Yes, if the device has a built in step down transformer. Think of it this way, the electricity in your household is a typical 230v. Mobile phones tend to use 6v of electricity. So when you plug your phone charger into the wall socket, 230v will run directly into that charger, through the cable and into your phone, typically blowing up the device or overloading it. That's why the charger has a transformer in it (a step-down transformer) which steps down the voltage from 230v to about 6-12v.
So hopefully that explains your question. If not, try to eleaborate a bit more so i can possible help further.
Thank you.

What is the difference between 12V 7AH Battery and 12V 12AH Battery?
Both are giving the data about storage capacity of a battery. For Ex. 12V 7AH Battery will run 7 hours if you are driving the load of 1Amp continuously. But 12 12AH Battery will run 12 hours if you are driving the load of 1Amp continuously.
How long will a 12v 2.5ah battery run a 3w LED?
12w at 12v = 1amp 3/12=0.25 0.25amp = 250ma 2.5ah= 2.5amps per hour 2.5/0.25=10 A 3w led at 12v 2.5ah battery will last 10 hours.
Can you run a 4.3v device with a 5v power adapter?
Yes, you can run a 4.3v device with a 5v power adapter as long as the amperage of the 4.3 volt device is under the amperage capacity of the 5 volt adapter.
Can a 220v window unit run off 208v?
Actually it can happen with a T.V but windows only takes 5v , not more and not less. A tv can take min 200 and max 220. So never give your windows more than 5v because it is an electronic device and TV is an electric device.
Can you use a 12V 300mA on a device that require 12V 1.0A?
You might be able to, but you probably *shouldn't*. 1 amp is equal to 1000 mA. The device requiring 1.0A is listing the maximum amount of amps that the device will need from it's power supply. If it only delivers 300 mA, there's a chance it may still run, but it could exceed the current needed to run the device (which could shorten it's life, or burn it out immediately in the worst case scenario). I currently am using a 12v 500mA supply with a light-based device requiring 12v 1A, and while it does work, the source device (an adapter) gets extremely hot and could be a fire hazard. Stick with the recommended matching specs, or if you can't match, even 12V2.0A would be safer and preferred.
Can a 12v 550ma device be run by a 12v 210ma supply?
No, the supplies output is too small. To run a 550mA device a supply source of 600mA and larger would be needed.
Can a computer case fan run off of a cars 12v dc line?
Yes, no problem.
What is the difference between 12V 12AH Battery and 12V 15AH Battery?
The AH means Amp Hours and is a measure of how much electricity the battery can store. Thus if the 12AH and 15AH batteries were connected to THE SAME device (one after the other) the 15AH battery would run the device for longer than the 12AH battery.
Will a 12v lithium battery rated at 1000ma run a 12v 100w light bulb?
no
Can you run a 12 volt vw beetle with a 6 volt generator?
No. The ignition needs 12v to run, the starter needs 12v to crank, the bulbs all need 12v to get bright enough...
How do you ground a inground pool light?
Most pool lights are 12v ac and run off a transformer so no need to ground
Is the device can locate if the gadget is off with GPS?
It depends on the device/gadget you're talking about. It would certainly be possible for a manufacturer to design a device where the GPS would always run even if the device itself was apparently off.
Does a corsa 2004 1.0 12v 3dr have a cambelt?
my 2000 model doesnearly all cars do, apart from the odd few that run off a chain
When connecting a stereo is the 12V contant wire a connection to the battery?
yes a 12v constant is a wire that has 12 volts even with the ignition off, you should not have to run a new wire the existing stereo should have one for station memory. with the ignition off test all wires on the stereo connector, only one should have power.
What is the difference between 12V 7AH Battery and 12V 12AH Battery?

How many 12V 50W bulbs can you run on a 20-60VA transformer?
A 60VA transformer can run only one 50W bulb.
How do you keep food cold on a camping trip?
Use a cool box with either dry ice packs or ice itself, also you can get 12v grudges that run off, mains a battery or a 12v socket in a car. Otherwise put everyting in a sealed bag and submerse it in water it'll keep cooler for longer
