I own one and have used it several times on motorcycles. It works great. If you do run your battery completely dead all you need is another car and use their 12v plug or their battery terminals then bring it over to your car when its charged. Also, it can be charged from a micro USB port. I used a small USB power bank to charge this jump starter. It took about 5min. I highly recommend this product.
Cool
would it be feasible to just wire the super cap right into the system and just start the car every time from it? Would it get harmed if always connected?

Since it is not possible to create or destroy energy, the theory behind this device is that it transfers some of the remaining energy (watt-hrs) from the almost dead car battery to the capacitors. During this transfer some additional energy is lost to heat energy due to internal resistance. Once charged, the capacitor bank has a much lower resistance than the car battery so it is able to “give up” this energy in a very short burst (period of time). The voltage of the capacitor bank can never charge to a voltage higher than the almost dead car battery. The reason the car will start at this lower voltage with the capacitor bank and not the battery by itself is due to the low internal resistance of the capacitor bank. Simple ohms law and power equations.
"there's one thing i can really do well - that's to kill a car battery" okay... u got me on this. 😂
hahahahah - glad you liked!
Ive had one for about 3 years. I have jumped off so many people's cars with it. Great product.
One of the problems with the lithium based ones is that they get charged and stay charged. Lithium ion batteries are not long term storage, they are great for shorter term.
A lithium battery stays healthy when you charge it, use it, then charge it again. Best life keeping it between 30-80% charged, as both ends of the spectrum decrease cycle life. Charging it to 100%, then letting it sit there for months in the truck of the car kills the battery, so when you need it, it appears fully charged to the controller (based on voltage) but does not have the capacity needed for working (battery drains very quickly).
This eliminates that problem of long term storage expectation of a lithium battery.
I have a similar product, which is rated at 500A. It would not start my 103 cubic inch Harley Davidson V-twin, but did start a 1.5 litre Suzuki Swift (more cylinders, but smaller pistons, so easier to crank). I'm considering buying the AUTOWIT 1000A model for an extra unit to keep in the family. The good thing about the super capacitor jump starters is that you can never predict when you will need them. From when I bought my very first S/C jump starter, it was 3 years before I needed it. There was no way I could have kept a lithium battery jump starter on charge for this unpredictable day. Even after using my S/C jump starter, it gives me a wonderful sense of satisfaction, despite myself doubting that it can actually do the job. If the AUTOWIT 1000A can start a Harley Davidson, then I'll be happy.
Thanks for the review and I almost went out and bought this item yesterday morning when my car would not start due to I left the vehicle in the accessory mode overnight and drain the 12V battery down to even the interior light or power windows will not operate at all. After reading the PDF file of the car, I learned that because it is a HEV (hybrid electric vehicle) so before attempt to jump start the battery what I needed to do is to press the "12V Battery Reset" button next to the dash, step on the break, press the “START” button and to my surprise .... THE CAR "BOOST" THE BATTERY BY ITSELF!! According to the manual either driving or idling the car with or without the gas engine kicking in or not, as long as the vehicle's power in "POWER ON" status the onboard hybrid battery will take 30min to fully charge up the 12V battery in the engine bay. I may still buy one of this SuperCap for my regular ICE (Internal Combustion Engine) when Black Friday comes just for backup even I do have CAA.
Great comment - what kind of car?
@@Kitearmy It's a KIA NIRO Hybrid Electric Vehicle (HEV)
@@Jeo-What That's so cool - I have a Volt but I don't think it has that feature
Kite Army I guess they did not put the extra design feature into it.
@@Jeo-What Nope - never had a dead starter battery yet - I find it funny that we have these huge batteries to power the car but it still requires a 12v to start.
Thanks for the vid I got mines and it start my van like a champ
Great to hear!
Before you buy, you should first check out the video on Project Farm about jump starters > ruclips.net/video/ixWPx79g3yk/видео.html
Thank you for the video. Long time ago I saw a video someone making a DIY product like this and I thought it was fake, but is actually a true. I just bought my now.
cool
@@Kitearmy 👍😁
You said some amazing things are coming in the e-tool market for next year. How about a video on your predictions/insider knowledge.
That's a great idea! Trust be it's gonna be BIG!
I wonder how long it will turn the starter when fully charged
So theoretically a 10k milliamp solar powered battery/phone charger to charge capacitor via usb then jump start car??
that RadioShack voltmeter is OG.
Miss that place
FYI "solid-state" does not mean without chemicals. It generally means it's a semiconductor usually containing diodes or transistors, more specifically they have a junction between 2 or more N and P materials. So generally capacitors are not considered a solid-state device. You could say it is a static-state device I guess.
