The stars speak of…
Opinions about this product were divided in such a proportion among the buyers.
did a jump start on a 6 cylinder Jeep with a stone dead battery. Started in about 3 seconds! amazing how something this small can do such a big job. Also used the compressor to air up all my RV tires (5) from 30lbs to 50lbs (the spare was down to 14lbs and I air it up to 40lbs). It took all the charge from it BUT it did all of the tires and had one battery bar left. it took approximately 3-4 hours to recharge it. All in all I believe this is a good product and you wont be sorry. That said, I only used it those 2 times so I cant really say how it will perform with many uses. That said, if you have to continuedly use this, you might consider getting something bigger or fix your problem.
The flashlight is very powerful and lasts a long time. The car starter also works well, but it drains the battery very quickly. You can probably get 2-3 jump starts out of it.

Will not jump start a car or a riding lawn mower
Will not jump start a car will not jump start my riding lawn mower air compressor works good it’s about the only thing it’s worth the crap on it it’s air compressor but jumping off a vehicle or a lawn mower it will not boost it it will not crank it I made a bad choice buying this item I do not recommend it
Terri K –
I purchased 2 of them and neither one worked.
It is an impressive looking unit with a strong flashlight. I followed the instructions that came with the unit and watched videos online to make sure I was using the product correctly. I set it up to pump up a low tire, 28psI, to go up to 35psi. The unit never showed the current psi, then I activated it and it pumped for 1 second and quit. I tried several times with the same result. Thinking maybe I had purchased a lemon, I decided to try the 2nd one I bought for my wife. I got the exact same result. Not sure I trust it to jump a car, but the main reason I bought it was to keep my tires (car and bike) pumped up. Its a lot of money to spend for a flashlight.

Keeps throwing error – too late to return, waste of money
Used once when new, worked fine. Next time I needed it, it threw an error code 430 and was useless. Over the course of a couple months tried it a couple times in different situations – always error code 430 when trying to jump a battery. Ended using it as an air compressor. After running the battery down, recharged it and it worked fine once again! Then error 430 returned. Will not jump, can not rely on it. It is either an expensive air compressor, or a paper weight. I would avoid.
Amazon Customer –
Does not inflate tires shows error 330
I think I’ve used this only for jumper cables up until this point, but I have attempted to pump aor into my deflating tire numerous times and this device refuses to function. It says that it has an error code of 330, and when I try to troubleshoot it or check how to fix it on the product website, it simply says to reset the tire psi… This does not work. In fact, my psi should be at 38 but is at 28 and the reading of PSI level indicates 105. I attempted to reach out to the company and they did not respond. At this point I feel like I wasted $100 and now on top of that have to find a place that has an air pressure pump so mine doesn’t go flat. I’m also outside of the return window now. What a waste.

It really works!!
I bought this primarily as a “jump starter”. I have used it to start vehicles multiple times without having to recharge. Recently I had an opportunity to try it as a tire inflator. Much to my surprise, it pumped up tire from flat to 32 pounds of pressure. I did not expect this small unit to perform as well as it did. I rarely write reviews or recommend a product, but I have to with this LOKITHOR JA300 Jump Starter.
Kent Sisson –
Compact and Reliable
I really like the ompact size. Can easily store under the seat of my pickup. Seems to hold a full charge for an extended period of time. Have used it on 3 occasions to jump start vehicles. Workee with no issues each time. The error code diplay is convenient. Let’s you know if you have a bad connection or an over amperage issue. Air compressor feature works well too.
