The Sherpa 120 kit has been discontinued and Goal Zero has replaced it with the Sherpa 100 Kit, which we have not done a full review of. For now, we recommend you check out our review of the Sherpa 50 which is the 100's little brother; or, for a lighter more portable option, the Nomad 13. For the whole array of solar panels we've tested see our Solar Panel Review or keep reading to hear about the discontinued Sherpa 120.
The Goal Zero Sherpa 120 portable solar charger is a relatively light and durable portable solar kit that can charge just about anything. If you have a lot of electronic devices to charge and spend a fair bit of time away from a power source, this is the device to get.
That said, it is very expensive. If you just need to charge a cell phone, camera or other other small device, we recommend the Goal Zero Nomad 7 which is far less expensive and lighter.
