Tourists who care about the weight and volume of their equipment, to solve the problems of ensuring the operability of electronics in long trips, should pay attention to the use of solar energy. Using solar panels, such as the Goal Zero Nomad 7 presented here.
Goal Zero Nomad 7 solar panel for recharging AA batteries and electronic mobile device batteries from the sun when traveling.
Probably everyone at least once faced with a situation when on a hike or travel there was an acute question of charging or providing batteries for any small-sized electronic devices of a video camera, camera, phone, GPS receiver, e-book, flashlight, radio, etc. To solve this problem, taking with you a large number of batteries or rechargeable batteries is not always possible. Indeed, for example, only one GPS-receiver with two AA batteries, with an average operating time of 14-16 hours, will force you to take them in a five-day trip in the amount of ten pieces. But there are also other devices.
The Goal Zero Nomad 7 solar panel is made in the form of two monocrystalline solar panels sewn into a case, which folds up for easy carrying. An inverter with three port sockets is mounted on the case: standard USB, 12 V and 6-6.5 V for the Guide 10 branded charger. Next to the inverter is a patch pocket that can be used to arrange devices while they are being charged from the solar panel , and to store some accessories.
The Goal Zero Nomad 7 solar panel is operational year-round regardless of the season. Unpretentious and requires minimal maintenance. In order for it to start working, just by deploying it, orient it on the Sun and connect a consuming device to it.

The Goal Zero Nomad 7 solar panel is resistant to moisture, all its elements are protected, and eight rope half rings around the perimeter allow you to securely fasten the Nomad 7 on your backpack if you plan to use the panel to charge consumers while driving.
Charging batteries and batteries of electronic devices from the ports of the solar panel Goal Zero Nomad 7.
From the standard USB port of the Goal Zero Nomad 7 panel, you can charge all electronic devices that, by their technical characteristics, allow this charging method. In practice, charging the Samsung camcorder and Prestigio e-book was tested. Charging time is comparable to charging directly from a USB port on a computer.
Also, it is possible to charge batteries from the USB port of the Goal Zero Nomad 7 solar panel. For example, AA or AAA format. Charging time depends on the characteristics of the charger and the capacity of the batteries themselves. In our case, such as in the photo below (not the best option), the charger (charge current 1.2V 90-110 mA) fully charges AA batteries with a capacity of 2000 mAh in 21 hours. Such a time can hardly be called acceptable. Therefore, it is better to charge the batteries using the proprietary Guide 10 charger through a specially made output for it in the panel inverter. Or via a 12 V output using any compatible small-sized charger. Or using some kind of universal powerbank with battery function.
The adapter included with Goal Zero Nomad 7 connects to the 12 V panel output and makes it possible to charge devices with adapters for operation from the vehicle’s cigarette lighter socket. According to the test results, the charging time of four Eneloop AA batteries with a capacity of 2000 mAh, using the ATABA AT-998 charger, was just over five hours. Again, the charge time will directly depend on the characteristics of the charger and the capacity of the rechargeable batteries.
If necessary, the Goal Zero Nomad 7 solar panel allows you to use several of its ports to charge at once. For example, in our case, an e-book through a USB output and four batteries in the charger, through a 12 V output. In some cases, this can significantly save time..
