Hi I Wonder if you can tell me witch one I need if I'm going to plug my portable air compressor
@@marcosm102 Is you air compressor powered via AC (110/120V) or DC (like the cigarette lighter socket in your vehicle)?
If i has an AC (wall plug), let me know what the air compressor draws (should have a label on it that says the Amps (A) or Watts (W) that it needs)..
@@WaganTech hi , yes it says 2.4 Amp, 90 w .
And it's a twin stack portable air compressor 120 v
@@marcosm102 2.4A @120V is 288W (watts).
A 400W inverter would be more than enough as long as it doesn't have an inrush (surge) current that it draws on startup.
What is the model and brand of the compressor?
@@WaganTech that's great , it is a kobalt. Model 3320447
Hi Friendly Electrician here, it's important to note that when looking at chargers for devices such as laptops or in my case power tools, you should check the charger's AC input rather than it's DC output. While the charger may say 60w, it could require 120v and 1.5A AC as an input. Meaning it consumed 180w from the wall outlet or the inverter.
Yes, you're 100% correct. Thanks for adding that comment!
Man Justin is so smart and is incredibly hansom. I feel like I can trust whatever he tells me about power inverters. Thanks for the video.
I think its that scruffy grey beard that just screams trust... like your favorite teddy bear!
I don’t think I’ve ever learned so much in a five minute video 🤣thank you so much for all your help! I’m headed to Best Buy to buy one right now
I appreciate your comment, thanks!! ♥
Thanks for making it so,so easy to understand, I'll be checking you guys for my inverter 👍
You should be a teacher. This video is great. Thank you!!!
Thank you Mike, I appreciate that!
Thank you ! Such clear explanation even a beginner can understand.

Thanks for explaining most of the basic things about inverters.......
Glad it was helpful! We try to help others out there as much as we can!
Ok the Dive into the video got me hooked! 🤣 My uncle gave me one of these things and didn’t know what to do with it. I like to travel in my truck a lot. Thanks fir the information.👍🏽
My pleasure! Let me know if you have any Q's and thanks for watching!
great help and thank you for sharing. this is the most important when it comes to understanding power.
Thank you Roy!
the burden of the knowledge of Inverters has been lifted off....thank you for doing this!
Our pleasure!
I was thinking of installing a hard wired inverter with the purpose of running an electric pressure washe and and a carpet shampooer. This video really helped me, thank y'all!
Awesome, thanks for the feedback!
VERY informative, Thank you!
Thanks for watching!
This was such a helpful video. I am still a little concerned about the peak surge of my power tools but now I at least have a basic knowledge of what's going on. Thank you so much!
Cody, I'd be more than happy to help you figure out your set up! Shoot us an email if you have any Q's customerservice(at)wagan.com
Very good info ,thank you very much ..I knew a bit ..but this vid covers the simple math and has really helped me to decide to go over the top and probably go with 4000w ..so I have a good range of scope ..even on peak low power (60 w) it should cover it
Thank you very much for your comment and for watching the video; I am glad it was helpful to you.
If you have any other Q's, certainly let us know!
It's a very helpful video! Thanks a lot!

Very well explained. Thanks. I've been planning to get a hardwired inverter so I can recharge my drone and camera and also use my laptop to edit while off the grid at random locations huddled in a tent. So far I've just been hearing some jargon from people I ask about this and have procrastinated.
Halldor, it's very easy to procrastinate on projects like this. It sounds like all you need is a small inverter to power your drone and laptop. You may be able to get away with one that simply plugs into the cigarette lighter socket inside your car as these can provide around 180W-240W (depending on your vehicle's fuse).
thank you for sharing! i love to watch van life videos and i always wondered what do they mean by inverter
Glad I could help and thanks for watching! Let me know if you ever need help installing or selecting one for your use!

First time viewer here. Thank you! Next: I'll be watching more of your videos to determine what type of inverter is right for me in terms of wattage. I have a Toyota Prius and intend to do some car camping soon. I'll primarily be using the inverter to connect cooking appliances, nothing major, mainly my rice cooker and hot water kettle. What I haven't figured out is...must the vehicle be powered on and running for the duration of the use of the appliance(s) ? I'm guessing the answer is "yes." Can someone please clarify? I've purchased a self-charging jump starter power bank to protect myself against battery drainage just in case...
