BEAUTYOVOElectric Bike Pump - 120 PSI Cordless Bicycle Pump with Pressure Gauge, Auto-Off & LED Light, Presta & Schrader Valve Compatible

The media could not be loaded. This pump was relatively new to Amazon and most of the reviews were by people who got them free so I was a little nervous paying full price. Fortunately I've been delighted by this little marvel.The pump comes with a storage bag, flexible hose, USB charge lead, ball pin adapter, schrader and presta valve fittings so everything you are likely to need. Being lithium it is shipped only partially charged so must be fully charged before first use. However, it charges very quickly.To use the pump simply screw in the required valve fitting, turn on the pump with a long press of the power button, dial up the target pressure, fit the pump to the tyre valve and press start. The pump starts quickly and runs until the desired pressure is reached, and then it stops immediately. A double press on the up button turns on a small lamp which might be useful on night rides.It took just over a minute to fill from empty my Butcher 27.5 x 2.6" tubeless tyres to 22 psi (see video). I also filled my road hybrid to 70 psi with no problems in around 2 minutes. It is noisy but not overly loud. It does get hot so if doing a lot of filling you will need to take breaks for it to cool down. I pumped up 4 tyres one after another and still had plenty of power left for more.The built in pressure gauge and auto stop are very handy. I compared it against my existing Ryobi digital type pump and topeak shuttle gauge, which both read within 0.5 psi of each other. The mini-pump does not seem as accurate, at 20psi it was pretty close, but above 70 psi it seems to over-read slightly. That said the target pressure achieved in the tyre measured close to the desired value so I'm not worried.The pump is small enough to fit in my small frame straddling double storage bag, but I only carry the valve attachment to match my mtb to save space. It's not sealed and needs to be stored away from the elements, so I've put it into a small plastic bag.The only problem I've encountered is one of my presta valves was slightly restricted by tubeless compound. This obstruction caused the pressure at the pump to rise faster than the actual pressure in the tyre and led to a false stop on the pump. To overcome this I had to set the target pressure higher and pause every so often to check the actual tyre pressure. Changing the presta valve for one that wasn't blocked solved the problem.Overall it works well, much faster and a lot less effort than a manual pump, so I'm very pleased.

After having been disappointed by a few other small-size-high-power pumps, mostly because they failed to fill more than a tire on a single charge (and even that not consistently), I read (on Amazon) the positive reviews for this little one and decided to try my luck one last time.And I'm happy that I did: it's even smaller and lighter than its counterparts, has a very clear & sharp OLED display, and -- most importantly -- I had no trouble to fill a couple of almost empty bike tires up to 45 PSI each, and the battery had still plenty of juice for more.The pump did its job fast and auto-stopped when the right preset pressure was reached.Obviously, it is delivered with all relevant accessories to enable filling not only bike tires; a nice textile bag (to keep everything tidy together) is included as well.Besides the fact that it gets quite hot when in use (common issue with ALL pumps I am aware of, cordless or otherwise), there is really nothing I can complain of - praises are due!From my experience, highly recommended!

I like this pump as its small and light weight not quite sure how to use it properly quite noisy but good quality material

Had this pump for a few months. Never let me down. Used many times to top up tubeless tyres on multi-day rides.I particularly like the fact that you can set the target pressure on the digital readout and see how the pressure gradually increases when inflating.Would be nice if it came in a protective case but I’ve just shoved it in a surgical glove to avoid any water problem.

Cannot reach above 40psi. Overheats

Form factor / size is amazing.

Used multiple times with a leaky tyre until it was changed so he could keep riding. Very quick to use, small and light.

The media could not be loaded. I can see that this is a nifty little tyre inflator and very handy to take on a bike due to its size and speed.I tried it (well my husband did!) on his road bike which uses a presta valve fitting. the kit does come with an adapter but he tried it twice and said that it wasn't a great fit and that it leaked air badly.He's going to try another one off another machine to double check itIt got to around 60psi and then it got super hot (hot enough that he couldn't hold it) and had to leave it to cool down.Will review my review once we have tried it on a few more things and giving it the benefit of doubt for the moment
