Did You Know?


Some vehicles already have an inverter built in that you can plug your laptop into, but its only 100 watts, not enough to power things like your home gas furnace. Some new vehicles have larger inverters built in like Ford F150 ProPower 2000watt which idles the engine 85 hours on a tank, or the 2021 Toyota Highlander Hybrid and also the Sienna minivan has a 1500 watt inverter built in. FORD wants you to buy a new $80,000 truck with a built in 2000 watt inverter generator. CarGenerator lets you use the vehicle you already own, and create a good power solution for 1% of that cost, starting at just $795.

Next time your home power goes out, these are the traditional ways to get backup power


Pros: instant switchover within seconds, all lights appliances etc run, unlimited runtime if connected to your gas line supply.

Cons: Yearly maint fee between $300 $400, high cost of initial install $10k plus permitting, construction running gas lines etc


Pros: Silent, no fumes, easy storage, eco friendly.

Cons: limited capacity. Whether it’s a battery jumper pack or a Tesla Powerwall, once you start using power, watch your battery meter constantly drop and eventually you run out of power.


Pros: quick and easy to buy from any local hardware store home depot, can power many items in your house

Cons: reliability is a major issue. Unless you maintain these perfectly and test and use them regularly, they may not start when you most need. Also storing large cans of gas in your garage or garden shed is a fire and explosion hazard, and they need to be stabilized for long term storage and kept fresh. Noisy and Smelly also...

You can keep your whole house warm for 50-70 hours powering your gas furnace, oil boiler, or run your fridge and internet or TV – using the car right there in your driveway. Safely and easily, without the hassles of maintaining a gas generator and hoping it will start when you need it most, and storing dangerous gas cans etc. WHATS THE UPSIDE? ultralight 11 pounds, very reliable if your vehicle starts you have power, quiet, clean, eco friendly less emissions than portable gas generators, works with gas/diesel/pure electric and hybrids. Powers home essentials only like furnace, fridge, freezer. Runtime 50-70 hours on a typical vehicle gas tank. WHATS THE DOWNSIDE? cannot power everything in your house all at once, and cannot power large loads like Air Conditioning, electric furnace, stove, hot tub, etc. If your power goes out several times per month or you need to power large items in your house like hot tubs, washer/dryer, etc then CarGenerator is not for you, your only option is a regular traditional gas generator.

Why Your Vehicle Is Better For Backup Power, Instead Of A Traditional Gas Generator?

Lightweight and Convenient

Starting at just 9 pounds, this tiny device hooks up in a minute, and powers your home for days.

Longer Runtime

You get 50-70 hours of runtime from your car gas tank, versus refilling a small gas generator tank every 4-6 hours.

Environmentally Superior

Gas generators are known to be loud and smelly for a reason, they have almost no emissions control or filters.

Electric / Hybrid cars

Electric / Hybrid cars work great with CarGenerator, and in the case of a pure electric vehicle you use no gasoline at all.

Less Gas

Surprise! Running a compact sedan at idle uses less gasoline than running a generator. Honda 1000watt generator .19 gal/hr, compact sedan 2 litre engine .16 gal/hr Source:

Ultra-Reliable & Hassle Free

Ready when you need it. If your car starts you have power. Hassle Free no maintenance or oil changes, ever.


Today I’m going to share a secret with you about how you can get backup power for your house to keep your family safe and warm for days, during your next blackout. Up till now this knowledge has been the exclusive secret domain of “techies” and car mechanic Youtube DIY types. What’s the secret you ask? An Inverter. This device converts the 12volt power from your vehicle, into 110/120 volt standard household AC power. You can use this to run your home gas furnace, fridge, sump pump, lights, computers and internet or TV.


You can buy our DIY smart inverter only for $295

Our DRY USE ONLY CarGenerator model is $460 this is great for a sunny day or good weather situations.

Our flagship ALLWEATHER MODEL is $795. This is a turn-key solution, fully weatherproof, you can use in any kind of storm, rain, snow, ice, with custom heatproof integrated cables. It actually costs even less if you think about it, $615 plus $180 of bonus accessories = $795. This includes our $180 bonus package of furnace plug kit, AC power watt meter, 3 year extended warranty, and free shipping.