EVs definitely make the equation a lot harder. If you are able to directly connect the inverter to the battery, then the car will not have to be on.
You will have to find out if a direct connection is possible as the batteries are lithium ion and probably produce a higher voltage than what a lot of inverters are capable of accepting as input.
All it takes is a battery management system to regulate the output power to an acceptable level for the inverter... This may already be done for you so you'll want to check with Toyota.
As for which inverter you need, take a look at the amperage or wattage requirement of the hot water kettle and rice cooker. If you're going to be running those appliances concurrently, you'll need to add that amperage or wattage requirement together.
Add an additional 20% to that number and you'll have the size of inverter that you'll need!
Gotta get that pure sine wave 🌊
It's the one I prefer too!
Thanks I have one and its working
AWESOME! Thanks for sharing!
These things saved my life as a project car owner without a garage. I could just drive my car out to the middle of nowhere and use my power tools on my car.
That's awesome, thanks for sharing!
Jeez, thanks.. I now know the reason why my modified sine wave inverter burn and create a white smoke... 😅
I just used an electricfan..
Be careful with inverters out there. Good modified sine inverters should not burn like that.
Thanks.
Thanks for watching!
Awesome video bro 😎
Thank you, I appreciate it!!
Man you're beautiful..!! And I'm not talking about your likeness or your voice... It's your knowledge my good Sir... Thank you for your help...!! Learned a lot...!!
I'm happy that I could help! Thank you for the kind words!
Thank you. Im a musician busker i carry my electric drums amplifier & my foot pedals around with me &. I am definitely buying 1 the pure one. Thanks 🤗🎸🎶🎤🥁🎹📱
Thanks 🙏
Thank you for watching Salem!
Hi!! So to run a small fridge and/or a coffee machine, which sine would I need :). Great vid- super helpful
Thanks for your positive feedback, I appreciate it! For either of those appliances, you could use a Modified Sine Wave. Appliances like the coffee maker (or anything with a heating coil: personal heater, hair dryer, etc.) will make a noticeable "humming noise" when using a MSW Inverter.
Very informative
Thanks for your comment and for watching !!!
@@WaganTech keep on update and educating ...🙏🙏👍
@@meaww7373 We will! Thanks for watching!
One thing I would like to add is, with a 12 volt system in a vehicle you want to run a household appliance on, get the amperage rating the appliance draws.
While inverters are NEVER 100% efficient, it is a general rule of thumb whatever the appliance wants will be ten times that from the battery.
(Think going from 12 to 120 volts, of course it would be).
Mikiness, I get what you're saying and I agree that no inverter will ever be 100% efficient. Going from 12V to 120V is not a linear scale and won't draw the power from the battery in the same manner.
bro. So you're part Asian. Elaborate on that. Besides that, the way you dropped the knowledge, %100 useful and fully explains wattage and amps in a way that makes sense to anyone dealing with it. This video will be shared to more people than you intended.
Very informative. Thankyou. Would I be able to run a 300w PA system from one of these?
Indeed you can as long as you get the appropriate size inverter to handle it. A 400W+ Inverter would handle it with ease - I recommend our Elite 400W Pro or the newer Pure Line 400.
Thanks
Atlen, my pleasure! Thanks for watching ♥!
Great video. Do I have to car keep running while I’m using the inverter? Thank You
Thank you and good question!
You don't necessarily have to keep the engine running; it is dependent on a lot of factors including battery size, load, etc.
In an average car, you don't need to keep the engine running for charging a laptop or other small electronics.
If you're running a blender for just a few seconds, you wont have the engine running.
If you plan on running a high-wattage item for a long period of time or a low-wattage item for a long time, then you'll need to run the engine a bit.
Thanks for your help. I'm trying to decide if I should get an inverter instead of a solar generator. I really just want power accessible incase the power goes out but sounds like the inverter needs a car so not good at home, correct?
