Finding an outlet at the airport can be a real sport sometimes. Especially, when people like to occupy the only one within 100 meters of your gate for the entire waiting period. Most people don’t really understand outlet etiquette. That is why you need this little guy in your bag. You can add 4 outlets to any outlet you can find. I am sure you can ask the friendly stranger to plug this in so you can both share. So unless you find an empty mobile charging station (which is rare) or have access to an airport lounge this can be a gadget battery life saver.
Its cheap too. Get it for about $6 + $5 for shipping.
