   Tired of paying two bucks at the gas station, I have always yearned for a portable tire inflator. Here are two of the most popular models compared (Please see photo). Which is fastest, best built and most reliable?AVID TIRE INFLATOR OVERVIEW:Both of these cordless inflators resemble drills with similar lithium-ion batteries. The Avid has a 20 volt battery as opposed to the 12 for the Autder. Is this a real world advantage? More voltage means how much power the battery generates. Thus, the Avid is a bit more powerful and fills the tire a bit faster. Avid states that you can inflate three to four tires fully depending on tire size. For 214/60 R16, as an example, you can fully inflate three tires from flat and each tire would take about five minutes.For just topping off a low tire, the Avid works easily and relatively fast. Its maximum pressure is 100 PSI. I increased my car’s tire pressure from 32 to 41 in about 90 seconds.For accessories, you get a car adapter, a couple of inflation adapters, and a handy storage bag. You can buy an inexpensive second battery from Avid.AUTDER TIRE INFLATOR OVERVIEW:The Autder looks like my Dewalt drill but, alas, the batteries do not swap. The 2600mAh battery will last a long time. The mAh number determines how long a battery will hold a charge. This one should last a year in your trunk if not left out in extreme weather. As long as you are just topping off your tire pressure, the battery will last through many charges. If starting from a completely flat tire, the size of the tire with affect how much air you’ll get before running out. Figure on two tires if both are totally flat. In real world use, this is not a likely scenario, though. Maximum pressure is 120 PSI.For accessories, you get a great car adapter, a generous supply of inflation adapters, and an excellent storage bag. Audter does not sell extra batteries so you are limited to one.EASE OF USE: AVID VS. AUTDER:Both are equally adept at quickly topping off a tire, easy to use and were within 1 PSI of my trusty gauge. I found the Autder more intuitive and convenient to work with although both are quite usable. The Autder shows both the current pressure and desired pressure at the same time. Strictly used as a gauge, it’s easy to read, too. The available battery capacity left is also easy to access in the same area as the other readouts. The Avid can be toggled between set and desired pressures. The Autder is slightly quieter.WHICH HAS THE BEST WARRANTY AND SERVICE:Avid’s warranty is listed on Amazon as two years. Inside the box is a warranty card. Both companies respond promptly to questions.Here’s what Autder says about their warranty: “We promise you with one-year warranty, actually, we are not permitted to list the warranty on the listing according to amazon’s rules.” That’s unusual. No warranty info is included in the box.RECOMMONDATIONS: WHICH IS BEST?Both air compressors are reasonably well built, similarly priced and get the job done confidently. Both have a convenient auto stop function when desired pressure is reached. At the time of this review, the Avid was about 15% less expensive. Consider this when deciding: The Avid will fill faster yet the battery won’t hold a charge as long in storage. The Autder will last a longer time in the trunk but at 12V vs. 20V for Avid, it won’t inflate quite as fast. You can buy a second battery only for the Avid.Both inflators rate 5 stars for ease of use. For warranty, the Avid rates 5 stars for a generous two years. With no option for replacement batteries, and a stated one-year warranty they say they are not permitted to list on Amazon, Autder’s service after the sale is not as confidence-inducing.

   So easy to use. It filled my walker’s tires in a flash to just the right psi. Love the fact that it came with all the needed attachments, battery and car hook up. Other models make you pay extra for those. Also comes with a great carrying case which makes it super easy to store and transport. Love it.

   I purchased this primarily to use to top off my e-bike tires and I found it easy to program the desired tire pressure and the pump automatically shuts off when the pre-set pressure is reached. Due to a car accident, we had to rent a car and found that one of the tires has a slow leak, loosing about 5-6 lbs every 2 days. This small pump was a perfect and convenient way to add air to the tire as needed. Thing is, inflating the tire from 32 to 37 psi takes about 4 minutes and I was able to only get 4 uses before the battery went dead. The pump was pretty hot. I can’t see this thing having the battery power to fully inflate one tire, much less adding any more than 5 psi to each of the tires, if needed. However, included in the kit is a 12V cigarette plug adapter. The unit works well for my bike tires and having it in the trunk of the car for emergencies is better than nothing. I just hope I can depend on it to fully inflate at least one tire if needed.

