Took one point off for the design. Having the panels be on the outside when you fold them up makes me nervous when putting away in their bags, or trying to set them down before opening. The panels themselves are really good. I was able to get 75..80W from each of them, and they are heavy enough that so far winds have not moved them at all. So far I have 4 of these linked to my Yeti, and they are working quite well.

The construction of this folding briefcase solar panel is of the highest quality!Pairing with a Yeti generator for charging,it keeps My ARB refrigerator operating with no problems! I recommend this product, I'm sure it will provide many years of Service!

This product is quality and folds to more be compact for transport. Goal Zero is a great company to do business with. The product is as described and the shipment was made the day after the order was placed.. I will gladly use Goal Zero again for my solar generator needs!

This unit works great to recharge my backup power supply.

This is the first time we've purchased such a product, and so far so good. We were surprised that when the panels fold to go into the carrying bag, they fold with the solar panels facing outward. Seems like if the panels were facing inward, they would be better protected for transport. Thank you.

I just received my Boulder 100 Briefcase Solar, and have not yet tried it. However, I am forced to question why the glass part of the panels is on the outside when folded. If the panels faced each other when folded surely that would offer more protection against damage for them. i like the idea that the panels do not require any installation to charge my Goal Zero Yeti 400, so it will not be necessary to drill holes into the roof of my RV. Earth Tech provided free shipping and handling as well as an additional 10% off the $****** price shown, so that was a good deal compared to other manufacturers.
