600WH / 35W = ~17hrs. You're welcome.

Thank you much for great info in this. It was def worth mentioning the required deep cycle capability of a battery, for this type of irregular re-purpose.

Brilliant video mate..Thanks heaps! Best regards from Western Australia.

I really appreciate you sharing your deep cycle knowledge.

I am looking at walking the neighborhood a few hours / day with a vendor cart and I need mobile AC power where setting up a generator is just not feasible while walking and pushing a cart. I know the power requirements of my equipment (about 50 watts total, continuous). This video was very helpful knowing I can do it -- apparently better with a marine battery. If this doesn't sound correct, please advise.

Gracias compadre! eh visto muchos videos pero esta vez lo explicaste bastante bien claro!! Gracias!!!

you are right about the math and about not killing a regular battery, but "super quiet", LOL... There is no way to have that in an apartment...

Well.. it’s good to have this man as a dad. Doing all the homework.

I'm thinking about splitting my home installation into two backup systems; one using conventional car batteries (two at the moment) for lights and very low power draw appliances connected to low power cells. While I use lessons learned to build a more powerful second system perhaps at 48V that hooks up to an inverter. In this way, any catastrophic failure at either end still allows for backup, and more importantly, if fuel will be come scarce, I always have a car battery ready to go no matter what. My plan is to adapt my trucks to use lp gas so I can later fall back into home made natural gas. But then, I'd use them very rarely if it gets to that, so having an infrastructure that allow for this is critical. Additionally, I'm trying to get equivalent appliances that are 12V and getting a USB charging laptop is a key part of this. Having a gaming laptop is fun, but will certainly be unusable for the most part if I'm cornered into my backup backup lighting system. I also expect car batteries to be more common than specialized Off-grid batteries as time goes by. Still, going solar (not electric, but solar) is useful. Wood, gas, and other sources that can be harvested locally ... so many skills to develop while simultaniously, learn about the changing web and its traps as they begin to lockdown our system. My guess is that they wish to destroy the foundation of the web as we understand it(anonymity, interoperability, free exchange of information across the globe) ... all those privacy regulations will most likely be weaponized as they roll off those digital currencies and start with those advertised false flag blackouts (hopefully they won't but didn't those WEF crooks say something about digital COVID and blackouts?) Anyway... food for thought

Awesome video. I would only use this for my cable modem. And only when the power goes out and use it occasionally to check the weather. And deep cycle is probably the way to go.

Yay! Thank you for making this video! I love the detailed breakdown and explanation! Much appreciated! I just found your channel so you may have videos that show running an instant, airfryer, toaster oven etc. Anywho.. that would be super interesting

You inspire me to learn how electric systems work you are absolutely awesome. You know a lot ! Thank you for all you do and share 🙏🏻

Thank you. You are the first person to use a walmart battery. I use walmart batteries and they work ok. And you explained cca. Good video

Thanks for the informative vid. I just purchased a 1.5KW generator with 1200 W peak and 800 long-run. I will use it from my garden in case of a blackout - its too loud to use in my apartment so i was thinking of getting some deep cycle batteries which I would load during the day and after 9PM would sitch to the batteries to power the fridge/ tv/lights and charge phones and Bluetooth speakers. Agreed on the inverter choice = don't go cheap.

Love your video! I've got son & daughter's old car batteries I've swapped out for them lying around charging up. Both are around 43ah 50ah. I'm going to be using them for LED lights around the tents when camping this summer and also charge our phones up. I'll be connecing a USB adapter for that which are 12v input and whatever (5v) USB. Everyone is excited......we have even got a small 5w solar panel. Have you got any advice on safety like fuses? I will watch and nurse the system and disconnect everything before we go to bed but should I use a fuse box and would a 10amp fuse do the job?

Great video. Pure sin wave inverters are the way to go, esp, to backup a pellet stove or furnace.

LOVE THE MATH. So simple and so clear. YES, in my case, running my TV off battery is far more efficient than electric. I live on a remote island in southeast Asia and the grid goes down OFTEN. Solar backed with grid makes a super simple but stable system. Thank you

Great video, was so informative, thanks.

I'm curious, some tv's come with power adapters that take the voltage down to 12v ?a. How long would the car battery last if the inverter was eliminated.

Thank you! I didnt know the difference between a car battery vs deep cycle. I am looking for a set up to power a fridge in the event of a power outage. Can you "charge" a battery, deep cycle or car battery with a jump starter? I have a dp power jump starter. If the battery dies, there is no power, how do you charge it?

Thank you very much and it was very informative.

