In this talk I will show how easy it is to measure the power required to operate all of our typical astronomy equipment from mounts and pcs to dew heaters, camera coolers and everything in between. I will also review the different types of lithium power sources which are becoming very popular among amateur astronomers from all-in-one solar generators to stand alone simple batteries. We will examine the differences between LiFePO4 and LiNiMnCoO2 chemistries and prismatic versus cylindrical battery cells. I will also share the results of nearly two years of testing a number of different lithium based solar generators and stand alone batteries to see how well they operate in the field, the different requirements for recharging each with solar panels and the pros and cons of each type.
