It Rokks

With the increasing use of smartphones and tablets for in-cockpit navigation comes the issue of keeping these devices charged, since running nav software will drain those batteries in no time. Scanstrut has come to the rescue with the ROKK Charge+, the first-ever waterproof USB charging socket. Not only is it IPX6 waterproof, it charges so quickly at 4.2 amps that you can run two devices while still building up battery reserves. $39.95. Scanstrut, scanstrut.com
