Car Jump Starter Booster Charger Power Bank

Hi Rojac I think best way is to get dead battery and test one out.As I have heard they only good if some charge left in battery will not start completely dead battery.Be good if I am wrong!!

After a recent call to RAC due to a flat battery, thanks to a 'Fridge Switch', I started looking at these, haven't bought one yet but my investigations revealed not many are suitable for diesels; unfortunately, not many actually carry that warning. If you have a diesel look for one that specifically states it is suitable for diesels of a similar cubic capacity to yours.

Most of them have a disclaimer that they are no good for disel engines. Friend of mine bought one and then found that it was no good for his 6 cyl diesel.
Perhaps for 4 cyl units they might work.

Gooday,
If you wish to spend some money for this situation, just put the money you were going to spend on this Gimmick on a DECENT pair of Jumper leads, there is always someone who will come along who will give you a jump start.

Our Jumper leads are about 8-10 ft long, made from heavy duty welding cable with good solid clamps, don't buy the cheap and cheerful from Super Deals or such.
Had ours for over 40 years.

There has been a lot of discussion about them here before . I have one and deliberately flattened the battery in a 4lt EL Falcon , dead flat , started it 10 times , between each start , I disconnected the jump started , cranked the motor with the head lights on , to make sure the batt was still dead flat ,

It started instantly each time , even with the headlight switch in the on position
I stopped playing at 10 starts the jump started wasn't flat ,

The Falcon was going to the wreckers , so I wasn't worried about buggering the battery , I haven't tried it with my Dmax it's supposed to be able to start a Deisel .

I run my 12volt CPAP off it for 2 nights and have changed a phone , GoPro and Lap Top a few times off it .

I now have a second one , good thing I reckon

Battery world have a 400, 500 and 600 amp mimi starter packs. They are reputable, so you don't have to worry about whether a product off the net will do the job.

I bought one on ebay for $100, 600CCA for 3 seconds then 300CCA.
I have used it twice to jump start my 2005 V6 petrol Hilux, the first time I disconnected the battery and started the hilux with the jump pack just to test it out, the second time I used it was just the other day when i jumped in the car at the airport long term parking and the battery was totally dead due to an unresolved electrical problem. It started the hilux as if it was the main starter battery, great product for the price and size(fits in glove box). I don't know about longevity yet but in my opinion they're well worth a look. Just do some research on brands/models etc, you might have to spend more dollars on a model that will start a 4.2 diesel, not sure about that?

Slightly off topic but saw a batteryless jump starter in jaycay the other day. Uses ultracapacitors looks VERY interesting idea is that it uses tiny amount of energy left in "dead" battery to charge itself then delivers it in a big chunk to start engine. Or one looking same on youtube can charge from usb in 2 minutes or from any low current 5v or more source. Expensive though.
Was thinking you could use it and 4 aa cells to start engine
Havent tried it though
