We’ve always known MAGFAST® Extreme™ was powerful … really powerful. In fact, with our Jumpers™, it’ll jump-start a car. So, to find out exactly how powerful, we recently ran a real-life test to see how many times it could do so before it needed recharging. And to make the test as tough as possible, we used a 5.4-liter truck, not just any old 2-liter family sedan! Watch this video to see the results of the test - but prepare to be amazed because the results are truly astonishing. We were as surprised as you will be!
