Highly Versatile The LOKITHOR JA300 is praised for its multifaceted utility. Users like Jerry R and Amazon Customer highlight how it has come to their rescue multiple times, whether it’s jump-starting a dead battery or inflating tires. Jerry R even mentions that it worked perfectly on three separate occasions within two weeks, saying, “Buy one with ZERO regret.”
Compact and Powerful Many users are amazed by how much power this small unit packs. Bryan S. Ackerman notes, “It’s small, super easy to use and has saved us numerous times now.” Loren Irons shares a similar sentiment, stating that it can even jump-start a large Nissan 2500 Conversion van and still performs well in other tasks.
Excellent Customer Service The customer service for this product has received commendations. Amazon Customer shares a positive experience of how the company promptly replaced a faulty unit, stating, “Very happy with this product. It is well worth the price.” This highlights the manufacturer’s commitment to customer satisfaction.
Charging Issues Some users have found the charging process confusing and time-consuming. Nicholas K. points out that the unit takes days to fully charge and doesn’t clearly indicate when it’s fully charged. This can be frustrating for users who need the device ready at a moment’s notice.
Inconsistent Performance There are concerns about the product’s reliability. Tenaj Syah had a particularly bad experience, noting that the tire inflator stopped working after a few uses and missed the return date. Similarly, Corey mentions that the unit failed when needed the most, becoming nothing more than a paperweight.
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.

Iffy Product
Charged it, and after reading the instructions I thought it would be a cake walk. I kept trying to use it I kept getting an error message. I followed the instructions, and still it wouldn’t work. The pumps works for about 7 seconds then ERROR.

Missing parts
Just ordered 2 of these based on reviews. One of them came as expected. The other one is completely missing the bag with the air hose, jumper cables and small parts.

Finally had to use and did not work
I finally had to use this and it did not charge the battery of the car so I then so if this is broken what else so I tried to use the compression option to put air into my car tires and guest what did not work so now it’s only used as an emergency phone charger. Terrible product do not buy if you do make sure everything works on it. Seems like it’s too late for me to send it back.

Doesn’t work anymore
It was good while it lasted. It stopped working in less than 2 years of owning.
Kevin A. –
Overrated
Sometimes tells you the psi on the tire sometimes it doesn’t or it’ll claim low psis like 13 and your tire isn’t flat… I’ll keep it but it’s over priced and inaccurate.
Will –
Fantastic Device!
I’ve had this jumper/air compressor for about a year now, and I’ve used about 5 times to jump car, and about 6 times to inflate my tires. Each time it didn’t fail me for the task I needed it to do. The battery charges really fast and lasts a really long time. Years ago I had a jumper:/conoressor, but it was four times the size of this unit, and weighed more than 39 pounds. So finding this device was a godsend. I’d highly recommend anyone looking for a booster, to check out this unit.
Paul V. –
it works but it doesnt !
so I finally went to use this to pump air it worked for a second and stopped or gave an error code it wont pump to a set psi or let you know it has been set its constantly flashes different psi pressures after it told you the first time what it is example tire goes low to 26psi I want to pump it to 34 psi it works for a second and stops and then flashes 30 psi or some random psi number without pumping the tire it’s useless and the directions print is so small hard to read and lengthy not sure if I’m doing something wrong or if there’s something wrong with it but im pist just go to an air machine and buy air which I was sick of everytime the weather changes why I bought this lousy product I don’t dare find out that it won’t jump a car when I need that but the air function sucks and is useless save you money folks cause this will be useless when you need it months or years later I’m tossing it in the trash $$$$ down the drain

Pressure Transducer Failed
After less than a year… I really love this unit but just last week, I was airing up my right rear tire on my car. I set the pressure and walked away from it thinking I could trust it to shut off automatically once the set pressure was reached. A few minutes later, I walked out of my workshop and saw that it was still cranking and the pressure read 0psi. 0opsie. I grabbed an analog pressure gauge and my tire was at 55 psi. Max pressure on the tire is 44. I let air out and got it down to about 38. I’m just really glad I caught that in time and am aware of the issue now. I still use it but have to babysit and check pressure manually like the days of old 😒

