oops, it's more around the region of $5 per year...

30L dry cabinets are rated at around 4W, that makes (4/1000)*24*365=35.04kWh usage per year. Current elec. tariffs of $0.1656 will result in a elec. bill of $5.80 for a year's usage.

quite cheap lah. :sweatsm:

Whew.. I thought it's really $5/mth

If true, my parents will 'kill' me when I do get my dry cabinet in future.
The running cost of the cabinet will be more than half the price of the cabinet itself.
