Bosch Electric 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)

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.

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 have used it for my car to refill the tyres when the pressure is low. I have never had to use it for more thantwo tyres and the battery has been reasonable not loosing more than one out of 4 bars when used for 3-4 times. I dont know if it would be enough to fill from 0, all4 tyres. It is very easy to use and charges very quickly. It stays in the car for emergencies

It's a good product, I come back with the review after 1 year. It has some limitations, your lucky if you can inflate both tyres of the motorcycle with one charge of the battery.It's perfect for just adjusting the pressure. Takes about 4 -5 minutes .For a full pressure,one wheel.

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.

Excellent piece of kit compact and powerful but then it's Bosch a name you can trust.

An excellent pump

Coming across this by chance, and having several different types of tyre inflation devices, I wondered if this was something worth buying.I have a garage compressor which is great for motorhome/car tyres, and great for bicycle tyres, especially from flat when fitting new tyres or having topped up tubeless sealant; a track pump which I've had for yonks and is handy for a quick top up of bicycle tyres instead of having to use the compressor; the motorhome has a powerpack/jump starter/compressor thing in it which is handy for topping up tyres when away if needed; my car has one of those small 12V compressors which, again, is handy for any emergency and my saddle bag has a Lezyne micro pump in it for any occasion when out cycling on any of my bikes.So, why would one of these be any use I wondered?When we go away in the motorhome I usually pack the track pump, but it's not the easiest thing to pack and ends up getting in the way! The powerpack/compressor thing is a bit unwieldy just for doing bicycle tyres and the micro pump, as good as it is, can take a loooong time to pump up a 29" MTB tyre from flat if I've had a large enough puncture that the sealant can't deal with and I've had to put a bacon strip plug in and then inflate the tyre from flat.I thought this inflator might be of particular use for use with my bikes, and the rest of the family's bikes too (which have a mixture of presta and schrader valves), so took the plunge and bought one.So far, no regrets. If I'm out for the day cycling I'll usually have a small backpack with me, and this is compact enough that it can pop in there without adding much weight.I needed to add some air to my MTB the other day at home and decided to grab this for the job. Topped the tyre up easily and relatively quickly - obviously not as fast as a compressor or a track pump, but way quicker than a compressor when you factor in turning the compressor on and getting it up to pressure and unwinding/rewinding the hose on the reel, and certainly less effort than the track pump.For topping up a bicycle tyre it works a treat, and when out on a ride will make inflating a flat tyre so much easier than with a micro pump.I've not used it on any vehicle tyres yet, and if at home would just use the compressor obviously, and if away would use the portable compressor - but I'm sure this would be sufficient to top up a tyre if there was nothing else. Don't think I'd fancy inflating a car/motorhome tyre from flat with it though!The included adapters fit nicely into the body with a slide over cover so no chance of them falling out and being lost in transit.The schrader connection screws onto the valve, so no having to try and hold it in place whilst inflating.The presta adapter attached easily too, just needs a little push to be on far enough to engage with the thread. The hose then screws onto the presta adapter. I found it easier to put the presta adapter on first, rather than attaching to the hose first and trying to then attach it to the valve all in one go.The gauge seemed to be reasonably accurate. Unless you have a calibrated tyre pressure gauge, you'll never know which one of your devices is the most accurate!The cloth bag keeps it protected, the display mostly, but also keeps the hose from getting caught up during transit.Once I was happy that I was keeping the inflator I bought a case for it to just keep it protected when being stored in the garage or transported in a vehicle. When carrying it when cycling I just use the soft bag.The preset function is very handy, allowing you to set it and just leave it to shut off automatically - or, of course, you can turn off the preset option and inflate manually.Finally, the fact that it is USB charging is fantastic. For me it means it can be charged in our motorhome, and even from a small powerpack if need be.