   Call me very happy. I had just returned two Airmoto (cute little small unit, but was totally useless. it had taken over 3.5 min., to put 4.5 lbs of air into car tire, before it started taking air OUT of the tire, and the hose turning very warm! ) units, due to the unit failing miserably in attempting to inflate my car tire. For this AVID power portable unit I had researched many product review sites, where it had received a top rating. I just used it to pump up a flat bicycle tire from 0 to 40 PSI, which it did in less than 1.5 minutes. It inflated the 2nd tire from 23 PSI to 40 PSI in just about 30 seconds or so. The battery indicator was still showing ‘full’ after the 2nd tire. Yes, I know, difference between a car tire and a bicycle tire, for inflation purposes. With how I saw it handle my bike tires, I see zero reason why it cannot handle my car tires, for a PSI of 35. I had purchased two, one for each car, and had purchased a third for a X’mas gift. Oh yeah, I bought a spare battery too, only because of experience with battery operated tools where the battery dies. I like ‘backup’. So, would I recommend this pump, yes, I would.BTW, if you are wondering, yes, the unit will display the current PSI of your tire, providing you do not do something stupid, like I did. I clamped the hose on and had a reading of ZERO, even though the tire was pumped up. I fussed about not having a reading, and proceeded to pump the tire up to 40 PSI. The unit would not work! I started ranting about my luck getting ANOTHER bad pump. I stopped and put everything back in the box, preparing to write a sizzling hot bad review on the pump. I then though about something, and went back to check my thought out. I found that yes, I had clamped the hose on, BUT, I had not pressed on the clamp so that it went down and made contact with the valve in the tire stem. I pressed on the clamp, heard the air hissing, and new I had contact, and I clamped down. I immediately had a PSI reading on the screen, and proceeded with pumping up, with no issue. Basically simply, no contact with valve, no PSI reading AND the pump will not work, as it is not connected to the tire stem. 100% user fault at that point.UPDATE:I received the 2nd unit, of my three unit order two days ago. I just opened the box and was prepared to put the unit into my car, after testing it. I noticed a number written on the bottom of the carrying case, in white, which stood out on the dark case. My guesstimate being that this unit was a previously returned unit, which someone had numbered, for whatever reason, and then returned, with the returned unit being sold again, as new, with the white number on the case. I returned it and purchased another unit.

   My tires lose air regularly when the weather changes. Always had trouble getting inflation right using gas station air—and some now charge for air! This product is so great! Rechargeable so no electric cords to run. Easy to read pressure levels. Great for women!!!

   I really like how easy and uncomplicated this air compressor and gauge is to use. Read the pressure in the tires quickly, and I was able to fill them to the recommended levels with no trouble. I used the rechargeable battery but it also comes with a power cord that fits into the cigarette lighter opening so I don’t have to worry about whether the battery is fully charged or not. Comprehensive instructions that make sense, even for someone who doesn’t know auto repair jargon. It comes in a little case so I keep it in the car under a seat, which means I don’t have to rely on finding a place with a working air station when traveling (which is when the “low pressure” light invariably seems to come on). Having this kit just gives me peace of mind. I’ve had too many long trips where midway through I’ve needed to check or top off the tires, so having something that is relatively small but also works is a big relief.

   I’ve used this several times and could not be happier. But time will tell if the coupler/hose, and battery, hold up. This is far more convenient than getting out my air compressor and hose. It’s compact and rides in the trunk. The internal gauge is accurate as it reads within a pound of my manual tire gauge. Gitcha one!

