Power adapters
Unless a circuit is battery-powered, an adapter must be connected to convert alternating current from the outlet into direct current. These 'wall-mount' power supplies are generally very compact, sacrificing some efficiency b ecause heat is difficult to dissipate and space for components is limited.The 3 most popular Power adapters

Which specifications are important?
Every power adapter has important specifications that directly affect its performance and compatibility with your devices. Here are the most important specifications you will find on an adapter and why they matter:
Voltage (V)
The voltage of your power adapter must match the voltage of your device. If it is too high, your device may break because too much current is flowing through it. If it is too low, your device may not get enough power to work properly. So always check first if the voltages match.
Current (A)
The amperage, expressed in amps, tells you how much current the adapter can handle. Make sure your adapter has enough amps for what your device needs, so everything runs smoothly and safely. Too little amperage can cause your adapter to fail.
Wattage (W)
The wattage, which is the current times the voltage. For example, if your adapter delivers 5V and 2A, then the wattage is 10W (5 x 2 = 10). This number is important because it tells you how much power the adapter can deliver at most. Make sure your adapter has enough wattage to handle your device without problems.
Polarity
Polarity is all about connecting the plus (+) and minus (-) correctly. If you do this incorrectly, your device can break. So always check the polarity symbol on both your adapter and your device before connecting everything.
Connector Type
The connector of your power adapter should fit seamlessly with your device. There are several types of connectors available, such as USB , micro USB and barrel jacks. For USB power supplies, see our USB power category for more options. Barrel jacks come in different sizes, but the most common type is often 2.1mm x 5.5mm. If your adapter doesn't fit, we have a handy DC plug adapter set that makes your jack compatible. Always make sure you choose the right connector to avoid bad connections or damage to your device.
The risks of cheap adapters
When purchasing power supplies, it is essential to choose a reliable brand instead of cutting corners with cheaper alternatives. Cheap, often Chinese adapters pose a real danger; they can cause overheating, short circuits and even fire due to non-compliance with strict safety standards. In contrast to these risky products, our Meanwell power supplies offer a safe and reliable solution. They have been thoroughly tested and meet international safety standards, ensuring a stable power supply. Investing in a Meanwell power supply means choosing safety, durability and efficiency, which protects you from dangerous situations and ensures long-term satisfaction and performance.
