Power banks charge your electrical gadget on the go. Select battery capacity, maximum current per data output, and connector type. A higher battery capacity allows you to charge the gadget longer. The voltage indicates how fast it can be charged (preferably 2A or higher). Weatherproof models are good for rain, and a portable battery can be solar-powered.
