Aquick usb charger claims its output current is 1.97amp. we know that the standard usb output voltage is 5v. what is the output power of the charger in unit of watt?

Output power of the charger is 9.85 watts.

Explanation:

It is given that,

Output current of the USB charger, I = 1.97 A

The standard USB output voltage, V = 5 V

We need to find the output power of the charger. It can be determined using the following formula as :

P = V × I

P = 9.85 watts

The output power of the charger is 9.85 watts. Hence, this is the required solution.
