12v tire inflator from Sears

Posted in cars, Uncategorized with tags , on October 1, 2017 by marksun


Price:  ~ $60.

Got one of these from Sears to boost chronic low tire pressures.  So far so good after one use to boost pressure on four tires on a Prius from 25 to 35 psi.  This took about two minutes on each tire.  The hose connector screws on easily and securely with minimal leakage.  I liked the screw in design better than those with flimsy clip on levers or even standard gas station inflators.  The pressure gauge is quite accurate.  I checked tire pressure with a standard tire gauge to check on it.

Does not have automatic pressure cutoff feature – personally I wouldn’t want one as it adds breakable complexity to an already obviously low cost tool.

The spec on the box states 30 PSI.   I had concerns about this as most tires need more pressure than this.  An inspection of the pressure gauge shows pressures well above 30 PSI.  Obviously, the 30 PSI spec is meaningless to me.

I didn’t find much by way of reviews before I bought it.  Later I find  a number of reviews which point to possible durability problems with the hose connector, 12V  plug, fuse, and motor with damage reports after a couple of uses.

At this point – sorry – this article won’t help with only one usage.  I’m thinking that the design seems to be reasonably solid …  but QA issues are possible for sure;  maybe inspect the parts carefully for defects at the store, before buying it ?  And put in enough usage within the in-store return warranty period.

If it works for 10 inflations, it will be a break even value for me as I really dislike filling tire pressure at gas stations after the tire pressure light goes on.  I would pay a kid $6 to pump up my tires rather than drive down to Kamehameha Highway  which is now one 10 mile-long pothole as Honolulu build’s its rail system.

German Grand Prix at Hockenheim

Posted in cars, F1 with tags on July 25, 2010 by marksun

Controversy over Ferrari team orders taints another Alonzo victory, this time at the expense of Masa. Alonzo is quicker than Masa but Alonzo but he complains to the team that he should be let through. Team orders come down, Masa creates a hole the size of Stuttgart, and Alonzo passes. In the aftermath, Ferrari is fined $100G for violation of the team orders rule. What I Ching hexagram would describe this situation I wonder. In the fair fight, Masa should have won this race. Vettel – seriously bad start from the pole ends up coming out of turn 1 in third behind Alonzo and Masa who got past both. Could he have defended his position better or gotten a better jump off the start viz the Ferrari’s? Oh yes. The hardwsare packages may be equal at Hockenheim. Vettel has had problems starting… Hamilton doing the best he could blew by Webber on the straight on lap 1, leveraging a low downforce wing setup. Webber pits on lap 13 to be overtaken by Button 9 laps later, who conserving and pulling time out of his soft option tires, ran nine laps longer than Webber and came out ahead when he rejoined the race from pit lane on lap 22. That is some calculated racing and great execution, and Button’s strong point! Around lap 43 Webber has oil consumption problems and is ordered to hold rather than challenge. Grand Prix dot calm has the usual great race report.

Hamilton has had a tough year personally with his pop. Has this had an impact? He’s got the same package as Button and is 14 ahead in the points. McLaren leads the points, Webber and Vettel are tied, with Red Bull arguably in possession of the better car. It’s driver over the hardware overall then – and consistency shows in the points. And Luck. Next up, Budapest!
