A plugged-in charger continues to consume electricity even when no device is connected. Although the consumption is low, it adds up over time, especially when viewed globally. There is also a certain safety risk, as inferior or defective chargers can overheat and even catch fire in rare cases.

Simple measures for energy saving and safety:

1. power strips with switches: a simple way to disconnect several devices from the mains at the same time is to use a certified power strip with a switch. This not only saves energy, but also increases safety.

2. unplug chargers after use: Unplugging the charger after charging reduces unnecessary power consumption and minimises the risk of overheating.

3. pay attention to the quality of the chargers: It is advisable to use high-quality chargers from well-known manufacturers. These are generally safer and more efficient than cheap no-name products, which often have safety problems.

4. battery care: To prolong the life of the smartphone battery, it is advisable not to charge the device to 100% every time. Many modern smartphones offer a function that stops charging at around 80%.

5 Use timers: A timer can be helpful to automatically disconnect the charger from the mains as soon as it is no longer needed.These simple measures can not only reduce energy costs in the long term, but can also improve household safety.
