Most megaphones are portable in the sense that the average person can carry them unassisted. However, there are other megaphones that have patented built in amplifiers that are also used with wireless or handsfree microphones enabling the user to wear them on their person as opposed to shouting through a typical bullhorn. These devices are lightweight and rechargable.
