FanttikX8 APEX Tire Inflator Portable Air Compressor, 1 Min Fast Inflation, 150PSI Cordless Tire Inflator with LED Dual Screen, Suitable for MPV, Car, E-Bike, Motorcycle, Up to 26.3″ Tires

Another reviewer captured my goal for this pump too. Modern cars with their tire pressure monitoring systems are valuable safety improvements but they are total nags. Every time you get a warning you have to drag out compressors and extension cords that are great for filling many tires from zero pressure but tedious to deal with when the pressure needed is a few pounds. On paper this pump and others from competitors look great for topping off tires when you get the pressure warning.The unit is not large or heavy but it is larger and heavier than I expected from descriptions. Its about the size of a water bottle and heavier because metal is heavier than water. The heft hopefully indicates a well built product that will last a long time, but no guarantees of course. I got the standard package which has all the bits that I need. If the battery rating is important to you then I don't know what to tell you. The advertising copy says 7800mAh but the product manual says 2600 mAh. It is also rated at 28.86Wh and 12V which implies 2400mAh. Doesn't matter to most of us but if you obsess over this you might be disappointed in this product.Upon receipt I charged the unit as directed. It does not com with a charger but you probably have a shoebox full of USB chargers you can use. It appears the unit can accept up to 3A but I charged mine from a 2A USB charger just fine. If you use a lower current charger your charge times will increase. I didn't carefully note the charge time on mine but after use it charged from 1 bar to full in about 2 hours.The thing that prompted me to buy this was of course the pressure warning on the dash on one of our cars. They were last filled when temperatures were around 90F and now they were around 30F. I needed to put 7 psi into two tires and 8 psi into the other two. They are 225/65R17 tires. The hose and adapters seem high quality but of course no adapter is needed for Schrader valves on car tires. The hose is long enough to reach a valve at the 12 o'clock position on my car and would reach a valve a few inches higher. The unit is heavy enough that you probably would not want to let it dangle from the hose. The unit is easy to operate and the instructions are clear. I filled four tires in 15 minutes. You connect it, turn it on, and you can then do other things until it shuts off. It is a fire and forget weapon in other words. The battery meter had dropped to two bars when the fourth tire was finished.Well, it wasn't complaining but we have another car which had last been topped off in the summer so tried to fill those tires with the remaining charge. They are 205/55R17 tires and one needed 5psi, the others 6psi. It took about 10 minutes and the battery meter was flashing as it completed.So, I am happy with the purchase. It does exactly what I needed to do and it is much less fuss to use than my more capable compressors. I might not be able to top off both cars on the same charge when they need it but that is a minor inconvenience, especially since they rarely both need it the same day. I have not used it on bicycle tires but the nice Presta valve adapter should make that easy. I also have hand truck and snowblower tires that need filling and this should do those just fine too.It's a few days later and snow is coming so I used the pump to fill the tires on the snowblower. While I was at it I filled the tires on our hand truck and two 26x2 and two 29x2 bicycle tires. It made short work of these smaller tires and it took 1 to 1.5 "bars" of battery power. It was very easy to use on these small tires too, the Presta valve adapter worked perfectly. I forgot to mention it before but I don't happen to have a lab grade pressure measuring gauge so I compared the pressure the pump produced to a medium quality analog dial gauge and a typical digital pressure gauge. These three consumer devices agreed to within half a psi.So it is accurate, easy to use, and works quite well for filling a wide variety of tiresl.

I've kept on top of tire pressure for many years, likely because I've had electric vehicles where range is an issue. I've done that with a corded tire inflator and a digital tire pressure gauge. The digital gauge works well but the tire inflator doesn't have a cut-off at a set pressure. In practice this means you end up over-inflating and then manually deflating to get to the pressure you want. Also the cord means the inflator isn't particularly mobile, and using it invariably involves dragging out an extension cord. Not the end of the world but not super easy either.The Fanttik X8 resolves these inconveniences. Since it's battery powered it's super mobile. Not only does this make it easy to move around the garage, you can also put it in the trunk and take it with you (it's very compact).The inflation process is 100% automatic. You just screw one end of the inflation cord onto the tire -- nice connection BTW -- dial in the desired pressure, and press to start. When the pressure hits the top of the set pressure the inflation pressure stops.Overall this is advance over what I have been doing. So five stars.I only have a couple of quibbles. One is that a slightly longer inflation cord would be nice. As it is now, if the tire stem is on the top of the tire you have to set the X8 on the bottom. This isn't as stable as being able to set it on its side. The second quibble is that instructions didn't make clear that the tire connector was actually part of the inflation cord. They showed the tire adapter but didn't show it connected to the cord.On the subject of instructions and packaging, other than this the instructions were very clear. And the packaging was rather Apple-like and super nice..

This is an absolute game changer for us. We owned previous vehicles with compressors included, but our current vehicle does not. The tire pressure in our 2022 SUV sensor comes on at least 2-3 times per week. Dealer can't figure it out, no luck with anything, so I keep this with us. It is fast, easy, and does the job. Has a long life. I generally only recharge it 1x per month. Great for blowing up basketballs, soccer balls, etc as well as pool toys. I highly recommend and have bought one for all of my family members. Makes great gifts.

This has been very useful, without every thinking I would really need it, I wanted to be prepared. I use this about once every month and it always has battery because it HOLDS ITS CHARGE. That’s a very important feature for an electronic device like this - a device you need when you least expect it.With that said, the output battery bank did not do much for me. I used it once in an emergency situation and it did not work. It only maintained the already low battery level and then ran out of juice a few hours later.Inflator good.Backup battery - not reliableBecause the inflator and the charge it holds is so reliable and easy to use, I am giving this 5 stars. The backup battery was the selling point that made me buy this, so I am a little disappointed it isn’t a good one, but I didn’t buy this for the battery backup. I bought it to inflate tires.
