Is 1500 watts better then 800 watts?

Answer 1

It really depends on what you are needing. If this is for an air conditioner or ceramic heater, you may not need one that big. If this is for an outdoor light to light an entire yard, you may want the bigger wattage. ■

Answer 2

In general, a higher wattage rating indicates a more powerful appliance. So, a 1500-watt device would typically be more powerful or produce more heat than an 800-watt device. However, the best choice depends on what you need the appliance for and your specific requirements.