Thanks for outlining the math on this. Looks like the solar inverter is pretty equivalent cost-wise

Excellent video sir!!

Thanks for the video demo but if I have let's say a deep cycle gel battery is it also ok to use it on small appliances like a tv rated at 35w or a fan rated at 18w , can I also make the battery as a powerbank and does it have the same storage life as car batteries? Is it ok to just leave it unused for a month and just use it when the power is out? Thanks

Whats the brand of your inverter generator?

great explanations Thanks a lot

I got a AGM battery is that the best of both worlds because it has the cranking amps and from what I understand it's recommended to keep it about 50 but if you drop it under 50%, no damage to the battery

Great job explaining the math. I would have divided the inverter watts by 0.85 and use that as the input to the inverter because that's what's really going on. But the math would turn out the same. I've been doing this technique for several years because when we have a power outage at our house it's usually only 2 or 3 hours. keep in mind that besides the TV you typically would want to fire up your Wi-Fi and Internet modem which are both low power devices also. I also rearranged the breakers in my panel Box so that those 3 loads were on the same leg and I use a male to male plug into an outlet also on that leg to my life easy with no extension cords.

Thanks for the info great job

Another question. Is it better to use a portable generator?

OK. Would possible to power a pressure washer (greenworks 1700psi/1.1gpm) off a deep cycle "D4" car battery for moderate amounts of time?. What kinda setup would you recommend as I'm a mobile detailer.

so will a UPS/Surge protector protect your sensitive electronics? from the uneven voltages if you have to run an old fashioned NON inverter generator?

Cool video. I just bought a couple 12v LiFePo4 batteries, gunna have two more coming soon. Was thinking of putting them in my old cars outside somehow, to charge them in an end of days situation. Fun times!

Very clever, and my head hurts. Also, I probably don’t want a gas (petrol etc) power inverter.

Hello, I would like to know that: if I connect a "lifepo4 smart charger to the wall 110V socket" to a "30Ah lifepo4 battery" and then to an inverter, I come up with some kind of an automatically switched and operationally save UPS. Thank you for your response.

So I have a group 34 Optima Red AGM battery which means I should be fine with using my back up battery then? I mean from my rudimentary understanding of how various batteries work an AGM is a deep cycle battery but not a marine battery due to not technically being rated for possibly being submerged or getting splashed? I mean it is a no spill battery so I'm guessing it's waterproof to like maybe a meter.

For a cold crank to last as long as Deep cycle it's said add a capacitor between the battery and inverter?

Cool thing that goes towards the battery side, is with solar you can recharge a battery without having to go to a gas station and get gas. With battery and solar charger setup its quieter and has less moving parts and replacement batteries after they go bad are a lot less to replace then a moving parts probably going to break something over time generator that probably wasn't designed to run 24/7 365 if someone was to setup a DIY RV or tiny home, cabin etc. Also with new Lithium based solar batteries the actual amount of power you can drain is a lot better than lead acid or AGM based deep cycle batteries. So I guess it all comes down to use scenario, long term the generator isn't a good idea, but having a generator combined with solar for cloudy day charging then you can power that TV as long as you want off the battery.

Watching this after hurricane ian knocked out power at my house a few days ago.. hearing the loud annoying generators for 20 hours was enough for me to look at alternatives. This would easy power s few fans and charge some phones during a power outage

super quiet generator indeed :))) it sounds like someone is driving a motorbike inside your apt. :) but great video thank you for mentioning when playing tv while the car is running that's what I wanted to know, I also wanted to know how many or the max devices that you can run/power on a car battery while the car is running, I didn't find any answer for that question until now. i looked everywhere no luck.

Hey, I came here from the solar panel videos :) So my obvious question would be, Could it be efficient to use solar panel to charge the battery and then use it to run the TV (or any device at home)? Would the battery run out faster then it charges ?

Awesome info

what the thing called at 8:00 with the clips to the battery and the powerpoint

Why cause the distortion on the tv? Will a normal inverter to that?

You .mentioned car baTteries are these deep cycle like RV or starting battery

Can i use the bolero pickup battery for tv power bank??,and what is the inverter watts can be used for tv???

I connect 12v/100ah 820A battery to a charger and inverter but when i turn on the tvI’m hearing a high noise from the tv any idea. And is it safe and normal ?

Than k you for all your info. about this subject very usefull when you play with 12v devices hope in the future you share your knowlege. I did suscribe to your chanel

Ty sooooooo much! Finally someone explains it efficiently. Is it ok to use a deep cycle battery as the car battery?

Using the same for electrically independent garden lighting, using a 300w inverter... Standard 70ah 663cca battery. Better than solar power lighting, as solar gets dimmer over time.

