Air Power America 7500 70 PSI MaxAir High Volume Tire Pump

I have purchased imported tire pumps and 12 volt electric compressors for inflating vehicle tires when no gas station is nearby. Here's the problem: On all of them, the rubber hose starts to crack and deteriorate after 5 years. So the few times when I really need them for a flat tire, they are not there for me. In addition, the electric compressor inflators are not reliable. Their quality is cheap, appears cheap, and proves cheap every time. The battery boosters with the built-in air compressors have also let me down; after 5 years, the lead-acid battery no longer holds a charge. And the hose is the same poor quality, subject to drying out. When I was bringing one of the manual tire pumps into my workshop to repair the deteriorating hose, I noticed a 23 year-old "Big Boy" brand made in USA tire pump sitting there. I compared the hoses; the old USA manufactured pump had no signs of oxidation or cracking at all; the China manufactured pump's hose would crack each time I bent it. I have AAA, but knowing that I'll get a flat on a dark, cold Sunday night on a lonely highway where there is no cell phone service, etc. ("Murphy's Law") I like to have options. So I put my old "Big Boy" pump in one of my vehicle's trunk, and purchased two more Air Power America MaxAir high volume tire pumps for each of my family's other vehicle trunks. These pumps appear to have the same long lasting hose as my 23 year-old pump. They have no electric motor to act up or take 2 days to inflate a car tire, and don't need to drain the vehicle's battery for inflating a tire. For the same (or lower price) as an imported pump, I have piece of mind in each of my vehicles, without taking up much trunk space, adding weight to my vehicle, or worrying about battery or hose maintenance. This is a simple but reliable, domestic product useful when no help is nearby, or should I need to help another motorist in distress because they don't have my obsessive-compulsive nature about quality tire inflators!

Works OK, but as mentioned by several reviewers, the effort required was more than expected. Simple math should give you a rule of thumb on the force required to reach your target pressure - suggest that your weight be roughly 4x target pressure (e.g. 40 psi target -- 160 lb; 50 psi target -- 200 lbs). The larger than typical barrel volume reduces the number strokes needed to reach your target pressure obviously, but if you are light in weight, be prepared for a workout.UPDATED 2//14/2017. Pump failed on second use. Major leak at the hose connection to the base. You may be hitch-hiking if you rely on this pump as your roadside emergency pump. Seller accepted return & provided prompt refund -- thanks!

I bought this a while back and didn't get a chance to use it until this weekend. Filled up tires on two cars. It worked well. Do not pump wildly. The The trick is to apply continuous pressure until the handle reaches the bottom. Use your body weight to slowly drive the handle down. The pump is not secured to the base and the handle is not secured to the cylinder. I think it is an interesting failsafe as you will have a hard time breaking a part of the pump before one of these items give way. It is easy enough to put back together. The pump itself seems very solid and durable. The cylinder and shaft are both metal and the bottom section is solid plastic.If you notice the pump popping out of the base repeatedly, check whether or not the pump was secured to the valve properly.I would say it took about 50-60 pumps to get from ~25 PSI to ~35 PSI.One issue is that at higher PSI the pump starts becoming more difficult to use. I had no problem getting to 35 PSI and getting it to 40 PSI was noticeably more difficult. I wouldn't push my luck using it as a bicycle pump if you had to get it up to something like 50 or 60 PSI.One con is that the air hose is a bit short. You are going to have to stand a foot or so from the tire (especially if your air valve is at the very top). This could be an issue if you are expecting to use it on the side of a road.

I really wanted to like this Made in the USA high volume pump. It's a little shorter than I imagined, and the hose is less than 22" long, but I can deal with that. When I first stroked it however, I could hear something scraping inside, so I popped the top off to have a look inside. The scraping was caused by the large metal washer that acts as a guide and supports the leather cup. It is mounted a little off center, and drags. I'm used to seeing a plastic piece used as a guide, to avoid scraping the barrel, and I could make one If I need to, but I figured I'd try re-centering it first. No such luck. Every other pump I've ever used had the business end of the plunger held together by a nut on the end of the rod, so that you can replace the leather cup when it wears out. This one is just swaged together, and cannot be repaired. (see picture) The worst thing about that is, it ~will~ need to be repaired if it sees much action at all, because the of the rough unfinished weld on the seam where the tube was welded together. (see pic) It's mirror smooth on the outside only, not where it matters. Oh well. I'm going to give it to some one who I know needs one, but very infrequently. Hopefully it will hold up long enough for them.
