what is the difference between power supply and charger?
2894
A power supply is designed to supply a constant voltage to a load. ... A true battery charger generally supplies a regulated current, first to charge the battery, and then switches to a regulated voltage mode.

There are two ends to a power supply cable: The device-side and the PSU-side. The device-side of all PC cables is standardized. ATX 24-pin, EPS12V, PCI-e to the GPU, SATA—the wiring is known, and it doesn't change. What isn't standardized, however, is the layout of the PSU-side modular cable headers.

UPS vs Power Conditioners An Uninterruptible Power Supply (UPS) – is a device with a backup battery that provides several minutes of power in the event of a blackout. ... A Power Conditioner – is a device which filters and distributes power to various types of electronic gear such as studio monitors or audio interfaces.

A power supply for electronic devices. Also called an "AC adapter" or "charger," power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and the power adapter is the external part of the power supply for a laptop.

Battery requires direct current (DC) for charging. Mobile phone charger use switched mode power supply (SMPS) to convert AC supply of 120/24,50/60Hz to into DC supply such as 5V, 1.6A. In SMPS, input voltage from AC mains is directly rectified and filtered using a capacitor.

A Switching Power Supply has a lighter and smaller packaging than the linear power supply, the switching power supply offers the same power rating as the linear. ... This power supply converts the AC source to a high voltage, which in turn, is used to produce a DC current and voltage.

2 Answers. No, but you can find universal laptop chargers online that are pretty cheap. Look for one that has the same power rating as your current charger (i.e. 60W, 90W, etc.) and one that has a tip that matches the one you've got from Asus and you're all set.

Not any charger since the charger port might not fit, but most laptops use the same cpu's and other hardware, running the same voltages.

The time to charge the phone increases. ... Charging from a USB port of a computer is usually slower than charging using a charger because the voltage and amperage provided by the computer is considerably lower than in the case of using a normal charger, so the mobile is using “slow charge mode”.

Current is supplied by a power supply or charger. ... It will try and take as much current as it needs. So if a product requires 2.1Amps then the power supply should be able to supply 2.1Amps or more. If the power supply can supply more than 2.1Amps this doesn't matter as the product will only take 2.1Amps.

An AC power supply typically takes the voltage from a wall outlet (mains supply) and uses a transformer to step up or step down the voltage to the desired voltage. Some filtering may take place as well. In some cases, the source voltage is the same as the output voltage; this is called an isolation transformer.

A power supply unit (or PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. ... While an ATX power supply is connected to the mains supply, it always provides a 5 Volt standby (5VSB) voltage so that the standby functions on the computer and certain peripherals are powered.

Connect the Micro-USB cable to the Micro-USB Input of the PowerPack. 2. Plug the USB Connector of the Micro-USB cable into the USB port of your PC, Mac, or a USB compatible wall charger. ... The LED display will show the battery charge remaining on the portable charger.

Fully Modular PSUs. The main difference between the different types of PSUs lies in how they treat their cabling. Non-modular power supplies have all cables permanently attached. Semi-modular power supplies have some cables attached (the most important ones).

See, the default power adapter that comes with the iPhone 6 and iPhone 6 Plus provides a 1 amp (5 W) power supply. But your phone will charge faster if you connect it to a 2.1 amp (12 W) supply instead, like the type that comes with the new Apple iPad Air.

Switching power supplies are designed for high efficiency and small size. They incorporate a switching regulator to convert electrical power efficiently. Switching DC power supplies regulate the output voltage through a process called pulse width modulation (PWM).
