Ever been in a situation while camping or on vacation and your smartphone/tablet ran out of battery? Perhaps you wanted to stream content off of a USB stick but couldn’t. Well the RAVPower RP-WD-01 is probably what you’ve been looking for. This tiny little device has a 3,000mAh battery to recharge your smartphone/tablet, works as a portable router and NAS. See what I’m talking about in the video below in which I unbox and review the device.
