What do the numbers on the phone charger mean?

251 views

Input 100-120V-50/60Hz, 0.5A

Output 5V-3A/9V-2A/12V-1.5A

Input 200-240V, 50/60Hz, 0.7A

Output 5V-3A/9V-3A/12V-2.25A/20V-1.35A/11V-3A (Max)

I know what V, A, W are and that my charger is a 33W charger. How did they come to these conclusions? Please help

>11V-3A

That is how you get 33 watts of output. Its is 11 Volts X 3 amps.

All those input number are the power draws at a given voltage. At 100-120V-50/60Hz, 0.5A but at 200-240V, 50/60Hz, 0.7A.

So it will draw more power at 240V than at 120V.