Our Lithium Cubes are a great alternative if the car isn't nearby. With a Solar panel, they are a true solar generator too!
ua-cam.com/users/results?search_query=lithium+cube
Thanks , very well information.. my question.. is a good for track and how many watts needed for track thanks..
What do you mean "is it good for track"? What is track?
Respect 🇯🇲
I have some questions. I've been watching various bus conversion videos. I've noticed that lots of builds utilize inverters. I watched several people cut a switch on/off to a light switch, mini split AC, refrigerator and mention the inverter, what exactly are they doing? Also, I will be doing a conversion build of my own in the future and would like to know about the purpose of the batteries pertaining to solar and the inverters... how do they coincide? Can you please explain or direct me to a source of information? I am a visual and kinesthetic learner. Thanks for any advice/suggestions that you give.
Hi Cee Cee, I would love to be a part of your build knowledge! I am not sure what your first question is referring to- can you show an example? In regard to your second question, usually people will have a dedicated battery bank that powers their needs while the vehicle isn't running (when it is running, the batteries will be charged from the vehicle's alternator). The solar panel has a solar charge controller that is placed in-line between the panel and batteries to regulate the electrical current flow from the panel. Our inverter is down-stream of that and draws power from said battery bank to provide power to your electronic devices.
Thanks for the great info! I have a question though. If i have one hardwired into van, and i use a jump starter with 1000A peak power, would i have to disconnect the inverter?
Arnie, thanks for the comment - I appreciate it!
If the Inverter is wired as it should be (downstream of the battery), there should be no reason that it would be affected by jump-starting a vehicle.
I would urge you to turn off the inverter and anything that draws power (radio, lights, etc.) prior to jumpstarting a vehicle.
Thanks for the explanation. One question how do I calculate how long can I run a 500 watts laptop with 1000 watts inverter?
You can conceivably run a 500W laptop forever as long as the battery (power source) will supply the power. If you know the battery size that you have, I can tell you how long it will sustain a 500w load with a 1000w inverter - shoot me an email at customerservice@wagan.com ... and thanks for watching!
Great video, if i have a 500 watt inverter and im only using 100 watts, will my inverter constantly draw 500 watts from the battery or only what is being used?
The inverter will only draw the power it needs to make the conversion. In your example, the inverter will only be pulling the 100 watts needed!
Thank you! That was to the point!
Glad it helped!
Hi there.. great video.. would like to ask if for an equipment like a 1200W vacuum cleaner and larger sized motorized equipment.. is 20% buffer still applicable? Tnx..
Hi Christian,
Yes the buffer is applicable, even more so with larger appliances! I would certainly recommend the 20% buffer on higher wattage appliances.
I feel like if power goes off at your house, you would use generators for big appliances and other circuits. I would use power inverters for only small applications such as phone and laptops correct? By the way, it was a fun video:)
For the average person in suburbia, you are correct. This is (in relation to people living in houses) geared more for those with solar panels or off-grid cabin needs.
If you already have the solar panels mounted to your roof, then a battery back-up system is way more discreet, requires no "fuel", produces no fumes, and is quieter than a generator.
If were talking strictly power outages, then a generator is probably the better bet.

How will I find out "Peak Surge" 😲😲😲
I have a bank of 20 Li-lion 3.7v 5000mAh rechargeable batteries I want to run certain appliances, either altogether or one or two at a time.
1) Desktop 500w psu no more 8 hours
2) Microwave 900w twice a day no more than 10 minutes
3) Panasonic TV 31w no more than 6 hours
4) Sky Set-top box 30w standby daily
5) Fridge - Freezer 195kWh pa = 22w per day ( I think )
6) Kettle periodically 1500w
UK Voltage 220v 50Hertz
I have tried working out the wattage but failed miserably.🤐🤐🤐
So what size PURE SINE WAVE inverter do you think I will need🤔🤔🤔
tell me how to use them in a hurricane situation in FL. can they run a fridge? how big, how long? I was told to turn on fridge for 1 HR for 4 hrs of rest
Diego, that's a very good question! Ideally you'll want to have a car nearby to power the inverter when needed.
