FAQ Power Supply

Are you thinking about buying a Power Supply used but are still undecided? Let's examine the advantages and considerations when buying.

How do you evaluate the energy efficiency of chargers and why is it important for the environment?

The efficiency of chargers is determined by the ratio of energy taken in (input) to energy given off (output). More efficient chargers convert more input power into usable output energy and lose less energy in the form of heat. This is important for the environment because higher efficiency means less energy is required from power plants, resulting in lower greenhouse gas emissions. Efficiency standards such as the Energy Star label help consumers identify the most environmentally friendly products.

For smartphones, laptops and tablets, there are mainly USB-A, Micro-USB, USB-C and Lightning cables. USB-C is currently the most efficient type as it supports faster data transfer and higher charging speed. It can also be plugged in from both sides and is compatible with a wide range of devices, from smartphones to laptops. Lightning cables are exclusive to Apple devices and offer similar benefits in terms of efficiency, but are only compatible with Apple products. However, fast charging damages the battery in the long term.

Solar powered chargers - how do they work?

Portable solar chargers use solar panels to convert sunlight into electrical energy, which is then used to charge devices such as smartphones, tablets, and sometimes even laptops. These devices come in a range of sizes and capacities, from small, foldable panels that are easy to carry to larger, more powerful units with multiple panels for faster charging. Efficiency depends on the size of the solar panels and the amount of direct sunlight. They are particularly useful for outdoor activities or in areas where access to electrical energy is limited.

How can you save electricity in everyday life and thereby reduce energy and costs?

How often do you leave your charger plugged in even when not in use? If the charger is left plugged in, even when not connected to a device, it will continue to use a small amount of power, often referred to as "idle consumption." This "vampire consumption" can add up over time, especially if multiple chargers are left plugged in at all times. It is therefore a good practice to unplug chargers when not actively in use to save energy and minimize environmental impact.

Here are other tips for saving battery life: reduce screen brightness, enable power saving modes, close apps running in the background, disable unnecessary push notifications, turn off Wi-Fi and Bluetooth when not needed, and regularly check battery usage to identify power-intensive apps. These simple steps can significantly extend battery life and reduce power consumption.

What do you do with old chargers?
