RAVPower 1000A Jump Starter | $50 | Amazon | Promo code KINJA143

Car jump starting batteries are nothing new, but this RAVPower model is more powerful than most at 1000A, and it’s a fantastic deal at $50. This has enough juice to start a 7L engine, but is still small enough to fit in your glove box. And of course, it’ll also charge your phone in a pinch.
