First, we will look at the most compact car jump starters available today. Jump starters used to be bulky and weighed the same as the battery. Now they are almost as small as a smartphone and have better batteries.
Best Lithium Ion Jump Starter
Best Portable Battery Booster: NOCO Genius Boost Pro
The NOCO Genius Boost Pro is a lithium ion jump starter with four models: 400 Amp, 1000 Amp 2000 Amp and 4000 Amp. The 4oo amp model will boost a small car while the 4000 model will have enough juice to boost a diesel truck.
This battery booster has reverse polarity protection which tells you if the cables are hooked up wrong. If the error LED lights up just reverse the clamps and boost.
The NOCO has a 12V fast and a slower USB port to charge the unit. There is also a 12V adapter and a single USB port to charge your electronics.
Charging the NOCO is done with a 12-volt AUX plug in the vehicle. This method takes 2-3 hours to fully charge the booster. You can also use a USB charger but it takes a minimum of 11 hours to charge. The NOCO Boost Pro can hold a charge for up to one year according to the manufacturer.¹
The Genius Pro is able to charge your USB and 12-volt devices as well.
The built-in LED flashlight is nice for lighting up under the hood when boosting. The voltmeter feature is good for troubleshooting dead batteries quickly.
This model of battery booster is the best for keeping in the vehicle for emergencies and takes up almost no space.
The NOCO Genius Boost Pro has a one-year limited warranty.
Best Jump Starter for Diesel Trucks
Jump-N-Carry JNC770B 1700 Peak Amp Jump Starter
If you are looking for a jump starter with more power then the Jump-N-Carry JNC770B is a good choice. It has 1,700 peak amps of power and 425 cranking amps to start your diesel truck.
The front of the unit has an on/off switch, voltage display, voltage status button, LED work light and three power outlets.
The JNC770B is less portable than the NOCO Genius Boost and weights in at 23 pounds. This is due to the lead-acid battery inside the booster pack.
Charging is done by plugging an extension cord into the back of the battery booster. It will need to be charged for 24 hours when first unboxing it. The JNC770B has to be recharged every three months to keep the battery healthy. The reason is that of the chemistry inside lead-acid batteries.
The JNC770B has two built-in USB and an AUX outlet for charging electronics and an LED work light for nighttime boosting. For a bit more cash you can get the model with a built-in air compressor for emergencies.
