Hello,

My battery died and I had to boost it.

Someone helped me with a Motomaster booster pack (I don't know which one) and it worked.

Then I went to Canadian Tire and they tried to help me with 3 different booster pack but none was able to start my engine ! Even powerful booster pack !

I want now to buy a booster pack that is also doing battery charger and I'd like to know which model could do the job .

I've seen this good offer in Canadian Tire (89$) for a Caterpillar booster/charger . Booster power is 540 watts, so I don't know how to convert into Amps power ...

Do you know if 540 Watts could be enough to start my Chevy Van G20 (5.7L) ?
(My battery is a 800/650 Amps)

Thank you a lot !
