Why Portable Gas Generators Are A TERRIBLE Investment!


Do you enjoy spending hundreds or even thousands of dollars unnecessarily when you don’t have to? Of course you don’t.

If not, then why would you EVER spend your hard-earned money on a portable gas generator when you don’t need to? Because… as you are about to learn, more than likely you don’t. You simply don’t realize that you already own one!!

Do you own a vehicle? If so, then you already have a perfectly suitable mobile generator sitting in your garage or driveway already!!

Generators consist mainly of two components: A) A gas-powered engine and B) an electric motor that is spun by the gas motor to generate electrical power.

Well that’s precisely what your vehicle is! Your vehicle is powered by a gas engine that turns an electric “motor” (your alternator) to generate electricity that is stored by your vehicle’s battery to start your vehicle and run all of its electrical components!

And the good news is… it’s not difficult AT ALL to quickly and easily transform your vehicle into an emergency gas-powered generator!! We can show you how HERE!

We can also show you how to save HUNDREDS of dollars (the cost of a gas-powered portable generator) in the process!!


Now just to be 100% clear, this article is NOT intended to be a criticism, admonishment or “slam” on anyone who already owns a portable gas generator!  If you already own a portable gas generator, GREAT!! Portable gas generators do exactly what they are intended to do: provide electrical power. This article is for those who DON’T have a portable gas generator already but are considering purchasing one for emergency power purposes. I simply want to give these folks an opportunity to consider another option before investing hundreds (or even thousands) of dollars on a portable gas generator when… they really don’t need to. So please, current portable gas generator owners… don’t take this article personally. 😉

OK, now back to the alternative option:

Imagine for a moment that you are thirsty and you would like a glass of water to drink.

Now… to pour that single glass of water, would you go to every faucet in your house and turn them ALL on FULL BLAST and then LEAVE them all on as you pull a single glass out of the kitchen cabinet, fill the glass up with water from just one faucet, take a sip… and then just LEAVE ALL OF THE FAUCETS ON IN YOUR ENTIRE HOUSE INDEFINITELY?? Simply because you know that sooner or later you are going to need another glass of water again??

Of course you wouldn’t. That would be absurdly wasteful and ridiculous.

The vast majority of us would NEVER be this cavalier about our water usage or be this blatantly wasteful with our water (We all know someone who loves those long hot showers in the morning, right?)… which, for the sake of perspective, costs about $0.0015 per gallon. (Average nationwide)

Now imagine that tap water cost $2.70 per gallon like gasoline does!! From that perspective, how does it make ANY KIND OF SENSE to run a gas generator continuously with NO REGARD for A) how much power your generator is generating for you that is going completely unused, and B)  how much fuel (money) we are burning continuously keeping that generator running just to power a few items??

Sadly, that is EXACTLY  what most people do when they purchase and use a gas-powered portable generator. They leave the generator running at full capacity just to power a few smaller items… or sometimes while powering no items at all!! What a complete waste of fuel and money!! This is exactly like keeping all of those faucets running full time all at once just so you can dunk your glass under the faucet periodically to rehydrate… only fuel costs SO much more than water does!! Is that really smart??

Not to mention that fact that even if money were no object to you, in MANY emergency situations fuel can become a scarce commodity and may not even be accessible to you at all no matter how much money you have and are willing to pay!!

Now back to our water analogy for a moment: Let’s pretend for a moment that our only option is to have all of the faucets in our home either A) completely off, or B) ALL of them on at once and on full blast. (I know, I know… just work with me here for a moment for the sake of our analogy. I’m making a point.) What then? Not having water isn’t an option. But turning on all of your faucets full blast just to get a little bit of water… that is a terrible option as well. Hmmm…

Well what if you had a large container that you could connect to ALL of your full blast faucets at once, fill with that container with water and never waste single a drop, and then once the container was full you could simply turn off all of the faucets and then just trickle out EXACTLY what you needed when you needed it from that container?? That would work, right? Absolutely it would! Wouldn’t that be much smarter? Of course it would!

So the “full blast water faucets” in this analogy are our power source (your current vehicle which you already own and don’t need to spend extra money on, or… you could spend money on a portable gas generator, solar panels, wind turbines, micro hydro etc. if you really want to). The “container” in this analogy would be… A BATTERY BANK!! With a simple DIY battery bank you can simply use IT to recharge and power devices, lights, etc. and only use the “faucets” (your generator) to top of your “container” (battery bank) again as it gets low! No wasted fuel!! NO WASTED MONEY!! 


You already have an amazing portable/mobile gas-powered generator sitting in your garage or driveway, and we can help show you how to set it up!

So you don’t need to spend more money on a portable gas generator.

And we can show you how to EASILY build your very own DIY emergency battery bank system to meet all of your power needs during an outage for a FRACTION of what you’d pay for a commercially made battery bank!

So let us help you SAVE MONEY and simultaneously GET COMPLETELY SET UP for any power outage!!
What are you waiting for??


Still having a bit of trouble conceptualizing the importance of power STORAGE vs power generation? No problem! We created an infographic to help clarify the matter visually for you!!

  1. Generator have much more efficiency at low power, than your car. Car alternator have too low power in compare with generator. Battery bank is many times havier than gas+generator for same energy.
    So, use a properly selected technology.

    • Mmmm… Yes and no, Viktot.

      While I 100% agree you that we should use “properly selected technology”, I would suggest that the critical (and often overlooked) distinction in this equation is failing to recognize the difference between A) power GENERATION and B) power STORAGE. Conflating the two is the mistake most folks make.

