This jumpstarter/inflator came so close to being perfect, but ended up having a fault that will impact its usefulness to some purchasers. I am one of those. Although I will carry it in the vehicle when I travel, I primarily purchased it for using it on my lawn equipment around the house. Cub lawn tractors are notorious for not charging their batteries, and always needing a boost. This jumper will be almost perfect for that. I tested it as soon as I had fully charged it, although it was almost full when it arrived. My little tractor turned over faster than at any point in its history of belonging to me. The difference with this, compared to just trying to start it with its own battery, was almost beyond belief for me. No more having to push my mower to a power outlet and a corded charger when it is dead. I love that.
And the air compressor is great as well. It was well thought out. It has several preset pressures, such as car tire, basketball, bicycle and some others, but it also has a setting where you can set the pressure at the exact number that you are looking for. For instance, my pickup wants 60 in the front and 70 in the back. There are not presets for that, so I use an exact setting. But the presets are great for casual use.
I like that the displays are large and clear. I like that it came with a carry bag with strap. I like that it is compact, even while being powerful. I like the way it looks. In fact, I like almost everything about it.
So, what did I not like that made me take a star away from perfect? Actually there were two things that I did not care for, but only one affected the stars. The other was that it does not come with written instructions. You need to scan a QR code. I am old and am not comfortable with some tech. I only use my phone for talk and text. I would have preferred a booklet. But I certainly would not have reduced its stars over that. What limited its function for me, and the number of stars that I thought it earned, is the length of the jumper cables. They are miniscule. They barely would let me reach the tractor battery and still put the seat down so that I could start the tractor. They did reach...but only barely. BUT, my wife drives a Jeep Grand Cherokee, and the batteries are under the passenger seat. These cables will reach under there and connect only with great difficulty. And I suspect others will find other situations where longer cables would have been handy. It would have been so simple, and would have cost so little to have made them a little longer, to where they would fit more applications. But they did not do that.
Still, I do like the unit very much. It takes up almost no space and will easily fit under a car seat. It came with inflation accessories, and a bag to keep it all together. I have attached a pic to show what is in the box.
So, in summary, it is absolutely a great unit. A buyer would just need to make sure that the cable length will work for their application.
