I have had some very good experience with a Electric Air pump which works off the lighter Socket in a car, most of the stuff u get in the market though are crap,
I have a full metal pump which costed me about 2500 bucks, doesn't make a racket while it inflates and it saved my backside 3 to 4 times on the highway when I had a puncture on my tubeless tyres.
The time it worked on an Endeavour on a flat tyre really shocked me, no hardwork, no nothing, just wait for 5 minutes.
However, if one ventures into the total wilderness, a leg pump is definitely a good backup

I used a footpump for well over 15 years. Then I switched to an electric pump around 1991. Age catches up with you at some point, and you do not appreciate the foot/leg exercise. The foot pump was 10-12 kicks per psi.
I have always used the cheap unbranded pumps (Rs.600-800) and hand over the old one to the new owner whenever I sell my car - say 6-7 years. I have had to replace a pump earlier only once, as the pump will not pump adequately. Otherwise towards the end of its life (with me) what I find is that sometimes the rubber sealing bit on the tyre end starts failing, which the pump is still fine. The gauges do fail, so I keep a separate gauge with me.
It takes about 3-4 minutes to go from 20psi to 30+ - not too bad in my view.

Pumping slowly would increase pump life - heat generated will be lesser.
@Satya : @2500, you could get 4 double-barrels from Metro. 3 levels of back-up :-)

I used a Chinese made Air Compressor, created lot of noise but was good enough. Only drawback, can't let it run for 5 mins continuous... Ran for 1.5 yrs and then one day left it for 5 mins and it went Kaput.
Have a foot pump now. been using for a while it's fine. Prob is the nozzel goes for a toss after a while.. something related to the rubber part in it (According to JC Road Store Owner) and needs replacement now and then.
But for Rs. 200 INR , the Chinese Pump was worth it. Had got it from Dubai. Damn cheap stuff there.

Went to a Hyundai service centre yesterday to attend the free car checkup. There was a cute chick sitting at a table holding a competition of sorts. You were to basket a ball in three attempts. There were prizes for zero, one, two and three baskets. The minimum guaranteed prize was a tyre pressure gauge. It's like a pen, with a valve at one side and a sliding ruler on the other. You press it against the tyre valve and the ruler slides out to a position that will tell you the pressure.
The one I received, I asked if I could verify its correctness. She handed it over to a mechanic working on an i10 nearby. He checked the front right tyre pressure and it read out 32psi. That's more or less the pressure in i10 tyres, so I assumed it to be correct. Later I got two more so I could gift it to my uncles. When my car returned from the checkup, I used all three gauges on each of the tyres. Two of them seemed to be giving similar readings, while the third was off by a good 5 psi. So I got it exchanged. Again, one of the three was always off the mark by 5 psi. Also the two which showed similar readings never showed exactly 30psi in my Santro's tyres. Since tyre pressure check was part of the checkup I assumed (and confirmed with the supervisor) that the pressure in all tyres was 30 psi. None of the gauges on none of the tyres reported 30 psi. The left rear tyre even showed 15psi!! I shrugged it off saying the gauges had probably exhausted their quota of useful readings.
On the return journey I halted at my uncles' places for some other work (apart from gifting them the guages). After I left, I stopped at a tyre shop and got the air pressure checked. The mechanic asked me if the left rear tyre had a puncture. I was surprised. He then said the pressure was only 10 psi! Since I was travelling alone and it was a tubeless tyre, I got it re-inflated and went off home. But it again poses a nagging question: Are these gauges actually reliable?
The person sitting beside the cute chick, when I asked them about the discrepancies, coolly told me not to expect reliability from something that was given away free. He also said a genuine and reliable gauge sells at Opera House for about 7.5K.

I've always noticed a difference between the reading shown by foot pump gauge and the one at petrol pumps - the digital display type with auto cut-off mechanism. When I fill say, 32 psi using foot pump and take the car to a petrol pump soon thereafter, the reading in the digital gauge is only 25 psi. Assuming the petrol pump gauge to be more accurate, now when I use foot pump, I keep pumping till the gauge shows 40 psi. But then I have noticed that even the digital displays at different pumps show different readings! Don't know which one to trust.

I have been using a reputed American 12v electric tire inflator made by Coleman, the camping specialists. The trouble with that are:
1) it makes a racket, attracting unwanted attention
2) It takes ever so long to fill say 5 lbs. If the pressure is 10 lbs less than the recommended pressure, in my case 32, it takes much much longer
3) after about 3 to 4 minutes, it gets heated up and shuts itself out.
Now I am planning to pick up a foot pump. Not sure if the Slime double barrel Heavy Duty Pump is available in India. It sells for about US$20 in Amazon.com
I have also been quite bothered by the inconsistencies in the accuracy of the pressure gauges. I have a cheap Chinese electronic one, which is always at variance with any gauge I have tried. The trouble with the pencil type is that dust can get into the barrel and will cause it to be inaccurate. Every gas station I have tried shows different pressure. Now I have arbitrarily selected a station near my hose and I go by what the electronic gauge there says. An accurate gauge is my Holy Grail. Can anyone pl. help?
