Slow but good to have just in case
I bought this air compressor to inflate tubes and rafts from my car as well as bike and car tires.

After two or three uses, I can safely say that it is pretty slow at inflating - slower than the product description would let on. But it beats blowing things up by hand if you're willing to wait.

I will also keep this pump in my car as an emercency tire inflator.

On the plus side, the construction is durable and looks like it will last.

good but looks cheap
i bought this compressor and didn't care much for the previous review, and the price was a factor in my decision, also higher ones blasted some fuses for some users that's why i got this one, for the price it's good and it does looks cheap, it's made in china, it's plug came broken also, didn't fix it yet but managed to use it. it is very simmilar to another one i bought from Dubai except that the one from dubai was biger and costed 20$.
the box says 14 amps, the unit says 10 amps.

I can't say it's not fast it is fast (from 28 to 36 PSI in 30 secs), it is small, but the broken plug and the pressure gauge is not much accurate, so.

it's agood backup for your car but not satsfying for a guy who is looking for well built stuff like me.

Good performer however needs some improvment.....
I just received my Superflow HV35. I have tested it on a tire and I can say that this pump is much faster than both the Craftsman and Campbell Hausfeld models that I own. I didn't do any formal timing but the HV35 aired up a 215-70R14 tire from near flat to 32 lbs in around 4 minutes. Compared to about 15 minutes for the Craftsman pump and over 20 minutes for the CH. Considering it is in the same price range as those units makes it even better.

The HV35 unfortunately is not without issue. Some of the build quality looks questionable(rounded screw heads, cheap hardware).
It came with an extremely junky plug. In fact it was broken when the unit arrived. No real problem for me anyway. I added about an extra 10ft of wire and a set of gator clips(as on battery chargers) that way I can connect it direct to the battery and avoid pesky blown lighter plug fuses.

I have also ordered a Viair 70P compressor. At $39.99 it is in the same price range.I hope to be able to review it as soon as I receive it.
I am hoping for a unit that is of better build quality as my main ideal is having a dependable unit as well as a fast performer.
