Rechargeable batteries are now popular for most electronic devices, commonly known as handheld, mobile or portable. These devices operate on low voltage power, usually under 5 Volts (V) DC (Direct Current) via USB charging through the mains plug AC/DC converter.
iPads
iPads use 4.97 volts (V) and 2.1 amperes or amps (A) of power.
Android Tablets
Android tablets use 5 volts, 2.1 amps and 10.5 watts of power.
Notebooks
Notebooks (generally speaking) use a 220-250 Volt AC (Alternating Current) input from standard home wall socket power supplies, which are converted to 19 volts DC (Direct Current) into the notebook, which is then again converted down to 5 volts for usage across the mainboard.
Desktop and Server Computers
Most desktop and server computers or mounted racks, operate on the standard 220-250 volts D.C. and run on mains power - usually 220-250 Volts AC (Alternating Current) power. Power supplies are fitted inside the computer case housing, usually near the electrical socket. Knowledge of safety and electronic wiring are important, so that you do not get hurt or break your computer.
