Electric Tether

It used to be that when you traveled with a camera, you didn't need much more than a supply of film. Batteries for light meters and such used to last 6 months to a year and if you remembered the Sunny 16 rule, you could get by without that. If you ran out of film, everyone used to carry it, even the local drugstore on the corner. If you needed something special, there was usually a camera store someplace around that carried it.

Now when you travel, especially for more than a day or two, you need an outlet nearby. The camera batteries need to be recharged, the laptop needs to be plugged in and batteries for other electronic devices need to get topped off also. Plus, since each device uses a different way to charge, you need to carry a lot of different chargers also.

I'm not sure this is really a great advance at times....
