3.0 out of 5 starsQuick, quiet, but with one major design flaw
By Chris L on January 18, 2009
This inflator is well designed, works quickly and quietly, and comes in a nice storage bag to stow away in your car. It does have one major design flaw which is the purpose of this mini-review : the screw-on valve adapter. Most inflators come with a quick-release type adapter. This one comes with a screw-on adapter. It's good because it means a secure seal, but it also means that it lets a good 2psi of air back out of your tire every time you unscrew it. The problem is that as you unscrew it, the seal is broken with the valve, but the pin in the valve is still held in so air begins to escape. If you're quick, it lets out about 2psi. If you have large fingers, are elderly, or otherwise slow at manipulating small objects in tight spaces, this could let out up to 10 psi while unscrewing it. This makes the whole inflator questionable because whilst the built-in pressure gauge is bang-on accurate while the hose is attached, it's meaningless once you unscrew the valve adapter and let a bunch of air out. In the end you will find yourself over-inflating your tyres by 2 to 3 psi just to compensate for the screw-on valve adapter. It's a shame because otherwise this is one of the best inflators I've owned.

1.0 out of 5 stars"Don't Buy This Item!!!"
By WCoastGuynCA on April 22, 2011
I purchased this unit for emergency use. Had it in the trunk of my car for about three months. My daughter called to tell me she had a flat tire. I drove to where her car was located. Plugged the unit into her cigarette lighter outlet. It ran for about twenty seconds and stopped. It blew the fuse on her lighter (10 amp. I then tried it on my car's lighter outlet (15 amp) which it also blew.

Tried to return the unit to Pep Boys but since I had opened the box and it was beyond thirty days they wouldn't allow me to return it.

Clerk at Pep Boys said they'd had problems with the unit blowing fuses.

1.0 out of 5 starsAir hose split third time used
By NM bookgirl on August 26, 2008
Was using this to add air to my tires - the third time I used it - the curly yellow air hose split at the top. It has a three year warranty with a company Q Industries that has no phone number. Not sure it is legit. Will try and mail the air hose back with the receipt - but clearly this is not a quality product.

5.0 out of 5 starsLittle Air Compressor that Could !!! Wow !
By J T. on December 8, 2007
Tires were running low on air during the cold spell and this little compressor came through ! Small and lite weight its just what the doctor ordered. This unit is easy to hook up and operate. Air gage is attached to read while filling. Unit is made of mostly of steel and not plastic. Unit does not walk away when turned on and is extremely quiet. This is a tool and not a TOY !! 10 foot cord plugs into cigar lighter anywhere for ease of use. 16 foot air hose is great. Total of 26 feet from cigar socket. Case is a nice touch! Takes 1 minute to fill tire. 30 liter per minute flow rate. For cars this unit is great ! If you have a RV or truck you may want to upgrade to 1050. Over all I would rate this unit A+++++. J.T.

5.0 out of 5 starsSmall but powerful
By rboy910 on November 21, 2007
Verified Purchase
This little air compressor takes up very little space and took me from 28-35psi in 30 seconds for each tire. The carrying case is very handy and fits everything in there without any force. Package came with a tire guage and attachments to inflate bikes and mattrasses. No regrets here; beats waiting in line at gas stations for air.

1.0 out of 5 starsIt will not just blow your mind!
By Karen Oden on April 14, 2011
It will also blow the fuses in your car for the power outlet in which you plug it in. Happened to both my 12V power outlets in my 2011 Hyundai Sonata and my 2004 F-150 XLT.

5.0 out of 5 starsQuick & Quiet
By BM34M on December 23, 2007
First of all I saw this cheaper at a local auto parts store...Damn!
$13 cheaper...Damn again! I am happy to say that this product works very well and is very fast. I really like the coiled air line which makes the reach even longer and adds a professional looking touch to it. There are only two down sides that I see. One is no quick release lever you have to be quick while unscrewing the air connector or you may lose a half pound of air. 12/30 which means that for every 12min of use it needs 30min for motor to cool according to the manual.

Those two downers should not be a real problem considering how quick it inflates! The screw on method takes me back to the days of the old bicycle air pumps....I'm getting quite used to it plus I don't have arthritis in my fingers. If you do I suggest a kind that has quick release.

Ooops! forgot to mention it comes with a handsome carrying bag nice touch!
Also, very sturdy on the ground doesn't jump around like my old one.

1.0 out of 5 starsBlows fuses!
By Alfred Mikula on April 4, 2010
I used once before, successfully, but the second time I used it, it blew a 15A fuse in my car! I was able to finish up with a different power adapter, but when I used it in my other car, it blew a 20A fuse! According to product literature, maximum power draw is supposed to be 15A, so it shouldn't have blown either fuse.
