So, in this example, your 12 volt fridge uses a max of 60 watts. To estimate its max power consumption in watts, you multiply its voltage by its amperage. You look at its product specifications and see that it has a max current of 5 amps. Knowing a devices wattage is necessary for estimating how much power it's using at a given moment, as well as how much energy it consumes overall.įor example, let's say you have this portable 12 volt fridge. It turns out your panel is a 100 watt solar panel. To calculate the watts produced by the panel in full sun, you would multiply volts times amps. Let's assume you have own the following solar panel that is rated at 18.6 volts and 5.38 amps. Here's a simple example illustrating how to convert volts to watts. The conversion formula remains the same.Īlternate abbreviation: P = V × I Example Occasionally, you may also see watts abbreviated as P instead of W and amps abbreviated as I instead of A. To convert volts to watts, simply multiply volts times amps. 5 Volts to Watts Volts (V)Ĭonverting volts to watts is easy - you just need to know the current in amps. Sometimes there is even additional compatibility with types J, K and L.Here are some tables converting common AC and DC voltages to watts at various levels of current.

Whenever the electricity situation in a country requires additional information, the country name in question is highlighted in red. Obviously, this makes it very hard for travellers to assess what kind of plug adapter or transformer they will need for their trip. Many Latin-American, African and Asian countries, however, use a motley collection of – often incompatible – plugs and sometimes also the voltage differs from region to region. If you take a scroll down the page, you will notice that most countries have a well-defined plug and voltage standard.
