I have purchased, used and tested every lightweight solar charging device on the market that I could find. The Goal0 nomad 7 and Guide 10 set is the only one that works sufficiently that I can be completely off the grid with my backpacking devices and have no need for extra batteries. See below for solar panels tested. I have been testing portable solar panels for several years now, and the Goal 0 products are the best. The Nomad 7 is the only solar panel that has the capability to charge an adequate battery pack, my headlamp AAA's, AND my smartphone/GPS all in the same day in full sunlight. It is the only panel that has reserve capacity to charge my devices in less than full sun (shady/cloudy). No other panel has the output of the Nomad 7. Its closest competitor is the Brunton panel. The Brunton weighs 20% more and is rated to output 30% less than the Nomad 7 (Brunton = 5 watts, Nomad 7 = 7 watts). In my testing the lower output was verified. The off-axis performance of the Nomad 7 is superior. It maintains full output to a greater angle of sun than any other panel I have tested. The Nomad 7 is the only panel, in my knowledge, that uses the more efficient mono-crystalline panels. It does seem to give it an edge in real-world usage. As far as flexibility, that characteristic has nothing to do with panel efficiency. Another of the well-thought out features of the Nomad 7 is the connection options. The Xpal SP-2000 and the Solio both rely on many different tips to connect to different devices. The Nomad 7 has three great options built in: 6.5 volt fast charge for the Guide 10 charger, 5 V USB connector, and a port that the included 12V female car lighter adapter plugs into. Every portable device has the option of an inexpensive car power adapter, and the Nomad 7 nicely offers that ability. The Guide 10 charger works to its rated specifications, unlike most of the other solar devices I have used. It charges AA and AAA batteries. It charges them faster with the Nomad 7 than any other solar panel/charger combination that I have tested. The Goal 0 batteries that ship with the Guide 10 are the best of their type I have tested. They are low-discharge, like the Eneloops, but much better. The Eneloops are rated at 2000 mAh, but charge only to about 1900 mAh capacity. The Goal 0 are rated at 2000 mAh, but charge to 2200 mAh. The guide 10 has some very well thought out features, including the LED flashlight, the function switch and the built-in hanging loop. These touches all demonstrate that the designers are users, and thought well about how these devices would be used. All is not perfect, though. The Guide 10 does have an overheating problem, but only in very strong sunlight and under certain conditions. This is a known issue that is being fixed as I write this. This brings me to one of my most important experiences; customer service. Goal 0 has the best customer service by far than any other of the solar panel manufacturers I have tested in this group. Immediate phone contact, responsiveness to questions and warranty service are far and away some of the best I have experienced. Following is a list of the solar panels I have tested, and short comparison comments on each.1. Powerfilm USB + AA: This one has a great form factor, is flexible and very durable, and is the lightest weight and most compact of all the solar chargers. Its fatal flaw is that it simply does not put out enough power to be practical in extended backpacking. It does not fully charge the AA batteries when it indicates a full charge, and is not nearly as flexible as the Nomad 7 for connection. The unit was replaced on warranty, but the replacement performed exactly the same. I tested a total of four of these, and all performed the same. Customer service was good, after spending weeks trying to get their attention, and this happened several times.2. Solio Classic: This one has a nice form factor, but the unit simply does not charge its internal battery nor a connected device at all adequately. Just in case, I had it replaced on warranty and the replacement performed exactly the same.3. Xpal Power SP-2000: Same as the Solio. Internal battery rated at 2000 mAh, only charges to about 1100-1300. Not enough power overall to be practical. Very good customer service.4. Brunton Explorer: A good panel, but not enough overall power. Weighs 20% more than the Nomad 7, output is 30% less.

This charger ships without batteries. That is not at all clear from the product description.It does ship with what looks like the AAA insert. Again that is not mentioned in the product description.Additional info:I had purchased a AAA adapter and batteries separately and so I have been able to use this product. With the 4 x AAA the pack works great. I was able to fully drain the batteries this weekend and after just 2 hours on the Nomad 7W panel they were full again. I used the pack today at work to recharge my Sansa Clip and set of Tweakers. After charging both devices the pack just started slow green blinking which means it just hit the 2/3-1/3 charge remaining.Other than the product description I have had a wonderful experience. I am going to adjust my rating from 3 to 4 stars.

It melted.I had it one week. I was using it with the correct solar panel and it was tucked inside of the pouch that was designed for it. So, I guess that the plastic that it is made from is not designed to withstand the heat of sunlight; even though it has to be in sunlight to charge. Go figure.