If it's a newer style refrigerator, they generally run in the range of 250 to 400 watts, you'll want to check the specs of the refrigerator to see what its running wattage is. When you're concerned with power, you'll want to open the refrigerator as little as possible to keep the cold inside.
Refrigerators only run as needed, so they're actually quite power efficient in that sense.
Great videos, I have a Mackie Thump 15 loudspeaker 1000 W, which inverter would you recommend on your website
For speakers, I always recommend Pure Sine to avoid any humming noise that may be generated! If your speaker is drawing 1000W, I would recommend getting a PSW inverter that is 1200W or larger like our Pure Line 2000.
I’ll be going camping this summer 🏕️ my question is will a Milwaukee 18 volt 175 watt inverter power up my cpap machine ??
That should work fine since most CPAP machines will only require 75w. But, check with Milwaukee for details.
This video was very instructive when it came to inverters, but either I missed it or he didn't mention how much power could be stored in a battery connected to the inverter.
The amount of battery power stored depends on the battery size, chemistry and other factors. You can essentially use any size battery/bank to power the inverter as long as the battery voltage matches the inverter's capability.
You could have a massive battery bank of 5000AH + with no issues.
Hi Justin what type of temporary portable battery source is best for running a small microwave or refrigerator in a van? Thanks
Hi! Microwaves draw a huge amount of power (like around 1100 watts), a small dorm fridge will only draw about 70 watts. You'll need an inverter that can handle that load as-well-as a battery that can feed that power (for the microwave). I can help you select the right size battery if that helps?! I just need to know the expected run-times between charges (or driving).
Can this be hooked up straight to a battery that’s not under the vehicles hood? You have videos on this?
Yes, you can connect straight to any battery that is the appropriate voltage. You should always fuse the cable between the battery and inverter.
We have an excellent blog here: wagan.com/blogs/news/how-to-connect-a-large-or-small-inverter-to-a-battery
Hi... I wondering is is this inverter can save charges just like powerbank??? Im planning getting one for oxygen concentrator just in case there's eletric blackout....
Hi there!
No, power inverters only convert DC into AC current. You have to connect a battery to them.
You would need a portable power supply like our Lithium Cube - this has an onboard lithium ion battery with AC, DC, and USB power ports.
wagan.com/collections/lithium-cubes
Do we need something between the inverter and battery to keep from draining the battery, to tell us if we need to recharge the battery? Thanks!
You don't need to add anything else to the system except a fuse when using our inverters as they have a low-battery alarm (around 10.5V) and an automatic off feature (at around 9.5V) to help keep your battery from over-discharging and becoming irreparably damaged.
Great advice. One dumb question. my camper van has a 800w inverter which is overkill for what I want to use it for. My laptop only requires 12 w. Can I still plug in my laptop to my inverter safely or will this blow it out? I don't think it will harm it if it is a sinewave but I just want to make sue.
Bron, it is hard to say without seeing your laptop set-up. Most laptops require 19V to charge - a 12V to 19V step-up (or "up-converter") charger can be a solution to your needs IF your laptop meets those requirements.
Can I charge the inverter from a regular wall outlet ? Or just only can work with cigarette outlet ?
Hi! Inverters don't have batteries, so they can't be charged. The power inverter is primarily to take your car's DC power and turn it into useable AC power (regular wall outlet).
If you buy a portable power pack that has a battery and an inverter built in, those can be charged from a wall outlet, car socket, even solar power: wagan.com/collections/lithium-cubes
Could I mount it somewhere like the passenger footwell and leave it hardwired the whole time?
Yes! As long as it gets airflow it's not a problem.
If I do reverse connection from inverter input 240 volts output 26 volts , using solar with 12 volts battery to get 240 volts out from input will it be possible.
I'm sorry, I don't understand your question.
Inverters cannot supply DC voltage and you can't supply it AC voltage. Inverters can only input DC voltage to output AC voltage.
Hope this helps!
I've gone down the rabbit hole of dual battery power systems for camping. If I have a coffee machine that is 15 amps x 120 volts does that require an inverter of 1800 or greater?
Jim, yes you have it correct!
I would recommend an inverter of 2000W as we suggest a buffer of +15% over what's needed.
