MINIMAX Car Jump starter. Fits in your pocket!

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.

" 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 ??

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

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 ??

ABR Sidewinder have just advertised one of these type of Jumper Starters for AUD$125.00 See the following link for more info.

ABR New Arrival - Small Battery Jump Start Pack

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.

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 .
