Can I use 13V for 12V?

A 13V power supply in this case will allow for voltage drop across long runs off cable. In this case, a 12V power supply might work fine. Dmc112 likes this.

Can I use 9V adapter for 12V?

It depends on whether your power supply is regulated. If you need regulated (stable) 12V, and the 9V supply is unregulated, it could give you up to 14V or slightly higher when not loaded. Chances are it will work, but we don’t know for sure.

Can you use any 12V adapter?

Voltage has to be an exact match. A 12V DC device needs a 12V DC adapter. If your device states it is 12V 3A, a 3A adapter can handle that load, but so can a 4A and 5A. The higher amperage (amp) power supply will not have to work as hard to handle a smaller load, and will run cooler and more stable.

What kind of 12 volt AC adapter do I Need?

. Belker 12W Universal 3V 4.5V 5V 6V 7.5V 9V 12V AC DC Adapter Power Supply for Household Electronics Router Speaker Smart Phone Tablet CCTV IP Camera – 1A 1000mA Amp Max. . Having an electronic adapter for your car parts is completely convenient and great for always having your devices charged and prepared.

Which is the correct voltage for an AC adapter?

It is important to use the correct volts when choosing the adapter as a device can only run on the rated voltage. The most common are 18V, 12V, 9V, 6V, 5V and 3V. Once you have confirmed the voltage of the device we need to find the amount of current that it uses. Current tells us how much power the device needs to operate.

Do you need a 110 volt to 220 volt adapter?

Buy a 110 volt to 220 volt adapter. While this may sound backward, remember that the wall voltage is 110 volts and your appliance needs 220 volts to run, so you need a device that will take 110 volts and step it up to 220 volts (in short, 110 mains to adapter to 220 device).

Can a DC adapter draw more than 12 volts?

If the tank only holds 10 gallons, it doesn’t matter that the underground reservoir holds 3000 gallons. Your car only needed 10, so it only took 10. Amperage works the same way. If the device is rated to draw 1A at 12 volts, it will try its hardest to pull 1A (and no more) at 12V.
