Plug a household socket into your car video



Hey guys, Cooley, like many of you who work from home.
But always think about contingency planning.
Whether in this pandemic or in a future event.
One of the things that come up is how you drive things in your car.
Maybe you have to be on the go, maybe you have to evacuate.
I'm not talking about things like phone, that's easy.
We know how to do it.
What if you want to put your laptop in your car and want to see it?
Regular household socket.
There you buy a so-called inverter.
This guy gives you household style sockets in your car.
Let's find out how to buy one and how to use it.
[MUSIC] This thing is called an inverter, but it doesn't really tell you much inverters.
What it does is the very different electricity in your car, which is typically 1

2 volts DC and converts it to a nominal 120 volts AC.
Now DC is basically making this a straight line if you want to imagine it that way.
AC does that.
You saw these sine waves.
And that means the polarity is reversed as it flows through the wiring.
Not only the voltage level, but also the voltage type is very different between DC in your car and AC that your laptop wants to see.
The inverter fixes this with a series of internal tricks.
Now there are no interesting moving parts in an inverter to show you how it works.
So I do it graphically and apologize in advance to you who are in the audience.
Here is household alternating current, it goes 120 volts in one direction.
Or polarity, then it reverses the polarity and makes 120 volts the other way?
It does the entire cycle you see there 60 times a second.
Let's compare it again with DC or DC compared to a baseline.
It is not about.
It doesn't change.
It doesn't even have a waveform.
Now the tension is different too.
In the car example, it's only 12 volts, but more than the voltage will notice the difference in the waveforms.
That is our big challenge.
What is the inverter doing to remedy this?
Imagine if you had a battery and had it in one direction, you would have turned it in the other direction and could do it very quickly with your hand.
Suppose you want to have created a very simple raw form of AC.
However, note that it is a square wave, not a sine wave.
The things you connect to household electrical outlets are designed to see a wave of signs.
They really want to see that, especially when it comes to sensitive electronics.
How do we make one look like the other?
Now if you go back to our battery analogy, if you take that battery in one direction on the left and pull increasing and then decreasing energy cans out of it, you will get something that looks very different from the square wave we're trying to get away from .
We have made some real progress.
If you take that and put it under our AC sine wave, you'll notice how it looks very similar.
We do the same with the battery and we have the other half of the alternating current.
This is at the heart of what an inverter does to convert direct current into a decent facsimile of alternating current and also to increase the voltage.
Okay, now we know what an inverter does and how it does it.
Let's find out how to buy one.
The first thing you want to do is look for one that really has a good quality sine wave converter and that does it well.
The equipment you connect to this thing will thank you for a high quality, faithful replica of a sine wave made of rectilinear direct current. Second, I like a good, heavy build quality in everything that generates or converts significant performance that they do.
It has a good weight.
It is a name brand.
It has a nice, heavy cable that connects it to the car.
All of this gives me confidence.
It also has security systems, a backing in case it gets overloaded.
And a circuit breaker is triggered in here, which temporarily goes out in the event of overheating. You can find recycling instructions here on the device itself.
If it overheats and you want to bring it back.
Another thing to look for, I think my third point is your expense.
This is the biggest question you will be asking yourself: how much watts will this thing support that is out here?
This 1375 watts.
It should be a simple specification to look at one of those D rates that assume you have 80% of it, not 100% of it just to be sure, and protection is probably built in, and then you see This laptop charger records how much your things are.
It's almost impossible to read, but it's 65 watts.
So that takes part of my 375.
Then add what else you will add there.
Maybe you charge two laptops.
You are now up to 130 years old. Maybe charge a few drone batteries while you're on your way to a drone shoot. One of these chargers fell.
Add all this up again and again, keep a pillow and then you'll be in good shape.
But the last thing is if you use one of them almost constantly, regularly and especially a large one that pulls more than that. You may want to have it integrated into your car's electrical system.
In other words, you have a self-routing cable that goes to the battery, not this thing that essentially flows into a cigarette lighter, as we used to call it a 12 volt socket.
These things are not really meant for constant high current transmission.
A hardline to your battery would be better.
Bonus points: If a high-performance generator system is available in your car, the battery will be charged better if the inverter discharges it.
