Do I need a step-down transformer?

Do I need a step-down transformer?

You will need a step-down voltage transformer if you’re traveling to any country with a power standard that is higher than what your appliances use. Conversely, taking appliances that run on 220–110 volts to the U.S. or Canada requires a step-up voltage converter that can transform 110–120 volts up to 220–240 volts.

How do I know what transformer to use?

On the back of your appliance, you should be able to find a label describing its specifications including its Wattage (W) or the Amperage (A) of the appliance. Example: If your appliance consumes 80 Watts then you need a AC-100 transformer (100 Watts capacity) or higher.

What is a power transformer used for?

A transformer is an electrical device that trades voltage for current in a circuit, while not affecting the total electrical power. This means it takes high-voltage electricity with a small current and changes it into low-voltage electricity with a large current, or vice versa.

Do transformers consume power?

It turns out that these transformers consume power whenever they are plugged into the wall, whether they are connected to a device or not. They also waste power when powering a device. The power consumption is not large — on the order of 1 to 5 watts per transformer.

Can I put a UK plug on a 110V tool?

In the UK you need a 110v transformer powered tools because the only corded power tools you can use on the building site are 110 volt as well (battery tools are all OK).

Why do I need a converter to use my TV in Europe?

To answer your question, Europe does not use the same electric system as the US . We use alternating current, they use direct, therefore you need a converter to use your TV. However I would also check with the manufacturer’s recommendations to see if the TV might be damaged even with the converter.

Can I use my American TV in Europe?

Yes you can, but it might not be much use! Firstly, most of Europe use 220–240V not 110–120V like the US. This would mean you need to use a voltage converter to use it. This will probably set you back $50–100 for a good one, and you probably need a good one if you leave your TV on for hours.

How much does it cost to run a flatscreen TV?

As TVs continue to become more energy-efficient, the cost of running a flatscreen TV is only a few dollars a month. If you’re looking into upgrading your TV, consider choosing an LED TV and opting for a smaller screen size to reduce power consumption.

Do plasma TVs use a lot of electricity?

Plasma is the most energy-intense screen technology. Even a simple 30-inch plasma screen TV can use more than 150 kWh of electricity per year. A giant 50-inch plasma-screen TV will gobble up more than 300 kWh per year, costing you nearly $100 in Massachusetts. Experts agree: Choose LED for better energy efficiency.
