Wall mount power supplies can be either AC or DC. They come in a range of configurations, depending on the scenario that they’re designed for.
Regulated – Regulated wall mount power supplies feature voltage regulators that ensure the output voltage remains consistent, never deviating from the rated value of power supply.
Unregulated – Unregulated wall mount power supplies differ in that their output voltage will decrease as the output current increases and vice versa. This means that the power supply must be matched as closely as possible to the voltage and current requirements of the device in question.
Linear – Linear wall mount power supplies convert high voltage AC into low voltage, this is then converted into DC voltage. Whilst these tend to have low efficiency, they are also more reliable and faster than switching mode power supplies.
Switching mode power supplies – Wall mount switching mode power supplies convert the input signal into DC before stepping down or up the voltage to the required level. These power supplies have high efficiency and are less bulky than their linear counterparts.

Depending on its configuration, a wall mount power supply will typically consist of a transformer, a rectifier, smoothing, a regulator and load. The input transformer steps down the AC power, a rectifier circuit converts the AC components present into DC component. The signal is then smoothed out by a filtering circuit. A regulator controls the voltage to the desired level, before leading to the load which uses the pure DC output from the regulated output.

Wall mount power supplies are used in a wide range of industries and applications. They can be designed for use with a full range of input voltages and can output to a similarly wide range of wattages. Linear wall mount power supplies are typically used in audio frequency applications due to their immunity to RFI. Meanwhile, wall mount switch mode power supplies are used in phone chargers and DC motors.

In order to choose the right wall mount power supply for your requirements, you need to first find out where your device needs AC or DC. You’ll usually find the power requirement on the device itself, look for the voltage requirements so that you can ensure you are providing the correct amount of power. Too much or too little power may lead to your device being damaged.

What is the Purpose of a Power Adapter? The power adapter serves the purpose of converting AC voltage to a single DC voltage for your computer. It operates as an external battery for your computer so that the computer's size does not need to be so large. A computer uses many different DC voltages.
-
In short - a Power Supply is intended to provide a constant voltage to static applications, whereas a Charger is designed to provide a continuously regulated current to mobile devices, which have an integrated Battery

The most common wall sockets in Italy are the EU standard plug type C, F but you may also find type L. Frequent travelers often have an all-in-one adapter that works all around the world, this would be suitable for all Italian wall socket types.
-
When considering a wall adapter, you need to know what type of voltage your device needs: AC or DC. You should also look for a recommended charging current listed on the device you are powering. From there, decide whether you want regulated or unregulated, and linear or switching.
-
An AC adapter or AC/DC adapter is a type of external power supply, often enclosed in a case similar to an AC plug. Other common names include wall wart, power brick, wall charger, and power adapter. Adapters for battery-powered equipment may be described as chargers or re-chargers (see also battery chargers).
-
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.

American devices with two prongs to the plug are known as Type A and American devices with three prongs are Type B. There are currently 15 types of plug adapters in the world today so you can see, a little research into your needs will save a headache, time, and even cost later on.
-
You may see adapters with three prongs in a row. That's because some, but not all, Italian outlets have three holes. Don't buy these. Instead, buy a 2-prong adapter, which should fit into most outlets with two and three holes.
-
They consist of a 9 mm long conductive tip of 4 mm diameter with a rounded ending, followed by a 10 mm long flexible insulated shaft of not more than 3.8 mm diameter. The two pins are not exactly parallel and converge slightly; their centers are 17.5 mm apart at the tip and 18.6 mm apart at the base.
-
For Europe, the associated travel adaptor is type C, which is the plug that has two round pins. However, we recommend you check the information for the destination you're traveling to on our travel adaptors page.
-
The Type C plug (also called the Europlug) has two round pins. The pins are 4 to 4.8 mm wide with centers that are spaced 19 mm apart; the plug fits any socket that conforms to these dimensions.
-
The USB-C to USB Adapter lets you connect iOS devices and many of your standard USB accessories to a USB-C or Thunderbolt 3 (USB-C) enabled Mac. Plug the USB-C end of the adapter into a USB-C or Thunderbolt 3 (USB-C) port on your Mac, and then connect your flash drive, camera, or another standard USB device.

Your 20W phone will charge at the same speed with a 30W charger as with a 20W charger. The device takes up to the wattage it can take. A 20W phone can take up to 20W, which is what it would take while plugged into a 30W charger. Your 20W phone will charge faster plugged into a 30W charger compared to a 10W charger.
