Four Boulder 15 (Version 2) items arrived with two of the four panel Junction Boxes unsecured / glue separated. Packaged considerably better than in the past. Junction bo
"The Boulder 15 can be used to power any Goal Zero recharger." True, if you have the proper adapter. Out of the box the Boulder 15 has only a 4.7mm male connector. I have used it to charge my Sherpa 50 and Yeti 150, but it requires the 4.7mm to 8mm adapter. You can also charge cel phones directly if you have the 4.7mm to 12v female adapter that many cel phones can plug into. It's no big deal to get these from Goal Zero, but it would have been better if they came with the adapters needed to use them. Having said that, they do work great, either individually or chained together.
I use the pack with 3 solar panels and run an ac powered boom box when I am camping in the mountains where no power is available. It also runs lighting and other things that are a luxury when your up in the sticks(woods) for weeks at a time. It also comes in handy around the house when I need power where none is available
i first bought two of these on a deal i have them daisy chained together for a total of 30watts i dont have a watt meter for these yet but i am possitive basied on research they will never give 100% output closer to 60% on a great sunny day i have another 45watt solar array (3x15 watt pannels) from harbor freight i must say these seem to charge my batteries up faster and another plus the boluder 15 pannels are 1/4 the size of the harbor freight ones i ended up buying the kit with 8 pannels and tripod for 400 (this kit was by far cheaper than trying to buy 4 boulder 30's and a tripod) dont have a battery for all of them yet but all of my pannels work i checked overall very pleased maybe ill get more down the road
I would recommend this to a friend!

I have used the Boulder to charge my escape 150. It has worked exactly as described. I am very happy with the product.
