uNu Exera System Battery Case and Duo Charging Dock

Red battery statuses are shepherded into greener pastures by a lithium-polymer battery that’s built into the back of each hard-shell case. The two-piece case adds up to twice as much battery life to an iPhone 4/4S, resulting in an additional 6 hours of talk time, 30 hours of music playback, and 240 hours of standby time. A panel slides over the battery slot to keep the case uniform so phones can slide into front pockets or saint bernard casks. The clever case still allows for full functionality, and its rugged bumpers protect devices from nicks and scratches. Included in the system are two additional battery modules and a sleek charging hub capable of simultaneously powering three Exera battery modules and an integrated iPhone battery.
