JP400 Jump Starter with Air Compressor, 2500A 12V Car Battery Jumper Starter Portable (8.5L Gas/6.5L Diesel) with ConnectMax Tech, 150PSI Tire Inflator, Auto-Shutoff & Dynamic Dwell

Excellent jumpstarter to have in your car. Used this 3 times so far. Holds a charge for at least 3 months. Definitely helps to have 2 people, so you can time it right. Otherwise, it can be tricky. Still works though, just might take a few tries.

Great Item Great Price

This thing works really well. I have a Toyota truck with a dodgy battery. Unfortunately I've had to use this about five times in the last 2 months. But it cranks the truck every single time. I just make sure to keep the battery topped off. I would definitely recommend this for every car care kit.

Powerful jump starter and tire inflator. Inflates tires quickly. Pressure gauge is accurate. Unfortunately, the default pressure setting for automobile tires is BAR not PSI. I was able to work around this but could not find any way to change the default. No response to my inquiry from the vendor but this is still a quality product despite this one annoyance.

great 👍🏾 tool. easy to use. for cars, motorcycle, bycicle, ball 🏀

This thing is awsome for the price . It jumps my beater gmc 2500hd

First time I drove my car after I hit this, I noticed my low tire pressure light was on. It was so easy to pump the tire at my house and feel safe! I have one in my car and my wife’s car now.

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.
