Mobile devices without a charger are like people without air. But while air is (for now) a freely available commodity everywhere, chargers cannot offer "air" to mobile devices at every step. That's why you can do it with every turn of the pedal. But only if you use the Siva Cycle Atom ecological charger on your bike, which is created for all types of mobile devices and has a built-in battery that allows you to charge devices even when you are not on the bike.
