What are power bricks? Help me know more…

Asked By Kevin A Augustin 40 points N/A Posted on - 05/28/2015

When we think about wireless charging, our mind says no wire needed. Is there any need to carry a power brick? I mean, will laptops automatically start charging? Will this technology be available to cafes, restaurants, airports and other public places? Can laptops be recharged without power adapters?

If you have anything else to share about power bricks, please share…

What are power bricks? Help me know more…

Power bricks are referred as transformer. It is a device to give an external power supply to a laptop or a notebook. It used in conjunction with a battery pack. Since notebook computers depend on low-voltage DC supply, they need a way to convert the AC from a power source into DC that can be safely used by the computer. The power brick takes the AC voltage and converts it to a DC voltage slightly higher than the battery (the slight elevation in voltage ensures that the battery stays fully charged). Batteries normally supply the safe DC voltage to the portable computer, but power bricks are intended for use in conjunction with or instead of a mobile device battery.
