Powerful and Super Handy Jump Starter

The LOKITHOR JA302 is an excellent all-in-one tool to keep in your car. It jump-started my vehicle quickly and effortlessly, even with a low battery. The 2500A power feels more than enough, and it’s reassuring to know it can handle larger gas and diesel engines. The built-in air compressor is a huge bonus. The digital screen is clear and easy to use, and the tire inflates fast up to 150 PSI. I also like how compact and solid the unit feels for something this powerful. Battery life is impressive, with a long standby time, so you don’t have to worry about constant recharging. Overall, this is a reliable, well-built, and extremely useful device—definitely worth a 5-star rating. Read more

Perfect combo for car transport – best jump starter we’ve owned

The media could not be loaded. My husband transports cars for a living – he picks up vehicles from dealers and private owners almost every day – so a reliable jump starter with an air compressor is a must for us. In the last year we went through 3 different booster/air compressor units from other brands, and this one is by far the best. The LOKITHOR JA302 has strong power, starts cars quickly, and hasn’t let us down even with bigger engines. The built-in 150 PSI air compressor is very handy on the road, and the digital screen makes it easy to see pressure and battery status. It’s compact, easy to carry, and feels well made. Right now my husband uses it all the time during his deliveries and we’re both very happy with it. Highly recommend, especially if you work with cars and need something you can really rely on.

Compact Jump Starter

This is a very easy to haul around and have access to a car battery charger, air compressor, USB-A Charge port and LED Light due to its sleek size. I have a Maverick and this fits in the storage space under the back bench seat. This jump starter includes a USB-A to USB-C cable to charge it up. An accessory kit included contains the jumper cables (which can only be plugged one way to avoid polarity issues), an inflator hose and adapters for the hose to assist with airing up balls, mattresses, etc. It does perform well considering its compact size. It is not the equivalent of a heavy duty battery charger nor air compressor. Its use is to provide assistance for a remote car issue with a battery or tire. This is why its size really comes into play. I can always have it with my when driving my truck around. If I or someone elsa has issues, I have the tools already with me. Read more

No sure what’s going on

Just for the sake of it I deflated one tire on a 2024 Nissan pathfinder my wife 2014 Mazda 6 and 2021 Ram work truck. This thing works great on the Nissan but not on the other two. I get a 330 error that the pressure in the tire is correct but in reality was under 20 psi. Not sure if the tire pressure sensor is interfering with the other two but I really bought it for the Nissan so Il keep it. Just curious if someone has an answer on what will do that. Read more

Never be without, either to jumpstart or fill a tire

Love this so much I've been gifting them for two years now. I have one in each vehicle after having battery trouble repeatedly with one vehicle (turns out it was a case of a bad batch of batteries at the dealer), nonetheless, we were stranded more than once by a dead battery within a short amount of time so I vowed never again. This is easy to use after you charge it up to full capacity. Started two cars without hesitation nor a charge in between. Rescued us and then a neighbor. Compact enough to fit in the trunk or boot and not be an issue. And it has a tire pumper upper too! Well worth the $ Read more

Stopped working. No support.

Stopped working after very little use. No help. The device is very clean (even have the LOKITHOR case), but it reads random pressure numbers, such as 183 PSI with no hose attached. Read more

Must have for vehicle!

Hands down one of the best ones that I ever owned. This thing helped me out in so much trouble. I recommended so much that I even bought one more for other car. The tire flat works perfect with no issues and I love that you can attach and detach the cables for the battery. Read more
