Travel Power Strip
If you're staying at a hostel, then you will know there's usually a fight for available sockets in the common room. And sometimes they're in uncomfortable spots that are far away from any couches or tables. With this extender you can just plug it into a socket, connect all of your electronics, and drag it over to the couch. The same goes for a hotel room with a socket far away from the bed.
