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

It stop working suddenly only used one time.

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

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

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

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

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.
