But do study boost converters online and try making one in a simulation software. Thats ignoring the losses in the converter. 12V at 0.23A means you will have 0.552A at 5V. The current drawn from the 5V supply will go up by that same factor of 2.4. If you use a boost converter to get 12V from 5V, then the converter will have to boost the voltage by a factor of 2.4. If you have interest you may want to learn about designing a boost converter but that is a discussion for another day and has its own challenges. You have a 12 volt fan that will draw 0.23 amperes. Also remember boost converters aren't really happy when you apply zero load to their output, and this of course depends on how well they have been designed, the output voltage may increase to a large value. So in reality you can extract very limited amount of power from your converter. So now you know you can get 12V DC from 5V DC but as you increased the voltage, the output current must reduce to respect conservation principle. These boost converters feature a variable potentiometer that allows you to adjust the output voltage and get 12V DC. 95 depending on design and load you apply. It is recommended that you check for proper clearance between the switch bodies prior to purchasing these rockers. These rockers are slightly wider than the switch body by 3/64 of an inch on each side. Typical boost converters on Amazon would given you an efficiency between. OTRATTW Contura custom laser-etched and ink printed rockers are compatible with all Carling Technologies V-Series switches, incl. But we all know the law of conservation of energy, the amount of power that goes into the converter must be equal to the amount of power that goes out. To get 12V DC from 5V DC you need to use a power converter. For PCs it wouldn't really be wise to extract any more then 1 ampere without protection to avoid a very costly motherboard repair for your PC. It could go up to 3 amperes for very powerful socket USB charger. Before attempting the project, lets evaluate the power budget available to ensure the USB port responsible to supply power won't get damaged.Īs you may know the power that a typical usb port can provide is \$P = V \times I\$ where V is 5V and I varies depending on how powerful the source is.