   I got this tire inflator mainly to use at autocross events where being able to quickly adjust tire pressures between runs is a huge advantage over your typical tire inflators that need to be plugged into a 12v outlet in the car to work. Having to plug the inflator in and then deal with feeding the power wire through the door on each side as you move around the car is a bit of a pain, especially if you don’t have a lot of time.This inflator resembles a cordless drill but instead of the drill chuck on the tip it has a flexible air hose. The hose has a quick attachment lever so you can push it down over your car tire’s valve stem, flip the lever, and begin filling. No need to screw on the hose like many other inflators.The inflator comes with a nice fabric storage case that holds the inflator itself (with 20V battery attached), the AC charger for the battery, a “fake” battery that stores a 12v plug and cable so you can power the inflator from your car if the battery has run out, and the instructions.The battery has a button to display the charge level when not installed in the inflator and also has a USB-A port that you can use to charge things like your cell phone right from the battery.In addition to car tires you can also use the inflator to add air to sports balls that use a pin, air mattresses or other inflatables, and bike tires. Adapters for each of these things are included and there is even a little storage area on the top of the inflator itself so you can keep the adapters with it. I hate sportsball, air mattresses, and bikes, so I just leave those adapters in the case with the instructions since I’ll never use them.To use the unit you first charge up the battery using the included AC adapter, then snap the battery onto the bottom of the main handle. The rear of the unit has a small display with buttons to turn it on and off, change the units of measure, and to raise and lower the pressure setting. Simply press the on/off button, then press it again if you need to switch between the various measurement units (PSI, BAR, KPA, and KG/CM are available). If you connect the unit to your tire at this point it will display the current pressure of the tire. If you need to add air you press the up and down buttons until the pressure you want is shown in the display. Then squeeze the trigger once and the compressor will turn on (there’s also a little light on the bottom of the unit to give you a little illumination if it’s dark outside. It will fill the tire to the selected pressure and then automatically turn off. Very convenient. The pressure setting is retained after use so you can quickly move around your car and inflate all your tires to the same pressure without having to manually watch the display and turn off the unit when it reaches the pressure you want.I did notice that my particular unit tends to fill the tire to be about 2 PSI higher than the display setting. So when I want to fill my tires to 30 PSI I set the unit to 28.5. It then will end up filling them to about 30.5 PSI. Removing the hose tends to release a little pressure and then I use a separate dial pressure gauge with a bleeder valve to bleed off the remaining overage until I’m right at 30.The case is large enough that I can also toss my dial pressure gauge (not included) in to the bag and have everything I need together.So far this inflator is working very well. I can typically add a few PSI to each tire and the battery will still show a full charge. So much so that the wall charger won’t even charge it until I run it down some more. So I suspect this would have plenty of charge to refill a flat tire if needed.I typically carry a Viair inflator in my cars as that brand has been very reliable for me over the years. It remains to be seen if this particular unit will be reliable long-term, so for now I may carry both inflators on any longer trips, just in case. For speed and ease of use though this Avid Power model is much better than any corded inflators.

