I've been looking for something like this for a while. It's a USB bridge that allows me to copy files from one device to another without using a computer. It works by dumping all files on the one device into a storage folder on the other device. It's quick and small enough (cigarette pack sized) I can carry it in my camera bag. The biggest drawback is it dumps everything from the input device onto the output device. You can't do a partial copy.

My idea is to carry it on trips with me. Each day, I could copy the pictures I took onto another card or memory stick. I hate the idea of having all my vacation pics on one card without having backups. This could work for a backup with out needing access to a computer.

My testing shows it to be quick enough, but I only tried a few pictures.
