Mini Bike Tire Pump with Gauge, CYCLAMI 150PSI Electric Bicycle Air Pump, Auto Stop, Presta and Schrader Valve Aluminium for All Bike, Type-C Rechargeable Battery

Excelente producto

In general, the design is fine, the size is ok for cycling purposes (you don't have many pockets to carry things on), but it has two flaws that completely detract from the product.The least serious is that it is not possible to change the default pressure with which you turn on the device, in this case 100 psi. So if you are riding MTB, every time you use it you're going to have to be adjusting it to automatically inflate it. Those bikes tires regular pressure something like 40-45 psiBut the most serious thing is that, if you don't use it for a few days, when you're going to turn it on, it won't do it, and unless you plug it back into the charger, it won't turn it on again. And this even when you've saved it with the battery almost full.The funny thing is that the time it takes to be ready again does not correspond to the time it should take to charge a battery that was completely discharged, which is what it seems when it does not turn on again. Actually is a lot shorter.And yes, I'm writing this review because it wasn't an isolated fact. It's happened week after week since I got it.Unless my unit is defective, and if what has happened to me is how it normally works, I cannot recommend this product.

Took a chance and glad I did. I always check and fill prior to a ride, now I take this pump with me and use at the start.

The first one sealed when airing up during first use, but not there after. I returned for another. This one seems better. It does get a bit hot after extended use.

Producto en perfectas condiciones, vendedor cumplido!

This little air pump is awesome! Highly recommend

Llego dañado, no funciona porque no se puede cargar la batería, es decir, la batería no recibe carga y no prende.Ademas el proceso de devolución es bastante difícil y hay que pagar el envío de la devolución el cual es costoso y demorado y por lo tanto se demora la devolución del dinero.

I just got this the other day and threw it in my bike bag after charging it. It’s insanely small so I wasn’t sure how well it would work. You hold the power button down for a little bit and then it has an audible indicator. It comes with all the attachments you need. The only thing is trying to figure out what psi it’s filling up to. I basically pushed it on my mountain bike tire as they were very low. It filled it up in just 5 to 10 seconds. I checked with my pressure gauge and I actually overfilled by a little bit , but that’s fine. It filled it up with no problem and it was quick. This is great to keep on you and takes up little space and weighs almost nothing. You can easily throw this in your bike bag. I always keep a small bike pump in my backpack, but this is so easy just to fit on the bike bag and weighs so much less so I’m going to be using this a lot more. It actually feels like a really high-quality too. It’s very solid.
