A Dual USB Adapter is a device that allows you to charge or power two USB-compatible devices simultaneously from a single power source. It typically has two USB ports and can be used with wall outlets, car cigarette lighters, or even power banks.

How It Works:

1. Power Input: The adapter draws power from a power source such as an electrical outlet, car charger, or battery pack.
2. Voltage Regulation: It converts the power into the appropriate voltage (typically 5V) required for USB devices.
3. Dual Output: The two USB ports distribute power to two devices at the same time. Some adapters have smart charging technology to balance the power output based on the device’s needs.
4. Device Compatibility: Most dual USB adapters support smartphones, tablets, Bluetooth accessories, and other USB-powered gadgets.

Types of Dual USB Adapters:

• Wall Chargers: Plug into an electrical outlet.
• Car Chargers: Fit into a vehicle’s cigarette lighter port.
• USB Hubs: Expand a single USB port on a computer into multiple ports.
• Power Banks: Portable chargers with dual USB outputs.
