Hi Guys

On the net, i see so many videos that owners jump start their cars by solely thru a power bank that we charge our mobile phones. They do it constantly up to 10 times but their cars has a small engine.

Can Power bank with 10,000-13,000 mAh or more jump start 6 cylinder 3,0 L bmw petrol engine ??

Even once starts, then charge off, it is still fine for me.

Or need more power up to 20,000 mAh version ?

Has anyone try that and recommend a brand ?

What you should be looking at before purchasing one of these are the CCA "cold cranking amps". This will tell you if it will be able to crank your car or not. Most cheap ones only crank a car that is rated at 400-500 CCA. Before you buy make sure it is at your rated battery or you will not get the car started. Also make sure it has a lithium battery. Below is an example of one that is good for 3.0L engines.

Thank you mate.

Before your message, I was in the Usa last week and could not help myself buying one at Walmart. It was the only option there on the shelf anyway. It peaks 400amp. Brand is Whistler. I knew whistler is a good Usa company. This morning my car was dead after a week or more at garage. Everything was dead and key opened the car. Thanks God it started. So it is worked out for the moment. Thank you anyway. Would be Better off buying the one at higher Amp value anyway.
