This is my first portable battery operated bike pump so I cannot compare it to others in real usage. I read and watched reviews on every one I could find in the price range and size I wanted. This one stood out for many reasons: size, speed, battery life, 2 year warranty and it can inflate car tires as many out there say in small character'' not for use on car tires'', this one is! The moment of truth was when I used it, it works great, pumped up my bike tires from 30 psi to 50 psi in no time. The noise level is very acceptable for what it is, it's a air compressor so it will make noise! As for the actual battery life, it stayed full bars but I only pumped up two tires with it. Comes in a nice little velvet pouch for the pump and accessories. Time will tell if it will last a long time but from what I can feel and see, it should, the build quality is really good and solid! Very happy with this little pump which I will ad to my e-bikes' carry bag. If you ride a bike often, you need a pump and a flat repair kit for sure and in my book, this little unit is a winner!
