Desperately needed an air pump for my rides after the foot pump I had gave up. Nobody here seems to have reviewed any pump properly, so thought of writing a small review here.
This is what I was using for the last couple years or so. Its an all metal foot pump. AFAIK it is made by some small time company in Poona. Got it from some place near Gnyan Prabodhini. Not sure if its also made there itself. Pressure gauge has been quite useless from day one. Seems like this is not just a foot pump but an exercise machine which is designed to strengthen the user's leg muscles and test his patience. The reason for this may be that the nozzle at the end of the tube is just pathetic. It used to work ok with my bikes but it just did not like car tyres and had never fit well around it and would allow air to escape. As of now it is no use even for bike tyres, as it allows more air to escape than you can possibly fill thru fast pumping.
Lesson learnt - these plastic nozzles are prone to much faster wearing (at the point the lever touches the inner piston to depress it and drive the pin into the tyre valve. The plastic pin is also prone to breakage). Try and get a pump with a nozzle that is wholly made of metal (including the inner pin). I had a pump made in Gujarat (Rajkot if I recall correct), that was much better than this and lasted longer too.
This is what I got few days ago from eBay for about 500 bucks. Received it in damaged condition (outer case almost in pieces). Will send it back to the seller asap. Tried operating it, with the following observations.
1) As can be seen, Glowfast is printed as the name of the company on the box. Thought this was Chinese stuff, but Glowfast Electronics has a website (please Google it) with few other products including more expensive air compressors. I guess they must be importing the stuff from China.
2) Pump build quality is nothing to write home about. It is however pretty small and weighs just about 500 gm.
3) Moderately noisy. You don't want to run this near peope's residences esp. at night.
4) Topped up 4 car tyres with about 3 psi (approx) in about 10 - 15 minutes or so.
5) There is no switch on the pump. You will have to use the car ignition key. This is the most serious deficiency of this pump. Try to get one with a swtich if possible.
6) I used it from the ciggy lighter off the battery without the engine running. Don't know how bad that is for the battery as the wattage of the pump isn't mentioned. You better run your car after using this thing to recharge the battery.
7) The seal that the pump nozzle mountains on the tyre nozzle seems pretty good. No audible noise of any air loss. It also fit very easily on car and bike tyres both. So the nozzle seems much better than what I have seen on Indian foot pumps.
8) The pressure gauge on the compressor is not totally useless like what I have seen on Indian pumps. Tho you definitely shouldn't rely on it esp. since the least count is quite large - it is calibrated right upto 300 psi! Really dumb thing to do. But at least the thing does help to give some indication as to how much you might have topped up.
9) Gets heated up quite fast, and you better let it cool off (see picture for details about that).
Overall, I find this thing worth having for topping up car/bike tyres. For biger tyres, I don't think this model is a great idea. Nor do I think its good for pumping up completely flat tyres. So I'm not sure how useful it will be in emergencies when you have a flat.
Lastly, unless this thing lasts a few years, its a waste investment. But I'll get to know that only with time. Any users have any comments about its durability?
