This replaces my electronic airpump. I had the anxiety of needing a jump start. Now, this versatile device can inflate tires and also give me jump start -if I need one. The unit seems well built and rugged. It has several useful functionalities: air pump, jump start, phone charging, flash light, blinking white light, SOS signal. It can also measure the car's battery voltage.I tested the pump function, I connected it with my bicycle tire, and pressed a button -it was easy to use. Also, it mentions that it has safety for shorting two terminal -which will be good to have for peace of mind.

I recently purchased the LOKITHOR JP400 Jump Starter with Air Compressor, and it has exceeded all my expectations. Living in Phoenix, where summer temperatures can be extreme, having a dependable jump starter is essential. This device not only jump-started my 8.5L gas engine effortlessly but also handled my friend's 6.5L diesel truck without a hitch.​The built-in 150PSI air compressor is a game-changer. I used it to inflate my tires quickly, and the auto-shutoff feature ensured I didn't overinflate. The ConnectMax technology provides a safe and efficient connection every time, giving me peace of mind.​What I appreciate most is its portability and user-friendly design. The compact size makes it easy to store in my trunk, and the intuitive interface means I don't have to fumble with complicated settings during emergencies.​Overall, the LOKITHOR JP400 is a reliable, multi-functional tool that every driver should have. It's worth every penny for the safety and convenience it offers.​

Love the idea of jump starter and air compressor, but had to replace the 1st one due to cross threading of the air hose connection. Works well, but worried I may have the same problem with additional use.

Great investment

Great gift for my son! He keeps it in his truck at all time. He likes it so well that he bought me one too 😁. I was glad he did because I needed it one day and it works perfect. This is a must have for every car or truck. There is a case that you can buy sperate for this item as well.

The media could not be loaded. I needed a portable inflator because I always want to keep my tires pumped and I have a one tire that loses ~ 0.3 psi a day. This jump starter and air compressor combo is perfect for topping off tires and the occasional jump start. Previously, I had a physically larger version of this product which I was impressed with already, but I needed a smaller version to carry around in multiple cars.For the air compressor function, it does take longer to inflate than the larger version; another feature was the over-temperature protection which I encountered when I was filling up a tire from ~30 to ~40 psi, it was an annoyance for me because I had to wait till it turned off before doing another tire, so I wouldn't recommend filling a tire more than 10 psi using this.I also like that the display shows the charging wattage when plugged in to charge. I've hit 15W which is pretty quick and should take ~2 to ~2.5 hours to charge from empty to full. The display also shows the pressure with a decimal place accuracy which my older jump start/inflator did not (showed only whole numbers).Flashlight is minimal but could be useful in an emergency.

The media could not be loaded. The digital display gives all the information you need, and 5 buttons control everything.But, the small size is what makes it 5 star. So many features: jump starter, air pump, power bank, light, and voltmeter. Comes with jumper cables, air hose, USB-C cable, air nozzle adapters, manual and storage bag.The peace of mind and Good Samaritan potential are worth the price.