How about if you plugin a mains car battery charger to a generator, then connect the charger to the battery while the invertor is running off the battery, so you are converting a non invertor generator into an invertor generator so you can safely run electronics like computers in a blackout. Would the battery charger keep the battery topped up like running a car engine with the invertor connected?

Hello I have question, is it good for power station AGM battery? We have here available in UAE Toby's battery, is it same performance like other portable power station? Please help thank you stay safe all.

You lost me at the math my friend. I understand why you did the problem. So, at the end are you getting more with the generator or battery per CCAs? So should I buy the battery and sine inverter or the gas generator? Still not sure.

I'm going full solar ( i'm tired of spending money on electricity ) and i was wondering if this were the bateries that i needed to use on the sistem to use on night time, i guess they aren't, thanks very informative video

What’s the runtime of 2kva ups on 240Vac with 7A load 1700w

It's called Square-wave vs Sine-wave or modified. Inverters don't do too well with LED lighting either, because of the wave form issue. An inverter powered 10 watt rated 120 Vac bulb will have about a 30 cycle flutter rate which is quite annoying. Also, most 12v LED lights usually need a minimum of 11.5 volts to operate; they just cut off all together, as opposed to an incandescent bulb which will just get dimmer as the battery power fades. This also affects an inverter regardless of the type wave form it produces. If your battery falls below 11 volts, the inverter usually cuts off. You have 11 good volts in there which is unusable.

Super helpful!! Love the math break down

Do you have to recharge the car battery ran out?

I suck at math but I got it 😂 The main reason why I think many people take an inverter over a genny is the massive difference in price. A cheap genny is about 3 times the price of a good inverter, at least in my country. But I'd much prefer to have a nice, portable generator

bro this video is what i get for skipping school today i came to watch something kinda cool and all i was told was math the entire video

This is all very confusing. I am considering living in a bus and want to be able to run a high performance computer for gaming and VR. I would need at least 750 watts (closer to 1000). Want to run it off a battery or generator seperate from the solar system power. How can i do that?

This is why we have 200ah LiFePo4 batteries, with inverter, charged via 200w solar (soon to be 400w) for electric supply to our tankless gas water heater, two LED can lights, fan, and wifi connection. THEN, we also have a generator (soon to be a honda) for refrigerator etc. Utilize multiple sources of power to diversify in our levels of emergency planning. Also looking to add a propane option for the generator as well

thank you :)

This guy just gave everybody a math lesson we didn’t come here to get just plug the fucking thing up and let it run until the battery dies and there’s your fucking answer folks

Can I ask why you would convert DC power to AC power just to have the TV convert it back to DC voltage for use? Am I missing something?

So how many hours?

So to power a TV & ps4 in the back of a van what would you recommend? Car battery or inverter generator?

10:00 wait a minute when the TV don't have anything playing on it all the LEDs are black none of them are lit up which is why it's only pulling 30 watts right? If there was something playing on the screen it would probably pull 125 or 150 at least I think because the screen would be lit up instead of black. Maybe I'm wrong but if the screen is black even though it's on none of those LEDs in the TV are lit up. When the power's out for short periods I use an inverter to run my TV and satellite but I leave my pickup truck running if it's really only pulling that many Watts I could leave my truck shut off for hours at a time......

Thanks!

That's not distortion it's the capacitors burning out from the modified sine wave..... lots of TVs don't like them...... This will not happen if you use a pure sine wave inverter.

How can I wire a soft wash pump to connect to a generator instead of directly to car battery?

That's good to know thanks

What is the power requirement of the TV internal circuits? Don't most TVs convert A/C input voltage to DC to power the circuits? If the internal voltages were 12DC, couldn't you bypass the internal inverted/transformer and power the internal circuits directly and not lose the 15% inverter loss?

Hi How to set up a mobile tire change van with 1500w inverter powering 1500 w air compressor + 1050w tire changing machine ? 24 gallons air compressor gets full in aroud 4 minutes which is enough to fill 1-2 tires , meaning air compressor will have to be filled 2 -4 times per car . Tire changing machine will probably work for 8 minutes per car. 120 ah battery should fill air compressor and still have about 75 ah left after it. Once 1 car is done this way then van will idle for 10 minute while packing tools and then travel to next car for about 20 minutes + can idle for another 10 minute while getting tools out for the next car. Wonder how fast can van's alternatot recharge battery while idling and driving for this kind of time intervals. Ford transit 2004 , 2.0 tdci, fifa, 92 kw i think it has 105 a alternator . Where to look for larger alternator if it can be installed ? Thicker cables as well ? Thanks !

