JA401 3750A Jump Starter with Air Compressor, 60W Two-Way Fast Charing, 12V Lithium Battery Starter with 150PSI Auto-Shutoff Tire Inflator, Booster Pack for 10.0L Gas or 8.0L Diesel Engines

This jump starter pack is awesome. It will start a vehicle with a completely dead battery with no problem.Another bonus is the air compressor and lights. Well worth the money.

I've used mine to jump my 7.3L powerstroke multiple times when the batteries were going out, as well as multiple medium size utility tractors (30-40hp). I've also used it to top off numerous tires on lawn mowers, trailers, and vehicles, including my truck tires that I run at 70psi. It takes quite a while to recharge it via USB (over night), but it's done everything I've asked of it. I have a slightly smaller version in my car now, and I'm slowly trying to purchase a few more so that my wife and daughter both have them too.

I would give this 4 stars based on the product alone. The issue is that Lokithor will not respond to questions and the only thing I have found is a email through their website. A product is only as good as the company making it and clearly they do not care to respond to their customers so shows how great their support will be if it fails. My only reason for 4 stars on the product is the fact that it has 8awg wires on the jumper cables, the amount of power this has if jumping a diesel truck (like mine) then clearly these will fail. The best part is you can buy another accessory kit just like the one it comes with from Lokithor that then has 6awg wires on a similar looking jumper cables or upgrade to better jumper cables that also have 6awg wires that in my opinion should be standard on this bigger unit. Also you really need a high output usb-c power supply to charge this efficiently and should probably be included. Just to be clear 6awg would be better than the 8awg but for what they claim it can jump it should be 4awg with a better connector on the device to handle that higher amperage.

im giving it an overall 1 star because after the first use i deicded to charge it due to it being 1 bar and it wouldn't charge and i thought it was the charger so i used a different one but had no luck.. it's been about 90+ days since i bought and got unlucky with this one.. ive had there previous model but misplaced it and that worked perfect. i do recommend this item.. i also gave it a 1 star because i contacted the company on their website and have yet to hear from them.Overall it's a great item but as i said i got unlucky with the one i have with it not being able to charge :(Update**04/19/24The customer service team is the best! They reached out to me and sent me a new one that works perfectly and charges! Thank you so much! You guys are the best!

Update on the review - Lokithor reached out to me regarding the issue and offered to make it right. The communication was prompt and polite, and the company really backs up their product with their actions. Bumping up to 4 stars.*****Bought this as it was rated 3750A for 10L gas engines. However 6 months in, after being used less than 5 times, it now struggles to start the 3.6L engine on my Jeep Grand Cherokee. Friend's starter from Noco with less power rating seems to start the car fine.That being said I do like the feature that shows the voltage of the battery and the built in air pump has been useful in the 1 or two occasion that I've needed. Overall, just really wish the power was enough to start the Jeep.

I topped off my tires and charged a tablet and phone at the same time using this thing. This will also be great to carry with me in my truck to start up dead batteries! The inflator worked well by setting it on 38 lbs for my truck tires then just let them all fill to match since this turns off automatically. I had 2 cheaper inflators before they burnt up after a few uses. That's why I feel it was also a good investment buying the extended 4 year no-haggle warranty for it. I'm sure inflating tires puts the most strain on these things. The nozzle got very hot just topping off 4 tires! I'll update if or when something goes wrong!

So far has jump started things very well. The push buttons stick in when pressed, which is already a problem, started almost immediately. Also, the cables are tiny(thin). I thought they were bigger from the pictures I had seen of this. Compressor is painfully slow, so more of a gimmick to me. 2.5/5.

After looking at these things for over a week and totally messing with my brain I settled on this one. I’m glad I did. I have a GMC Yukon and this inflates the tires in no time at all. My son has a Duramax 6.5 diesel and it jump started it no problem. For it’s size it’s amazing. It’ll also recharge your cell phones which can be handy in a power outage. The compressor is quieter than a lot of them. You can’t go wrong with it.
