One-Click send to USB - Andriod

[Rippleman]

In April 2017, my mother is taking a 2 week trip to Machu Picchu. She is computer illiterate and I am trying to find a solution that will allow here to take as many photos and videos as she wants without having to worry about running out of space on her phone.  She does NOT know how to unload her phone into a computer - which I do every few months for her - and will not be taking her laptop because of the reason previously mentioned. So, here is the question:

 

Is there an app that specifically has a one-click "send my photos to USB" for android? I was thinking maybe just to send her with an andriod based handset with a external portable hard drive that she can plugin and press one button and have everything on the phone (camera) sent to it.  

If no app like that exists, I may just buy her 3 - 128 gig memory cards and teach her to swap out when full.

Just set her up with Dropbox, and enable sync, all the pictures will be copied to Dropbox as well as remain on the device.
