FAQ
How much does a smartphone charger consume?
A phone charger typically has a power rating of 5 to 15 watts. The power consumption is calculated using the following formula:
Power consumption (watts) = Voltage (volts) × Current (amps)
If, for example, a phone charger supports a current of 2 amps, then its power consumption is:
5V × 2A = 10 watts.
Some chargers may have an efficiency below 100%, which means that some of the energy consumed may be lost as heat. However, the total energy consumption remains approximately at the level of the specified power.

If your smartphone supports fast charging, make sure that the charger you choose also supports this technology (for example, Qualcomm Quick Charge or USB Power Delivery).
- Pay attention to safety. It is best to buy a charger with overload, overheating, and short circuit protection.
Also pay attention to the brand - reputable manufacturers offer chargers with a warranty.
