Dead battery? No problem.

Whether you’re in your garage or miles from home, this jump box is built to deliver a reliable jump start when you need it most.

Designed for real-world use, the Schumacher SL1674 is more than just a jump starter—it’s a smart solution for modern drivers. It starts gas engines up to 8.0L and diesel engines up to 4.5L with ease, and it’s especially handy for dead battery situations that leave other chargers at a loss. With jump start override you can easily start low-voltage batteries, unlike many other jump starters. Plus, thanks to Pre-Boost and Pre-Heat Technology, the SL1674 will warm your battery in cold temperatures and pre-charge deeply discharged batteries, giving you a better shot at getting back on the road—fast.

Need to charge your phone too? The SL1674 has you covered with a 10W wireless charging pad, plus 3A USB-A and USB-C ports. Whether you’re topping off your phone or powering a GPS, this portable car jump starter doubles as a power bank that keeps your devices going strong.

Safety is built in from every angle. With reverse polarity protection, short circuit defense, and safeguards against high/low temperature, voltage spikes, and overloads, the SL1674 is engineered to protect both you and your vehicle. It also includes a built-in three-mode LED light with flashlight, SOS, and strobe settings to illuminate your surroundings when needed for safety and convenience.
