Warning: My $1,100 MacBook charger died in Lisbon and I learned why backups are not just for files
Two weeks into my stay in Lisbon my only charger fried and my laptop hit 4% at 11pm with a client call in 9 hours. I ran to three shops near Baixa and the cheapest replacement was 85 euros, which stung since I had already blown my gear budget for the trip. A hostel guy named Tomás lent me his spare and just said 'always carry two of the thing that keeps you working.' That night I finally set up a cloud backup and ordered a second charger, and honestly the charger was never the real problem, the real problem was me acting like my setup could not fail. So what is the one piece of gear you always double up on while traveling?
