Seems like an awesome product except for the battery rating of 3000mAh? Seems to be missing a zero in there or is it 3000mAh @ 12v ?
Anyone bought it today and can comment on the actual battery capacity?

Depends on the size of the car battery and how much effort it takes to start the engine. Some cars don't jump start so easily.
This will give you enough if the engine is healthy and the battery low rather than flat. I have a 20Ah USB style battery bank with a specialised high current circuit that jumps a car quite well, (it stops working to prevent the batteries exploding should you need to crank longer than 6 secs). This will be similar, but unless fully charged will not help you unless your engine is very small. At full power one or two tries will probably be about it, just depends how easily the car starts.
But remember, anything battery powered that you leave in the car you have to charge and keep charged for them to be useful on that odd occasion you might need them. Also, the 12V air pumps in these sort of things are notorious and fail in no time.
Bought one today too, seems like a newer model. Couldn't find any review based off the model number.
Anyways tried the air compressor on my Mazda 3 tyres, it overheats and shuts off quite quickly, around 4 to 8 minutes depending on how high the bar is set to. Then you'll have to let it cool down for another 10 to 15 minutes before it'll run the compressor again.
Haven't got to test the starter yet.
Overall, I'm still unsure yet if it'll have a place in the kit.
thanks for the feedback!
is the torch useful? and does the LCD pressure gauge seem reliable?
Torch is adequate, certainly enough to get jobs like changing tyre or jump starting a car in the dark.
Regarding pressure gauge accuracy, I'm yet to confirm it's reliability.
Bought one of these from Aldi. On the box and instruction manual it displays psi. On the unit it only has bar. Spoke with after sales and it's a known issue, advice was to return and get refund as they are having problems with the supplier replying to the concerns raised aka false advertising.
It would be 3Ah (3,000mAh) @ 12v. Phone batteries and phone battery packs are usually 10,000+mAh (or 10Ah) due to them only drawing 5v.
What you need to look at for a jump starter is the ability of the battery to dump voltage quickly. For a jump pack, I would be looking at the amount of amps that could be drawn off it, not what its storage (Ah) rating is.
In simple terms;
Amp hours (Ah) = how long it will last with a load on it (size of the bucket)
Amps = how fast you can suck out of it (size of the funnel your pouring into)
Volts = pressure (how fast it comes out)
