The 'Sherpa 15' is a high-tech series of power banks, offered by Goal Zero, that are designed to make it possible for you to charge different kinds of devices on the go at maximum speed and convenience.
This particular range of power banks comes with a trio of embedded cables that include micro USB, USB-C and Lightning. The device can be used in conjunction with a wall socket, although it is also more than capable of harnessing solar power when hooked up to a solar panel. These flexible functions are all the more impressive when you consider that the gadget costs only $49.50.
Despite all these features, the Sherpa 15 is also exceptionally lightweight, durable and rugged, making it a low-profile and high-performance option for anyone looking to charge their phone on the go.
