The Schumacher SL1674, 4-in-1, 1500 Amp 12 Volt Lithium Jump Starter and Portable Power Pack is a reliable companion for any roadside emergency, offering robust power and unmatched convenience. With a 1500 peak Amp engine start, the Schumacher SL1674 can effortlessly jump start up to 8.0L gas and 4.5L diesel engines. The smart jumper cable assembly features an override button for jump starting low-voltage batteries, a capability that many other lithium jump starters lack. Plus, its Pre-Boost and Pre-Heating technologies provide added assurance by pre-charging deeply discharged batteries and warming batteries in cold temperatures. Perfect for jump starting a variety of engines, it also serves as a portable power pack to keep your devices charged on the go. A patented 10 watt wireless charging pad offers convenient wireless charging for your devices, and 3 Amp USB-A and USB-C ports deliver fast charging to your mobile devices, keeping you connected on the go. Despite its compact size, which fits easily in your glove box or center console, the SL1674 is packed with innovative features, including a built-in three-mode LED light with flashlight, SOS, and strobe settings for emergencies and enhanced roadside visibility and an IP65 water- and dust-resistance rating. Schumacher also prioritizes safety, and the SL1674 includes reverse polarity protection and overload protection for worry-free operation.
