How much Chargers Do you own? We are surrounded by rechargeable electronic devices – Mobile phonesLaptops, smart watches, headphones, E-bikes And more.
You may have a phone charger plugged past your bed without even bothering it to turn it off the wall or turn it off when not being used. The same could look for a laptop charger by your desk.
But is that risky? And are there hidden costs associated with leaving chargers at all times?
What is inside the charger?
Of course, not all chargers are the same. Depending on the application and energy requirement, their internal structure can range from very simple for complex ones.
However, a typical charger takes in AC (AC power) from a wall plug and converts it to a low voltage DC (directly) suitable for your device battery.
To understand the difference between DC and AC, consider the electrone flow in the wire. In the DC circuit, the electrons range in one direction and continue to rotate in a circle. In the alternating circle, the electrons do not circulate and only move back and forth.
The reason why we use both types of electricity goes long way, to the time they invented Thomas Edison And Nicola Tesla struggled to which species would become the default standard.
Today we are still stuck between both. Electricity It is traditionally generated in alternating form, but modern devices and batteries require a DC form. Therefore, almost every electrical appliance comes with AC-DC converter.
To convert from AC to DC, a typical charger needs several electrical components such as transformers, a circuit for creating actual conversion, filtering elements to improve the quality of the output DC voltage and control circuit for regulation and protection.
Chargers spend strength even when they don’t fill
“Vampire Power” is real. If you leave it connected, the charger will continuously extract a small amount of power. The part of this power is used to hold control and protective circles, while the rest is lost as warmth.
When we look at the individual small charger, vampire forces – known as the power of standby – is negligible. However, if you perform with all chargers in your home for various devices, by time, lost energy can be significant.
Standby power is not exclusive for chargers; Other electronic devices such as the TV draw a little power in standby mode.
Depending on how much things you leave, during the year, it can take a few kilowatt hours.
It was said that modern chargers are designed to minimize standby consumption. These chargers come with smart power management components that keep them in sleep mode while the external device is not trying to extract power.
There are other risks
Chargers are carried out with time when electricity flows through them, especially when electricity voltage temporarily increases above their grade.
The electric network is a chaotic environment and various voltage events happen from time to time.
Leaving chargers exposed to these events will shorten their lives. This premature aging should not be alarming for modern devices, thanks to improved design and control. But especially refers to cheap, unintentional chargers. This often lacks the appropriate level of protection and can be a risk of fire.
How do I take care of the chargers?
Although modern chargers are generally very secure and should draw the minimum standby power, consider degross imposition, if convenient.
If the charger becomes hotter than usual, it makes noise or is damaged in any way, time to replace. And definitely should not remain connected.
