BOSCHElectric Bike Pump, Portable Air Pump, Cordless Tyre Inflator EasyPump (3.0 Ah battery, 3.6 Volt, Autostop function, 150 PSI, 10.3 bar, LED, rechargeable via USB-C cable, in carton box)

Why did you choose this product over others?:Excellent device. Pumps up tyres with a section of attachments. Having to auto-stop function makes it easy to set the pressure and it cuts out when it hits it. Such a simple way to pump up car tyres, bicycle and and airbeds when camping.

I was skeptical at first because I couldn't see how such a small unit could inflate a tyre to 30+ PSI. I was pleasantly surprised. This is a very cleverly designed unit. It's mostly aimed at bike users but it has enough power to inflate car tyres (might take a while though). I like the display, which illuminates, and the accessories which fit neatly in the front. The charging is done from a USB-C port which is convenient and possibly annoying because it takes a while to charge. For such a small and convenient unit, it's amazing.

Hands down, the best portable cordless (small form) tyre inflator. I have tried many, and often the biggest problem is the ability for the battery in the cordless to last long enough to reflate a completely flat car tyre. This one does it, with spare capacity. My test is on a totally flat 225/50/18 tyre to take it to 2.7 bar. Most get half way. This does it completely. The bigger ones do it without issue as well, but the point of this is that it something you can put into a car’s emergency kit which is self contained, without huge extra bulk, that can also be used daily. It works in my motorbike pack, my kid’s bicycle kit, pretty much everywhere. Best pump investment yet.

For years I've been using a good old-fashioned foot pump - it works, but with increasingly big tyres (on increasingly big wheels) it takes more and more effort to top them up with air. So although this Bosch item isn't specifically for car tyres (and indeed a couple of the reviews I read relating to car tyres sounded like maybe it's not the right device), I thought I've give it a try. It's thoroughly impressed me, and makes me wonder why I didn't buy it (or something similar) years ago! I have big 21 inch tyres on my car and this gadget adds a couple of PSI in seconds. It's incredibly convenient to be able to dial in the pressure you want, screw the device to the tyre valve, and simply let it do its thing. I read a couple of other reviews that suggested the battery is quickly depleted when topping up car tyre pressures, but so far I haven't found that - in fact I put it on to charge after adding around 2psi to each of four tyres, and the battery meter shows the device is still full. My only concern is the accuracy of the pressure reading. Having used the Bosch device to set the tyre pressures to the desired level, the car TPMS monitor now shows they're 2psi over target, and my own separate pressure gauge shows the same thing. I'll do a few more comparisons to decide if it's the Bosch pressure gauge that's inaccurate, but right now it looks that way. However, if it's reliably always indicating 2psi over the 'real' pressure I can live with that, by dialling into the Bosch a target pressure 2psi less than actually needed.

Good tool works well, battery charge lasts a long time only boggle for me is it let’s air out when you unscrew it. I personally would buy one with a lever release if I had to buy one again.

I have looked at this pump for a long time and I was undecided whether to buy it or not. I was caught short on a recent journey away from home. I had a slow puncture. I eventually found a service station with an air pump and managed to inflate my tire enough to get me home. It was an intimidating experience so I decided to buy this pump. I have used it and it does everything Bosch said it would do. Being cordless makes is so convenient and easy to use. It’s USB charged so you can charge it in your car if necessary. I am delighted with this product and it’s safely stowed under a seat in my car. A good buy.

I love this. Only arrived yesterday - to replace a "cigarette lighter" socket tyre inflator that was large bulky and VERY noisy. This is very very much better. It is easy to set up. Both my cars are electric now and the old plug in inflator was very awkward to use. So far, it's as good as it looks and does a great job.

Excellent piece of kit and extremely portableThis was purchased for use on our cars and has been used on my wife’s car to inflate a very soft tyre and it worked a treat.It would struggle to inflate more than one tyre at a time but has a reasonably quick recharge time via usb which means you can charge on the go which makes it very versatile.I would happily recommend this product.
