Nice pump, but get the attachment hose
I am using this to replace CO2 cartridges when I get a flat (out on a ride) with my MTB or road bike. It works well to inflate a 29 x 2.6 tire up to 20 psi, which is fine. But on my road bike (700 x 25), I’ve only gotten it up to 50 psi. That’s barely enough to get me home.Also… if you use TPU inner tubes instead of traditional rubber tubes, this little pump can melt the plastic valve, because it gets pretty hot when pumping up the tire. The solution is that you need to buy a separate attachment hose they sell for around $9.00 on Amazon. It will get the hose hot, but not the plastic valve on your inner tube.UPDATE:The small attachment hose is definitely worth getting (need to buy separately). It creates a much better seal when the tube is screwed into the inner tube valve. I am now able to get my road bike tire up to 90 psi, which is plenty. Also, the unit doesn’t seem to get as hot when using the attachment hose.

Works OK, was a little hard to get it to fit
Seems to hold a charge, the problem was getting it to fit on the Presta valve and holding it on there until it really starts to kick in. It starts going but doesn’t do much until it gets really noisy (i.e, a higher whine). Then it seemed to work OK, although the tire never seems to get full, as in 100 PSI full for a racing bike. Only used it twice in the garage. If it saves me when I get a flat out on the road, maybe I’ll give it 5 stars. Until then, not bad, not perfect.

Failed to charge and power up
The pump would no longer power on or take a charge after 10 months. I used it a few times to fix flat tires but eventually it stopped taking a charge.

Once I get confidence in this, I will leave The pump that I now carry on rides at home.
This one works. It has no gauge and no hose. It comes ready for presta valves. It says you can use it for the other valve as well, but I don’t need that so I can’t comment on it. I had returned one of these gadgets that had a gauge and a hose. When I’m on the road and I change a flat I want the simplest possible solution. This is it!

buena pero incompleta
Buen producto, pero cuando te llega te enteras que debes comprar una manguera extra porque puede dañar la válvula de la bicicleta si esta es plástica

My husband loves this tire pump. It’s the perfect size to care in his under saddle bag while he out on long rides.
