FAQ

Will the  power inverter for your truck or car  drain your  battery?

Most Power Inverters for your Car or Truck will not drain your battery while you are driving you car. That’s because your car’s Alternator is doing the hard work of powering your Inverter.

Most Alternators are able to support upto a 1000 watts fairly easily. Your car or truck battery will have enough juice to run the Inverter for between 30 to 60 minutes before it needs recharging. 

A good plan is to get your engine running after 30 to 60 minutes so that the engine can recharge your battery. 

 
A Power Inverter for a Car or a Truck is an electronic device that uses the Car’s Battery as a power source for appliances in your vehicle.
 
The truck power inverter has AC output sockets which you can use to power a TV or Laptop or a Refrigerator or a Computer.
 
Depending on the amount of power the Inverter can produce, you could even run more power hogging appliances. 
 
How long can an auto battery run a 500-watt inverter?
 
It depends on your Car or Truck Battery. Auto Batteries are usually rated at 12 Volts. Look at the amp hour rating of the battery. Higher the amp hour rating the longer you will be able to run the inverter.
 
For example, if your battery is rated at a 100 amp hour, then its power capacity is 12 volt x 100 amp hour = 1200 watts.  Thus the Battery would be able to run the 500-watt Inverter for 1200 / 500 = 2.4 hours before it becomes completely drained.
 
In real life, you are able to achieve only about 80% of the rated capacity. SO the maximum time you could use the 500-watt power inverter for your truck or car for about 2 hours. 

What are Car and Truck Power Inverters?

Power Inverters for Cars and Power Inverters for Trucks are a special class of Power Inverters which are dedicated for in-vehicle use.

In the earlier sections, we talked about the USB and the cigarette lighter power outlets in your car or truck. These are sources of DC power. They work fine to charge phones, GPS etc.AIMS 3000 Power Inverter for Car

Power Inverters for Cars and Power Inverters for Trucks come in very handy when you want to use AC devices like your TV, or your Boom Box or a Power Tool or anything else that is plugged into the wall socket.

All Car Inverters and Truck Inverters work to convert the DC power coming from the car or truck battery into AC power.

Bingo, with your new Power Inverter you are ready to plug in any office or home electric device and start using your vehicle.

What devices can I run on my Car or Truck Power Inverter?

This discussion can get very technical with specifications of your car’s alternator, the current output at idle RPM speed for the car engine and more complications. So let me give you the short answer first.

Power Inverters for Cars or Power Inverters for Trucks that plugs into a Cigarette Lighter or 12 V Charging Outlet : If your power inverter plugs into the cigarette lighter outlet, then you can power devices which consume 10 amps or less.

So , we are talking Laptop, Television, Game Console etc. Just make sure that the device is rated at 120 watts or less.

Power Inverters for Cars or Power Inverters for Trucks that connect directly to the Battery :  These Power Inverters can power larger appliances like a Fridge, a Catalytic Heater, Cooking Equipment or Power Tools.

However, you have to be careful as many larger appliances need a lot of power to start up ( generally known as the starting watts)  and then settle down to using less power (Running Watts).

Irulu 3000 Power Inverter for Car

You should be fine if your appliances use 1500 or fewer watts of starting power and 1000 or fewer watts of running power.

For larger power inverters you need to make sure your battery and alternator are adequately powered. See the next section.

What numbers should I look at while sizing a Power Inverter?

It is best practice to make sure your Inverter has the rated power capability to run the appliances you plan to use.

Next, you need to make sure the Alternator in your vehicle can take the load.

If you are not careful you could run down your car battery or blow up the Alternator. The Alternator is the device in your car’s engine which keeps your batteries charged and topped up.

Finally, your car or truck battery should have enough capacity to take on the additional loads.

If you use the Power Inverter to power too many tools for example, the Alternator may not be able to keep up and you could end up with a discharged battery.

Power Inverter Load on your Car or Truck Alternator (What do the numbers mean?)

If you want to be absolutely certain that your car or truck alternator has the juice to support your inverter, you should look at the Alternators specs.

Your car or truck alternator has a rating specification which usually looks like this
50/120A 13.5V

What this is telling you is that your Alternator produces 50 amps of current when your engine is idling. Idling engines are usually operating at about 1500 RPM.  At that RPM your car’s alternator will produce about 50 Amps of current at 13.5 volts

The 120 Amp rating shows the maximum power generated by the alternator at a high engine RPM of 6000 or more.  Now, these figures are ideal figures and the real world outputs will differ.

Alternator Power Inverter

Thus, if your Alternator is producing about 6000 watts ( 50 amps x 12 volts) of power when it is idling. This is enough to power all the electrical systems of your car and you can safely siphon off about a 1000 watts to your devices through the Power Inverter.

If you have a higher rated  Alternator producing more output, then it’s possible to divert more power through the inverter to larger appliances.

If your Power Inverter is connected to the batteries via the fuse panel or directly, you have to be careful to ensure you don’t overload it and run down your batteries.

What Precautions must you take while using Power Inverters for Cars and Trucks?

Power Inverters for Cars and Trucks with higher power outputs which are normally directly connected to your car or truck batteries need to be handled with great care. There is a danger of sparking and fire when you overload the power inverter or have it operating in poorly ventilated spaces or exposed to water or the rain.

It’s super important not to overload the power inverter or the battery beyond their stated capacities.  Even with in-built safety fuses or dedicated circuits for the Power Inverter, it is vital to use additional external fuses to avoid a potentially hazardous situation.
