A 5V 1A adapter refers to a power supply that outputs 5 volts of electrical potential and can provide a maximum current of 1 ampere (A). It is commonly used for powering devices that require 5V and a current draw of up to 1A.

Common Uses:

• USB-powered devices: Many gadgets such as smartphones, tablets, power banks, and other electronics that use micro-USB or USB-C charging ports often require this type of adapter.
• Arduino boards: Many microcontroller-based boards (like Arduino) use 5V 1A adapters for power.
• Small electronics: Devices like Bluetooth speakers, wireless routers, and LED strips.

Key Specifications:

• Voltage: 5V (volts) is the output voltage, typically used for USB-powered devices.
• Current: 1A (ampere) is the maximum current the adapter can supply, meaning it can safely power devices that draw up to 1 ampere of current. Exceeding this may damage the adapter or device.
