AUTDERCordless Tyre Inflator, Portable Air Compressor Pump with Digital Pressure Gauge, 180PSI Max for Cars, Motorcycles, Bicycles, Balls

I had to invest in another tyre pump because the Jeep cigarette lighter and the Jeep power plug is only fused at 7 amps so I could not use my original electric tyre pump which takes 10 amps .After looking around I found this Autder cordless tyre pump .Yes it was expensive but the thing that I found very useful was that it actually comes in a fitted zip up case with the tyre pump , battery , battery charger and all the fittings + the user manual .Once I had charged the battery I tried pumping up all 4 tyres on the Jeep which was very quick and easy to set the tyre pressures and also very quick to pump up all 4 tyres .I have only 2 criticisms namely :-1 - Even on an overcast day the display israther DIM and you have to get it at justthe right angle to be able to read it .2 - When I saw that the battery was 21volt2amps I thought oh good my leafblower battery is 21volt 4amps I will beable to have an extended run timewhich will be useful going by otherreviewers saying that the batterysupplied does not last long enough totop up 4 tyres .Unfortunately my leaf blower batteryalthough the right size and type theslide on fitting was different ! So I hadto buy an extra Autder 21volt 2ampbattery which I have charged but notactually needed because the original onehas not needed recharging even afterseveral tyre top ups ! I keep the extrabattery charged with the tyre pump - justin case .Apart from the above criticisms this is an EXCELLENT tyre pump well worth expense .Well done Autder !

I received this item recently, it was extremely well packaged. The item itself is very sturdy and appears to be well built. It comes with two leads, one to charge the battery which must be performed with the battery removed from the unit, the second is a backup 12v lead which powers the unit from your car battery should the unit's battery be flat. In addition there are several attachments for charging bicycle tyres, beach toys, footballs etc. All of this comes in a handy carry case which is sectioned for ease of storage. My advice is to read the instructions before first use as this will explain the button functions which are pretty straight forward and advise you to fully charge your battery as it arrives only part charged.I have used this several times now and have been extremely impressed by the speed of inflation, the accuracy of the PSI readings and the noise level. I have had reason to contact the supplier direct and only have praise for their level of customer service. Based on this I can wholeheartedly recommend this portable compressor.

These are much the same product from a range of manufacturers. I chose this one because of the stout hose connection and the traditional clip valve connector as opposed to some screw on ones which end up being cross threaded or losing tyre pressure when attaching. I'll work on the good points first, it is well packaged and the travel case keeps everything safe whilst in your car. The product itself looks and feels good. It is easy to use, it nicely stands on it's own or you can hold it comfortably. It is extremely portable. The readings are clear. The multi-functions require a little getting used to. Now the bad bit....its underpowered. It really needs a battery twice or three times bigger. The higher pressure ranges take ages to get to, (I'm talking of 62PSIG not 130) and this is only as good as the battery charge will allow you. Would be better if there was a battery override and spare cable for the car cigarette lighter socket. Power is the big issue, I don't doubt other makes are similar. Check 4 car tyres and finish inflate 2 caravan tyers on one charge - not a chance!

I bought this to replace a Bosch Easy Pump which lasted just 1 year and 7 days, which was a great pity as it was a very small and efficient pump, that is, whilst it lasted. Perhaps, in hindsight, I was expecting too much from such a small unit powered by a 3.6v battery, that technically developed 150 psi, and made a very loud chattering noise when generally topping up my car tyres within a typical range of 32 to 36 psi.So, in choosing a replacement, I spent quite a lot of time researching, and I am grateful for the helpful comments left by other Amazon customers. In the end, I chose the Autder and having used it about 6 times on various cars I am very pleased with its fast, accurate performance, delivered at a relatively low noise level. A 21v DC power output, capable of delivering 180 psi, should mean that it has lots and lots of spare capacity and in terms of its typical every day usage, is not operating at anything like its capacity, which I am hoping will result in a long life.Given that these pumps generally 'live' in car boots, it is great that it come in its own zipped case and that case has a pre-formed foam liner to keep it from the inevitable knocks and bumps. Of course, it has more uses than inflating car tyres and comes with a range of attachments to also blow up air beds, footballs, bicycle tyres etc. and the air pressure range can be pre-set - as well as a target psi which, when reached, automatically switches itself off.

Great while it worked. When battery ran out it failed to charge. Contacted autder who said i wasn't using the right charger even though it was the one in the case. They sent me a new battery. Same thing happened . Even tried the car charger that came with it . Shows charging but the actual display shows no charge when you turn it on and I dies after about 5 seconds. I'm not stupid and know it's not me doing the wrong thing. Complete waste of my money and not helpful as I have a slow puncture
