Newer cars with four-cylinder engines reduce the amount of power a jump-starter needs to supply. The small, inexpensive Scosche PBJ700-1 can start a four-cylinder, or in an emergency a six-cylinder via the boost feature.
It comes with spark-proof technology and lots of practical features, including two five-volt USB charging ports usually found in more expensive models.
The small, well-priced yet heavy duty Noco Boost Plus GB40 is a great investment. Rated at 1,000 amps, this packs the power to jump-start 6.0 L gasoline and 3.0 L diesel engines. Vehicles with diesel engines now must have selective catalyst reduction (SCR). A filter removes most of the soot from exhaust fumes, which are then treated with diesel exhaust fluid (DEF).
Although lacking a 12-volt power outlet, the GB40 comes with overload and spark-proof technology. Handy extras include a seven-mode LED flashlight and USB-A port. Relatively light at two and-a-half lbs., it’s water-resistant with rubberized shell that protects your vehicle. Oh, and it can hold its charge for up to a year. At about $145, it’s worth every penny.
Small yet powerful, the 3-1/2-lb. Avapow A58 jump starter does it all. This 4,000-amp jump starter is rated for all gas and up to 10 L diesel engines. It comes with all basic safety technology, dual USB 3.0 ports and a three-mode LED flashlight.
The A58 works on 12-volt hybrids, motorcycles, lawn mowers, boats and snowmobiles, making it an excellent choice when camping or traveling.
The 3,00o amp rated Noco Boost Pro GB150, big brother to the Noco Boost Plus GB40 featured earlier, has significantly more power to start a 9.0 L gas or 7.0 L diesel engine, as well as large truck and marine batteries not regularly used during the winter.
It comes with heavy-duty clamps that easily cut through corroded battery terminals. Basic safety features including reverse polarity protection and a built-in voltmeter. It’s expensive, but its ability to power 12-volt devices and hold a charge for up to one year make it attractive to large vehicle owners.
Small and light at 2-1/2-lbs., the 2,000 amp rated Nexpow G17 ($90) can revive up to 7.0 L gas or 6.5 L diesel engines. A safety indicator with buzzer and flashing lights alerts you if the battery you’re jumping has excessively high or low voltage, or the cables are reversed.
Useful features included an LED flashlight; USB, USB 3.0 and USB-C ports to quickly charge phones and tablets; and a powerful 12-volt/15-amp outlet. Consider this jump starter for camping and traveling.
If you’re looking for a good mix of power and features and budget isn’t a concern, then a Hulkman Alpha85S is the right choice for you. With 2,000 amps, it can start vehicles with 8.5 L gas or 6.0 L diesel engines up to 60 times without recharging. A preheat feature can start your car at minus 40 F.
The 65-watt charger with over-volt protection can recharge the jumper in 90 minutes. Abundant USB ports, a 12-volt/10-amp power outlet and LED flashlight are included. The easy-to-read 3.3-inch information screen, two-year warranty and lifetime technical support makes this jump starter a winner.
Weighing less than three pounds, the JF.Egwo ‎CS02-200 packs a lot of features into a 5-in. x 6-in. package. With a built-in air compressor and rated at 3,000 amps, this jump starter has the muscle to get a 9.0 L gas or 8.5 L diesel engine, 12-volt RV, lawn tractor or marine battery going.
The 150 pounds per square inch (psi) air compressor comes with an auto-stop feature, digital LCD pressure gauge, and an extension air hose to fill a flat tire, basketball, pool toys and air mattresses. Two USB ports and LED flashlight are handy extras.
Although the CS02-200 lacks spark and reverse polarity protection, its many features and compact size make it worth consideration.
Much bigger and costly than its lithium-ion cousins, the Clore Automotive Jump-N-Carry JNC770B Â can fire up almost all passenger and light commercial vehicles.
Used by the pros, the JNC770B can deliver 1,700 amps — exceptional cranking power to start a dead battery. It also features an automatic built-in charger, digital voltmeter, extra-long cables, dual 2.1A USB outputs and a 12-volt power outlet. Note: This product lacks spark and reverse polarity protection.
The Schumacher SJ1332, rated at 1,200 peak amps, can jump start big V-8 gas engines and up to 6.0 L diesel engines. It also comes with a host of impressive multi-use features, including a handy built-in 150-psi air compressor that can fill a flat tire, air couch, bouncy house and holiday lawn decorations.
A built-in 12-volt inverter powers two 120-volt/10-amp power supplies that can run a small LED TV or video game console, plus charge a laptop or tablet. The USB port, LED work light and digital display showing the voltage of vehicle battery being jumped come in handy. The SJ1332 also comes with reverse hook-up protection.
