Schumacher Electric Car Battery Jump Starter

Best for: Home garages and small shops

Pros

• 1800 peak amps
• 225 cold-cranking amps
• Corrosion-proof case
• Built-in charger

Cons

• 5 pounds
• No USB ports listed

Best for: Road-trippers wanting air and AC power

Pros

• 1200 peak amps

Cons

• Heavy at 18 pounds
• Sealed lead-acid battery

The Schumacher Electric Car Battery Jump Starter and Power Station, model SJ1332, is a 6-in-1 unit: jump starter, portable power station, AC converter, air compressor, inflator/deflator and LED area light. It delivers 1200 peak amps, which Schumacher says can start 8.0L gas and 6.0L diesel engines.

Peak amps is the maximum burst of current a jump starter can release for a moment. More peak amps generally means it can handle bigger engines and colder conditions. The SJ1332 also has a 150-PSI air compressor with automatic thermal shut-off for tires, sports balls and pool floats. For power, it offers one 2A USB-A port, two 12V DC outlets and two AC outlets powered by a 200-watt continuous, 400-watt peak converter, enough for small devices. It uses a 12Ah sealed lead-acid battery, 4-gauge 24-inch cables and reverse hook-up protection, which prevents damage if the clamps go on the wrong terminals. It is UL listed.

At 18 pounds and 13 x 13 x 14 inches, it lives in a trunk or garage rather than a glovebox. It suits families who road-trip, camp or want one tool for flat tires and dead batteries. For something that fits in a glovebox, see the lithium packs below.

• Recharges in 4 hours

Cons

The Schumacher Electric 1000 Peak Amp 12V Portable Lithium Jump Starter, model SL1639, is a compact lithium-ion jump box. Schumacher rates its 1000 amps for up to 8.0L gas and 6.0L diesel engines, the same engine range as the larger SJ1332.

It doubles as a USB power bank with two ports: a 2.4A port Schumacher says charges twice as fast as standard USB and a 3A port it says charges four times faster. The LED flashlight has steady, SOS and strobe modes. Smart cables provide spark-free protection against overcurrent, short circuit, overload, overcharge and reverse hook-up. It recharges fully in four hours and is slim enough for a glove box, purse or backpack, measuring 1.53 x 3.31 x 14.18 inches.

It suits a new driver who wants simple, reliable backup in the car. If you want wireless phone charging, the SL1672 or SL1674 adds it.

Schumacher Electric Portable Car Battery Jump

Best for: Small cars and phone-heavy drivers

Pros

• 10W wireless charging pad
• USB-C and USB-A 3A ports
• Pre-boost and pre-heat
• Override mode for dead batteries

Cons

• Rated to 3.0L diesel only

The Schumacher Electric Portable Car Battery Jump Starter and Power Bank, model SL1672, is a 4-in-1: jump starter, 10W wireless charging pad, USB charger and LED light. It delivers 1000 amps for gas engines up to 6.0L and diesel up to 3.0L, and the listing says it works with standard, AGM, maintenance-free, gel, calcium, EFB and deep-cycle 12V batteries.

It has a 6400 mAh battery, a 3A USB-A port and a 3A USB-C port. Two smart features help with tricky batteries: Jump Start Override Mode lets you manually start a deeply drained battery the unit does not detect, and Pre-Boost and Pre-Heat technology adds a pre-charge and warms the battery for easier starts. It weighs 1.6 pounds.

It suits sedans, hatchbacks and small SUVs, especially for drivers who like dropping a phone on a wireless pad. For larger diesel trucks, the SL1674 or SL1652 is a better match.

The Schumacher Electric Portable Car Battery Jump Starter and Power Bank, model SL1674, is the stronger sibling of the SL1672. It delivers 1500 amps for gas engines up to 8.0L and diesel up to 4.5L, with a larger 10,000 mAh battery.

It shares the 10W wireless pad, 3A USB-A and USB-C ports, LED light and Jump Start Override Mode. The SL1674 listing does not mention Pre-Heat technology the way the SL1672’s does, so do not assume it is included. It weighs 1.7 pounds and measures 7.08 x 3.58 x 1.69 inches.

It suits owners of full-size SUVs and gas pickups who still want a glovebox-size unit. For big diesels, the SL1652 is rated higher.

The Schumacher Electric Car Battery Jump Starter and Power Station, model DSR119 ProSeries, is built for professional-style use. It delivers 1800 peak amps for 8.0L gas and 6.0L diesel engines, plus 280 cranking amps and 225 cold-cranking amps. Cold-cranking amps measure how much sustained power it can provide in freezing temperatures, a useful figure in cold climates.

It uses a high-output AGM (sealed lead-acid) battery in a corrosion-proof case with heavy-gauge cables and professional clamps. A 12V DC accessory outlet powers devices, and a built-in charger recharges it from a 120V wall outlet. It weighs 17.5 pounds. The listing does not mention USB ports.

It suits a home garage, small shop or someone maintaining several vehicles and boats. For road trips with tire inflation, the SJ1332 adds a compressor.

Best for: Big trucks and cold climates

Pros

• 2500 peak amps
• Up to 50 jump starts per charge
• Pre-heating technology
• 58 Wh power bank

Cons

• 7-8 hour USB recharge

The Schumacher SL1652 Rugged Lithium by Schumacher is the most powerful here at 2500 peak amps, rated for 10.0L gas and 8.0L diesel engines. Schumacher says it can jump start a vehicle up to 50 times on a single charge.

Pre-Heating Technology warms the battery to help starts in extreme cold, and Pre-Boost adds a pre-charge to deeply discharged batteries. As a power bank it holds 49.58 Wh and charges devices through USB power delivery, plus a 2.4A USB port. It recharges in 7 to 8 hours via USB or 4 hours with the 12V car charger, and a three-mode LED light helps under the hood. The spec table lists battery capacity in “amp hours” as 13400, which looks like a units error.

It suits big trucks, diesel owners and drivers in cold regions who want a compact pack. For a small car, the SL1639 is plenty.
