I need to know and confirm some measurements regarding it so I can buy the proper battery. power adapter says INPUT: 100-240V @ 1A, OUPUT: 12V @ 2.58A So if I can somehow supply DC power (12V) directly from battery to the surface, it would draw
Understanding the power of a battery is important to determine the appropriate use of that battery and the rate and flow of current is one of the most important power factors that need to be considered. A high current battery is ideal for most usage and applications but needs to be fully understood to ensure appropriate usage practices. ...
Say there is a forced beta of 20 -- this means 0.01/20 = 0.5 mA of base current is required. This consumes 0.5 * 12 = 6 mW from the battery also. It is easy to see that base current drive power can be a larger problem than BJT dissipation itself. Also note this
