Quickpost: Standby Power Consumption Of My USB Chargers

I did some tests with my USB chargers: how much power do they consume when plugged into a power socket without charging any device (standby)?

The devices I tested are:

  1. Apple A1357
  2. Apple A2347
  3. Anker A2053
  4. No-brand: Chacon EMP604USB

I connected each one to a powermeter and let it measure the standby power consumption for 24 hours.

This is the result:

Model24 hours (Wh)1 hour (Wh)1 year (Wh)
Apple A13572,88470,12021052,9155
Apple A23471,27230,0530464,3895
Anker A20535,07340,21141851,7910
No-brand: Chacon EMP604USB5,64730,23532061,2645

24 hours is the measured data, the “1 hour” and “1 year” columns are calculated based on the 24 hours data.

The no-brand USB charger consumes the most: around 2 kWh per year, which is still less than a switched off Philips Hue lamp.

Using the same cost as for the Philips Hue lamp, that no-brand charger costs me around €1 if I would leave it plugged in for a whole year without letting it charge anything.
