Direct current (DC) occurs when the current flows in one constant direction. It usually comes from batteries, solar cells, or from AC/DC converters. DC is the preferred type of …
Diagram Depicting Battery System Output Power. If a high-power demand accrues that is greater than the capability of the input power supply, the input current limit resistor shown in red above can be sized to allow supplemental power to be supplied by the battery. This is convenient when occasional surges are expected but do are not sufficient ...

DC Power Supplies: What They Are And How To Use Them
Next, connect the power supply''s negative (-) output terminal to the negative input of the load or circuit. Double-check the connections to avoid reverse polarity, which can damage your equipment. Setting the Voltage and Current: Turn on the power supply and set the output voltage to the desired level using the voltage control knob or …
acceptable bounds for replacement DC adapter [duplicate]
However, without additional information, you can almost always replace one power supply with another that has the same voltage output with an equal or greater amperage output. Given that the output voltage is not standard, though, I suspect the adapter plays a role in charging that might not be replicated by a generic adapter.

Power Management, Chapter 1: Power Supply Fundamentals
Voltage Regulator ICs. Regulating the output voltage of virtually all power supplies is dependent on voltage regulator ICs. These ICs obtain a DC input from rectified AC or a battery.
Battery Charger -> Battery -> DC-ATX PSU. For example HDPlex DC-ATX. This way you''ll have a regulated power supply with sleep state support etc., but you won''t have any battery status stuff in Windows. For a short power outage that''s no problem, in a longer outage you may discharge the battery too far if you don''t add protection.