Contemplating on whether I should cancel my yearly AA subscription (I think it's called triple A in the US) 😂
No mate - keep your Alcoholics Anonymous subscription - never know when you will fall of the wagon :)
Can you use it to charge iPhone too?
Just curious, how many seconds can you crank the motor before the SuperCap runs out of juice? What happens to the unused energy stored in the SuperCap after the vehicle starts? Is there any danger?
You have about 1 min to start the car - the power in the battery dissipates after a few hours - so no danger
@@Kitearmy What battery?
Trick the shorting resistor to start up a dead battery!
I bought this product and I found it won't start up with a completely draind battery.
But search the video title on RUclips,
"StartUp Engine with Autowit SuperCap2 & Smartphone without Car Battery"
I hope you should try this way before you throw away this product!!
Awesome video u sound like a door to door salesman love it get urs now while supplies last
Thanks mate
get one of those little $15 solar panels and put it on the back dash of your car to keep this thing charged
Great tip!
Wow. That would be a party of two LOL. You like to run wide open mate
Wide open and mask off!
I have one of these, it does not charge a completely dead battery. Otherwise it's pretty good.
True
Good video. I just purchased one a few days ago. My battery was completely dead and unable to charge the unit. I charged the unit to 100% using the cigarette lighter from another car. The charging was within a few minutes and I thought good to go. Placed cable connections on dead battery and nothing. The unit never recognized the connection to the battery. Am I doing something wrong with the cable connection to the dead battery? Thanks.
I think there is a mode to jump a totally dead battery
@@Kitearmy thanks
Just a quick follow up. There isn’t any doubt that with a completely dead battery the Autowit will not work. The unit will not recognize the battery after battery clamps are applied. I called AAA to come and check the battery as it was still under the three year warranty. They determined the battery was fine along with my charging system. He used a Norco GB 150, 3000 amp jump starter and it worked flawlessly. I then tried my Autowit and the product worked as advertised. Since I don’t drive that car much, I will pick up a Norco 5 A trickle charger to prevent this from occurring again. Maybe even a GB 150 2000 amp unit and return the Autowit.
I have one and never fail me. Also no batteries to worry about
great ot hear
After replacing two lithium based jump starters when they were 2-3 years old and no it's time to replace one of those replacements at 2 years old. I'm looking into this as something new that could last longer. It's bad enough replacing the car battery every three years, replacing the jump starter also gets expensive.
These devices can only help if your battery is partially dead because it takes power from the battery. Worst case scenario is your battery is completely dead and this type will not work. The lithium battery chargers will.
True, though If car batteries go completely dead your probably going to have to replace the car battery
buy both
So... I don't understand, the battery charges the car or vice-versa? 🤔
Why does the battery keeps charging after connecting to the car's battery, considering that this one is dead/empty?
it's real and it works - don't ask me how
Well, there are a lot of situations (we saw it in the video) where the battery is NOT DEAD, but just doesn't have enough voltage to make sparks in the ignition, or enough power to turn over the starter. This seems like it can save up enough charge for a few seconds of starting excitement, kind of an emergency thing. It might be something like a "charge pump" where the capacitors are charged one at a time, or in pairs or whatever, and then used all together. So it's putting the power you DO HAVE (there has to be some!) in a different format. I think an analogy might be where you move something with a long lever or pry bar.
cool
Thanks mate
can it be used to keep the computer live while you replace the battery with a new one?
not sure - I would buy a regular one if you need to do that
2 adverts, one for sprouts ? What's that got to do with a flat battery ?
sprouts help out in any situation
Hi, how do you recharge these battery packs??
They don't store a charge long term.
When you need to use it, it'll charge from what's left of your battery. Or you can charge it from someone else's battery, and then put it onto your car.
Why has no one done a review of the new hydroshot yet lol. Jsut you. I always find it funny how people will buy the cheapest version of something and be like this sucks 😂😂😂😂 yeah.. U paid for he cheapest one. The first version was clearly a trial run.. Like every other manufactur does. I think they're amazing.as for this u should do a comparison for a few different brands
Yeah, I have considered doing a head-to-head. Maybe in the spring
what is a Hydroshot?
@@pastoryoda2789 its a power cleaner thats got a line draw and battery powered.
Badically a power washer at lower pressure 300-725 psi. Theyre the same thing but being how the power diffrence they call them power cleaners.
@@AverageReviewsYT nice 👍
Wait what!? So did you still need a new battery after that?
Nope - all set!
@@Kitearmy take my money!
