How can I backup my RAW photos while travelling without Internet access?

Disclaimer: long question.

While this covers the grounds of this question I would like updated awnsers, since some of the devices listed there are not available any longer. FUrthermore I would like to get some more information on the devices themselve and the experience you made with them.

The basic situation:

  • need to backup pictures on the go without a laptop/netbook/smartphone
  • would like the solution to be powergrid independent (battery powerable)
  • have a lumix g camera and shoot raw => picturereviewing only valuable if rw2 format capable
  • would like to have some visual confirmation of backup/copying success, since I might reuse my memory cards for further shooting (=> backup becomes only copy)
  • need SDHC card slot
  • weight is an issue
  • looked for usb bridges/usb on the go devices but they seem to have stopped those back in 2010.

For some of the devices I consider I did not find the manufacturers site, so I have only lacking amazon product descriptions. I would like to have the links to the datasheets/usermanual were I could not find them, know if the device supports rw2 (maybe list other raw formats for owners of different cameras?), supports creation of subfolders (not that important), and upsides/downsides.
