A 5V 1A charger refers to an AC to DC power adapter that provides a steady 5 Volts of electrical potential and can output a steady current of up to 1 Ampere. These chargers are common for small electronics, like smartphones, digital cameras, Raspberry Pi boards, etc. The specific charging power in Watt can be calculated by multiplying voltage and current, which is 5 watts in this case.
How it works:
- Connection: The charger is connected to a power source (typically through a standard household electrical outlet) and the device to be charged.
- AC to DC conversion: The charger converts the alternating current (AC) from the power source into direct current (DC) required by the electronic device.
- Regulation: The charger regulates the voltage and current output to ensure the electronic device receives a steady 5V and 1A power supply.
- Protection: The charger usually includes circuit protection to prevent short circuits, over-voltage, over-current and overheating.
It's crucial to use chargers with the appropriate voltage and current ratings for the electronic devices to avoid any damage or battery longevity issues.