DON’T Buy!!
I bought LOKITHOR JA300 in October 16, 2023. I Used it no more than 2 times. Now it can only do ONE Jump start before the battery goes completely flat. If want want collect e-waste buy this, else buy something else.
Excelente muy amable persona –
Producto malo
No sirve, se supone que lo quieres para una emergencia y lo cargas y a los pocos días se descarga solo y sin usarlo, lo voy a regresar es una decepción yo lo quería para usarlo en remplazo de los cables tradicionales pero se descargan y los tradicionales no
Jerry –
Can’t find the claimed UL approval
Since this product is powered by a lithium ion battery, I specifically selected one that showed UL approval. I received the jump stater/compressor and it looks good but had no UL marking on the case. I went to the UL site and they have no record of this product, manufacturer or design group having UL approval. The vendor has not supplied the requested approval after multiple requests. I am returning it, and searching for a truly UL approved product.

My second LOKITHOR JA300 for my truck
This is the second LOKITHOR JA300 that I have bought. You think you will never need a second one until your battery dies in a parking lot. Then you remember the other is in your wife’s car, miles away. While waiting for the roadside assistance claim, I just searched for my previous purchase and reordered the JA300 since I already know how it works and it has saved me many times. I noticed that in the new purchase, the jumping cables are lighter and easier to store. Easy to store below your seat or small compartment. I recently learned that you can use it as a power bank as well to charge the phone (love it). In conclusion, you should have one of these on each car at home. I will save your day.

Finally needed
After finally needing to use this thing I open it up and find it has absolutely zero attachments with it, just the box.
Amazon Customer –
Jumps start works great pump sucks
This box does an awesome job jumping cars/trucks. Where it isn’t good is the pump. It reads way off. Bire tire with no air set it for 33 psi it runs for 1 sec and shuts off. Had to set target psi above 110 psi to get it to run long enough to air tire.

Doesn’t work after a year
Bought mine in February 2023 and didn’t use it for about 6months and when I took it back up to charge it, the forth bar on the battery light keep flashing and never complete charging. The battery cells are not retaining the charge.

Pretty good car jump starter
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.
Jerry R –
Five Stars?? NOT ENOUGH!!! I’d put TEN!
Fantastic!! Bought one about a year and a half ago. Have in the car, ready to go! And as luck would have it, had to use it THREE TIMES in the last 2 weeks. Twice for a dead battery, one for a flat tire. All THREE times worked PERFECTLY! My neighbor was so impressed, just had me order one for him. Buy one with ZERO regret. You will be impressed, not to mention how glad, should the need arrive.

Worth Every Penny!
I love this charger/compressor. I live in the country where nails flatten tires and the cold winters kill batteries. This starter/compressor has come in handy so many times. We had storms, and power outtages, which I used the light for and USB charger. Recently, it went bad so I contacted the company to see if they could help me fix it. They asked me to send them a video of the problem. The next day they got back to me and asked what my address was. A week later a new Lokithor came in the mail. Very happy with this product. It is well worth the price.

This unit is amazing and the price is right. I really love it. Thanks
Bo G. –
start the car
The jumper comes with just 12 inches long cable. I do not imagine how a person can reach the car ignition to start the car while holding the charger in hand. Placing it on the ground in front of any car (even a small one) is imposible. The instructions do not specify if the charger is in full charge at the time of receiving the package. Lack of explanation if the moving green bars means that the battery is charged in full. Lack of printed manufacturing information where their location is, phone number or how to contact them. I did not yet try other features of this battery charger.

Inflater topped working after a few uses
Now I’ve just got a jump starter and Murphy’s law, I only need the tire inflater at a time when it was important … and I can’t return it as only just found out it doesn’t work and missed the return date. I got a lemon. Let’s see if the company responds to my review and does the right thing. I’ll keep you posted.

Good but air chuck a tough fit
A decent product but the attachment for tires is hard to engage so would not inflate. Took me much hassling and eventually had to spray with a lubricant to get it to work at all.

Doesn’t work when you need it
Bought this just in case I got a flat on the side of the road. Well it just happened and when I needed it, it threw up an error code the first time I try to use it. Fully charged and now just a paper weight
