The Schumacher SL1672 is a compact 4-in-1 portable power pack that delivers a 1000A jump start, 10W wireless charging, USB fast-charging, and an emergency LED light in one rugged unit.

When a car, truck, motorcycle or boat battery leaves you stranded, the SL1672 combines dependable jump-start capability with modern device charging and safety features so you can get moving fast. Built around a 23.68Wh four-cell lithium battery and 1000-amp output, this unit is engineered to start gas engines up to 6.0L and diesel engines up to 3.0L. It also offers Jump Start Override plus Pre-Boost and Pre-Heat functions to help revive deeply discharged or cold batteries that other starters may not recognize.

How does the SL1672 safely jump-start a vehicle?

The SL1672 uses heavy-gauge jumper cables and integrated safety systems to deliver a reliable start while protecting you and the vehicle. Reverse polarity protection, short-circuit defense, and overload limits prevent damage during use. The unit’s Jump Start Override enables manual starts on low-voltage batteries that might otherwise be ignored.

• 1000A peak current for gas up to 6.0L / diesel up to 3.0L
• 10-gauge, 15.5-inch color-coded jumper cables for easy connection
• Reverse polarity and short-circuit protection for safe operation

What device charging options does it offer on the road?

Beyond jump-starting, the SL1672 acts as a portable power bank with a 10W wireless charging pad and two fast USB ports. Use the wireless pad for compatible phones or plug in via USB-A or USB-C (3A) for quicker top-ups. The pack recharges in about 4–5 hours via the supplied USB cable for rapid readiness.

• 10W wireless charging pad for cable-free convenience
• 3A USB-A and 3A USB-C ports for fast wired charging
• Internal 23.68Wh lithium battery supports multiple device charges

How does the built-in LED light and weather resistance help in emergencies?

The SL1672 includes a three-mode LED (steady, SOS, strobe) to illuminate work areas, signal for help, or increase visibility at night. With an IP65 dust- and water-resistance rating, it tolerates splashes and roadside conditions so you can safely operate outdoors. The light plus compact footprint makes it a handy addition to glove boxes, trunk kits, or camping gear.

• Three LED modes: steady lamp, SOS signal, strobe for emergencies

• Compact, portable design that fits in trunks and storage compartments
• Durable housing and user-friendly controls for roadside use

What maintenance and safety tips should owners follow?

To keep the SL1672 ready, store it at moderate temperatures and recharge after use. Avoid leaving the unit in extreme heat or cold and stop using it if the battery shows swelling or abnormal discharge. Follow the included manual for proper clamp connection and adhere to all safety warnings for best longevity and safe performance.

• Recharge after each major use and avoid extreme storage temperatures
• Inspect clamps and cables for wear before each use
• Do not use if battery swelling or abnormal behavior appears
