Portable Travel Air Pump - Compact & Lightweight for Bikes, Inflatable Mattresses, Pool Toys - Perfect for Camping, Travel & Outdoor Adventures (Black)

Great little pump. Not too much bigger than an airpods pro case.Simple to use and no problem topping off two 700x28 tires to about 65 psi starting from 40 psi. Not as loud as I would have expected and, while the nozzle heated up some, never translated to the body.Was pleased that packaging was simple, but protective, and pleasantly surprised at the silicone case that was included. While I haven't ran it down to empty yet, I was able to complete similar "top offs" 2 times before the LED indicator flashed red (<50% battery left).This would easily fit into my jersey pocket or the keg I keep in one of my cages and, based upon my use so far, I don't see an issue bringing up 2 tubes from 0 - 65 psi (what I run my 30's at) when fully charged. Maybe even more - but at that point, you probably have bigger problems than finding some air for your tires.5 stars. MUCH better option than finicky C02 cartridges.
