DIRECT POWERING OF MOBILE ELECTRONIC DEVICES FROM EXTERNAL POWER SOURCES

摘要

Mobile electronic devices can be made to ftinction using external electric power supply instead of the internal battery when the device is connected to an external power source. This has two benefits. One benefít is that mobile phones will not expíode even if they are used for calling while the mobile phone is connected to the external power source, as the battery is not used for calling when the external power source is connected. Second benefít is that the mobile device battery can be allowed to charge up from the external source or stay idle so that the device does not drain the charge of the battery as long as the mobile device has external power supply.
