Many modern mobile phones, smartphones, and PDAs can be charged from a computer's USB port (cable included). But, for example, Nokia smartphones have a separate charging connector, therefore, they cannot be charged in this way. For those who have a laptop, this is a big minus, because they won’t be able to charge their phone while traveling. But this is a fixable matter. Do something that the manufacturers of these phones haven’t thought of! Make your own USB charger!
