What to consider before you buy a television

television buying guidePurpose

Televisions may be categorized by the size of their screen, and the display technology they were built with. These factors usually affect the cost of the television as well as its power consumption. Televisions with older display technologies (example, CRT televisions and Plasma televisions) will generally require more electricity than those with newer technologies (example, LED and LCD televisions). Additionally, the larger the size of the television screen, the higher its power consumption.

Our advice is to buy your television from a trusted dealer, while considering its power ratings to inform your decision.

Power Consumption

In general, the power consumption of televisions vary based on the display technology used, the build quality, the size of the screen, what the display is showing (moving or static pictures), the brightness of the screen and if power saving settings are activated. The table below shows the average wattage of televisions based on their display technologies and screen sizes.

Always remember to check for warranty. The duration of the warranty determines the confidence the manufacturer has in the product. Therefore the longer the warranty, the more confident the manufacturer is that the product is durable. Never buy an appliance with no warranty! Finally, you should buy from an authorized dealer to ensure that the warranty is valid.


There are many electric kettle brands in the market. Always check for the SONCAP and the warranty certificates (as said above).
