TowerTopTyre Inflator Air Compressor: 2X Faster Heavy Duty Car Tyre Pump Portable 12V Digital Tyre Inflator with High Precision Pressure Gauge, Memory Function, 1 Min Inflation, LED Light, Handbag

The pump seems well designed and solid. It is quiet in operation and inflates the car tyres at a good speed. My tyres are fairly big ones (235/60 R16) but it copes with no problems. The pressure gauge readings appear consistent with my other PCL pop-up pressure gauge. One reason this product appealed was that it is rated at 30 minute operation (before you need to rest it) compared to many of the top sellers that are only 10 or 15 minute operation. This pump has got a fan which runs continuously when the unit is connected to power - which seems a bit strange. I would have expected it to be connected to a thermostat or something so it would only operate when the pump is hot. In any case, the fan seems to work well because I used the pump for a few minutes and the temperature afterwards was still cool. There is another strange feature. You set the desired pressure setting by means of a turning button - eg 29PSI. Then the unit will inflate until the pressure reaches the requested pressure PLUS another 1.5PSI - so in this case it would inflate till it reaches 30.5PSI - this is to accommodate the slight pressure drop when you disconnect the pump. In itself this is a good feature. However the strange thing is that there seems to be a feature of the programming whereby between 29PSI and 30.5PSI, the current pressure of the tyre is not updated so it stays on 29PSI so it looks like no air is going into the tyre. Only when it reaches the target (30.5) will the unit shut off and the indicated tyre pressure will suddenly be updated to 30.5. This is all fine once you understand this quirk.In summary this is appears to be a well-engineered unit where the manufacturers have clearly worked effectively to address the issues of pump-fatigue caused by high temperature and pressure. Whilst I have only had a it a day or so, it feels like it should keep working for a while.

best 12v pump I’ve ever had there are cheaper ones if you don’t mind waiting all day to inflate your tyre yes I’d recommend

Very good and works well. Only problem is the connector to the valve, very hard to take off without losing a lot of air. I order a short extinction for it and now work well.

Bought this item and was very impressed with it, so easy to use and setting your required tyre pressure, it's very fast in inflating your tyre and not too noisy ,it comes with a protective carry case for easy storage, I strongly recommend this item 100 %

Very pleased with the tyre inflator. Works well and quickly,easy to use and well worth the price.

Like the large buttons, auto shuts off and storage case.Excellent piece of equipment.

Inflates a tyre reasonably quickly, stops when it hits the right pressure. 12v socket lead is a useful length.My girlfriend liked it, so I bought her one! Can't really recommend it more than that.

I struggled to get this to work on the one time I have needed it. I ended up limping to a garage (on the motorway in the middle of a cold Winter night) & paying the small fee to use the industrial scale tyre pump in the petrol station. I then drove home trying to work out how many times I would have to use the garage air pressure facility before I covered the cost of buying this item and it was a lot. Given my car constantly monitors the tyre pressures and tells me when I need to use the air, this pretty much makes this item redundant. A novelty I now keep on board in the vague off-chance that I may one day come across someone in distress who may need to borrow it (and feeling I have as much chance of that happening as I have of winning the jackpot on the lottery). One of those impulse buys the internet is famous for. I'd recommend putting into a pending basket, thinking about it for a couple of days, then buying something else.
