A portable public address system is not ideal for all school situations. This is because there are some disadvantages to this type of system. Specifically, battery life and battery charge time may be less than ideal. Although the ability to have a system which is portable can be useful in a variety of situations the use of the system is somewhat limited by the battery life. This becomes problematic when the public address system is transported to a locale where there is no access to a power source.
