WIFI 120 volt AC run on 12 volt DC

In summary, the conversation discusses using a $10 WIFI unit from China that runs on 120 volt AC and wanting to make it run off of a 12 volt DC car battery. The idea of using a fixed regulator or a 12V inverter is suggested, but caution is advised when opening up the unit and modifying it. Using a DC to AC power inverter is also mentioned as an alternative solution.

I am getting one of those $10 WIFI units from china runs on 120 volt AC and I want it to run off of 12 volt DC car battery I am thinking will need to open up unit and try to figure out what the DC voltage is that is coming from the AC supply unit and then insert a fixed regulator of 12 or 5 volt or whatever the DC voltage may be.

You can buy inexpensive 12V inverters that produce 120 VAC. Will that do it for you?

That's a good idea, but be careful when opening up the unit and messing with the electronics. Make sure you have the proper knowledge and equipment to handle it safely. Also, keep in mind that modifying the unit may void any warranties or support from the manufacturer. Have you considered using a DC to AC power inverter instead? That way, you wouldn't have to tamper with the unit and risk damaging it. Just a thought.
 

1. How does WIFI work on 120 volt AC when it runs on 12 volt DC?

WIFI uses radio waves to transmit data, so it does not require a specific voltage to function. As long as the device has a stable power source, it can operate on different voltages, including 120 volt AC and 12 volt DC.

2. Can a WIFI device be powered by both 120 volt AC and 12 volt DC?

Yes, some WIFI devices have the ability to be powered by both 120 volt AC and 12 volt DC. This is often achieved through the use of a power adapter or converter.

3. What is the difference between 120 volt AC and 12 volt DC?

The main difference between 120 volt AC and 12 volt DC is the type of electrical current they use. AC (alternating current) switches direction periodically, while DC (direct current) flows in one direction. AC is typically used for household appliances and outlets, while DC is commonly used for electronic devices and vehicles.

4. Can a WIFI device be damaged if it is powered by the wrong voltage?

Yes, if a WIFI device is powered by a voltage that is too high or too low, it can potentially cause damage to the device. It is important to make sure that the device is compatible with the voltage it is being powered by.

5. How can I tell if a WIFI device is compatible with 12 volt DC?

Most WIFI devices will have a label or specification sheet that lists the acceptable voltage range. If the device does not specify a range, it is best to contact the manufacturer for clarification. Additionally, you can use a multimeter to test the voltage of the device's power source before connecting it to the WIFI device.
