No-load power consumption test
Whether the charger will waste power when not used in the socket, and how much power will be lost, this is the question in the minds of many readers, and the standby power consumption link is to answer this question. Plug the charger into the socket of the Becky power meter and read the data on the power meter, the test results are as follows.
After the power meter test, the no-load power consumption of the charger at 220V 50Hz voltage is 0.097W, which translates to a year's loss of about 0.849KW·h, and if the market electricity price is 0.6 yuan/KW·h, the charger's electricity cost for one year is about 0.5 yuan.
Let's look at the no-load power consumption at 110V 60Hz voltage, the power consumption read by the power meter is 0.059W, which translates to a year's loss of about 0.517KW·h, if the market electricity price is 0.6 yuan / KW·h, the charger annual electricity cost is about 0.3 yuan.
brief summary
After the above no-load power consumption test, the Anker 33W USB socket is not used when plugged into the socket in a 220V 50Hz voltage environment, and the electricity cost consumed in a year is about 0.5 yuan; while the 110V 60Hz voltage environment is plugged into the socket and not used, the electricity cost consumed in a year is about 0.3 yuan.
