This little battery, the size of a portable hard drive is shown jumping 7 cars,one after the other in a car yard that have their car battery removed. It has a USB port and a three branch lead to charge multiiple electronic devices, a torch and the battery clamp attachment and you can recharge the unit from a cigarette lighter socket. It might be a good replacement for electronic dual battery systems that can be expensive and bulky wiring. It would suit me perfectly as i have my two batteries hooked up in parallel to give my thirsty Fridge good capacity. Spree TV channel 15 in Sydney are pushing it, worth a look in my opinion. A mate of mine tells me they are US$130, not sure of the Australian price. regards, Michael

Michael, Don't get too excited about this device just yet.

The 'MiniMax' is but one of a number of similar devices at similar prices.
It has a lithium cobalt battery rated at 200 CCA which should be capable of cranking a small petrol-engined car, but probably not a large diesel.
A car in good condition should start within 0.5 seconds of cranking which represents a battery discharge of only 0.04 Ampere Hours. I am unable to determine the Ampere Hour rating of the MiniMax but I would expect it to be around 1.0 ah, maybe sufficient capacity to crank 7 cars. I would also expect that the 7 cars you refer to probably had their engines warmed-up before the effort!

What I am leading to is that it does not take a lot of energy to fire-up an engine, or even 7 of them, just a lot of amps for a very short time. The battery capacity to keep a fridge running for a few hours of overnight camping is in the order of 25 to 50 ampere hours, a lot more than the 0.04 ah to crank a car.

So don't throw away your auxiliary deep-cycle lead-acid batteries just yet.
Cheers

Hi Allan,

I dont buy anything without looking closely at what others say about it. It does seems crazy to work as it's advertised. I agree with all you mentioned about tricks to make it perform well , they also did start a 6 litre V8 truck and says it works in cold conditions. In regard to my comment about my fridge, i actually meant that my batteries are in parallel and therefore I dont have a solenoid type system so if my batteries are flattened, that unit could get me out of trouble if it works as advertised. It would be nice to see comments from others that have purchased one. regards, Michael

Ah yes Michael, it could well serve as a back-up cranking source if you drew-down your battery bank too far. I do wonder if that was a petrol or diesel V8 truck? Diesels do require a good deal more cranking effort.

I also had a look at these today. Uniden and Bainbridge Technology have them but advise < 3ltr diesels and < 5ltr petrol on one site. No good for a big 4X4 diesel.

It was a Yankee ad, Petrol no doubt. Still an interesting concept and as battery technology gets better, who knows what is possible. Michael

Would't the flat battery bank suck the juice before you had a chance to start the car?

No Honky, with the output voltage of the MiniMax being 12v, little current would flow to the installed battery. It would need to be of the order of 14v or more. The full power of the MiniMax would be available to the starter motor.

" may not start some diesels ".......or petrol engines that aren't warm and not long turned off ?

If I had a manual 4wd, I think parking it on a slope would be better value.

Or have a batt isolator that makes sure the starting battery never goes flat !

This mob don't also sell Hiclones do they ??

Good one Gronk. They would be fine for a small four cylinder petrol but can't see them being any good for anything else except charging your phone.

The add is interesting, I guess the truth is in the feedback from those who have tried them. Years ago i woke to a flat battery at the Warrambungles, fairly flat road around the camp area, a slight push, barely moving and cold engine, and the 4.2TD started easily. I guess the manual box and old technology helps!! Michael.

I ve had one for over 2 years now. It has had to start my 1.9 litre v twin high compression Harley twice when I had left an auxillary item on. Saved the day for me, that's for sure Have seen them start a 150 four stroke Yamaha outboard as well. Could probably start a 3.o litre diesel but I couldn,t see it starting any of the big 6 or 8 cylinder motors. Could be wrong because battery technology is forever changing and pretty quickly too.

Fact is, these physically small lithium cobalt batteries pack a wallop and demonstrably easily start a car. But a large diesel may present a challenge. Packs to suit them will undoubtedly become available.

I have one which has been used once in anger. Started a 3 litre diesel Prado easy as pie.
I was quite surprised at how well it worked.

There are plenty of these products on the market and they generally work - most cannot provide the CCA directly to fire an engine but most provide enough overall energy into the battery after being connected for a short time might be less than 1 Ah but the CCAs might be up there.

All reports are that these devices do work to fire up engines that are in good condition and the batteries are not dead.

There are a few threads on similar products on this forum.

