Power Consumption of Electronics

Power Consumption of Electronics

I am recording some power consumption figures for electronic equipment.

Measured using Kill-A-Watt. Devices that fall below Kill-A-Watt's sensitivity threshold are measured alongside other devices to calculate their actual power usage.

Streamers & DACs Active watt Idle watt
Chromecast Audio 1.2w 1.2w
Topping E30 DAC (optical input) 2.1w 1.4w
Phorus PR5 2.9w 2.9w
WiiM Mini (optical output) 1.0w 1.0w
 
Amplifiers Active watt Idle watt
Shui Yuan original TPA3255 amp on Aiyima 32v power supply 4.6w 4.4w
SMSL DA-6 1.6w 0.3w
Fosi V3 w/ 48V 6.7w 6.7w / 0.8w*
Sony STR-DH190 22w 20w
 
Others Active watt Idle watt
Southsky 192khz HDMI ARC audio extractor 0.4w 0.4w
Dish Joey 8w 8w
Dish Joey Wireless 7w 7w
Echo Show 8 (gen 1) 4w 2w

*note: Idle watt measures the power consumption when a device is idle. Some devices can optionally be turned off, in which case we also measure the power consumption when turned off (phantom power draw)

Honeywell HPA300 Air Purifier: low speed 36w, medium speed 63w, high speed 82w

Honeywell 18155 SilentComfort Air Purifier: low speed 34w, medium speed 47w, high speed 71w