IDLING CARS AND OLD WIVES TALES One of the most common objections, is it bad to idle your vehicle for an extended time? Sorry nope, that’s an old wives’ tale... in fact millions of vehicles idle every day, not only police cars, taxis, etc but also regular ordinary folks waiting to pickup the kids from soccer, waiting at the airport, stuck in traffic and more. For the 10-20 hours per year you might need to use your vehicle as a generator, is not even a drop in the bucket to the hundreds of hours you already idle every year. Prove it to yourself... get a vehicle scanner and run it on your own personal vehicle, and see how many "idle hours" are already on the engine clock. Even sitting at a stop light you will notice your idle hours are ticking up.

Frequently Asked Questions

Do I need to leave my car engine running?

Unless you own a wind farm or a giant solar array, when the power goes out, there are only two ways of generating backup power; 1) Producing power from backup batteries, which will only last a few hours at best, or 2) producing power from an internal combustion engine. Like a traditional gas generator, with CarGenerator, a gas motor provides the power, turning fuel into electricity. Where CarGenerator is different is that it has a much larger gas tank, so 50-70 hours of runtime is possible instead of 5-8, and it’s only 16 pounds, because you are using your car’s engine instead of one that’s permanently coupled to a generator. Thanks to the superior emissions control systems of modern vehicle, CarGenerator is actually more environmentally-friendly as well.

Will I run out of gas?

A typical vehicle can provide power for 50+ hours up to 80+ hours on a tank. Compare this to a typical portable gas generator that needs attention every 4-5 hours because of its tiny little gas tank.

Will it drain my battery?

Nope. Not even one tiny bit… Once your motor is running, your battery isn’t even necessary in the equation (true fact, ask your mechanic). Power for the car’s electrical system (or your house or RV) actually comes from the alternator. Batteries are there just to start the car and get the motor running, so your battery won’t even notice CarGenerator being attached.


Nope, not unless you were planning on hooking up CarGenerator to a ’59 Studebaker. Modern cars are designed to handle all kinds of operating conditions, and at idle, the car’s computer makes sure its engine is adequately cooled and lubricated. Police vehicles and ambulances are typically idled all the time, and usually enter their second service lives at 100,000+ miles. If you need CarGenerator more than a handful of times per year, you’d likely be better off with a natural-gas-powered, hard-wired permanent generator at a cost of $5,000+ dollars. For everyone else, rest assured that your car is operating well within its design limits.


Nope. Not a chance…. Once you start your engine, just lock your doors with a spare key (see our instruction manual), and depending on your location you can put a steering wheel lock on for additional protection (about $12 at Wal-Mart) which makes it almost impossible to steal the vehicle. If you’re still worried, or you live in a neighborhood with a lot of chalk outlines on the sidewalk, CarGenerator can supply you with a wheel boot, to make theft impossible without a trailer or an angle grinder. If a thief brings a trailer to steal your car, it won’t matter if the key is in it or not. If they bring an angle grinder, you will definitely hear them, and should probably call the police. In any event you would know immediately because your power would go out!

Why not just buy a regular gas generator?

Three words: Reliable. Ultralight. Run-time.

RELIABLE – the #1 problem with traditional generators? F.T.S. – fail to start. When you need it most they don’t start up because of old gas or no maintenance. If your car starts, you have power.

ULTRALIGHT – CarGenerator is just 16 pounds, versus typical generators that are 60 – 160 pound beasts.

RUN-TIME – CarGenerator has a run-time of 50-80+ hours, where typical generators need to be refilled every 4-5 hours.

What about the environment?

Its actually more environmentally friendly because typical vehicles already have thousands of dollars worth of emissions controls systems in place; computers, oxygen sensors, and catalytic converters. In some cities, a ULEV (like a Toyota Prius) actually puts out less pollution than there is in the ambient air! Gross, right? A standard generator is basically a glorified lawn mower, with no emissions equipment at all!

