Power station cigarette lighter plug to boost battery

[undersc0re]

I am looking to make an emergency vehicle booster kit with cigarette lighter plug with short wires attached to battery clamps, fused of course. Would this work from my bluetti 1500 cigarette lighter socket safely to charge up my vehicle battery enough to start it? Would be nice to have just in case! I do not carry around a solar panel with me and pack as little as possible to remote back country spots with no cell service so it would also be a great peace of mind for me as well!! Wondering if anyone has done this before, I was thinking it might try to suck too much juice and blow fuses or the power station might cut out.

Buy a purpose-designed lithium jumpstarter

Recharge it from your larger powerpak, or even better, recharge them both from the same charge sources

mains charger when grid power is available

off grid:
vehicle alternator + DCDC
solar panel + controller
generator + mains charger

You will kill your Bluetti if you try Boosting a vehicle with it, You can charge a booster pack from the Bluetti but don't ever try Boosting a vehicle from it,

A Cigar socket or plug can only handle about 10A with a maximum of 15A, To Boost a V8 or Diesel takes about 300 to 700A So you will burn out the wiring in your vehicle, Or you could end up burning out the whole truck. So what you are asking is a real bad Idea.

If you are running a V8 then the Noco GB-70 would be the go but if you have something like a Powerstroke then you will need the Noco GB-150.

With one of our cute Lithium/Lifepo4 Battery Box solution (with different names and specs) we have one option to help our starter battery:
- use a Batterycharger (like ctek) over our embedded 110/220v Inverter

This is no solution who is quick, it need hours and depending on your battery box size - it can also not work at the end, because the ctek need to run 12h.

I suggest to use a jump start device, which you can too use as battery bank. Like the Antigravity Batteries XP-10 HD or Noco GB70 Boost HD. Depending on your vehicle engine. My 4.6l V8 Diesel crank but dont start. testet. I was suprised that the engine crank anyway, with a real flat battery and just a jumpstart device.

With a V6 Diesel or V8 Gasoline it will work.

Lesson learned: for V8 Diesel engines - you need something bigger, like your mechanic use.

I would only intend to let the car battery charge for an hour or whatever it takes if I am stranded. The battery is a 1500Wh with a regulated 12 volt 9 amp cigarette lighter output. I would not leave it connected when I try to start the vehicle. It is a v6 gasoline engine, I do have a very slow rate battery charger I guess I could pack along, was just seeing if my idea was possible.

The Noco GB150 will start a Semi, I have also used it to run my fridge for 4 hours.

"a Semi" is that an V8 Diesel?

Thanks for adding real world testing results!

Then your best bet is to use a 120/240v Charger plugged in to your Bluetti, A 10 or 20A charger will run for a few hours being powered by your bluetti and 26A smart charger will draw about 250 to 350w from a 240v socket so your bluetti should run a charger of that size for 4 or 5 hours which is way more than enough.

Guess at this youtube tests, a lot is "variable" - because a flat battery can still have some juice, or not...

I did try after let my lighs on for 3 days (accidentely) - she was completeley dead.

I Have seen the GB150 Start a 7.3 PowerStroke with the Battery/s Removed, So there is not much the GB150 won't start.

 

[undersc0re]

Gb150 is $450 cdn plus tax on that. I think I will drag along my little 120v ac to 12v dc charger with me I guess until I can find confirmation on getting a portable power station to charge a car battery on its own. Thanks for all of the input!!

One time I had a dead battery on my astrovan, it wouldn't crank over. I had one of those 18ah agm jump starter but it was also dead at around 12 volts, it wouldnt crank over the van, but I left it connected for about 1/2 hour while I decided what I was going to do. I decided to crank the van over one last time, and it crank slowly but it started. The agm jumpstart put just enough amps to give me one crank.

In an emergency, I think your bluetti can put enough amps into your battery to start it, but it might take 1/2 an hour. But to improve your chances you can always build a boost/buck converter to turn the 12.6 volts from the bluetti into 14.4 volts to give the start battery a quicker boost. On my van I use a boost/buck converter to top off my start battery from the house battery every day. No need to buy a jumpstarter unless you need the engine to start right away.

This boost/buck converter will turn 12 volts into 14.4 volts at 6 amps, and will give your lead acid a quick boost.


There have been times when my start battery was completely dead and it wouldnt jumpstart and have also encounter situations where I tried to jumpstart someone with jumper cables and there car wouldn't start because the battery was completely dead. Thats one reason I don't even carry a jump pack anymore. I carry jumper cables and I also carry a small oddysey 16ah agm, that I can use to jumpstart my van or if the battery is completely dead I can just use the oddesey as a start battery it has the side/top posts, the oddysey is a beast of a battery for its size.

jump packs are good. booster cables to a running vehicle better. a good battery is best, they usually last less than 10 years, get your tested. and when not running, disconnect ALL the draws. dual batteries and battery isolators are great til they fail. a dual battery switch works and never fails if you remember to use it. I keep everything RV separate from the vehicle. And test the vehicle battery annually.

relying on technology is only cool if you are near the tech guy for backup, if you travel off grid, keep it simple, keep systems isolated

one last thing, electricity voltage drops the longer the run and the smaller the wire. there is a reason the battery is close to the alternator, to shorten the run. and while in theory you should be able to charge thru the cigarette lighter what happens if all your fail safe protections fail..... what if you start the car with a dead battery and it pulls power thru the cigarette lighter wiring. keep it simple. if you need a boost or charge, connect directly to the battery. and disconnect when done.

IF he does as you say and use his Bluetti to try and Jump a Vehicle You will have cost him between 1200-2000 Dollars or more, It is a proven fact that Solar Generators "Can Not" be used to start a Vehicle, So please stop telling people that,

The Big Noco costs around 3/400 dollars thats a lot cheaper than destroying a 1200-2000 dollar bluetti, As Proven by experts the only way to boost a Battery using a Bluetti or any other Solar generator is to plug an AC/12v Battery Charger in to it.