🙏
Do you jave to keep engine running while using power inverter? What does DC-DC in car charger do with inverter? Thanks
Depending on the load and the run-time, you may or may not have to keep the engine running.
For instance, if you're powering a laptop off of the inverter, then you'll likely get several hours before needing to run the engine (which will recharge the vehicle's battery).
On the other hand, if you're running a microwave/hairdryer/blender or other high-wattage device for an extended amount of time, then you'll definitely want to have the engine running.
A DC to DC charger simply monitors and regulates the power going to a battery to ensure it charges correctly. They can be used alongside most inverters with no issue.
I wanted to buy since I usually don’t have light but how long will the b3 last and how do I get the battery charged
Remember that inverters only convert the power from DC to AC and doesn't have any battery storage. You would have to rely on the battery source you're powering from. If you want an easy solution, you can use Wagan Tech's Lithium Cubes: wagan.com/collections/lithium-cubes
Do you have any videos that show the waveforms of these inverters under load?
We currently do not have any videos on their waveforms, but it sounds like something we should do! Check back soon!
Due to the over 100 heat weather in Ca, We lost power twice in a week. Do you think is safe to run a home refrigerator using a 2000 watt car power inverter?
You can as long as the battery can handle the load. We're in CA too, today is going to be a scorcher - stay cool!
What watt inverter do u recommend for a 750 w microwave for semi? I had a 1500 watt and it will turn on 3 seconds n beep n shut off.
Joey, we have tested many microwaves sold by 18 wheeler supply companies and have found that some microwaves do not like modified sine wave inverters.
I suspect that you're inverter is a modified sine wave inverter.
Also double check to be sure that your microwave is only pulling 750 Watts; that inverter is double the stated microwave wattage requirement, so it should have been good - wattage wise.
Dope
Would a Bestek 300 watt inverter be good for my Milwaukee M-18 super charger?
what are the input specs for the charger?
Great video! I have a question tho. I am looking to buy devices for my families homes in case of a power outage. I've been looking at portable power stations, but then I saw power inverters which seem to power up higher wattages than the stations, yet they are cheaper than power stations. Why is this? And which device is best for a power outage, inverters or stations? Thank you!
Quiana, great question!
Power Inverters convert DC (like your car's battery) power into AC power (your home wall outlet). They are great for powering small appliances and everything else including your entire house. Like anything requiring power, the limitation is the battery (or battery bank) that is supplying the power. For powering devices/appliances close to a battery power supply (like your car), inverters are ideal.
On the other hand you have devices like our Lithium Cubes. They have a built-in power inverter (and of course: USB, DC, etc.) and are great for activities away from the car or situations where you don't want to deplete your car's battery (like camping). Their limitation is the internal battery; a trade-off for ease of use and portability.
Like anything, it depends on your needs and use-case. You are looking for something to supply power in case of emergency at home. Our Lithium Cube 1200 is perfect for that as long as you don't need to run a lot of big appliances (refrigerator, air Conditioning, microwave, etc.). If you need to power those items, an Inverter with a large battery bank is ideal. If you just need to power lights, a tv, fan, recharge your phone, etc., the Lithium Cubes are perfect!
@@WaganTech Okay understood. Thank you so much for clarifying that for me!
@@quianadumas3550 it's my pleasure! If you have any more Q's, feel free to ask!
Please PLEASE 🙏🙏 answer my question as I need to make a decision asap. what is the BEST INVERTER for a home refrigerator and fan? also how many batteries would I need?
Contact our customer service with the amperage (or wattage) draw of both devices and how long you intend to run them (hours). Customerservice@Wagan.com
you explained the difference between Pure sine and Modified sine, but in my mind i would just then want to go with Pure sine as it can be used for all? Is there a negative reason for using pure sine on a blender for example?
No, there's never a negative to using pure sine over modified sine. The only reason that MSW exists is price point.
Question, with this type of invertor does the car or vehicle have to be running in order to use the invertor?
The answer is dependent on the load and the size of the car's battery. If you're powering a laptop in an SUV, then the engine need not be running. If you're using a microwave in the same SUV, then yes you should have the engine running.
