I found that at a 12.0 volt supply, the AstroZap AZ-813 heated dew shield drew only 12-13 watts (compared to the 21 watts in the specifications). This might be because I was testing it at 80 degrees ambient temperature, or perhaps the 21 watts are drawn from a 13.8-14.5 volt "Auto 12 volts" supply.
I did not get any dew on my lens that night, so I'm not complaining about the lower the specs power draw. [At 8 volts, it draws 5-6 watts.]
In this video I show a thermal camera view of the heatshield, both alone and on my LX-200 12" SCT, as well as the RCA to 5.5x2.5mm barrel connector adapter cable I made to allow it to plug into my photography light accessory batteries.