   First, I should state that for most of my adult life I had access to and used a full size air compressor, the type you would see in a professional workshop/garage. Secondly, I have an Avid drill with a rechargable battery. Third, I spent over 4 hours reading, watching YouTube videos and reading reviews before I ordered this device. Once I had selected it, I also ordered the dual action polisher and digital tire gauge. (The gauge has not yet been received.) Lastly, my BMW station wagon I have had since 2006 routinely needs to have the tire pressure adjusted because if the pressure is not close to what BMW has set, it will activate the Flat Tire Monitor. For the last 15 years I have been constantly aggravated by false FTM alerts because the pressure got to low. Even worse it routinely registered it as a puncture to the tire. I have spent more quarters at gas stations adjusting the air than one would like to remember!With that history you would conclude that I would get this device, read the instructions, charge the battery and after checking the tire pressure, inflate it to the indicated PSI. But no from the very first it was a headache. The instructions need to be written as if the person reading them as had no familiarity with either air compressors or rechargeable batteries! This one is not. The device came with the car lighter 12 volt charger attached. I looked at the charger and not being able to get the charging mechanism to connect without forcing it, I thought I could charge it with the USB. Unusual I thought but as it was already partially charged, not a big deal until I could watch a video showing how it connects. (couldn’t find one & finally forced it on the next day) It must have worked as the next day it showed a full charge. Strike one.Because the lighter charger had a notch for the cord to go through, I mistakenly thought the charged 20 volt battery attached to the 12 volt section. Idiotic upon reflection but the entire inside portion of the 12 volt charger was scooped out and as the instructions said nothing about removing the 12 volt charger it took me awhile to hit my head against the wall. Maybe half a strike because this one I should have figured out even without the instructions being clear. All of the parts tightly fit so you have to apply a bit of force to connect and disconnect. I have arthritis and my hands are a real mess these days and I found everything that required connecting to cause problems. An instruction which shows in illustration EXACTLY how the pieces connect would have saved me time and would have been essential for someone not familiar with these devices. You never want to force something and break it. So another half strike for lacking sufficient diagrams. Strike 2.Because I felt so silly about failing to remove the 12 volt charger before attaching the 20 volt battery, I read the instructions over numerous times and took them outside with me for reference when checking my tires. Problem one, the “light” on the base is a joke. It points the wrong direction and only lights up when the unit is in use, so if you needed a light to see your tire stem forget about it. As the instructions said to make sure the threaded part was covered and it was dark, I got a flashlight (as well as really dirty fingers, I would recommend putting some plastic disposable gloves in the case to avoid the brake dust all over your wheels) and once I was attached and could see/feel that the threads were covered, I thought it would be easy. Strike three on the light. The clamp is really hard to press down once attached over the threads as it hits the line and you have so little room to maneuver. My arthritic hands could have been partially an issue so no points accessed.Strike four on the length of the cord. Really who in their right mind thought that was long enough. Two tires had the valve stems at the top, the other two had them at the bottom. They barely reached the valves at the top and I had to hold the compressor up in the air to operate and see the pressure displayed.The instructions next say that when applied to the tire and turned on, it will automatically display the current PSI for the tire. It failed on every tire to do so! The only question is whether that means four more strikes or only one. Being generous I will count it as one. The PSI on one of the tires showed 101 which was really alarming as that would be way overinflated and in danger of rupture. That was the tire that was noticeably low on air, so it didn’t take long to figure out that when it did provide a measurement it was never close to accurate. Strike five.My tires per BMW were to be set at 32 PSI in the front and 38 PSI in the back. I have done this so often that I no longer have to look inside the door to verify the correct setting. If you are new to inflating your own tires, the recommended pressure for the tires is typically on a label inside the drivers door where it closes. If not it should be in your instruction manual and I would recommend writing it on the outside in large letters in case you have to air up in the dark.I set the pressure to 32 psi turned it on and watched the readout. The noticeably low front tire which read a PSI of 101 registered a starting point of 26 PSI (far from the 101 PSI reading!). On every single tire once it got to the set PSI it DID NOT TURN OFF! I waited as it went up in half increments to see if it advanced beyond what I had set, but after a few moments of it continuing to operate without the gauge showing an increase over what I had set, I turned it off and disconnected it. That is potentially very dangerous, you don’t want a tire blowing up in your face. A huge strike six. I went back a few minutes later to see if I could now get an accurate PSI measurement on any of the tires, but no so luck. As I didn’t have my other pressure gauge, I was unable to determine what the actual PSI of each tire was and guys, that is a real bad problem. Under no circumstances should you rely on this device to accurately read the tire pressure. This is “casually mentioned” in the instructions, but in the listing it states that the device can be used to gauge the current pressure as well as working as an air compressor. You can purchase a good digital gauge cheaply and I plan to get one. I had the old fashioned kind, but I found in the dark a digital gauge is far easier to read.If I had just casually selected this item I wouldn’t be so aggravated. I tend to suffer from analysis paralysis and spend far too much time researching an item before I buy it. When it fails to operate or lacks sufficient instructions, I am always disappointed which leads me to further over research the next thing I purchase. The only thing I wish I had done differently was to video the entire process. I have operated numerous tools with an air compressors and adjusted my tire pressure for over 40 years, I can only imagine how difficult operating this would be for someone who lacked familiarity.Do I need to give it another go? Yes I will when the extension gauge arrives. If however after changing it with that one, I don’t have better results, it is going straight back. I will update this review either way.On the positive side, it is a great size to keep in the car, it comes in a nifty little case and the 12 volt charger had a fairly long cord, so I think if you used it that you could easily reach each tire. Also the 20 volt battery charger could be used to power up anything you have which charges with a USB connection. I particularly liked that as I am forever forgetting to charge my phone and having a battery pack in the car would be useful.

    I really get tired of having to go to a gas station to top off my tires, and hate always needing a bunch of quarters to put in the machine, then rushing to fill the tires before it times-out. Some machines have card readers, but I don’t trust them because you never know if the machine has a skimmer on it.I was skeptical if this machine would be reliable, but I’ve been using it for several months and it has worked every time. Occasionally it can be a little finicky when you press the trigger to start inflation, but I’ve always been able to get it to work quickly, usually by picking up the tool and holding it instead of trying to set it on the ground. I also love that when you first attach the hose to the tire stem and press the on button, it tells you what the tire pressure is without having to use a separate tire gauge. It’s critical to be familiar with the instructions and follow them precisely, including waiting 5 minutes after each tire before doing the next tire. I recharge the battery after each use and it’s important to unplug it immediately after it charges fully. As a woman, I’ve never been much on pink, but I got the pink color and I really like it.
