How Much Power Does a Projector Use

Many projector beginners wonder how much power a projector use. This guide will collect and conclude the common power of projectors available on the market, helping you to know the power consumption of common projectors.

How Much Power Does a Projector Use?

The power consumption is determined by the work and power of the device. According to the formula, Total Work Done (W) = Power (P) x Time (t). Generally, a portable projector or pico projector consumes more power than a big projector or complex projector. For projectors, the power consumption is determined by the optical machine, light engine, speakers, fans, and more.

If the light source of a projector is fixed, the higher the brightness, the more power consumption. That’s because the light output and heat dissipation require more power.

Then, let’s check the Power of common projectors for different types. We find popular projector models on the market for different types and chart them as shown below.

Portable Projectors

Emotn H1

Most portable projectors feature a small body and average configuration. Generally, they are small and lightweight, which is better to carry outside.

According to the table below, most portable projectors have 50-60W of power, which consumes about 0.05-0.065 KWh.

BenQ X3000i385 W0.385 kWh

Laser TV Projector

Epson LS500

As a TV replacement, laser TV projectors usually have high configurations, including high brightness, powerful speakers, excellent ventilation, and more. Therefore, the integrated power consumption is high.

Then, let’s see the laser TV projector’s power consumption. We can see the average power consumption is the highest in the list.

Projector NamePowerPower Consumption Per Hour
Epson LS500366 W0.366 kWh
BenQ V7050i480 W0.48 kWh
Hisense 100L9G TriChroma320W0.32 kWh
Samsung Premiere LSP9T410W0.41 kWh
