Multi-Output Power Adapter for Efficient Device Charging
Here’s PatSnap Eureka !
Summary
Problems
Conventional power adapters do not efficiently supply different DC voltage levels to multiple electronic devices, leading to the need for multiple adapters, which are cumbersome to carry and confusing to manage, especially when traveling with various portable devices.
Innovation solutions
A power adapter with a DC-to-DC converter and multiple outputs that can supply different DC voltage levels, optionally integrated into a connector cord, along with relays for intelligent voltage control to ensure compatibility with connected devices, allowing power to be supplied to multiple electronic devices using a single adapter.

Specific contradictions:
General conflict description:
Principle concept:
If a user purchases a separate adapter for each electronic device, then each device can be powered with its specific voltage requirement, but the user must carry multiple adapters which increases bulk and complexity
Why choose this principle:
The power adapter is designed with multiple output ports that can simultaneously provide different DC voltage levels (e.g., 5V, 12V, 19V) to support multiple types of electronic devices including laptops, tablets, and smartphones. This multi-functional design allows a single adapter to replace multiple device-specific adapters, resolving the contradiction between voltage compatibility and device complexity
Principle concept:
If a user purchases a separate adapter for each electronic device, then each device can be powered with its specific voltage requirement, but the user must carry multiple adapters which increases bulk and complexity
Why choose this principle:
The adapter incorporates intelligent control circuitry that dynamically detects the connected device type and automatically adjusts the output voltage and current parameters for each port. This dynamic adaptation capability enables the adapter to provide appropriate power settings for different devices without requiring manual configuration or multiple fixed-voltage adapters

Abstract
An apparatus for providing power to an electronic device may include a power input configured to receive an input voltage from a power supply, and a rectifier operatively connected to the power input and configured to convert the input voltage to a first voltage. The rectifier may further be configured to transmit the first voltage to a first power output operatively connected to the rectifier. The apparatus may further include a power converter operatively connected to the rectifier and configured to convert the first voltage to a second voltage different than the first voltage and a first relay operatively connected to the rectifier to selectively prevent the first voltage from being transmitted through the first power output. The power converter may further be configured to transmit the second voltage to a second power output operatively connected to the power converter.
