Power, versatility, and reliability in one compact unit

Meet the Schumacher SL1654, a 2250A rugged lithium jump starter that also functions as a portable power pack and an LED flashlight. Built for on-the-go versatility, it can help you start mid-size gas engines up to 10.0L and diesels up to 8.0L, with a compact footprint that fits in your trunk or under a seat.

Three ways to power up

  • Jump starter power with 2250A peak, ready for a quick engine start
  • 2.4A USB port to recharge phones, tablets, or other devices
  • Integrated LED flashlight with steady, SOS, and strobe modes

Smart features designed for confidence

  • Pre-Heat and Pre-Boost Technology warms and pre-charges deeply discharged batteries
  • Jump Start Override Mode provides manual control when automatic detection isn’t possible
  • Safety first: reverse polarity protection, short circuit protection, and temperature monitoring

Recharge is convenient: USB recharges the internal 49.58 Wh battery in about 7–8 hours, while a 12V car charger brings it back in around 4 hours when you’re on the move. The unit uses a 4-cell Lithium battery and a rugged 8-gauge jumper cable with heavy-duty clamps for durability.

Three notable advantages are highlighted by the data: faster recharge times, lighter weight, and longer shelf life than traditional AGM jump starters. It’s compatible with a wide range of vehicles, including cars, trucks, SUVs, motorcycles, ATVs, RVs, and marine batteries, making it a versatile tool for weekend warriors and daily commuters alike.

Care and usage tips: avoid storing in extreme heat and discontinue use if swelling or discharge occurs. This device is compact, portable, and ready when you need it most.
