of brackets, and a 15' 8mm extension cord, all to use in my truck camper. I got my order within a short time and in good condition. Love the Yeti 150, especially since our two day power outage this week. I had power to keep phones, tablets, and lights running with no problem. Looking forward to being off grid traveling on short trips soon. Very happy with the product and the ease of installing the panels on my truck camper.

Not getting the juice I expected

I bought this to power a yeti 400. I have been in touch with goal zero in hopes to remedy this situation. Full sun I am getting 17 W. This can't be right. If there is a small shadow at all, charging goes to nothing. The reason I write this is for you to check your system with lots of time to get it remedied. I am not pleased with the performance at this point, it doesn't meet what I expected. I wasted a week, should have sent it back first day.
I could not be happier. The Boulder 50 may not be "portable", but it is the perfect pairing in my mind for the Yeti 150 as it chargers the battery very quickly. For my needs, I was just looking the Yeti to power a laptop and cell phone while at a coffee shop or while climbing.
Gave a "super starter Goal Zero" package (Yeti 150, Boulder 50, Light-A-Life 350 & car charger) to friends who go off surfing and camping in their van 2 or 3 times a month. They were super stoked.
Purchased the boulder 50 for my yeti 400, used it yesterday and almost charged the yeti to full from 20%. great purchase. Wish theres a case to put the boulder in to protect it better and transport better.
