There are two options for using this solar kit. The best way to go is to charge the Switch 8 battery, which requires about 5 hours of direct sunlight. This battery can then be plugged into a small device, such as a phone, charging the phone in about 1 hour. You can also plug gear directly into the panel to extend the battery life of the device. The panel has a USB port and 12-volt plug-ins. The kit comes with a USB cable, but you will need a special plug for your own devices if they are not USB-compatible.
My favorite thing about the Goal Zero Switch 8 Kit is that the battery can hold the electricity for days, and charge your devices anytime (not just when the sun is out). It also doesn't hurt that the kit is rain-resistant, and the solar panels are protected in a sturdy nylon case with eyelets that allow it to be lashed down.
