Mini Bike Pump Portable Bike Tire Pump 100PSI Electric Bike Pump Mini Air Pump Tire Inflator Rechargeable with Presta Schrader Valve

Works great will pump up about three tires before needing recharged

A must for any cyclist! Compact and great for travel or to throw in your bike bag.

Pretty good little air compressor for riding with. Fills a road bike tire relatively fast and effectively, albeit it is a bit of a pain to turn on sometimes. Can't speak to long-term durability yet, but seems pretty well made and I've had good luck with most Rock Bros products.

I bought this pump back in October. Of course, pumps you generally only use when you have a flat. I had recently switched to tubeless and have been lucky to have very few problems. I used this pump twice in the last couple of months, more than anything, just to use it. A couple of days ago I went to use it and it won’t even turn on. It is fully charged (green light), but still won’t turn on. I know I am out of the period to return it, but on RockBros website they report they respond to emails etc within 12 hours generally. I have not heard anything from them when I reached out to just get some ideas on how to potentially repair the unit. I have been a big fan of RockBros things that are not electric in the past. This pump has put a little bit of a sour taste in my mouth for them. If I don’t get a response from them, I may never purchase one of their products again. We will see what happens.

Charges fast and works great. Just follow the Manuel for the on/off and you're ready to go. No more CO2s

Muy práctica cumple las expectativas y fasil de llevar

Don’t use with TPU’s unless you use the extender. I used it to inflate a tpu. It melted the valve stem INSIDE THE WHEEL. A nasty surprise it you have a flat out on the road somewhere. You can’t get it out of the wheel. Buy TPU's with metal valve stems too.

I carry this in my top tube bag instead of CO2 cartridges and keep another in my glove compartment which has been handy.

It stop working suddenly only used one time.

Works well. Small and light. A little loud when you air up your tires. Not as fast airing up as CO2 cylinder.

Great pump! Easy to use and lightweight. About the only thing I would like is a way to preset the pressure but thats a very minor thing. I own the larger version of this and it has the preset but it's a bit on the heavy side.

I purchased this unit because the cartridge air unit failed. I haven't had the opportunity to test it out on the road, but my concern is going to be the battery life. I do not have flats very often (knock on wood), so I have been relying on the air cartridges. Once I have had teh chance to try the unit on the road I'll come back and report.

Perfect little electric pump,, bought it for air travel when you can’t pack co2 cartridges. Pumps up road tires to 70 psi easily and 29 in mountain bike tires with battery to spare Does not get untouchably hot like other brands . Awesome product