Why not just get a cheap inverter then?

Totally an option. If you want to jerry-rig an inverter in a waterproof container, you certainly could, but if you want to plug in any sensitive electronics (like your furnace, laptop, or medical device) you’ll need pure-sine wave power to avoid damage and ensure good performance. A 1000 watt, pure sine wave inverter can be purchased from Walmart for about $400. Then you need a set of heat-proof booster cables for prolonged use under the hood (about $100), and finally, you need a weather-proof housing that also allows for ventilation. If you’re an industrious, DIY-er who loves saving money above all else, you could definitely build your own CarGenerator; you’ll save about $150, providing your time isn’t worth anything. For the rest of us, who value our time and want an easy, proven solution, CarGenerator is simply the best possible option for worry-free, temporary power.

Is up to 1000 watts enough?

1000 watts is not a lot, however consider the following:

- To run your gas or oil furnace and heat your entire house, only requires between 200-300 watts on average.

- To run a fridge only requires 200-300 watts typically

- The number one identified problem with gas generator is….? F.T.S. = Fail to start. CarGenerator is always ready.

- Keeping a good supply of gas cans stored, and keeping them all fresh every few months, is a nuisance and a fire safety hazard.

- If you need lots of backup power for all your house appliances and big draw items like a hot tub, wine cellar, Air Conditioning, or if you often need backup power, then you’re better off with a traditional gas generator.

- If your need for backup power is occasional and modest, then a CarGenerator is a better choice.

Customers Reviews

CarGenerator is a wonderful device. I had thought of purchasing a whole house generator (significant cost, space issues, _might_ never use it) or a portable gas-powered generator (noisy, fuel storage danger, constant refilling, might not work when needed), but didn't like either solution. Finally started thinking, "Gee, my car has gas, is safe and quiet, runs for hours and hours; there must be a way to use it as a house generator." The Internet immediately revealed
We got ours installed this past week with the home integration kit, and it works like a charm! So easy. Idle the car outside the garage, plug the generator into the house, visit our electric panel, flip one or more transfer switches, and our furnace, fridge, freezer, and/or sump pump is seamlessly running off the CarGenerator. Beautiful!
Finally, the company offers good old-fashioned warm and personal customer service. I post reviews only when I'm absolutely delighted with a product/service; only 4 in 3 years. CarGenerator makes it 5. I'm delighted to recommend CarGenerator to anyone considering an easy, compact, high-quality solution to intermittent power loss at home.

Tom Loveland

Jonathan spent time helping me installing a cool adapter and then we tested it all out. I was able to heat my house and run my furnace with this really cool device – plugged in to the my car battery. It’s so cool and I’m so impressed. Jonathan, you’ve got an amazing invention here. I look forward to seeing you again soon and enjoying some fine wine.

Kevin Howey

I have had a CarGenerator since before Christmas. Thankfully I haven't had to use it.
But I really wish we had it back in the ice storm of 2013, when my sister's power was out during Christmas day and into the evening.
A BBQ saved the day for the turkey, but if we'd had a CarGenerator at the time, we would have been able to have heat and light as well.
My favourite part of it is the fact I can keep it in my car's trunk, ready to use it in any weather if and when I need it. I was going to buy a full-on gasoline generator, but storing that would have been a royal pain as I don't have much room in my garage to begin with.
Also, I can't easily schlep a gas generator around, if it's needed somewhere else.
The CarGenerator literally goes where I go. I'm going to take it with me on car camping trips, as it's very handy for providing clean 110V for my laptop, etc.
I've tested it with my new furnace (DC variable speed motor, peaking at about 200W), and it works perfectly, with wattage to spare. It requires the installation of a 110 volt outlet, which is straightforward, but an electrician can help you if this is something you aren't confident doing.
Great for wherever/whenever you need power in a pinch. It's a great little device and very useful!

