Travel gear and Electronics

I often get questions about travel gear and services I use while on the road, especially when people realize that all my possessions fit into a carry-on(ish) backpack. How do I manage to survive without X or Y? Do I really get by with just four pairs of underwear and three pairs of socks? (I do and for over a year I only had two pairs of socks until I realized that once I lose one, there will be only one left. True story!)

Here you will find some of my no bullshit reviews/thoughts on things I don't leave home without. Some of these I have been using for years while others just long enough to figure out that they belong in a trash can.
