Appendix C. Typical Power Requirements
When creating your power analysis, you need to establish the power requirements for your system. The best way is to measure the actual power consumption using a watt meter.
Finding a ballpark figure for similar devices is the least accurate way of finding out your true power requirements. However, for an initial project analysis it can be a useful way of getting some information quickly:
