Power inverters are a great devices to used to your electrical gadgets especially
in time of emergency such as when power outage occur at your home, when you are on your vehicle, and when you are on a camping trip. Inverters can convert the energy from your battery (Direct Current Energy) into an Alternating Current energy that can be used to power electronic devices. A 12v inverter can be very useful when you are on a camping trip or when you want to use your electronic devices in the car.
You can directly plug the adapter of your 12v power inverter into your car cigarette lighter socket located on the dashboard. You can now plug your electronic devices to this inverter that will output a AC energy that it needs. The devices that you can only use on this type of inverter are those devices that only uses 100 watts of power or less. It can power small devices like cellphones and laptops.
There are many things you want to look at when you are buying a 12v power inverter. I don't recommend that you purchase the cheap one because they can easily fail and leave you in a bad situation when you relying to it. Sometimes these cheap inverters can even damage your electronic devices that it connected to it. When you are buying a power inverter make sure that it has a fail-safe or a fuse. The fail-safe or fuse that will blow if the voltage becomes too high. When the fuse blew it will protect the complex circuit of the device. Also make sure that the fuse of the inverter is easy to replace. Another thing a good inverter also have a built in fan to keep it cool and prevent failure due to heat. Also make sure that the no load draw is very low. It means that when there is no load connected to the power inverters it will not draw much power. There are also some inverter have a zero no load draw.
There are also important features that the 12v power inverter have:
Good 12 volt inverter have a polarity fail safe
Good 12 volt inverter will be efficient
Good 12 volt inverters will have a high voltage overload fail safe
Good 12 volt inverter will have a low voltage alarm
Good 12 volt inverters will have a low voltage shutdown
Good 12 volt inverter will have a high surge capacity
Good 12 volt inverters will have a decent warranty
Now that you know all the things you want to know about a 12 volt power inverter. You will be not failing purchasing the low quality inverters on the market. Now if you don't care about the quality and you still want to purchase the cheaper one. Buy one from your local stores but if it fails you don't say i didn't tell you so.
