1. The only way to compare power consumption across multiple dongles is to measure it yourself using something like this or this.Thanks! I think I almost have all the info I need before choosing the dac/amp to use with my iPhone! The last thing I want to figure out is power consumption. Do you know how I could compare the power consumption between the Linsoul E1DA 9038S Susumu 3000 Gen3 (4 vrms), Luxury & Precision W2 (4 vrms), HIDIZS S9 PRO (4 vrms), Tempotec Sonata E44 (4 vrms), and DDHiFi TC44B (2 vrms)? They all seem to consume about 4 vrms except for the DDHiFi. Is this the figure that I need to look at in order to figure out which of these would drain my iPhone the quickest?
cheers,
Jon
Alternatively you can search for measurement reports from others. The 9038SG3 draws 90mA=0.45W.
2. "2Vrms/4Vrms" is the maximum output voltage of these dongles and is in no direct correlation with their USB power consumption. The power consumption is measured in ampere or in watt.
Please do not confuse these two specs.
