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 the 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, which 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 a load. The input transformer steps down the AC power, and a rectifier circuit converts the AC components present into DC components. 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.

A power adapter is used to convert electrical power from one form to another to enable the proper operation of electronic devices. It typically converts AC (alternating current) power from a wall outlet to DC (direct current) power required by electronic devices such as smartphones, laptops, routers, and other gadgets. This enables these devices to receive the correct voltage and current they need to function safely and efficiently.

A power adapter converts AC power from a wall outlet into DC power for electronic devices, while a charger replenishes the energy of rechargeable batteries. Though sometimes used interchangeably, they serve slightly different purposes.
-
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 to be 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 adapter converts AC power from a wall outlet into DC power for individual electronic devices, while a power supply provides power to multiple components within larger systems.
-
There are currently 15 types of plug adapters in the world today and each is designed for specific regions and plug standards. The exact number of different power adapters can vary depending on factors like geographical regions, voltage requirements, and plug types. However, common types include adapters for North America (Type A and B), Europe (Type C, E, and F), the UK (Type G), Australia (Type I), and many others. Additionally, there are universal adapters that can accommodate multiple plug types, making them suitable for international travel.
-
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.
-
The EU adapters have a conductive tip measuring 9 mm in length and 4 mm in diameter with a rounded end. This is followed by a flexible insulated shaft measuring up to 10 mm in length and not exceeding 3.8 mm in diameter. The two pins are slightly angled and converge, with their centers being 17.5 mm apart at the tip and 18.6 mm apart at the base.
-
For Europe, the corresponding travel adapter is Type C, featuring two round pins. However, we advise you to verify the specifics for the destination you're traveling to by referring to our travel adapters page.
-
A Type C plug adapter is a travel adapter designed to accommodate Type C plugs, which typically feature two round pins. These adapters are commonly used in European countries and other regions with similar plug standards. They allow travelers to connect their electronic devices with Type C plugs to power outlets in various countries, ensuring compatibility and safe charging during international travel.
-
A Type C adapter typically refers to a travel adapter or plug adapter designed to accommodate Type C plugs. Type C plugs are characterized by two round pins and are commonly used in European countries and other regions with similar plug standards. Therefore, a Type C adapter allows you to connect electronic devices with Type C plugs to power outlets in different countries, ensuring compatibility and safe charging during international travel.

Your 20W phone will charge at the same speed with a 30W charger as it would with a 20W charger. The device draws power up to its maximum capacity. A 20W phone can draw up to 20W, which is what it would draw when connected to a 30W charger. However, your 20W phone will charge faster when plugged into a 30W charger compared to a 10W charger.