Jason Goodburn-Moffitt

My wife and I picked up a Car Generator from Jonathan in order to give us some peace of mind at the cottage. Power outages are more frequent and in the winter it can be quite cold. Definitely would not be fun in an extended power outage. Jonathan came up to the cottage and helped us install an adaptor for the furnace so we could still power it from the Car Generator during a power outage. It will also run our fridge when power goes out in the summertime. Worked like a charm and now we have peace of mind if we are up there that we can still keep everyone safe and warm.

Paul Van Der Zanden

We are now the happy owners of a CarGenerator which has to be one of the most impressive inventions I've seen in a long while. Jonathan delivered our unit on Monday and provided us with a demonstration of how the unit would keep our furnace and fridge running in a power outage. My husband turned on his 2010 Dodge van and the furnace, attached to the van via the CarGenerator and a 100 foot extension cord from COSTCO, started up. AMAZING!!! The unit is lightweight, compact, takes up no room. And no diesel fuel to store. So clever. It will save us during the next power outage - kinda' looking forward to one just to see it work!

Barbara Willitts

I bought one and my friend Jonathan Schloo came over to my house and hooked up a prototype, easily done by someone comfortable with a little bit of DIY. It works great, I had the furnace hooked up with plenty of power to spare so we also added the refrigerator too, still with enough power to charge phones and laptops, and run my wifi.
Next time there is an ice storm, which is very likely in this area in the few years as we move into an El Nino cycle, I will be toasty warm with all my modcons.

David Black

Jonathan is a genius and is sharing his invention with the world. We get many power outages here in Vaughan, winter and summer. It sucks! But not anymore! Jonathan’s invention has changed all that! This power pack goes were you go – cottage, home, camping.

Danielle Soullierre Sinclair

Exceptional, well-designed product. We're excited about the potential this holds. Great job!

Jeremy Swampillai

We first heard about CarGenerator from a friend and looked into it as the product sounded interesting. We think it's a terrific invention that really meets our needs. The CarGenerator can heat our house using either of our vehicles. Its compact design takes up less space than traditional generators and is light and portable to carry and hang from your vehicle. Jonathan is very knowledgeable, professional and down to earth friendly. We would recommend CarGenerator!!

Sandy Christeas

When the ice storm hit us this last winter, we took out our gasoline generator and… surprise it wouldn’t start. The gas was bad, battery dead and it would not start. I ordered this CarGenerator and jonathan the owner delivered it and also did a demo for me. He showed me how to hook it up. It ran my furnace, Fridge and Freezer without any issue. I am pleased with the product and recommend it!

Amazon Customer

I normally don't get blown away by many products but my friend Jonathan Schloo invented this amazing product that uses a something most of us already have - our car! He re-framed the car as 'power' and his invention can power up essentials in the event of a power outage. I watched in slack jawed fascination as my furnace and fridges were powered up by the car with house power off. Awesome! Wished I thought of it! Best of Luck on Dragon's Den October 4th on CBC. I love this thing!

David Andrew Smith

Received my Cargenerator last Friday and hooked it right up to my Ram 1500 . HAD TO DO A TEST RUN ! Plugged in my compressor and , tada , it fired right up ! Wired the furnace with the supplied kit and it’s ready to rock if and when we need it !
Great product and saved tons of money if I was to go the traditional route and get a gas powered generator ! Thanks Jon ....

Ernie Lansing

A few weeks ago Hurricane Dorian passed through NB Canada and luckily for us we had just purchased the Car Generator and were able to use it. Since it was the first time using it, we did need a few directives in starting it up but Jonathan was there to answer our call and easily walked us through it. Fridge scanned in at 161 kw and the Satellite TV at 262 kw and by using a power bar, were also able to charge our phones and whatever else needed to be charged. The best part of this is you can call the Company 7 days a week for assistance and Jonathan is right there to take your call. It is a life saver when you have no power and always have a vehicle in your driveway to hook up the generator.

Looking forward to power wherever we camp!

