iPad adapter specs: Input: 100-240V~ .45A (.45A) 50-60Hz Output: five.1V-----two.1A
I realize what all of the above mean even so I am unsure what the existing reading among brackets following the present rating to the left of that indicates. Please aid me.
Very best answer:

Your input adapter specifies that it may use any voltage between 100 and 240 volts AC, which you already know. The voltage, which is alternating present (household power), may possibly be supplied among 50 and 60 Hertz, or cycles per second. The United States operates on 110-120 volts AC at 60 Hertz, while the UK and most of Europe use 220-240 volts AC at 50 Hertz. Plainly put, your adapter is safe to plug in virtually anywhere in the planet without problems.
The .45A indicates that the adapter will draw .45 amperes of existing. This number is essential when plugging your adapter into a power strip with other devices on it, so that you do not overload the circuit and cause an unsafe condition. Most wall outlets worldwide will handle 15 amperes of present, and power strips normally will handle ten to 15 amperes, so you should be fine as long as the power strip isn't loaded up with too many devices. You can use the amperage and the voltage to figure out the device's power consumption in watts, which will tell you how a lot power your adapter (and iPad) will use. Multiply the .45A by the voltage where you will be plugging it in. In the US, the typical household voltage is 115 volts AC, so 115 x .45 = 51.75 watts, less power than the average light bulb consumes.
The final numbers are, as they claim, output voltages and amperage for your device. The adapter gives two.1 amperes of present at 5.1 volts DC, which functions out to ten.71 watts. That is fairly inefficient when compared to the 51+ watts of input power, but ten.71 watts is plenty to charge a device speedily and deal with any power consumption from employing the device while plugged in.
So, the final verdict is that your adapter can be used anywhere worldwide, consumes a fairly negligible quantity of power, and supplies a excellent, robust output for charging your iPad and using it whilst plugged in. You have nothing to be concerned about plug it in anywhere freely and take pleasure in.
