It works great for electric bicycles and the motorcycle, I've not needed it for a car tire yet, since I don't have a car. I'd been carrying a full sized bicycle pump for the last few years, and finally got one of these little portable rechargeable electric air compressors. So far its been working awesomely, and takes up just a tiny bit of space in my backpack. Glad I took a chance on it! I usually end up airing up several bike or motorcycle tires before I remember to recharge it.
