# What is a kVA ?

The kVA (kilovolt-ampere) is a measure of **power** similar to a kW (kilowatt) (1 kVA = 1000 VA)

Depending on whether you are in an AC (alternating current) or DC (direct current), one kVA will be roughly equal to 1 kW.

**1 kVA ~ 1 kW**

In fact, this is true for **DC currents** (not for AC currents), but there is no need to get too technical for you to understand the basic concept.

As discussed in our What is a kilowatt page, most appliances show the **power** consumption of the appliance in watts, or kilowatts. But in some cases, appliances might not show the power directly in watts. What they do always show is the **Amperage** (in Amps, or **A**), and the **Voltage** (in Volts, or **V**). You can see this on the image:

Here, in the output (in the wire going out of the charger towards the laptop computer), the Voltage is **19.5V**, and the Amperage is **3.34A**.

If you multiply these 2 numbers together, you obtain: **19.5V x 3.34A = 65.13 VA ~ 65 W.** This indeed corresponds to the **65 watts** indicated in the red circle on the photograph
