I am surprised that the NRMA would carry advertising for an item like this in "Open Road" knowing that it is impossible to deliver on the advertised claims.

I have one very similar. Bought from a motorcycle shop on Gold Coast. Guess what..it works a treat. On a recent ride away for several days it kept 3 mobile phones charged AND stared my Harley (1800cc) that had a very flat battery!!!

Have seen similar reviews and some you-tube clips...all goood..\\cheers

What have you based your "impossible to deliver" comment on?
Hopefully firsthand experience!

No, not first hand experience. The next best thing though. I searched this site:

"A lady travelling throgh had stopped to go to the loo and car would not start - battery was stuffed internally and basically no voltage when trying to crank.

A guy around at the time said "hang on - I've got a jump start kit" and brought it out of the box that was proudly advertising a "gazillion cranking amps" as all good sales advertising does.

Well if it had more than about a 7AH Sealed Lead Acid battery in the thing based on size of the box I would have been surprised and the connecting leads would have got very warm with any serious current draw.

Did it crank the car ??? I think we got an "mmmmph!!" out of it and that was it.

Like the computer speakers you get claiming they are 400 Watts in a case the size of a matchbox, they find ways of exagerating the ability of these devices badly in the marketing department - eventually you might find something like "peak power for 1 micro second" written on the box.

I think the information Oldtrack posted sums it up with the origin and poor translation of the language - the old addage "if it's seems too good to be true, it probably is".

No-one had anything good to say about them.

Shaker,

I posted my comment before this thread existed! Search under "Jump Starter". Try thread 74366 for example.

I'm glad I raised the subject because clearly the weight of opinion seems to have changed since it was last discussed.

If you flew model aeroplanes of the electric variety you would realize some battery technologies have come a long way from what you know of.
Although small, the model batteries will power extremely hightech motors which can demand very high currents.
Just a little glider can have a battery which delivers 70 amps to it's motor. 40 amps is chicken feed.

So similar technology is now used for other purposes, expensive but effective in many cases.

High energy density in some packages!

Ross,

I've been using a model helicopter lithium battery as my iPad back up battery for over a year, and have been impressed by the power to weight ratio. But as for cranking a diesel engine?

Some people had 7ah sealed lead acid batteries and made claims about jump starting and so do many portable packs. 900amp out of a 18ah sealed lead acid with spade terminals?

The batteries used in these new start packs are quite different and where your Lithium battery is small but ok it won't crank a car, but a bigger one will.
If around the size of a 7ah sealed acid BUT new technology it can deliver heavy current for a few times.

Getting back to models. the Power out of some of the small batteries, smaller than the jump pack has put many a aero modeller in hospital with horrible skin and flesh trauma from propellers.

The old model engines often stalled after having a chew, the electric just keeps chewing as they found out. The danger level and required awareness has gone up exponentially. All due to battery technology.

Guess what lots of car dealers, mechanics and some NRMA bods are using to jumpstart cars these days, they are considerably cheaper on ebay too.
We used one to crank over a 6.5 litre chev diesel on a cold morning the other week, the TWO N70's couldn't crank it fast enough, one N70 and the little jumpstarter did the job!

We have car transport companies drop new cars off to use with flat batteries and thats all they use...... A little box 3 inches X 3 inches, they say they get up to 10 jump starts no problems.

When the first came out I was sceptical about them but my views have changed.

Wow, who'd have thought !
I must admit, I felt a bit like Bob in his post, but may have to rethink that.

Based my belief on using a 900amp jump pack from Supercheap (size of say half a battery) for running a PDR led light and glue gun, and I'd be lucky to get an hour out of that (it's new, and kept fully charged).

When using this for jump starting they reckon connect, leave like that for 5 mins, start vehicle, then it will need a charge again !

Hi

A link to the product is provided in the OP's opening post - click on the word "this". It is underlined indicating that it is a link.

Cheers
