This is great addition to your workshop

I have just bought one of these and they are astonishing. The battery on my 4.2 V8 S4 was completely flat and this great gadget started it straight up. https://www.youtube.com/watch?v=q7xWhyr-dDI
What is really remarkable is why the very thin leads don't get hot.

Would this work on a diesel engine battery? I've recently had trouble with a bettery on my FIAT Ducato motorhome. I ended up buying a new battery which is working fine. But this looks quite impressive.
A battery is a battery its capacity may be big or small but typically a 2.0l petrol will have a similar rated batter to say a 2.0l diesel so typically its just its capacity. regarding (Its amp hour rating)http://www.ctek.com/gb/en Ctek do a good range and
Halfords do a nice charger as well

The origional poster, well regarding thin wires there could not have been much wrong with your battery. Doesn't matter how good the charger is if you tried using 50-60 ampd down those leads you would have to have called the fire brigade

at 7.2 amps I don't think it would get hot http://www.geniuschargers.com/G7200What is really remarkable is why the very thin leads don't get hot.

at 400 amps http://www.geniuschargers.com/Boost/ that product will kick start your car
Edited to say its the appliance of Science Volts = Amps/Resistance (better known as Ohms Law)

Yes, I imagine it would one of the tests they did is place a 2010 Chevy Truck, 6 ltr V8 in -30 conditions, take the battery out of the vehicle and use the booster to start it, it started straight up.I've recently had trouble with a bettery on my FIAT Ducato motorhome.

The original post showed an image for a G7200 Chargerlooking at the G30 there is nothing magical about it, its a battery, regarding the cables not getting hot is due o the cross sectional area and the length of the cable so a 400amp battery with cables about 0.2 M long is 10 mm2 if the cable was 1 M long it would be 35mm2
I have one of these old fashioned things http://www.halfords.com/motoring-travel/tools-diy/...
and they also do a ring lithium pack http://www.halfords.com/motoring-travel/tools-diy/...
All the cables will be rated to the length supplied.
So maybe not quite so amazing other than the manufacture using appropriate length cables

Sensible comments as always toaster. The battery in it has a capacity of 2150mAh and yet it can start a 6.0L engine. This may be nothing to you, but to us mortals (who cannot start a car with a AAA battery and some ninja tricks), it's pretty cool.

So I suspect you must be clicking on different links, the order of magnitude is wrong it would take much more power to crank an engine to a sufficient speed to start the engine.
The spec of the G30 is
Peak Current Rating: 400A
Operating Temperature:-30°C (-22ºF) to +50°C(122ºF)
Micro USB (Input): 5V, 2.1A
USB (Output): 5V, 2.1A
Housing Protection: IP65 (w/Ports Closed)
Dimensions (L x W x H): 6.7 x 3.2 x 1.7 Inches
Weight: 1lb (2.1lb w/clamps)

It varies you have to look at the rating of the starter Motor http://products.bosch-mobility-solutions.com/media... you will see between 1KW and 2.5 KW The Caterham K series was 1.5 KWLooking at the example video, the unit is acting as a booster for the main battery, not a replacement. The instructions tell you to connect it to the battery for 30 seconds before cranking - assuming a shortish cranking time of 5 secs, you can get 6x the Ah into the battery that the unit on its own is capable of delivering. I know from my r/c raving days that you can exhaust a 2000mAh Nicad battery in under 5 mins, which equates to a sustained current of 12A (and makes the batteries very hot!). The unit is substantially bigger than a r/c unit, so it should have batteries capable of delivering a bigger punch than C cells.
If the starter is 1.5Kw, it will consume 125A, with a higher initial peak needed to get the whole lot turning.
Conclusion: it probably can't start a car on its own, but it will be able to boost a depleted battery enough to allow the engine to catch.
