The USBC-VAMETER and USBC-VAMETER3 display voltage, amperage, and the calculated wattage directly on the screen. To manually calculate the wattage (how much power a device is using), simply multiply the voltage by the amperage.

How to Calculate Wattage

The power (P) in watts (W) is equal to the voltage (V) in volts times the current (I) in amps (A), using the formula: P = V × I.

Example: If a device is charging at 20V and 5A, the calculation is 20V × 5A = 100W.
