 Yeah, Juice Jack Defender, and I found it on Amazon for less than $6. And essentially what it is, it's a little USB-A to USB-A plug. Like a pass-through device. Yeah, a pass-through device. And what it boils down to is it doesn't have any wires inside it that allow data to transfer only power. So you can still charge your device, but there's no route in there by which data can pass in order to take data off your phone. Or to put a virus or data onto your phone, that sort of thing. So if you're traveling a lot, highly recommend that if you don't carry a battery pack, something to recharge yourself, then have one of these little devices for less than $6 plugged into the end of your charging cord for public.
