ToughTested Infinity 1450A Extreme Cold Jumpstarter

I've jumped my F-250 three times this winter without recharging once, and it still shows plenty of juice left. The 1450A rating isn't just marketing talk either, it cranked my buddy's 6.5L gas truck over like it was nothing.

Dead battery at -12°F and this fired my diesel up on the first try, which honestly surprised me. I've used it for four jumps now without recharging, so the 30-starts-per-charge claim seems pretty accurate.

I left my truck sitting for three weeks in a Minnesota January and it fired right up on the first push of the button. The 1450A rating isn't just marketing, it cranked my 5.3L V8 like the battery was brand new. Nice not having to flag down a stranger for a jump ever again.
