Abstract
A multimedia player having battery backup power has a housing, a battery seat, a rechargeable battery and a circuit module. The battery seat is formed on a periphery of the housing and has a battery connector electrically connected with a power circuit of a power module mounted inside the housing. The rechargeable battery is conveniently and directly mounted on the battery seat and supplies backup power to the power circuit of the power module through the battery connector. As the power circuit is connected with an AC power source, the power circuit further converts the AC power into DC power to charge the rechargeable battery when the AC power supply is normal, thereby reducing the frequency of battery replacement.
