Hi has anyone tried and found a good micro jump start. I bought one for up to 2.5l and it won't start anything, the company then gave me a bigger version and it won't start my 1275 midget so they sent me their biggest version for up to 7l and it still won't start my midget v disappointed.

Was it chinese plastic rubbish ?

 

How can anything that USB charges for a few hours start a car ???

 

Save your money and buy a decent battery.

 

What sort was it ?  Then no-one else wastes their money

I have a Cobra Jumpack .... and yes it does work.

I've been told the Draper ones are pretty good, but I think they're circa £130.

They usually (claim) to have about a 10Ah battery, but have properly weenie jump leads that clearly can't flow big current.

 

I always assumed you connected them to the battery, left them for several minutes for some charge to pass between the two and then attempted a start???

No, you connect the leads, press the power button on the pack and start the car. The cranking will draw the current from the power pack and because the leads are relatively skinny there's a limit to how long the car should be cranked for otherwise they overheat. They're intended to be a boost to a dead battery, not something to continually crank with while you try to find other faults, if that's what's needed then you need a fully charged proper battery.

I guess if you need a 'micro jump start' caffine might be more effective as per the OP

 

and you probably need a new battery anyway

It's ARTECK 600A Peak Car Jump Starter (Up to 7.0L Gas or 6.5L Diesel) Auto Battery Booster and 18000mAh Portable External Battery Charger  - but my 1275 midget is too much for it

haha no it is actually relatively small. the measurements of mine are roughly 17*8*3 cm and weighs about 1,2KG so it's definitely smaller than a car battery.

'comes with a compass that is always pointing to North direction and that is good for your outdoor guidance especially when you're climbing'
