Updating review.

It's now May 2012 and the pump is still running like a champ.

Keep in mind I don't use it that often, just once or twice a month.

Plug has held together. I do wish it had a longer cord or hose, but it reaches

every tire I've used it on so far.

--------

Ok.. I didn't get this from Amazon. I got it from Steve's Tools for about 5$ more.

Needed it now because my old crappy $15 pump finally died.

Pros.

Real smooth and well balanced. This thing doesn't jump around at all.

Fill speed is good, but not for large tires.

For those get the version that clamps to battery terminals.

This one topped off my P255-75R15 in decent time.

However, filling up my 60PSI doughnut spare took a while.

I don't think there is much head space for the higher pressures.

This is where the screw-on air chuck was useful.

The pressure gauge actually works and is accurate.

The switches are separate for pump and LED lights.

The handle is actually a metal heat shield for the output.

Run this pump for a while airing up a 60 PSI spare and you

will understand why it needs a heat shield.

The unit comes with a bag. Not the highest quality but

sufficient for storing the pump and a few other odds and ends.

Cons.

The screw-on air chuck can be a pain, but just overfill a bit before taking it off.

The air hose is adequate for reaching front and back tires on one side,

but you have to move the pump from one side of the vehicle to the other.

The LED lamps aren't that bright, and the blinkers are only three white LEDs.

You have to put in a red filter. They should have been red LEDs.

I'm reserving comment on the lighter connector. Looks a bit cheap compared to the

rest of this unit.

All in all I'm happy.

Honestly, I was impressed with this compressor when I first opened the box and the first 2 or 3 minutes it ran...

The price wasn't bad but this compressor sucks. If you just need one to fill tires you'd be better off with one of those pieces of crap autozone sells.

To begin with the connecting rod for the piston won't stay attached to the counterweight that mounts to the motor shaft. On top of that the counterweight won't stay attached to the shaft either. After breaking about 90psi with this thing the connecting rod and/or counterweight comes free and just bangs around inside the plastic cover.

I have machined out both pieces to keep them from slipping but the "seal" on the piston is shot and it will no longer break 80psi.

Small example of the crap construction...the motor shaft has a flat spot on it and the counterweight slides over that. But these idiots put the set screw on the round side of the shaft...and they use an e-clip to hold the connecting rod on. (it flies off).

crap crap crap, don't buy this thing unless you need a shiny red door stop.

The unit operates as advertised. It is light weight, very portable and inflates SUV, car and bike tires very quickly. The problem I am having is with the screw on hose connection to the tire's valve stem. I am never (and I mean never) able to screw the end of the air hose onto any SUV, car or bike tire's valve stem. It simply won't screw on. I therefore need to manually hold the end of the hose onto the valve stem to inflate a tire. I need to hold it in the exact proper position or the air will quickly leak out of the tire. Frustrating to say the least. There have been times when I thought the tire was inflating to find out that I didn't have it in the proper position and the tire was actually deflating.

I just sent an email to Q Industries to find out if the "Optional clip on tire valve inflator extension" that Q Industries sells on their website for $5, will work with the HV402A that I purchased. If this won't work, I am hoping they can provide another alternative.

If they don't make a different adapter or hose for this unit that actually works, I will need to deem the HV402A useless and find another portable air compressor. And that's a shame considering I spent $50 to buy this unit and it's only a few months old.

The second time I used the compressor it stopped functioning properly. I am now trying to return it and will not buy another. I received a replacement unit for free, it was also defective, I received a third unit free and have been using it every since. It works great. The customer service was excellent!! I wouldn't hesitate to buy a replacement.

I've been using to inflate my slowly leaking tires through the winter. It's kinda slow but gets the job done. LED light comes in handy.