I have a Smart Start Charger 600 Amp Power Pack and Jump Starter , 4 litre diesel and 7 litre diesel [ SSC06 ] paid $179.00 and delivered to door . I have jump started V8 petrol cruiser twice , 6cyl petrol Jeep twice and 4.2 turbo diesel Cruiser once over a period off 2 weeks and had not recharged unit , it has 240 and 12 volt chargers supplied and you can charge all sorts of phones/ipads/media units with a range of adaptors supplied , in a neat plastic container. I have since replaced the offending starting batteries in those relevant vehicles . There are more powerful units available if required ,do a bit of research

Mine is from Repco and works a treat on the following "used in anger" to help others

A Holden Commodore V6
A Jeep Cherokee diesel
Couple of smaller 4cyl passengers
Our 3.0L turbo diesel Hilux

Didn't work on my John Deer tractor the other day damn it !....but I didn't expect it to......so took me 1/2 hour to shift some stuff because the jumper leads to the Positive off another vehicle was short by about 2 " !!!

As for the Op stating showing starting vehicles with no batteries.........not sure of that's clever because the instructions clearly state to remove the device ASAP after starting

So in summary yes they work or mine does...horses for courses as they say........but I wouldn't rely on it for bigger diesel vehicles.....I do take it out on our boat (90HP two stroke) just in case

Friend I was travelling with used his 600a unit to start a 7.3L diesel F truck from cold, no problem.
Was at Sandstone CP, outside temp was low single figures (5C) and the F truck had stood overnight.
Yes they work on biggish diesels, probably not on Kenny's or Mack's though.

Of all the people who have used one of these , how many have used it without the starter battery in circuit ??

Most flat batteries only need a small boost to crank an engine....I wonder how many of those batteries were dead flat ??

I have. Only a 1.3 L Starlet, but was dead flat. Had stood for 6 months unused. 2nd attempt, away it went.

Mine cost $199.00 but was over 18 months ago. Money well spent.

I have one its rated @ 13800 mAh - 600Ah l think , a mate has borrowed it atm , so l can't check .

I have only started a small Suzuki 4x4 with dead flat battery ,it fired up instantly.

Because l do a bit of Motorcycle camping , I gave it a try with my CPAP machine the other night , it was good for just over 9 hours .

Yeah well , l dunno then , like l said that is what l THINK is says on the thing , a mate has borrowed it
( fair chance I have it wrong )
I will double check when I get it back .

Anyway it did jump start the dead flat Suzuki and it did run my CPAP for over 9 hours .

I have only ever charged it on 240v , l now need to see how long it takes to charge on the bike.

There are a few on the market with 13.8 ah and 600 amp delivery specs, all with differing brand names but possibly from the same manufacturer. So Jacko's is probably one of those.
I would expect it capable to start a Suzuki and to run a CPAP for 9 hours.

As an aside..... how the hell did this "thousands" of milliamps thing start for products with several AMPS? Just another attempt by marketers to con you into thinking that their product is bigger or better than it really is?.... Snake Oil !!!!

Thanks Allan , l just re-read my original post , it was a typo , 600Ah should be 600Amps .

I know I was very sceptical of the claims , these things have been around for a few years now ,
I often looked at them and talked to ppl selling them at shows and always thought bs , snake oil
How cold something that small , start anything .

They have come down a lot in price over the last couple of years , so l bit the bullet and bought one when I saw it on for special $125 , another shop had the exact same one for $189 .

I won't be replacing my Dual Battery setup anytime soon with one , but l think for what they cost and the size , l will probably get second one to carry on the bike .

I have the Battery Fighter JPR9000M Jump Starter.

see Battery Fighter Website

It is the only jump starter I've found with cables/connectors that look like they can carry the high amperage needed to start the vehicle, the others appear to be little more than a battery bank for electronic devices with some alligator clamps added on.

There are a couple of different sizes/capacities, the 9000M is a 9ah lithium-ion battery with 810cca, they suggest it will start 6l petrol / 3.5l diesel from flat (it has a setting for really flat batteries as well as those just needing some assistance).

It comes in a pack including an ODBII connector cable, so you can plug it in to keep your electricals (clock etc) powered whilst changing your main battery over, plus the usual USB ports/lights.

It is a bit more expensive than the others though.


cheers

A update , l got my Mini Jump Starter back off the mate today . We have a old EL Falcon 4Lt petrol motor , l turned on the Head Lights , Fan and Radio , flattened the Batt dead flat , turn the key nothing .

My Jump Starter claims 13800mAh - start current 300A - peak 600A .

I started the Falcon 12 times , cranked it a few times with the head light on between starts with the Jump Pack disconnect to make sure the Batt stayed dead flat ,

The Jump Starter claims to have 30 starts before it needs charging , l stopped playing at 12 , it still showed full charge .
