RockyRaccoon on 09/03/2013 - 08:44 ¶Really Jim. What makes you so sure that was someone from Dick Smith or MiGear?
I would really doubt if they would be trolling around Ozbargain trying to promote a clearance product. Not worth their time.

+5 votesCars don't draw 1200 or even 900 amps, and any jumper cable that claims a capacity of that much is almost certainly lying.
If you want to see how much current a car draws, just look at the "cold cranking amps" rating of your car battery, and the starter MUST draw less than that, usually substantially less. Most car batteries are in the 300-500 CCA range, with some extra-large batteries offering up to 700 CCA.
Also, the standard rule-of-thumb for current-carrying capacity is 10 amps per square millimeter of cross-sectional area. 1200 amps therefore requires a solid rod of copper with 120mm^2 cross-sectional area, which would ba a solid rod with a thickness of 12mm. Stranded copper wire would be a little thicker again, and adding insulation as well would give you a cable thickness of about 15mm.
While some cables may look almost that thick, pull back the handles on the battery clips, and you'll almost certainly see they have quite thin copper wire, maybe 6mm diameter at best, and usually quite a thick layer of insulation to make them look more impressive.
Thirdly "jump starting" a car does NOT usually draw a lot of current through the jumper cables. The purpose of jumper cables is to charge the car's own battery. One or two minutes of charging at 11A will probably be enough to start most cars with flat batteries, but leaving it for five minutes is better.
However, some faults (like a shorted cell in the battery) will mean the car can't be started without replacing the battery first. Jumper leads won't work in this situation, and if they COULD deliver 1200 Amps at 12V, i.e. 14400W of power, you would very likely have an explosion in the faulty car battery at the very least!
+2 votesJust to be picky, battery capacity ("power" as you state here) is measured in Ampere-hours, which on this item is 8Ah.
300amps specifies the amount of electrons flowing around a circuit in a given duration. Think of it as the difference between a garden house and a fire hose, you still get the same amount of water, it just takes longer.
300Amps will start any car, it will just take longer than 900Amps.

Your 500mA power source is an irrelevant example. In theory, I believe thefuzz is correct.
"The time taken to recharge any battery is dependent on the voltage and current applied. If the
recharge current or voltage is too low, then the recharge time will be relatively long; if the current or
voltage is high then the recharge time will be short."OR please check:
+1 voteIt really depends on the state of the battery, and what car it is. A 4cyl car with a depleted but not totally flat battery should be fine.
I have a 17Ah "1,000A" portable jump starter that couldn't start my 6cyl 3.0L car whose battery died when the car wasn't driven for three and a half weeks. The car battery was so flat that it was drawing all the power to recharge itself - my 3.5A Calibre charger kept blowing its 5A fuse too.
In the end I just left the portable jump starter hooked up for an hour or so to recharge the car battery, then hooked up an old car battery someone left behind in the car park and managed to get the car started.

Thanks op! Also grabbed Animagic Cassy for $10 click& collect…stock in innaloo and claremont quarter

Animagic dog is also $10 but did not check if there's stock
+1 voteI find these portable jump starters brilliant. I drive a manual too, and my car is always garaged.
For my situation, in order to get my car on to the street I have make a left turn onto the driveway, then a right onto a busy street before I can get enough momentum to roll down hill for a clutch start. If I stop to avoid a collision while entering the street, I may not be able to push the car off the gutter where the driveway meets the street.
Driving a manual does definitely give us more options, manual clutch starting isn't always practical. My situation is just an example where it's just not practical and is dangerous to attempt to do so.
Having a jump starter pack comes in extremely handy when I don't have time to trickle charge the battery.
I have the PSX2 EU model which is a different brand. It's a 400 amp unit and is enough to start a 6 cylinder engine from a totally dead battery. I paid $130 for mine at Costco.
$20 for the unit posted is definitely a bargain!

In some cases, it's possible for a manual to require a jump start. If the battery is completely flat (ie leave lights on) the engine electronics/computer won't turn on and if that happens obviously the engine won't run even when push started.
It happened to me in the past in my little Lancer, which I'd previously roll started on my own but if the ECU and dash lights don't come on there's not much hope.
I'll agree with you if your car has a carby. :)

RockyRaccoon on 10/03/2013 - 15:37 ¶Important for those of you who bought one. Make sure you recharge it for 30 Hours before first use. Even if the green light says its charged. Makes for longer lifespan
highdealer on 11/03/2013 - 09:50 ¶Either you are lying or the manager is lying, they had 3 in stock and there was 4 people proceed with click and collect, they even call me to confirm that first in first serve. I went there and saw a dude got his power station there. I was gonna get mine but decided to save a few bucks and not get it since i wont be using it much.

Just bought one for collection, Thanks BalleBalle.
