You find yourself on location — far from the nearest store — and you fill up your SD card. What do you do? Do you delete takes you think aren’t good enough? Worse yet, what if your phone runs out of battery? The Western Digital My Passport Wireless Pro is a wireless, battery-powered hard drive that can unload your SD cards while on the go, alleviating the need for more SD cards. To boot, its 6,400 mAh battery will charge your devices over USB. The Wireless Pro is a little black square with some blue lights, a SD card slot, a power button, a unload button, USB and micro USB 3.0 type B inputs/outputs. The unit we reviewed has a capacity of 2TB.