We probably aren't the typical reviewers. We don't own an RV and we don't live anywhere with frequent, storm-related power outages. However, we do tent camp several times a year and when I do, I prefer having certain luxuries (large fan for the tent during the day, bouncy house for the kids, espresso in the morning). Scoring a site with electric is difficult and expensive and these sites aren't always as pretty as tent sites. Using a gas-powered generator requires maintenance I don't feel up to and is loud, stinky, and expensive. With my car generator, we can now have all of our conveniences anywhere we go! And if we ever have something big happen, like an earthquake here in sunny SoCal, it's also comforting to know that between our car generator and two hybrid cars, we'd still have plenty of power for our important home appliances. Plus, the customer service is TOP NOTCH! I didn't know how to hook it up at first. I was grounding it in a bad spot so it wasn't generating the power I needed. Jonathan was super responsive, kind, and helpful. Really, it was the best, most personal and friendly help I've ever gotten over a product. I'm a very happy customer and can't wait for all of our summer camping trips!

Dave Lee
Great product for temporary backup power

Purchased to have backup power for essential home appliances (refrigerator, gas furnace etc). Tested out my unit and it worked well. This product is by far the best solution for someone looking to have emergency power on hand. Would of given it a 5 star review but experienced 2 issues. The strap locking clip broke that helps hang the device from your car. Nice if it had been metal instead of plastic. Bought the unit during a promotional sale and was supposed to get the Furnace plug kit. Never received it. Upgraded furnace myself using items from local home improvement store. Even though i had these issues, would still recommend this product. It provides essential power without the need for storing fuel and maintaining a large generator.

Kevin LeVan
Car Generator

Only had to use it once so far seens to work really well. I was suppose to get the Furnace plug kit for home or cottage with it but I never received it.

Great Device

I like the fact that I don't have to carry separate fuel for a regular generator.

Paul Bass
Good product

Well built quality product but if I had to do it over again I would have purchased The 1500/3000W so it could run my 1/3 hp sump pump rated at 9.8 amp. I was under the impression that the 1000/2000W Could handle such a load because the sump pump only runs for about eight seconds with just over 900W At start up for a split second and 800W for the remainder of the eight seconds. I even tried hooking the car generator directly to a deep cycle 12 V 105 amp hour battery that is fully charged at 13 V and the car generator will not run my sump pump. The sump pump and battery are one year old and the sump pit is crystal clear clean. My plug-in amp meter shows that the pump is using 10A.

Frans Van Diest
Great light car generator

Yes it really works, I tried it before we went to Mexico. We feel safe now!!
We had to buy an adapter 50 to 10 AMP for our 5Th wheel but now the connection is easy.
Thank you Jonathan for your great support

Kim Lasko
Home Run

The product meets all my expectations. Bonus was the great technical support for getting it to work with my furnaces setup. I live in a condo which does not permit gasoline generators (nor probably any other than battery). However, this works and meets the associations concerns.


Love it. Works as described.

Great customer service!

Bought my unit a year ago to use with my Airstream travel trailer and had not had a need to use it until now. I went to a 4 day music festival with only dry camping options and thought this would be the perfect opportunity to try out the Cargenerator. Set it all up and something was wrong. Not having familiarized myself with the operation as well as I should have before leaving home I was a loss as to why I wasn't getting any charge back in to my battery bank.
Since I was in the hills of southern Tennessee the internet connection was not great and I couldn't research possible fixes to my problem. So, I was able to put in a call to the company as a long shot to hopefully get some help. It was incredible to me that the owner of the company answered the call and was able and wiling to help me diagnose the problem. Customer service, for the products we buy on the internet, is so often lacking or not existent but this has been a wonderful experience that I could have never imagined. Jonathan helped me figure out that my problem was not the Cargenerator, which worked flawlessly, but instead was actually my Smartplug 50 amp to 20 amp adapter. After he diagnosed the issue and helped me find a work around, he contacted Smartplug and got me in contact with the right person at the company to get a new adapter that will work for my application.
Wow! Thank you Jonathan. Great product and top notch customer care.

