12V to 24V DC converter with 2 USB jacks for mobile charging application

A 12V to 24V DC converter with 2 USB jacks for mobile charging applications would involve a step-up (boost) converter to increase the voltage from 12V to 24V. The converter would then have USB output ports that provide 5V, which is suitable for mobile phone charging. Here’s a general overview of what such a device would include:

Key Features:

1. DC-DC Boost Converter:
   • Converts 12V DC (from a car, solar panel, or another 12V source) to 24V DC.
   • The converter typically uses a step-up (boost) circuit with an inductor, capacitor, and switching transistor.
2. 2 USB Charging Ports:
   • Each USB port would output 5V DC, which is the standard for charging mobile devices.
   • USB ports may support higher current outputs (e.g., 2.1A, 2.4A, or 3A) to charge smartphones, tablets, or other devices.
   • The USB ports would likely include over-voltage, over-current, and short-circuit protection to ensure safe charging.
3. Input/Output Specifications:
   • Input: 12V DC (automotive or other 12V sources)
   • Output: 24V DC for powering 24V devices or applications
   • USB Output: 5V DC (for each USB port, typically 2.1A to 2.4A for charging)
4. Efficient Power Conversion:
   • The boost converter should be efficient to minimize heat generation and maintain the ability to charge devices properly.

Application Use Case:

• Vehicle Charging: You could use this device in a car or truck to provide 24V for other devices while also having 5V USB ports for charging mobile phones, tablets, and other small electronics.
• Off-grid Solar: It can be used in a solar power setup where you have a 12V battery bank and need to power 24V appliances while also charging mobile devices.
• DIY Projects: This setup could be used in custom electronics or power supply projects requiring 24V power, with convenient USB ports for everyday use.

Example of the Setup:

• 12V Input (such as from a vehicle’s battery or a 12V solar panel).
• DC-DC Boost Converter to increase voltage from 12V to 24V.
• 2 USB Charging Ports providing 5V, suitable for charging devices like smartphones, tablets, or other USB-powered electronics.

Possible Considerations:

• Heat Dissipation: DC-DC converters generate heat, so adequate ventilation or a heatsink might be needed for optimal performance.
• Current Rating: Ensure that the converter is capable of handling the current required for both the 24V output and the USB outputs. A typical mobile device charging via USB might require 5V at 1-2A, so consider a converter that can supply the required power.

If you’re looking to buy or build such a converter, there are modules available on the market that integrate the DC-DC boost converter and USB charging ports in one package. Alternatively, you can also assemble the parts (a 12V to 24V converter, USB charging module, and necessary protection circuits) if you prefer a DIY approach.
