Fanttik X9 Ultra Portable Tire Inflator for Pickup Truck, RV | 3-in-1 Air Pump, Power Station, Flashlight | 6X Faster Inflator with Digital Gauge | Air Compressor for Light Truck, SUV, Compact Car

*TRACTOR TRAILER 18 WHEELER TIRE *I’m not sure if many truck drivers have bought this piece of equipment or something similar but I’m making this review to let truck drivers know that this will in fact inflate a 11R22.5 semi truck tire on a dually and single setup even if whoever installed your valve stems are dumb and don’t put the extended valve stems on the inside tires you can reach in between the two tires and screw it on it’s a little tricky tho but works well. This also works as a very nice battery bank when I go to the lake and the flashlight works very well when in a dark situation. Went from 81 psi to 105 psi in 10 minutes 46 seconds and point 2 whatever that means lol I downloaded a stop watch app to perform this test for yall fella truckers keep on rollin

In my last beast of a truck, I installed a twin ARB compressor, and, it was great, I loved having pressurized air anytime when off grid so that I could air down (and subsequently, air up) my tires. Airing down not only softens the ride over rocky trails, but also increases the amount of surface area of tire that is in contact with the road and can lessen the likelihood of punctures as well, so it is very important.Even though I loved having built in air before, I installed it myself, and I always felt a little uneasy with my own electronic skills, wiring it to the battery, soldering, etc. When I purchased a new off-road vehicle, I wanted a simpler solution. I don't off-road quite as much as I used to either, so I didn't want to go through the trouble (and expense!) of wiring in a new compressor.I did some research on portable compressors and I ruled out the ones that use terminals to connect to the car battery. They work fine, it's just a bit of pain to have to connect to the battery each time. They also get super hot, so you need to wait a bit before winding up all the wires and the compressor and putting it away. I looked at a lot of battery powered ones, but most of them are for regular car tires and can typically only fill a few tires before the battery needs recharging, and they often don't have the power to inflate bigger off-road tires.This Fanttik inflator turns out to be just the solution I was looking for. It is easily capable of filling my off road tires (295 70r17, for example) up to 40 PSI. The battery lasts surprisingly long, I've filled all four tires two to three times around and the battery is still at full. It is easy to charge, using USB-C (for faster charging you would need to buy a DC or AC charger with higher wattage; Fanttik and other companies like Anker sell them). It also has the ability to save multiple different pressure presets, so you can just hit a button and it will inflate up to 35 PSI or whatever you've set, and then it automatically shuts off when it hits the set pressure.While this is not a direct replacement for a built-in off-road compressor, it is a perfect in-between solution for me, someone that still goes off road a couple times a month but no longer wants to mod the heck out of their vehicle.

2nd EDIT: My replacement unit showed up today and it was fully charged and worked right out of the box! I was able to take it outside and test it on my work van and put pressure in all four tires without any issues. Thank you to the excellent customer support and the quick response at getting me a replacement unit.EDIT: I reached out to Fanttick support and gave them the order and video of the issue. They stated they are sending a new one to me. They also provided a label to send the old one back. Once I receive the new one and test it, I may up this again to 5 star. They jump to 4 star for being so responsive and easy to work with.I bought this to use with our Class B RV Mercedes. A couple of issues I noticed. 1) On the Mercedes tires or any tire with high pressure, you can't screw the nub on all the way or the backpressure created makes the inflator think it has hit the required pressure and shuts off. You have to let the tire "hiss a SMALL bit so that it will properly inflate. 2) I used this 2 times, I always kept it charged for emergencies. I tried to use it after not using it for about 4 months, and I get no powerup at all. Even with 5% discharge rate for standby it should still have at least 70%. I plug the charger in and nothing happens for a minute...then the display lights up and shows fully charged but NO power input (the charger is plugged in). The charger is 65W as recommended and I am using the provided cable. I have reached out to customer support. If I get a proper resolution, I will update the review, but as of now I am upset at spending $249 and getting trash. My other $70 battery inflator is much weaker and has none of these issues.

Use this pump a couple off times with no problems , set pressure and go . $$ well spend

Works great happy with it I want try another one out.

Works like it says very handy

Was a little hesitant to spend the money.......but this thing kicks ass. Fills my F450 dump truck tires 10x faster than the average inflator.Fantik puts out excellent products