Works great

It can power my house with the jeep wrangler hybrid,got to gently close the hood for the jeep to let you use the hybrid mode and disconnect the door wire for the jeep to run more than 30 minutes.the 1500 watts car generator run my vitamix blender and a 100w fridge at the same lights

Good Character in business and life is everything. Jonathan’s quick response and gracious attention to a customer speaks volumes for the character of him and this business. Oh, by the way the product is wonderful. Works as described.

Jon Sheldon
Simple, effective & it is what it says it is.

Such a simple elegant solution to back-up power - you’ll be using it in minutes.


I set up the unit for a test run with our RV. Instructions were good/helpful, but I am unsure that it will provide enough wattage to keep my bay of house batteries charged when dry camping/boondocking.

David Clermont
Dry Use Car Generator

I purchased this to use on my 2019 Chev truck for camping. I easily connected to the battery, started the truck and then pulled a controlled 900Watts easily out of the inverter and used this power to charge an EcoFlow power station. It will do 1000Watts but wanted to keep it just under the max. This works perfectly for my camping and remote needs and the Dry use is well built into the accompanying case including very well built cables. I look forward to further using this in the coming weeks camping and all summer and year. Dave C. Thank you.

Update to review dated 4/21/23

After I submitted my first review I was contacted by Car Generator to let me know the furnace plug was on its way. Received it today. Thanks for the great customer service.

Back-Up for Motorhome

Nice product

Peter Brubaker
Well made

I haven’t had a chance to try it, but it looks well made and the instructions are very straight forward. Delivery was fast and it was well packaged.

MC Sullenberger
Very Satisfied after coming with delay

Very well constructed device, and tested out well. Should fit the bill for temporary backup power. Order was delayed 7 days, since it was out of stock.


We have just unpacked it, have not needed to use it.

William Baio
inital impression

Unit arrived today. Looked like a brand new unit. Did a preliminary test and used the supplied watt meter. Tried a 5 hp shop vac. The unit powered the vac. Did not leave it plugged in for more than 15 seconds as the power draw was over 1 kw. Voltage drop went down to 13.1 V DC under this load. Static voltage with no load was 13.8 - 13.7 V DC. Plugged in a fluorescent trouble light with two separately switched bulbs. Under this load, the drop in the DC side was 13.7 V DC. Power consumption from 1 to two bulbs went from 9 to 25 watts. Vehicle is a 2020 Chevy Silverado 3 liter Diesel.

For it's intended purpose I'd say it's a pretty snazzy unit. I would suggest a glorified cup or eye hook to hold the S hook on the end of the strap instead of that thin screw. The S hook is not as secure as I would like it to be. I believe this is important because the strap is for all intents and purposes the lid that holds the jumper cables in place when they are stowed.

Lynn Hupp
Great Product!

What a nice change from a smelly, heavy, expensive gas generator! As a fulltime RVer, this is a great product to keep my RV battery charged when boondocking...or during extended power outages, which is why I purchased it.

William McKee
Backup for Rv

While researching generators as backup for my travel trailer a found the Cargenerator. No need to carry gas cans, monthly exercise and very lightweight. I purchased the 1500/3000w unit to be able to run microwave, toaster and coffeemaker while boonbocking. Tried the unit when it first arrived and it preformed beyond my expectations. Very easy to install and setup. I can also use the Cargenerator as a backup to my house during power failures.

James Otis
This Thing is Awesome!

I had some difficulty at first because the inverter on my RV had a wrong setting. I called CarGenerator Support. They were very friendly and helpful. They helped me diagnose the problem and told me how fix it. Since then, the CarGenerator has performed perfectly at charging my two 100ah lithium batteries and since my car is almost silent when idling, I don’t bother or upset anyone while charging!

I’m very glad I bought this generator.

New 1500W Airstream Edition

Works as advertised. Great addition to my boondocking arsenal of 550W solar, 300AH Lithium Batteries, 3000W Victron Inverter,
Champion 2000W generator, etc. Tested it out yesterday and will charge my batteries and powers my inverter which in turn powers my hole 25’ AS Globetrotter. Only will plan to use it if it rains/cloudy for several days and my solar is running behind in keeping my batteries charged. I highly recommend a CarGenerator and Jonathan was very helpful.