@@2snipe1 I will have to get it back from the ice cream truck
Good video.well done. But just to let everyone know, the car battery has to have at least 50% charge. It will not start with a totally dead battery.
That is a great point -thanks
You're Welcome!@@Kitearmy
"Having a charged battery in your car during hot and cold temperatures, that sounds dangerous to me."
The ones that start every ICE powered car in America seem to be doing fine.
Sure - America is doiong fine but not the person who has the battery blow up in their car
@@bsnyder4912 Have you ever seen shipping boxes that have special labels because the package contains batteries? Makes you wonder why that is
@@bsnyder4912 Learn the difference between lithium batteries and lead acid ones. You should get to the point.
Have tried to purchase this item many times and this item is out of stock each time ??????
Yeah - not sure if it is a supply chain issue
I still prefer lithium ion jump packs, especially the ones between 18,000 Mah and 32,000 Mah. They can jump start any car and work as a battery bank.
I agree - this is a bit of a novelty
@@Kitearmy project farm did a great comparison on these
@@TheCamaro5 He does a great job
I just ordered the Autowit SuperCap 2 from amazon. The reason I didn't get a lithium ion jump start device is you have to make sure you keep them charged. Also, lithium ion batteries in a hot car do not mix. Could be dangerous. I also ordered a Autool BT-460 battery tester. It tests battery health, starter, charging system and max load. Between these two items, I've got things covered!
@@Dazlidorne You should be good to go for sure
What’s the lowest voltage it will charge at?
probably about 6v
@@Kitearmy Could you charge it with a 9 volt smoke alarm battery or a set of 8 AAs?
👍👍👍🙂🤝
Thanks mate
Party of one😅😅
Don't worry mate....their is always room for you in the small party bus
WE KNOW ITS HERE!!!!!!!!!!!!!!!!!
mines arriving today

it works as long as the battery has 4 volts. Thats what someone said.
I would say that is about right
Yes but if your car die on the road and have to wait a few mins or more to start that's not good.
True
But if car dies on the road while driving thats charging system, not battery only. A jumper box wont help you in such situation.
I want to order it but I can’t find the link?
Amazon AI block some people from buying
It will not start a car with a dead battery i.e. if you left your headlights on. You need some juice in it to start the car
Right - that is the limit
@user name I tested it on a battery measuring about 4volts - would not start
@@Kitearmy i heard that it comes with a cigarette port charger, which if someone is around you can charge the Supercap and it has the necessary juice to start the car. That is, if there is someone around for you to charge it. I have a NOCO GB and it still wouldn't start a car battery measuring 4 volts. At that low voltage, you just need a new battery or something is really wrong with the charging system.
@@emmanuelmatos8942 True - sometimes you need a new battery
For those saying it won't work on a completely dead battery - you need a new battery, go buy one.
that is the truth
Wow. Mate looks like a Ford van to me it that's an awful funny looking car.
It's a party buss
There are DEFINITELY chemicals and chemistry in supercapacitors. They are only "solid state" in the most general and vague sense.
I believe they are considered solid state - no?
Why do cars not have a supercapacitor built in to them. So stupid.
it would cost $2
2nd
Ur first the bot don't count
Right - Russian bot wins
You got this free I'm sure , do it on dead battery . You can charge it separately and test on dead bat, It won't work
Do you think I would really spend all this time making a video and putting on my platform because they sent me a $150 product? I stand by this video and no jumper will start a dead dead battery
@@Kitearmy yeah I do think you would do it for free stuff. No jumper will start a dead dead battery? Really? Wow your not a mechanic, that's the dumbest thing I have ever heard
I’ll make it simple for you. If jumpers could bring back dead dead batteries they would not sell new batteries in the store and you would never have to replace them.
@@Kitearmy who said bring back a dead battery? You said jump a dead battery and yes jumper boxes can jump a totally dead battery. Capacitor type can not, that's the point, even if you pre charge it. that's the test I wanted to see. Cables off battery and connected to precharged autowit
@@chadw6776 According to your first comment, you "know" that it will not work. Sounds like your mind is already made up.
if the battery is completely dead , wtf good is it ??? r u serious ????
most new cars will not run the battery totally dead
I have yet to run.on COMPLETELY dead
@@5065ca right
It's not magical it's super capacitors.
they are magical
not a full review...you didnt talk about how to start a totally dead battery with it.... boo
next year mate
There are plenty of these on the market these days, I bought one over five years ago when they were still not available in the US - had to order from China.
FYI: Why do you have to scream?!? The louder - and more pushy - you are, the less confidence you inspire.
I don't care about inspiring confidence - not a salesman mate
@@Kitearmy The question remains: Why do you have to scream?!?