I want to get on a stationary bike, or treadmill, and power my TV while I watch a 1 hour episode of Star Trek. Can somebody please give me a list of what to do to get this accomplished?? All I have seen so far points to a generator and a 12v battery...but I dunno how to put any of it together.

Can I also use a beamer and a laptop?

Did you say how long the battery would run a TV? Withball that info, how about a range?? 2 hours to 4?? What was it??

Nice cross cut sled!

how many decibels from the inverter generator

Great video dude! In my preps I have an invertor which I use between the times that the generator is running, at which point I also charge the car battery to keep it toped up. I figure it's less efficient to keep a generator running continuously if it's just to power low wattage items.

3:00 the purpose of leaded car batteries is different , thyr meant to turn an engine . you can still get low amp and voltage applications for them :) here is an interesting fact :

Thanks

Yeah I was living for $400 a month in a four-bedroom house and they pay the utilities and tell somebody about since 2013 now somebody finally bought the place but they're going to take it all the way to the look around the house

Not many people have a LiFePO4 battery as their car battery, and if you don't then you only have HALF of the stated capacity from your calculations. A LiFePO4 battery can use 100% Depth of Discharge with no damage and last thousands of cycles. FLA/SLA/AGM will only last a few hundred cycles if used properly, meaning never going below 50% DoD, because if you do you are risking severe damage to the life of the batteries. Calculate your AH and then cut it in half, not for the purpose of starting a vehicle again but for the purpose of avoiding guaranteed damage to your batteries. Also, never EVER use a modified sine wave inverter on sensitive electronics such a computers, TV, etc. Pure sine wave inverters are more expensive, but there's a really good reason for that.

Hi! FYI, I didn't watch the whole video... 2 much math lol... My question is simple. Approximately do you think a healthy new or used car battery would power my Optiplex 9020 PC tower and my 38" Alienware curved monitor for more than 2 hours?

Most electronics run on DC these days anyway. I’d be worried about electromagnetic interference though. Big problem for touch screens.

Probably simpler to measure the amps direct from the battery itself. No need to account for invertor efficiencies, AC power factor etc. Just amps from battery to invertor to get the expected duration,

I understood the math till 0.476. But didnt understand why we had to multiply with 0.55 gallons which is the fuel capacity of inverter. Could someone please explain

What is the tv watts?

Inverter generator sounds like an explosion hazard while a car battery or golf cart battery sounds harmless. Inverter generator requires gasoline . Most storage units won't even let you store that

all i wanted was the math, thank you

THANKS,,,,

You cant use a gas powered generator indoors, so how does that work?

I seen an outdoor swapmeet setup with a similar 32 in tv and a retro NES both hooked up to a car battery. They do this every weekend with the same looking battery. I doubt that they would swap a battery out every 10 uses

I use a car battery for my TV and it only last 2 hrs. Dam you have a good battery.

We used to do that when our huose's power

I think your 800 watt inverter is pulling far more power than is necessary. Try the same test on a 2000 watt inverter, and compare to the results from the 800 watt inverter. I doubt the two will be even close. Those inverters have to produce power that can jump up to the max rating at a moment's notice. They have internal capacitors that hold power for this purpose. And keeping those capacitors topped off throughout the entire runtime is going to waste power into the environment usually in the form of heat.

Future TV's should be manufactured with rechargeable battery plug in features. We live in a world where we have battery operated lawn mowers which work fantastic, I have a Ryobi lawn mower, works great and goes plenty long enough on 40 volt battery. Same application which is used for power tools should be considered for Televisions and every house hold electronics. Well, space heaters, would take alot of genius thinking, to battery power them. Let's start with our big screen "smart" TVs.

SIR I LIVE IN THE BACK OF A BOX TRUCK, I GOT TIRED OF PAYING RENT, NOW I PAY NO RENT NOWHERE, AND IVE GOT 12 CAR BATTERIES I BOUGHT FOR $15.00 A PIECE IM JUST GOING TO DAISY CHAIN ALL 12 BATTERIES PLUS TO PLUS AND NEGATIVE TO NEGATIVE, AND WHEN THEY STOP WORKING ILL JUST THROW THEM OUT THE BACK OF MY BOX TRUCK TOWARD THE CURB, ? HOW LONG WILL ALL 12 BATTERIES LAST ? P.S. IF YOU SEE A CAR BATTERY ON THE SIDE OF THE ROAD IT WAS MINE OK THANKYOU! OWENS.

They have 12 volt tv 40 inch. Solar is key to freedom. No inverter needed.