      For example, most folks that implement a solar or wind power system understand that you have your solar panels or wind turbines to generate your power, but you also have to have power STORAGE capacity in your system to use that power when the sun isn’t shining and the wind isn’t blowing.

      My point is that you can actually do a LOT more by investing your hard earned money in a stand-alone power STORAGE system than you can with a stand-alone power GENERATION system (with no means to store the power that you generated).

      A standard vehicle alternator will produce between 1000W and 2000W. 1000 to 2000W (peak) generators will run you between $500 and $1000 (if not more). So you are spending $500-$1000 to purchase something… that you already own. That money could be invested in a REALLY nice DIY battery bank so that you have both power generation AND power storage. Investing that money in a generator instead only gives you power generation with no storage capacity.

      You can do a LOT with a single 100Ah deep cycle battery. We use batteries every day for so many other things. Why not for emergency power? Doing so has the potential to save us hundreds if not thousands of dollars. It’s a shame so many instantly gravitate toward portable gas generators for emergency power when they could easily accomplish their emergency power needs without an additional unnecessary $500 – $1000 (or more) expense.

      • running the engine attached to that automotive generator will cost a LOT more than running a 2000 watt generator – and a 2000 watt generator OR your battery bank will not handle 240 volt loads (north America) You need a 4000 watt minimum to get 120/240capability – anything less is a bit of a waste.
        Also, automotive generators rated at 120 amps will put out about 1500 watts – for a limited amount of time before burning out. In a car they put out high amps for a short period of time to recharge a 70amp-hour battery. Then they “idle” at about 50 amps providing for the load of lights, accessories ,and heater/ac fans. They do NOT work well as chargers for mega-sized battery banks required to provide long-term power backup.

        • It would indeed cost more to recharge your batteries with your car than a portable gas generator… if you were actually running your “automotive generator” like people tend to run portable gas generators. But that’s not what I am advocating for here, Clare. Adding a battery bank to your equation would prevent you from having to do that. That’s kind of the greater point of my article. I fully acknowledge that your car’s alternator is not nearly as efficient or equipped to do the job a portable gas generator is designed to do. But when you have a battery bank in your equation, you don’t NEED to use your car alternator like a portable gas generator. That’s the point. You are approaching this scenario from a conventional portable gas generator mindset. The equation is completely different when you actually have a power STORAGE capacity and only need to top of your battery bank occasionally once it drops to about 70% capacity. Your vehicle’s alternator is more than sufficient to achieve this. You are too focused on power GENERATION and not looking at how having a power STORAGE capacity would be a game changer. It truly changes the game in terms of how much emphasis needs to be placed on power generation.

          Notice that this article does NOT advocate for just skipping a portable gas generator AND a battery bank. If I was truly advocating for just using your vehicle as a portable gas generator, then why do you think I would advocate for a battery bank system instead? Why not just use your vehicle as a portable gas generator and skip the battery bank expense too? But I’m not doing that. And there’s a very good reason for that.

          Portable gas generators absolutely perform better as portable gas generators than cars do. But when you add a battery bank into the mix, you no longer need power generation capabilities like most people think they do (running the generator non-stop so you have power at all times regardless of how much they are actually consuming at any given moment). The battery bank allows you to draw power little by little only as you need it. Then you simply top off your battery bank when it is at about 70% capacity. With your vehicle’s alternator. Saving $500 or more in the process.

          What I am describing is a completely different mindset. But it works. I can assure you. You simply have to be willing to forgo a little bit of what you already know and be a little more open-minded to truly see the potential of what I am describing. You have to grasp the impact having power STORAGE capacity in your system to realize that power GENERATION becomes a lot less important. It’s truly not dissimilar from when individuals get really excited about solar panels and wind turbines for off grid power… only to quickly discover both of these cool power generation devices are virtually worthless until they are coupled with a battery bank to STORE that power for when the sun goes down and the wind stops blowing. 😉

          So yes, you are right… portable gas generators are much better at being portable gas generators (imagine that!) than vehicle alternators are. But you are missing the greater point here: The efficiency and power output differences between a $500 – $1000 portable generator (an extra expense) vs. your car alternator (something you already own) matters far less when you become more power STORAGE centric in your approach to emergency and off grid power. You only need brief power generation/recharging “sessions” to top of your batteries again. Because your BATTERIES are the hub of your emergency power system as opposed to your “generator”. See how it’s a bit of a paradigm shift/mindset change there?

          I hope that helps!

  2. Battery banks are much more expensive than a 1000 watt generator. That cost is $ 69.00 at harbor freight. A 100 AH battery will cost you 5 times that and will require weekly maitanice and the ability to charge. The person that has a battery bank and the generator owner both want the same end result (off grid power) with very different ways of accomplishing that goal.

    • Actually Mike, you can get a 100AH deep cycle marine battery for just over $100. Albeit not the best quality battery, but in fairness… that “$69” Harbor Freight generator isn’t really the best quality generator either. Regardless, even at $69, my point is that it’s still $69 that you are spending unnecessarily on a generator because… you already have one sitting in your garage/driveway. Batteries also don’t require “weekly maintenance” if you simply leave them hooked up to a quality charger.

      I think the greater point that is getting lost in this discussion is the difference between power GENERATION and power STORAGE. If you invest in a generator, all you have is a power GENERATION mechanism with no means to STORE that power. If you invest in a power STORAGE solution, you already have a power GENERATION device sitting in your driveway, meaning… by default you will have power generation AND power storage capabilities now. And many folks are completely overlooking this dynamic by immediately gravitating toward a portable generator. I’m merely suggesting that people consider power STORAGE as an important variable in this equation. A variable that I would argue should be prioritized OVER power generation for the reasons that I have laid out.
