Purchasing guidelines for cordless and mobile telephones
Most offices have cordless and mobile telephones. Taken individually these devices do not consume much power, but if there are many the amount of wasted power can be significant.
Purchasing requirements for cordless and mobile telephones
Conform to Energy Star specifications for power supplies effective from 1 January 2005 combined with GEEA 2007 criteria for Standby.
| Equipment type | Standby (1) watt | No-load (2) watt |
| All | 1 | 0.5 |
The requirements apply to chargers and base stations for cordless phones and chargers for mobile phones for normal use in offices and homes. Power consumption is the maximum permitted for energy efficient equipment.
Notes and additional definitions
