Power supplies are categorized in various ways, including by functional features. For example, a regulated power supply is one that maintains constant output voltage or current despite variations in load current or input voltage.
The common solution to this challenge is to use the mains regulated DC supply as a battery charger. With mains present, the DC supply will maintain/charge the battery and power connected peripherals at the same time. You need to regulate the DC supply output voltage to match the battery maintenance-charge level (about 13.7V).
If you are tired of replacing batteries in your portable radio or in any other battery-powered device, using an AC power adapter is a good alternative. All you need to do is to determine the voltage (V) and current

This doesn''t mean your device will consume 3.42 A when its powered with this adapter; it is only an indication of the maximum current that can be drawn through the adapter by any device that it is connected to, above which the adapter gets damaged. Any device will only draw as much current as it needs, so long as its power source can supply it.
The common solution to this challenge is to use the mains regulated DC supply as a battery charger. With mains present, the DC supply will maintain/charge the battery and
The amperage rating of a charger or power supply is the maximum it can supply. A device being charged will only take as much amperage as it requires. If your device needs 0.5 amps to charge, and your charger is rated at 1.0 amps, only
To convert battery-operated devices to work with an AC power supply, you need to use a power inverter, which converts DC power to AC power. You can purchase a power inverter from an electronics store or online. Once you have the power inverter, you need to connect it to the battery terminals of the device, and then plug it into an AC outlet.
While power supplies and battery chargers may seem similar in that they both provide DC power, they are not interchangeable. A power supply is designed to provide a continuous supply of power to a device, whereas a
This is a charging method where batteries are charged with a constant current from beginning to end. A standard switching power supply is
The fact that a device is "Under load" actually directly means that the device is simply using power or current from the supply. So, for any specific circuit, the heavier the Load becomes, the more current or power will be taken or drawn from the power supply. A circuit that is NOT under load is not drawing any power or current at all.
I currently have a set of charged lithium-ion batteries that supply power to the PC (20V / 100W) when in mobile mode. They last around 2.5 hours on continuous runtime. However, if I want longer runtime without shutting down the PC, especially when I''m continuously processing data overnight, I''d typically run on external power supply. 120V
