Frequently Asked Questions

How do you convert Watts into units of electricity consumed?
Electricity consumption is calculated in kWh (Kilowatt-hour). In our example, the Philips OTG has a rated power of 1500 watts. It translates to 1.5 Kilowatts consumption. In terms of power consumption in units, it amounts to 1.5 units per hour. Accordingly, you can calculate the monthly consumption and the effect it has on your electricity bill.
Is it advisable to purchase an OTG with higher rated power?
It depends on your preferences. The OTG with a higher rated power consumes more electricity if it runs for the same duration as an appliance with a lower power rating. However, the higher-rated OTG consumes less time for preparing the same food. Hence, the power consumption balances out. Besides, the more advanced the OTG, the more its features are.
