The days of having to carry multiple chargers are over. USB Power Delivery is a fast charging specification available as part of the USB Type-C connector standard, and has been incorporated into a wide variety of devices including smartphones, tablets, laptops and more. This means the same charger could be used to charge all these different types of device.
By talking to the device, a PD charger can determine how much power a device is able to receive, providing the optimal charge and no more, ensuring devices are safe from overheating. It even adjusts dynamically as the device charges, prolonging device battery health. This all happens automatically, with no input or management necessary.
Most modern smartphones are PD-compatible, including iPhone 8 and newer, and Samsung Galaxy S8 and newer. Many tablets, laptops, handheld games consoles and more support it too. PD requires a USB Type-C to Type-C cable, or a USB Type-C to Lightning cable for Apple devices.
