Amazon BasicsPortable Digital Air Compressor, Dual Battery Clamps with Carrying Case, Black/Red

Cast metal and hard plastic casing makes this a very sturdy unit, and a bit heavier than it looks. It's also more compact than pictures suggest and fits snugly along with all accessories and coiled air-hose into a neat 9-10l decent quality carry-bag.The unit has a fixed LED display plus a built-in LED torch which has its own separate on/off switch.Supplied also are some adaptors for football and leisure inflatables, and a spare in-line spade fuse, but no adaptor for Presta bike valves, (although such an adaptor would be a cheap and easy-to-acquire purchase if required).Power cable is flat-figure-8 with an in-line fuse and is sufficiently long to reach from under-bonnet +ve and -ve battery terminals to kerb-side where it is likely to be sited. Coiled extending air-hose is substantial with good quality spring-loaded feel, and which will stretch plenty 'nuff to go round to the rear of the car without re-siting the unit or putting unnecessarily stretch on the power cables.NB this inflator's electric motor has a higher current-draw than most single-cylinder compact tyre compressors, so it must be used on a high-amperage circuit or directly to battery terminals - using it with a cigar-socket or accessory terminals will probably blow fuses lower than 30A and/or cause the car's wiring to overheat.When switched on, first impression is how the two cylinders balanced operation and rubber feet isolation creates less noise than expected: it whirs rather than clatters, making it rather more neighbour-friendly than many other inflators at this price-point.In operation the unit can inflate a modest 225x65xR17 flat tyre to 2.5 Bar in around a minute and topping-up from 28psi to 36 psi in around 6 or 7 seconds, making this one of the fastest non-hgv compressors I have used. Because of the fast flow-rate, I have never had to make the unit work hard or stay on for an extended period, which would involve pausing operation to allow cooling down as is recommended.The red LED digital readout is clear, and has three operating buttons to set and control auto-shut off. I found the shut-off to be accurate when checking with another gauge, however the subsequent displayed pressure is slightly lower than actual, making you think it still has a little way to go. Armed with this information I have found no need to repeat operation as it will then over-pressure until the sensor is reset: this is my sole quibble with the product (if I could drop half a star..), and by no means a deal-breaker.Great quality product at the price, and a must-have for your car or van's weekly checks or for emergencies, or for those who want an fast and efficient inflator, but don't need a professional capacity compressor for power-tools or professional use in garage or workshop.Edit as follow up to original review:- three years on this thing is still going and just as powerful as when purchased. I lost one of the rubber feet which came off and I couldn't find it in the dark so got another one which looks diffent but fits, (should have used the LED torch, shouldn't I?)I went through a period of a few weeks when due to road debris I had a couple of slow punctures which necessitated topping up every day until I bit the bullet for new tyres. Pressed into daily use it never failed, never overheated and the hoses and seals are intact and doing their job. I found that the screw-on valve fitment as supplied was fine but a bit foutery for cold fingers in the winter and necessitated taking gloves off so I bought a short hose extension with quick-release lever for Schrader valves (£7), screwed it on and just left it in place on the airhose where it can be attached and removed from the tyre valve in seconds without stripping the hose threads, (as can happen when impatience to get on the road is a factor). Problem solved and makes this a more user-friendly compressor, especially with winter mitts on.

Well what can I say, what a fantastic pump for the price, inflated the tyres to 65psi no problem on my campervan and in no time at all, plenty of length on the hose that stretched from the front to the rear of my 7 metre van, can't fault it at all

50% faster than conventional pumps and quieter too, more of a deep hum noise than a noisy rattle.Long power cable and long coil wound air line.Connect red clamp to positive, and black clamp to bare metal. Easy.

Runs smooth, rubberised connector on the air hose is a nice touch as are the rubberised power wires. Flexible air hose is not long enough for my application. Need to stretch it quite a bit which puts strain on the electrical wires and pulls the clamps off the battery. This is why I have docked a star. Carry bag is cheaply made but what can you expect for the price. Pressure reading is a little out but it takes nothing to adjust for the correct tyre pressure. Some complain about the accuracy but forget that this pressure reading is measured at the pump where it has to push the air through the hose, past the valve and into the tyre. This creates extra pressure on the pump side and most pumps read high because of this. All in all a good product, how well it lasts will be another thing but to me the signs aren’t bad as it is well balanced.

Just took delivery of this yesterday. I was looking for a tyre inflator for my motorhome (80psi) and this was my third purchase - two previous inflators had been useless (returned for refund). This inflated all four tyres from 60 to 80psi within minutes. Relatively quiet in operation. Nice long hose made reaching all tyres easy. Battery clips easy to apply. Maybe only negative comment is that storage bag doesn't appear overly robust. Early days but I would not hesitate to recommend.

A little too fiddly to set up. Digital display probably not worth the effort of setting up the reading

I bought this pump as i have a fleet of vans and burnt out several smaller pumps. It makes short work of inflating van tyres to 65psi and is not as noisy as others iv previously tried. Would recommend

Bought for use on my mower,tractor and their accessories as it has battery terminal clips rather than a cigarette lighter adapter. Works very well!
