Need to prepare the answer to this question which my "home minister" is likely to ask.
For instance, the Digi-Cabi AD-060 has the following specs:
Effective Capacity: 60L
External Dimension: W35 x D31 x H55cm
Power Consumpiton: 5W
Singaporepower.com.sg charges 16.73c per kWh. so the monthly electrical cost is...??
Sounds like a maths test paper...