When running high-wattage appliances, or if powering from a smaller battery, you should keep the engine running.
If you give me your vehicle type and load-requirements, I can better answer this for you.
If hooked up to my trucks battery, should I turn on the engine before using the inverter?
If it is possible, then yes. While a surge won't hurt the inverter, it is best to start the engine prior to using appliances.
Got a primordial question please, do you need a battery to use the inverter ? Or can the inverter itself be charged with electricity
And second question, if you need a battery to use it, how do you charge the battery ?
David,
Yes, you will need a battery to use with the inverter as it does not have a way to power itself.
There are several ways to charge the battery:
You can use a standard automotive battery charger, you can use a solar panel, or you may opt to charge it using your vehicle's alternator (the very same way that your vehicle charges its starting battery.
Take a look at my blog here: wagan.com/blogs/news/what-is-a-power-inverter-more
I’m mad that corny dive *MADE ME LAUGH & want to watch even more.* 🤣🤣🤣
which battery to match which invertor, does it matter?
Hi there!
In selecting a battery for use with your inverter, make sure that the inverter is compatible with the battery chemistry. Almost all inverters are made to work with standard automotive batteries: (SLA, AGM, Maintenance Free, Flooded, Wet Cell, VRLA, Gel, Lead-Acid, Vented, Deep Cycle, etc.). The only issue would be if you're trying to use a lithium-ion battery.
Battery size matters (Ah rating/Capacity) when you're trying to run appliances for an extended amount of time.
If you need more info on this, shoot me an email at customerservice@wagan.com and we can figure out what your requirements are.
Thank you for the video. Doe this mean when I have a 4000 watts inverter, I may connect and run a 3000 watts vacuum cleaner?
First off, thanks for your Q and for watching!
If it is one of our inverters that you own, then the answer is YES!
@@WaganTech certainly your product here in South Africa 🇿🇦. Should I start each motor gradually to run full 3000 watts on the 4000 watts pure sinewave inverter.
I am learning how this works as I just started a pressure washing business with intentions of adding gutter cleaning using a vacuum cleaner with a 12v batter 100ah and a 4000 watts inverter.
whats the minimum 12v battery amps i can run an inverter on?.....
It is all dependent on the item that you plan to power with it... the larger the item or the longer run-time, the larger the battery you'll need.
If you send me an email with your appliance wattage/amperage and your required run-time, I can tell you what minimum size battery you will need to run it.
customerservice@wagan.com
Are we talking about input or output in order to calculate watts?
Usually you calculate output watts to determine your power draw your device(s) needs. If you don't have the watts, you can calculate it simply by Amps * Volts = Watts. Hope that helps!
So if I run one in my semi, use a microwave on it
How often can I use it? Does it matter if vehicle is running or not? And if not how much can I use it before I have to recharge?
Alan,
Being that you're using this in a semi, that means that you already have two batteries which gives you more power options.
"How often can I use it?"
You can use it whenever you like. Your only limit is the power supply (batteries/alternator).
"Does it matter if vehicle is running or not?"
For short use, no. If you're going to be running the microwave for more than a minute or so, then I would have the engine running.
"how much can I use it before I have to recharge?" This is dependent on your battery size and how many watts you're pulling. If you come up with those figures, I can give you an accurate answer.
Good evening sir. Please i just watched yr video now. It was really helpful. But please i also have a question can a blender of 220v work in a place where the voltage is 110v?
Lydia, the only way to use a 220v appliance on a 110v outlet is to use a voltage converter. A power inverter can only convert DC voltage (like from a car battery) into AC voltage (like your blender).
Thank you so much sir. And God bless you sir
@@lydianyarkoh363 My pleasure! Feel free to reach out if you have any more questions!
what happens if you use a much bigger inverter than you need.? ie:- 1500 watt and my appliances are 800 watts maximum
Good Question! There are no detriments to using an inverter that is too large.... the only thing that will suffer is efficiency as inverters should be outputting around 80%+ of its capacity to be the most efficient. At 800W , a 1500W inverter would be running at 53%+ efficiency which would be just fine.
